Latest / Uncomfortable Conversations with Josh Szeps / Christmas! Food! Farts! E. Coli! with food scientist Gary Kennedy
Transcript
- 0:00Get a humans, welcome to the safe space, for dangerous ideas and Merry Christmas, happy
- 0:09new year, happy holidays, it is a time of year when we stuff our faces with food.
- 0:16And sometimes that can have undesirable consequences.
- 0:20In particular, some uncomfortable conversations around, I don't know, gas, funny smelling
- 0:25urine, tiredness after big meals, whether or not we're going to make everybody sick,
- 0:28by the way, we're cooking things at the barbecue, if you're in Australia or indoors, if
- 0:33you're in the Northern Hemisphere.
- 0:34So at this time of year, one of my favorite guests from my old ABC radio show always comes
- 0:40and joins us to enlighten us and muse us and entertain us and form us about all things
- 0:46related to food, food preparation, cuisine, health, microbiology, I don't know if it sounds
- 0:54fascinating, selling it that way, but Gary Kennedy is an absolute riot.
- 0:59He is one of the most prominent and well-informed and senior food safety advisors in Australia.
- 1:06He gets hired by the big supermarket chains, by governments in Australia and all around
- 1:10the Asia Pacific to tell them how do they have to do things, how do they have to set things
- 1:14up, how hot the things have to be, how cold the things have to be, you know, in the food
- 1:18preparation industry, what are the regulations that governments should impose?
- 1:22So he's always flying around Asia, visiting new food production plants and agricultural
- 1:27factories and stuff like that, and he's a food scientist, so he understands the microbiology
- 1:31of it, what exactly the bacteria are that can make you sick, how they make you sick, how
- 1:36they change your intestinal, everything, everything.
- 1:40You may not want to listen to this while you're literally eating food because we do go
- 1:44into some uncomfortable, scatological places, but I thought this would be a nice reprieve
- 1:50from the seriousness of recent weeks, so I hope you enjoy as much as I did the one, the
- 1:56only, Gary Kennedy.
- 2:05Australia is quite different to the rest of the world.
- 2:07Most of the world you can't just randomly add vitamins and minerals and amino acid to
- 2:12food, in Australia that makes it a medicine, and Australia's philosophy is if you go to
- 2:17a supermarket, you can eat a healthy balanced diet if you buy the right things.
- 2:22So we tend not to say willy-nilly put things in, so we don't put things in.
- 2:26We don't.
- 2:27Right, okay.
- 2:28So overseas, for example, you can buy a breakfast cereal with a cup of milk and a glass
- 2:33of cereal, you get every vitamin, mineral and amino acid you need for the day, those sort
- 2:38of things are banned here, they would be drugs, and things like vitamin gummies, which in
- 2:43some countries are lolly in Australia they consider medicine, because they've got vitamins added
- 2:48to them.
- 2:49But you can still buy them in the supermarket, but in the health section, along with
- 2:52parasitamol and the ibuprofen, and they have to be registered with the Therapeutic Goods
- 2:56Administration, they're legally medicines in Australia.
- 2:59And is that true of folate cereal?
- 3:01No, folate's got an exception, so there's a couple of things.
- 3:05So right for sale?
- 3:06Supercritical, they just make an exception for whatever they don't, they want to be able
- 3:09to put in the food.
- 3:10But they, what they did way back in the late 1990s, they did a survey of pregnant women
- 3:16who, they surveyed whether women knew that folate in pregnancy prevented neural tube defects
- 3:25of which spider bifida is probably the most well known.
- 3:29And at that stage, less than 10% of pregnant women knew folate was important in their diet.
- 3:35So they put folate into breakfast cereals and bred as a trial.
- 3:40And as part of that, they did an advertising campaign.
- 3:44And after 10, 15 years, they did another survey, and 48% of young pregnant women knew
- 3:52folate was important, so they said, oh, this actually works.
- 3:56And was there a reduction in spider bifida in Australia?
- 3:58Yeah, there has been.
- 3:59There's been a significant drop.
- 4:01And folate normally, if you weren't eating it from a breakfast cereal or a bread where
- 4:05it's been injected by evil chemists, where would you get it from?
- 4:09A healthy and diet, fruit and vegetables.
- 4:12Right, okay.
- 4:13So not eating on a fruit and vegetables.
- 4:14Yeah, not eating on a fruit and vegetables.
- 4:15So you could either wag your finger at pregnant women and say you should be getting your
- 4:18five serves a day of fruit and vegetables, or you could just put the folate in the cereal
- 4:22and start with it.
- 4:23One of your problems, if you're not that either, they're the deem pregnant, but nothing
- 4:27people who have deem pregnant.
- 4:29You can't judge these days, Gary.
- 4:31You may have been.
- 4:32Yeah, you often don't feel like eating what you normally eat with your pregnant.
- 4:40And so they found just 70 pounds of chocolate a day.
- 4:44So they found that most women will still have breakfast cereal and they'll still have
- 4:47toast and things.
- 4:48Okay.
- 4:49And the other thing that everyone would be familiar with that we add is iodine to salt,
- 4:53to table salt.
- 4:54Yeah.
- 4:55Yeah.
- 4:56We used to get our iodine from a contaminant from our odor force, a sanitizing chemical
- 5:01that used to be used in the dairy industry.
- 5:04So you used to clean pipes out in factories with iodine based sanitizing solutions.
- 5:10Right.
- 5:11Which makes sense if you think that iodine, just, you know, your grandmother used iodine
- 5:14as an acid.
- 5:15I never actually made that connection.
- 5:16The iodine that I, that, do you mean the brown stuff that I can put on a cut?
- 5:21That's the same as the stuff that I need to eat.
- 5:23That's in there.
- 5:24So they're not get scurvy.
- 5:25It's in the same.
- 5:26Or a goitah or something.
- 5:27It's goitah.
- 5:28This is in the same family.
- 5:29Scurvy is vitamin C.
- 5:30Yeah.
- 5:31Goitah is not it.
- 5:32And because we've stopped using that, because they're in our better and cheaper sanitizing
- 5:37chemicals and our systems are a lot better than they used to be, we've stopped using the
- 5:42iodine force.
- 5:43And as a result, there's been a, there was a rise in problems with low iodine in the diet
- 5:51of these thyroid problems and goitah started rising.
- 5:55So they said, right, in certain industries, all salt will be iodized.
- 6:00So again, the baking industry.
- 6:02So when you salt that's in breakfast cereals, bread, biscuits, cakes, it's all iodized
- 6:07because the average Australian eats those.
- 6:09Right.
- 6:10And we've seen a subsequent drop back in goitah and thyroid problems.
- 6:13Although I did hear on a podcast, which obviously everything you can, you hear on a podcast,
- 6:18you can take to the bank.
- 6:19Yes.
- 6:20I think that he's seen in America saying that he's seen a rise in goitahs just recently.
- 6:24And the iodine is a thing that people aren't getting anymore.
- 6:28Maybe because people are using fancy salts, but I don't know.
- 6:31Where do you get iodine in your normal diet?
- 6:34If you don't get it from, as an additive.
- 6:36From a kept cleaning chemical.
- 6:39Seafood.
- 6:40Seafood.
- 6:41Right.
- 6:42Seafood's high.
- 6:43Yes.
- 6:44He was saying have seafood a couple of times a week.
- 6:45Yes.
- 6:46Seafood is it.
- 6:47Yeah.
- 6:48Seafood is also fairly high for anyone who has these things.
- 6:50That's another thing he was saying.
- 6:51This must have been hubum and something.
- 6:53He was saying that he gets kelp powder and just puts a third of a teaspoon of kelp powder
- 7:00into like his morning smoothie to make sure that he gets, that's where he gets his
- 7:03iron in for.
- 7:04Yep.
- 7:05That would do.
- 7:06Yeah.
- 7:07There you go.
- 7:08Okay.
- 7:09The lay of the land at this time of year is that everybody is scrambling around.
- 7:10If they're in the northern hemisphere, they're probably preparing for a Christmas traditional
- 7:15Christmas feast.
- 7:16If they're in the southern hemisphere, we've tended to do things more like seafood.
- 7:20We might do picnics.
- 7:21We might do, let's start with that stuff.
- 7:24Okay.
- 7:25We're going out.
- 7:26I'm going to the park.
- 7:27I'm going to a beach or something.
- 7:28Yep.
- 7:29And we're taking along a picnic.
- 7:30Yep.
- 7:31I've got a, there's probably a barbecue or also very Australia.
- 7:35Yes.
- 7:36A barbecue.
- 7:37So I've got the barbie.
- 7:38I've also got a Vietnamese, not a deep fried spring roll, but you know the rolls,
- 7:44the rice paper roll.
- 7:45Yes.
- 7:46Probably a barbie.
- 7:47Or yeah.
- 7:48Yeah.
- 7:49So the rice paper roll that's sitting in my fridge right now is a prawn rice paper roll.
- 7:52Yep.
- 7:53Cooked to prawns with some rice noodles inside, some basil and all that.
- 7:58It's currently two and a half days old.
- 8:01Yeah.
- 8:02Take away, joint.
- 8:03Is it edible?
- 8:05I'll give you two answers here.
- 8:07Yes.
- 8:08If you were a commercial establishments and you'd kept all your fridges correct, you'd
- 8:13probably got a couple of days.
- 8:14If this is your fridge your time, no, it's past the date.
- 8:18I resent your distrust of my fridge.
- 8:20Yeah.
- 8:21We've worked together before.
- 8:22Maybe you'd poison your kids with salmonella last.
- 8:27So this is true for the, for the, for the listener, it was once the case that when Gary was
- 8:33speaking to me on my obviously radio show, I had to confess that my daughter had salmonella
- 8:39poisoning, which sounds really bad, but actually is quite a common, just tummy bath.
- 8:43That is quite common.
- 8:45And I'm convinced that she got it from the takeaway joint and Gary, because you are sure
- 8:50that all takeaway joints are up to standard that I poisoned my, my daughter.
- 8:57Well, we'll leave it in here.
- 8:59I was only feeding her raw eggs twice a day.
- 9:01Yes.
- 9:02What could possibly have gone wrong?
- 9:03Yeah, what could have gone wrong?
- 9:05Raw eggs are the most common way to get salmonella poisoning.
- 9:08Yes, that's why I joke.
- 9:09No, I don't give her raw eggs.
- 9:11So, yeah, prawn, rice pepper raw.
- 9:15There's a magical number of five degrees, which is the standard.
- 9:18And five degrees was picked after the second world war, because back then, nothing would
- 9:24grow in a fridge that was less than five degrees.
- 9:26We now know there's one or two bugs that do that we didn't know about.
- 9:29But most of the bugs that could be causing food poisoning in a Vietnamese rice paper
- 9:36roll won't grow below five degrees.
- 9:39So a commercial fridge will go below five.
- 9:42So the supermarkets, the fast food chains, hopefully most restaurants and takeaways.
- 9:47But I've got a good fridge that tells me what it is and it looks like it's four.
- 9:51Looks like it's four, you know it's four.
- 9:53There's a number that says four.
- 9:54Well, let's assume it's a good fridge and it's been calibrated and four means four.
- 9:59You're probably, it's probably still okay after two and a half days.
- 10:03Most people, though, don't keep their fridge below five.
- 10:08And if it's below five, that means the butterweights spread, it'll mean occasionally on a
- 10:15cycle.
- 10:16It'll mean that the lettuce will go will freeze and yeah, I see.
- 10:21So most people don't like that and warm up their fridge slightly.
- 10:25Your fridge should be.
- 10:26And the bugs go to town.
- 10:27Yeah, one ticket to about five degrees within a couple of hours things will start growing.
- 10:32So if the rice paper roll wasn't made well and you know, you know, like a fly landed
- 10:38on or someone scratched their nose and touched the rice paper roll, you probably go right
- 10:42for a couple of days.
- 10:43But if it's been in there two and a half days, no, probably not.
- 10:47So if the bugs can't, can't thrive under five degrees and it is five.
- 10:52Most of them can.
- 10:53Yeah, so what happened?
- 10:54Why would you not eat it after a week even if it's been in a commercial fridge?
- 10:58What's going on?
- 10:59There is one bug that actually will grow down to zero, a bug called Listeria monocytogenes,
- 11:07commonly just called Listeria in the, and that's the bug that they warm pregnant women.
- 11:12So a pregnant woman should never be eating a rice paper roll.
- 11:16Oh, and in fact, pregnant women, because this bug causes abortion, unfortunately, it's
- 11:22a food poisoning.
- 11:23Like we wanted the symptoms is miscarriage.
- 11:26So this is why pregnant women are pregnant women are to be careful about seafood and
- 11:31cheeses.
- 11:32Yeah.
- 11:33And the segment that we used to do, someone, I still do, someone rang into that and
- 11:38said, can I serve gravel acts to my pregnant daughter for Christmas?
- 11:42No.
- 11:43That's my salmon roll.
- 11:44It's my salmon roll.
- 11:45It rolls to make salmon.
- 11:46No, you cannot.
- 11:47Right.
- 11:48Right.
- 11:49Right.
- 11:50But it's similar to things like things like hummus and bubblegumish dips, soft cheese
- 11:53platters.
- 11:54In fact, almost everything on the charcuterie platter except the pickles.
- 11:58You shouldn't be eating our falfer sprouts, all of those ready, even sandwiches, if you
- 12:04didn't prepare them, all of that sort of stuff, if you're pregnant, you shouldn't
- 12:07eat it.
- 12:08But when you say that you shouldn't, if you weren't pregnant, if I ate the thing, what
- 12:13would the symptoms of Listeria be for me?
- 12:16As a healthy adult, you're probably going to be fine, Josh.
- 12:19It's in dust.
- 12:20Would I even notice would I get the runs or something?
- 12:23It really doesn't affect the healthy adult.
- 12:27The really, a pregnant woman is the obvious risk group.
- 12:30But if you're really old, so above 70, if you're really sick and that might be medically,
- 12:37and you're like, Kim at therapy, kidney dialysis, diabetes, or if you've got a medical
- 12:43condition like HIV, it's a common cause of death in people with HIV.
- 12:50If your immune system shut down, it can actually kill you.
- 12:53Right.
- 12:54But it'll be totally asymptomatic for a healthy person.
- 12:56Yeah, a healthy person, you're probably...
- 12:57That is good to know, because I have spoken to pregnant women, especially in Europe where
- 13:01they seem to be more casual about this, they're less anal about the food stuff who was
- 13:08saying, oh, I still eat the soft cheeses and I still eat all that stuff because they've
- 13:13never made me sick before, and it's very unlikely that it's going to make me sick now.
- 13:17So she was under the impression that the yardstick by which she would judge whether or not
- 13:23there was harm to her baby would be whether or not there are bugs in the things that would
- 13:27have given her a tummy upset, was she not pregnant anyway, and using that as the bench line
- 13:31for saying, well, it's probably not the harm the baby because I've never felt sick from
- 13:36it before, but she's wrong, she's your saying.
- 13:38Yeah, your judge of whether you know, you shouldn't be, well, I've never got sick, shouldn't
- 13:44be your judge if you're pregnant, you know, because one of the things, again, I've never
- 13:49been pregnant, but again, you keep emphasizing this, we think she does protest too much,
- 13:54Gary.
- 13:55No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no,
- 13:59pregnant women are their immune system is down during pregnancy, and their unborn baby
- 14:04is relying on the mother's immune system for them as well, so pregnant women fall into
- 14:09the rich group.
- 14:10Okay.
- 14:11So the first thing I'm doing if you're pregnant or you're very elderly, if you're above
- 14:1670, or if you have a major medical condition where you know your immune system is shot,
- 14:21then really all of those soft foods are to be avoided.
- 14:25Now the bug we're talking about, Listeria is found in dust and dirt.
- 14:28So is that the one that sometimes goes through air conditioning systems?
- 14:32Yes, Legionella.
- 14:33Legionella.
- 14:34Yes.
- 14:35Listeria will do the same because air conditioning systems suck in dust from the outside, and
- 14:41then we'll blow it in.
- 14:43So sometimes it will blow around, but if we swap these chairs and benches now, we'd
- 14:47find it.
- 14:48It's everywhere.
- 14:49Right.
- 14:50We're just powerful enough not to shrug it off.
- 14:53You're inhaling it all the time when you're breathing in, but one, it's got to get down
- 14:58into your stomach, survive the pH one hydrochloric acid.
- 15:03Then it's got to get into your system, lodge somewhere before it comes out the other end,
- 15:10and then it's got to be in there for a day or two until it starts producing the toxin
- 15:16that makes you sick.
- 15:18But it also has this bug as a particularly sneaky aspect that sometimes it can lodge there,
- 15:25and if you're healthy, it'll stay there.
- 15:27And then if your immune system drops down, it can activate.
- 15:30So there are people who have got food poisoning 70 days after eating the food with this bug
- 15:36in.
- 15:37It's a really unusual bug.
- 15:38It grows at zero, and it'll 70 days after getting eating the food, you can still get
- 15:45food poisoning.
- 15:46It's a really hardy bug, which is not surprising.
- 15:49It's environmental.
- 15:50We know a lot of the bugs that exist in the environment, excuse me, can survive much
- 15:56hard at harsh temperatures because they're sitting out in the dirt.
- 16:00It'll survive freezing, it'll survive for years, it's the super bug.
- 16:06It is a safer.
- 16:07You have to cook it up to higher temperatures to kill it off.
- 16:10It's the highest bug you cook too.
- 16:11So all cooking temperatures are designed.
- 16:13It's the super bug, not in terms of disease, but in terms of survival, it grows inside
- 16:19a vacuum pack.
- 16:20Wow.
- 16:21So it really is most of the systems, most of the cleaning and sanitizing and hygiene procedures
- 16:29that you see in the food industry, even simple things like don't put a box on the ground,
- 16:34wash your hands, cover your street clothes, don't leave a window open, they're designed
- 16:40to stop dust and dirt getting in because this bug is the most dangerous bug.
- 16:45It's a mysterious world.
- 16:47We're just living it.
- 16:48Correct.
- 16:49Yeah.
- 16:50How paranoid should we be about all their conditioning units with old pipes and things?
- 16:55Because this has come up a little bit in like moving around and renting and things like
- 16:58you sort of look at an AC unit and you go, is it okay for me to be blowing that on me
- 17:02or a mind of getting a whole bunch of fungus and stuff?
- 17:07The strict answer is you need to change the filters because they've got filters in and
- 17:12if the filters haven't been changed, yes, you will be everything that's in the filter,
- 17:18turn it all, blow it all over you.
- 17:20So I investigated an outbreak in a major hospital.
- 17:23It was, the stereo was the bug and it was because the filters in the hospital, maintenance
- 17:30thought the contractors were doing it and contractors thought maintenance was, they
- 17:35know one did it and it was decades since the filters had been changed.
- 17:40The actual pipes themselves, the ducts that transmit the air, they don't need to be cleaned
- 17:45because the filter catches whatever.
- 17:47The filters should be catching at all.
- 17:48Is there.
- 17:49They have to.
- 17:50Now, we'll go back to my favorite bag, Listeria.
- 17:52One of the world's first mass outbreaks of Listeria occurred in America in a hotdog factory
- 17:59where there was a faulty air conditioning unit and they removed it during production and
- 18:04all the dust from the parts fell on the hotdog cranks below and 17 people died.
- 18:10Wow.
- 18:11In that outbreak.
- 18:12And if you think hotdog cranks, you think, oh yeah, but they are chilled.
- 18:15It survives chilling.
- 18:16They're vacuum packed.
- 18:18It survives vacuum packing and some people eat hotdogs straight out the pack.
- 18:22They don't cook them.
- 18:23So no cooking steps.
- 18:24So 17 people died in that outbreak.
- 18:26But even if you cook them, it might survive depending on how long you cook them for.
- 18:30If you dip these, you know, most hotdogs you throw into boiling water, boiling water will
- 18:36kill it fairly quickly.
- 18:37Okay.
- 18:38There we go.
- 18:39That's our last stand, our last resistance.
- 18:40What do I always say to people?
- 18:42I tip for buying hot food, you know, and I sometimes travel, you know, where I'm stuck
- 18:46at a roadhouse truck stop at 3 in the morning, nothing.
- 18:50That's where you got pregnant from both of those times.
- 18:53Eating the food.
- 18:56And my tip for anyone who has to eat food, it should be hot enough that you can put it
- 19:01in your mouth straight away and eat it.
- 19:03Hot food should be hot enough that you have to blow on it or let it cool.
- 19:06Right.
- 19:07If you bite into it.
- 19:08It never is.
- 19:09The drumstick that's been sitting in the bakery at the truck stop is tapered.
- 19:14I would hope it's not, but sometimes it is.
- 19:18So my tip is it's meant to be hot enough you can't eat it straight away.
- 19:22Okay.
- 19:23How do we get food poisoning?
- 19:24Because one of the, I think a lot of people think that, well, either it's that the food
- 19:30is off, that it's been around for too long, but oh, I can probably cook it and that'll
- 19:35kill the bugs or that someone who prepared the food, if it's not you, didn't wash their
- 19:40hands after wiping their bum or something and like this fecal matter on it.
- 19:44Yeah.
- 19:45The table will do it.
- 19:46There's also the question of which I hadn't realized until I was taught by you of even if
- 19:52they're, even if the bugs are dead, there are bugs that will have produced poisons that
- 19:59so the food will still be poisoned, even if you do cook it thoroughly.
- 20:03So what is the landscape of how food makes us sick?
- 20:07There's two ways to get sick.
- 20:09One of them is, and the bugs Salmonella, Listeria, you mentioned fecal, that's E. coli,
- 20:16a cherished coli, and there's a few other bugs, Campbell, a bacta is common in chicken.
- 20:20So those bugs you eat the bug and like Listeria, it has to survive getting through your stomach.
- 20:27It then has to lodge somewhere in the gut before you excrete it out the other end.
- 20:33Not anyone listing it lunchtime.
- 20:35And it also has to lodge there and they do produce a toxin, but it takes a couple of days.
- 20:41So the sort of things where you eat the bug and then the bug has to survive in your stomach.
- 20:47They're things that you get sick typically two days after.
- 20:51So I work for one of the big fast food chains and when people say, I bought the product
- 20:57and it tasted off within five minutes I was sick, I just go rubbish.
- 21:01There's just no way you get sick that quickly.
- 21:04It could be something you ate 70 days ago that's caused their problem.
- 21:08So, but you do sometimes, don't you?
- 21:10Is that the other way that you're going to get to or are you saying that in that time?
- 21:13Yeah, there's one we can get quicker.
- 21:14So most, because I had a chimichanga once that I've probably told you about in the past
- 21:18in New York, which is a deep fried burrito, and it's very hard to tell whether it's good
- 21:25or not because it's so full of salt and fat that you know, it tastes good in any way.
- 21:30But halfway through it, I started feeling slightly nauseous and I finished it anyway and
- 21:37then I went away and within 30 minutes I was nauseous and within an hour I was vomiting
- 21:44for eight hours.
- 21:45That would be right.
- 21:47Yeah.
- 21:48And I've never been able to stomach the smell of a chimichanga ever since.
- 21:52So the ones where you eat the bug, that's the different way.
- 21:55So the ones where you eat the bug, it's, you need to eat a lot of the bug or you need
- 22:03to be very young like a baby or very old or very sick or pregnant for it to make you
- 22:08sick.
- 22:09So you're actually...
- 22:10Have you been pregnant?
- 22:11No.
- 22:12And we haven't covered this, haven't we?
- 22:13No, no.
- 22:14Okay.
- 22:15No, no, no, no.
- 22:16Okay.
- 22:17So the, what can happen though?
- 22:18Sometimes, particularly if you eat a lot of food at once, it'll go through your stomach
- 22:24before your stomach can get to it, particularly if it's a really fatty food.
- 22:28So something like peanut butter, chocolate, which basically sits in a blob.
- 22:33There are cases where things have been in things like that.
- 22:35And so if you're a guts and you eat a huge amount of it, deep fried burrito, it's possible
- 22:41that you ate so much your stomach actually pushed it through before the acid got to everything.
- 22:47And a lot of people take things like antacid tablets.
- 22:51So using a brand name, you know, things like gaffer scone and, um, semacase or something.
- 22:57Quickies.
- 22:58Yeah.
- 22:59Quickies.
- 23:00Here also the antacid pills.
- 23:01Yeah.
- 23:02I take those occasionally.
- 23:03Yeah.
- 23:04Those sort of things neutralize your stomach acid.
- 23:06So if you take those, um, you're more likely to get food poisoning because you're actually
- 23:11getting rid of the acid.
- 23:13So if you take one of those before a while eating food, it can also be that the antacid
- 23:19tablet actually neutralizes the acid and the bugs stay.
- 23:23So you're saying that the sticky things like peanut butter and chocolate are more likely
- 23:26to get you sick, not less because they allow the, if bug, the bug can attach to them and
- 23:31bypass the, yeah, if you slip through them, if you think of something, think of something
- 23:36like, I don't know, our falfa sprouts, for example, all little thin things when they
- 23:42get into your stomach, they're going to the acid can easily get to everything.
- 23:47But if it's something fatty and blobby, like cheddar cheese, um, you know, chocolate,
- 23:54peanut butter, not saying chocolate and peanut butter are bad, but they have been issues
- 23:58with some of those.
- 23:59If it sits in a blob, or you, you're just a gut and you eat a lot of food and it gets
- 24:03through your stomach before it's, so there's another reason to eat slowly and to not
- 24:08shovel food into your face.
- 24:09And to chew food like your mum sent to is another reason it's actually scientifically.
- 24:15The more you chew, even the saliva has enzymes in the antimicrobial, so chewing your food
- 24:23and getting saliva all around your food aids digestion and it reduces your chance of food
- 24:28poisoning.
- 24:29Right.
- 24:30Okay.
- 24:31Not just in your mouth, but also then in your gut because the food's in smaller pieces.
- 24:33Correct.
- 24:34The bacteria are more exposed to the pH to the acid.
- 24:38Yes.
- 24:39Okay.
- 24:40So the second group, which is what I think your burrito was in New York, there are three
- 24:44or four bugs that grow in the food and are killed by cooking.
- 24:50However, these four bugs will produce a toxin in the food and the toxins heat stable.
- 24:57So if these bugs grow in the food, they produce a poison, a toxin.
- 25:02And then when you cook it again, you get food poisoning.
- 25:05But because it's a poison, it works much quicker.
- 25:08And so one hour is quick, but one to four hours.
- 25:14And the one you accidentally mention is someone not washing their hands properly, golden staff,
- 25:23which people would know about because it's an infection bug, is carried by about 30% of
- 25:28Australians up their nose.
- 25:31Oh.
- 25:32He says, now I've got me, she knows.
- 25:34Yeah.
- 25:36It's just psychosomatic.
- 25:38So obviously if you sneeze on the food, or if you, you know, the law says you must wash
- 25:44your hands up to touch it, get your body opening, that includes your nose.
- 25:48I'm using a tissue or a handkerchief, then going back to preparing food, scratching
- 25:54a pimple because golden staff is one of the things that causes acne and dermatitis.
- 25:59All of those things in the food industry, you're meant to wash your hands after.
- 26:03And it is one of the things that produces a toxin in the food.
- 26:07Right.
- 26:08But there are three.
- 26:09And that's mild.
- 26:10You're probably, you know, upstairs and downstairs work much better than they meant to
- 26:15for a day or two.
- 26:16But there are three than a last year.
- 26:18There's one called Bissellus Sirius, which is serious as in cereal, of which rice is
- 26:25it's a, that these last three bugs are found in the dirt and rice lives in the dirt.
- 26:31It's in paddy fields.
- 26:32So it's common.
- 26:33And another one called custodian preferringions and one called custodian botulinum, which
- 26:37causes botulism.
- 26:40And those three bugs produce a pretty nasty toxin and they're capable of killing you.
- 26:44Wow.
- 26:45What is botulism?
- 26:46What does it do?
- 26:47Custodian botulinum toxin is the most deadly poison known on earth.
- 26:52It's a biological weapon of war.
- 26:55If you remember way back when Saddam Hussein was saying, why are the UK, you know, why
- 27:01are the weapons inspectors visiting hospitals in universities?
- 27:05We don't make bombs in universities and hospitals.
- 27:09What they're actually checking for was the development of biological weapons of war,
- 27:13like anthrax, but also custodian botulinum.
- 27:16The analogy, if you could get the toxin from custodian botulinum, which would be illegal
- 27:22in Australia, because it's a biological weapon of war, and you extracted that and you dropped
- 27:27it in an eyedropperful into the warrigam, but dam, you would die if you drank from
- 27:33my goodness.
- 27:34Oh, my goodness.
- 27:35Phenomsyniside is warrigam, but dam is where the entire population of greater Sydney gets
- 27:38its water.
- 27:39Oh, better analogy.
- 27:40It's about half a tea cup in Sydney harbour.
- 27:42Right.
- 27:43But to use a different analogy, about half a tea cup, interestingly, the other place in
- 27:48a very, very dilute solution, the what do you think the toxin from botulinum is better
- 27:54known as?
- 27:55What?
- 27:56Botox.
- 27:58So Botox, which is botulinum toxin, is actually, it's a nerve paralysis toxin, right?
- 28:04That's why Nicole Kidman's face card moves, is because she's not the unkind, Gary.
- 28:10Well, she said it.
- 28:11I've actually seen her say, yes, I have used a little Botox, anyway, so this is a deadly
- 28:19poison.
- 28:20That bug, these three bugs grow in food that's meant to be cold or meant to be hot, but
- 28:28is sitting around for a long period of time.
- 28:31So this is the issue in your picnic in the park.
- 28:34And this is our magical two hour, four hour rule, which says no food should be sitting at
- 28:41room temperature for more than four hours, after four hours, you should throw it away.
- 28:45In fact, it says after two hours, you should make a decision.
- 28:49After two hours, you should put it back on the grill and cook it again, or you should
- 28:52put it in the fridge, or if you're at a picnic, shove it back in the eski with the ice and
- 28:57the ice bricks.
- 28:58But if you leave it sitting out for more than two hours, your only option after four hours
- 29:03is to bin it, because these three bugs could have started growing.
- 29:07And these bugs will produce a toxin, and that toxin does have the capability of killing
- 29:14you if you're young or old or sick.
- 29:16That's the range of temperature that constitutes room temperature, because you could be out
- 29:20at a barbecue.
- 29:21Five point one degrees is considered, you know, that's the range, yeah, up to 60, above
- 29:27all below.
- 29:2860.
- 29:29So it's five to 60 is what they call the danger zone.
- 29:32Wait, what?
- 29:33Five degrees Celsius.
- 29:34Five degrees.
- 29:3560 degrees Celsius.
- 29:36Yep.
- 29:37Some of these bugs will start growing.
- 29:38Who's having a picnic where it's 60 degrees Celsius or five degrees Celsius?
- 29:40Five degrees Celsius.
- 29:41That's right.
- 29:42Basically, food should be after two hours, everything from your picnic should be put back
- 29:45in the eski.
- 29:46No, sorry.
- 29:47What I was saying is, because room temperature is the ambiguous thing, when you say I've got
- 29:51four hours to eat at room temperature, if it's a hot, if it's a hot summer's day in Australia,
- 29:57that could be, it could be sitting at 36 degrees Celsius, you know, a hundred Fahrenheit.
- 30:02But if it's in a, you know, if it's in a room and it's winter, it could be 15 degrees
- 30:06or if any of my feelings are listening from state authorities, so they're ready for
- 30:10just switch off for a second.
- 30:12The bugs grow quickest at body temperature.
- 30:15So we're talking 36.37, which is quite hot.
- 30:18Yeah, hot summer's day in Australia.
- 30:22They grow less quickly at 59.9 and 5.1 degrees, but some of them will start growing at those
- 30:30temperatures, so you will get them growing less slowly.
- 30:34So they, they just want one rule.
- 30:36They don't want to say to people, if it's five degrees, you've got six hours, yeah,
- 30:39yeah, yeah.
- 30:40Okay.
- 30:41They just say two hour, four hour.
- 30:42Suffice it to say if it's a burning hot day and you've got some prawns sitting out
- 30:47on the sun, that's different from if it's a cool day and they're indoors in the shade.
- 30:53Yeah.
- 30:54And that, that's used, that two hour thing issues, far more commonly than people think
- 30:58it is.
- 30:59Meals on wheels runs are all less than two hours.
- 31:02If you're on a plane and they serve you on meal, if you don't eat your meal, when they
- 31:07come and collect it, they, they will take it off you.
- 31:10And they will say, if you need something, press a bus and we'll give you another one.
- 31:13Right.
- 31:14They're not being mean when they take, when they take a clear flight too soon.
- 31:17They're like, they're following the two hour rule, but things like hospitals would deliver
- 31:21the ward trolley with all the meals and I'd come back an hour later and pick it up
- 31:24again.
- 31:25Right.
- 31:26So you can't just let it sit there and then pick out it all day.
- 31:28If you ever hire one of those backyard caterers who do spit roasts or wedding parties, you'll
- 31:33find that after four hours, they pack all the food away and they won't give you the left
- 31:37over.
- 31:38So a lot of the industry, a lot of industry uses this rule that if food is going to sit
- 31:43out warm and it does, it buffets, smokers, boards, all of those sort of things, I used to
- 31:49work for that, the, you can say brands here, you're so used to being on the public broadcast
- 31:56where you can't talk about corporations.
- 31:58I used to do work for Sizzler, who's probably the most obvious one for food sitting out
- 32:03because it did the salad bar was their entire huntsuit.
- 32:06Of the Sizzler salad bar.
- 32:07Yeah.
- 32:08It's one of my favorites.
- 32:09Yes, it was.
- 32:10Yes.
- 32:11I still, I've still.
- 32:12Does Sizzler still exist anywhere in Australia?
- 32:14No, it does not.
- 32:15It's taken on.
- 32:16It went under in COVID, pretty much all in the world, but it started up again in the US.
- 32:22I believe Sizzler has reopened in the US.
- 32:25Fabulous.
- 32:26It's worth a trip just to go.
- 32:28So what was the next time I got, I'm going to look, I went to the Bronx to see a traditional
- 32:33old Sizzler when I was in New York.
- 32:35Right.
- 32:36Anyway, we've got to go.
- 32:37So Sizzler, when I work with Sizzler, they actually timed everything.
- 32:41So something's like pineapple is, you know, can sit there or apples are going to sit there
- 32:46all day and never be a problem, but they had timing.
- 32:49So they had a list of all the things on the salad bar and they knew where they went out
- 32:53and when they came back, delivered in 30 minutes or it's free and pizza chains is also the
- 33:00same thing coming in.
- 33:01A lot of the catering industry is set up so everything is done within two hours.
- 33:07Interesting.
- 33:08So it's not just that they're being nice about the 30 minute, it'll be delivered in 30
- 33:11minutes rule.
- 33:12It's that it might be at the pizza hut for 10 minutes before the delivery driver picks
- 33:16it up and you might leave it on your table for half an hour before you eat it.
- 33:20You know, your other thing, it stops a pizza chain, a horrible franchisee making 50 pizzas
- 33:28in advance.
- 33:29Right.
- 33:30Right.
- 33:31Yes.
- 33:32Because they have to be made to order.
- 33:34That's why you can track your pizza in some of the bigger chains.
- 33:37Okay.
- 33:38And just to clarify the two hour four hour rule, we're at my Christmas picnic at the beach
- 33:42park.
- 33:43Does it matter what it is that we're talking about?
- 33:45Because if it's a cooked, you know, if I get say, you know, I've got a roast chicken
- 33:51in the fridge that I cooked from, I cooked yesterday or something like that, versus
- 33:56I go to the supermarket and I grab a hot chicken in the, you know, roasting oven.
- 34:01Yeah.
- 34:02The bachelor's handbag versus I've got some raw chicken that I'm going to grill on the
- 34:08barbecue.
- 34:10Do those behave differently?
- 34:12To some extent.
- 34:13No.
- 34:14Wow.
- 34:15The food that's being cooked has had most of the bunts killed.
- 34:21Really, it, it's only got the three, the three buns we spoke of, a lot of bacillus
- 34:25serious, pastridium botchalone, gastridium profringent.
- 34:30When you cook, you kill the parrot, but they got spores inside like seeds and those spores
- 34:36will survive cooking and one of the things you're done.
- 34:40So if you've got a barbecue chicken and you let it, you put it in the back of your car
- 34:44in the next morning, you think, oh, I had a chicken last night.
- 34:46Where's that gone?
- 34:47So you leave the soup, you get the bologna sauce and leave it on the stovetop overnight.
- 34:52What'll happen is as it cools down overnight, when it gets down to around, in fact, high
- 34:5950s, when it gets to about 50 degrees, those spores are going, oh, hang on.
- 35:04This is okay.
- 35:05And they'll germinate and produce the toxin within about four hours.
- 35:08Right.
- 35:09That's about like 120 degrees Fahrenheit for our American listeners.
- 35:12So hot, but not, but not cooking temperature.
- 35:15And so the, so there, those spores, which are on both the cold chicken that I've brought
- 35:22from home and the hot chicken that I've got from, so well, so all the cold stuff could
- 35:27add everything because of cross contamination, right, because I put it in the fridge as
- 35:31I might have picked up.
- 35:32Yeah.
- 35:33You couldn't, you might not have washed your hands properly, went to the bathroom.
- 35:35You got to eat Carlisle.
- 35:36You mixed up the raw chicken.
- 35:38How dare you imply that?
- 35:39I would never be the kind of person whose daughter would get some in our poisoning.
- 35:43You could have patted your dog and then touched the food, which is why petting zoos often
- 35:48make you sanitize your hands.
- 35:50And in fact, if you've got U.S. listeners, U.S. listeners will know there's actually
- 35:54been major outbreaks in petting zoos in the U.S.
- 35:57Yeah.
- 35:58And so I was actually just at Dubbo Zoo over the weekend.
- 36:01And we did the, you can feed the giraffes with a carrot.
- 36:05And everybody has to use hand sanitizer immediately before that precisely because of zoonotic
- 36:10transmission.
- 36:11Yeah.
- 36:12I think the big, I'll say state fair for the American, this is the Royal East to show
- 36:17in Sydney.
- 36:18They've got a huge farm yard nursery, which you know, you have to queue to get into.
- 36:23I don't know if you're taking your kids there.
- 36:25And afterwards there's, you can't get out of there unless you walk through washing
- 36:29it, sanitizing stations, even kids, even kids who try to walk out, they'll send them back
- 36:34and make them wash their hands.
- 36:35And that's because of what?
- 36:36Eat Carlisle.
- 36:37Eat Carlisle.
- 36:38Eat Carlisle.
- 36:39So it's the, it's the animal poo.
- 36:40It's animal poo.
- 36:41Right.
- 36:42And for your American listeners, they have far more dangerous eat Carlisle than we do.
- 36:47We have relatively safe eat Carlisle here.
- 36:50They'll, you know, they make you, you know, you'll be in the bathroom for a few days,
- 36:54but they've got some really dangerous needs.
- 36:57Is that because they've bred them that way through their agricultural practices or is
- 37:00that just bad luck?
- 37:02Both.
- 37:03You both, they've, they've by mechanizing and farming and getting things, you basically,
- 37:10you concentrate the sort of bugs and microorganisms, you know, if you're farming every animal every
- 37:16same way inside a huge seed, they'll only get the same disease, they're going to have
- 37:20the same bugs.
- 37:21It's much of the same way you and your kids probably have the same bugs inside you because
- 37:25you're in the same household.
- 37:27So eat Carlisle.
- 37:28When, when you eat?
- 37:29So just to pause on that concentrated animal feeding operations, these huge like Midwestern
- 37:33factory farms are conducive to bacteria, and therefore the E. Coli is able to perfect
- 37:41itself to those cattle feed lots will do the same because all the animals are walking
- 37:46in the same poo.
- 37:47Right.
- 37:48So as we're here, we have a more free range agricultural industry because it is less of
- 37:52an incubator.
- 37:53Yeah, it is.
- 37:54Yeah.
- 37:55So isn't it also true that like they sometimes get E. Coli from just eating bagged lettuce
- 37:59and stuff because there'll be some hog farm that was spraying like this hog pig sewage
- 38:05into some river, and then they've used that water to spray the lettuce with and people
- 38:11get E. Coli from salads.
- 38:13Yeah, you can get it.
- 38:14You can get E. Coli from salads that way.
- 38:16We've had manure cause in the E. Coli outbreak here.
- 38:20The major way we had a huge Salmonella outbreak in Australia this year, and it was one
- 38:25of a dangerous strain of Salmonella, a really unusual dangerous strain that has the potential
- 38:31to kill someone.
- 38:33And we pulled all of the pre-prepared lettuce mixes and salad mixes in all the major supermarkets
- 38:40except for Western Australia, which is so far away, it grows its own lettuce.
- 38:45Yeah.
- 38:46Of course, it takes you five days to set the truck.
- 38:50It literally you can't send food from the Eastern States to Western Australia for quarantine
- 38:55reasons.
- 38:56Oh, right.
- 38:57This is a good example.
- 38:58But I mean, even if you wanted to, it's the same distance as going from New York to Los
- 39:01Angeles.
- 39:02You wouldn't want to send a lettuce.
- 39:04Or for anyone in Europe, it's the same, I think, between London and Moscow.
- 39:07Yes.
- 39:08There's a lot of countries to travel through in Europe before you get there.
- 39:11So with lettuce and things like, your major problem is birds and animals poo on them.
- 39:19You know, things like birds have got Salmonella in them, bats, but even things crawling on
- 39:25the ground.
- 39:26You know, like rats and mice and in Australia, kangaroos, you know, things hopping in amongst
- 39:32the fields.
- 39:33You don't have to spray manure on them, like buns on them.
- 39:36Right.
- 39:37And of course, they all got dust and dirt blowing on them, which is listeria.
- 39:40But I assume that before they hit the bag or the shelf that they get drenched in chlorine
- 39:46or something.
- 39:47chlorine is the most common.
- 39:49And they, I've been to the factory that they do, in fact, I've been to quite a few of
- 39:54the factories that do this and they're similar in most places around the world.
- 39:59If you think that an Olympic swimming pool has about 10 parts per million chlorine in it,
- 40:05which these places have about 200 parts per million.
- 40:08Okay.
- 40:09So you walk in there and your eyes water as you walk in.
- 40:14My eyes water in my kids' indoor, you know, swimming pool as well.
- 40:18So if it's 20 times as a potent, yeah.
- 40:21And it's usually put in something like a flume.
- 40:23If you think about the flume ride to the amusement park.
- 40:26So it's sort of like being agitated in, and that gets most of it off.
- 40:31Wait, isn't a flume ride at the, isn't that little log that you sit in that goes trundling
- 40:36a lot of little water passage, yes, imagine that there's a, like a little conveyor belt
- 40:42with all the letters being rained on.
- 40:44Yes, I see.
- 40:45Then it goes in a chlorine bath that's being severely agitated.
- 40:48I see it goes tumbling down.
- 40:50But slightly moving it along.
- 40:51Yeah, right.
- 40:52When it comes out the other end, hopefully it's all washed.
- 40:56But what happened was in Australia, they do quite a lot of tests on this.
- 41:00And one test was positive, meaning a piece of letters, somehow something stuck on it that
- 41:06was not meant to be on there.
- 41:08And that caused a national recall.
- 41:09Wow.
- 41:10Is the chlorine okay to eat?
- 41:12Would it want to wash the letters before I, by the time it gets to you, it's gone.
- 41:17Yeah.
- 41:18Okay.
- 41:19So do you wash bag letters and stuff like that?
- 41:20No.
- 41:21Okay.
- 41:22Good to know.
- 41:23What about your baby cucumbers, your cherry tomatoes, your other produce?
- 41:26Not much.
- 41:27Don't bother washing them.
- 41:28If you want to wash them.
- 41:29And some people have the same argument, not just microbiologically.
- 41:32Some people ask about pesticides and waxes.
- 41:35If you put a smooth skin thing like a tomato, an apple, a cucumber, capsicum, or pepper
- 41:46for Americans, you know, courgette, I suppose, or Eugene using some of the terms of the
- 41:51used around the world, those smooth skinned ones.
- 41:55If you put them on to just running tap water, just cold normal tap water and you give them
- 42:00a scrub with a tea towel, paper towel, you know, I could say, I'm just trying to think
- 42:05of the overseas brand and chucks would be the brand to Australia, one of those semi-disposable
- 42:11wipes.
- 42:12You just give it a good scrub.
- 42:13You get 99% plus of all the chemicals in the bugs off.
- 42:17Yeah, right.
- 42:18What if I choose my thumb?
- 42:19Why do I need a tank?
- 42:20Can I just rub it with my hand?
- 42:21You can.
- 42:22You put it between two hands and give it a good scrub.
- 42:24You get most of them.
- 42:25It's actually easy to get most of this stuff off.
- 42:26Okay.
- 42:27And if you're going to cook, it's really not an issue.
- 42:29If you're going to cook and eat the food hot, no, for pesticides, it might be.
- 42:33Oh, yep.
- 42:34They'll get most of them off.
- 42:35Yeah.
- 42:36But I mean, the cooking isn't going to get rid of this.
- 42:37Cooking might get the pesticides.
- 42:38And so this is all actually a parenthetical tangent to your point that you were trying to
- 42:42make about the cold chicken, the hot chicken, and the raw chicken.
- 42:46So yeah, what's going on back to your real logically?
- 42:49The hot chicken you need to keep hot.
- 42:51Yes.
- 42:52If you don't, the three things that could be in there for the spores, and it's the stuffing
- 42:56mix that we use in Australia, because herbs and spices have a high spork out.
- 43:01So the stuffing is probably more risky than the chicken is.
- 43:05Is that right?
- 43:06Or the seasoning on the outside is probably more risky than the chicken.
- 43:09Because there are essentially bacteria eggs in the herbs.
- 43:13Yes.
- 43:14In the herbs and spices.
- 43:15Right.
- 43:16And the herbs and spices, when you've cooked them, you've killed the parents, but the
- 43:18babies have survived.
- 43:19So if the chicken is set to our warm for more than four hours, some of them will germinate
- 43:23and reduce the toxin.
- 43:24Now, will I make it safer if I cut up the chicken, or not cut up?
- 43:28If I cut up the chicken into quarters, so that there isn't that heat capture in the
- 43:35middle, it is if you put them in the fridge afterwards.
- 43:39So the issue with cold food is it's all the bugs we spoke about plus all the spore
- 43:45formers.
- 43:46So if they're sitting around warm, then you're, they will start growing, okay?
- 43:52But if you've, if you've got a barbecue chicken or large, large hot food, pot of soup,
- 44:00full lasagna, moussaka, you know, those rice, Greek rice puddings, all of those.
- 44:06Anything that could remain hot in the center.
- 44:08Yeah.
- 44:09For a long despite being refrigerator.
- 44:10A pizza kills really quickly because it's a thing, a large pot of spaghetti, bolognese,
- 44:15you know, those sort of things, you've, when you put it in, you either need to,
- 44:21eat it hot, two hour, four hour rule, or if you want to cool it down to stop those spores
- 44:28germinating, you've basically got to get it down under five within four to six hours.
- 44:35Right.
- 44:36And in a commercial fridge, five is like, lower than 40 for American listeners or 38 or
- 44:41something like that, Fahrenheit.
- 44:42Yeah.
- 44:43So like cold, actually genuinely cold, genuinely cold.
- 44:46So when you're taking it down to that temperature, in a commercial refrigeration, like the
- 44:51thing you see at a fast food chain or a restaurant or a manufacturer, it can be one
- 44:57inch or two five centimeters thick, but in a domestic fridge, which doesn't have the
- 45:03pulling power, the commercial, because commercial refrigerations got last fan units in it.
- 45:09In domestic fridge, which are primarily static, it should be no thicker than one inch
- 45:14or two and five centimeters.
- 45:16So you need to portion the lasagna, you need to decant the soup, you need to get the
- 45:21barbecue chicken and portion it, don't leave the KFC in the bucket.
- 45:26You know, for example, an inch is overkill, surely that's being too careful, because a chicken
- 45:30drumstick is more than an inch.
- 45:32I mean, I'm not going to carve the flesh off the drumstick.
- 45:35I can put a drumstick in the fridge, surely.
- 45:37Squash it slightly flat.
- 45:39I don't want no squashed drumstick, Gary.
- 45:42But if anyone who's listening who's a physicist, it's simple thermodynamics.
- 45:46It's heat transfer.
- 45:47Yeah.
- 45:48So basically, can you get the heat out?
- 45:51Drumsticks are good bad example, because the bugs go into the bone, because the bone's hollow.
- 45:57So it actually is the center of the drumstick that is the riskiest part of the drumstick.
- 46:01And it's also the last to cool.
- 46:03It's also the last to cool.
- 46:04It's a last to heat up.
- 46:05Right.
- 46:06Yeah.
- 46:07And it's the last to cool down.
- 46:08Okay.
- 46:09And then the raw chicken that I've got at the barbecue, that presumably is not so much
- 46:14of a worry because I'm just going to cook it anyway, but what about the, I mean, I'm
- 46:17going to cook it through because it's chicken.
- 46:18Well, I'm hoping it didn't sit on the Christmas cake or in the sand, which is because the raw
- 46:23chicken should be kept separate from any ready to eat food.
- 46:27Yeah.
- 46:28But if you put the, if the chicken, that raw chicken can walk onto the barbecue grill,
- 46:31no, it's safe.
- 46:32Yeah.
- 46:33And so four hours, it can sit out.
- 46:35Is that the same rule?
- 46:36And then you're just going to cook it.
- 46:38Yeah.
- 46:39Okay.
- 46:40The one of the other things that would remain warm in the middle, but cold outside, which
- 46:44I know that there's very strong advice about is rice is a bucket of, you know, you might
- 46:48go to Chinese, get Chinese takeaway, you've got a plastic container or you put your fried
- 46:52rice in and you pop it in the fridge.
- 46:56Now every time that you and I have spoken about the subject of rice, you have said it's
- 47:00a deadly killer.
- 47:02And if you don't smear it very narrowly, you know, very thinly one inch, you're going
- 47:09to die.
- 47:10And then whenever we're on the radio, I get in undated with calls from Asian Australians
- 47:15saying, what's this guy talking about?
- 47:17There are a billion Asians who never do that.
- 47:19And I've never been sick.
- 47:21Yeah.
- 47:22Well, one, you can get resistant to straights.
- 47:25So you're probably worse sick at some stage and when you're younger, you know, you're more
- 47:30resistant to those strains.
- 47:33You're right.
- 47:35We used to get lots of Asian people saying, that's the way it's done.
- 47:39In my industry, the silly series is actually colloquially called fried rice bug.
- 47:45It's extremely common.
- 47:47And my state New South Wales, for those who aren't in New South Wales, where we're doing
- 47:53this podcast today, New South Wales is actually a special guideline on sushi.
- 47:58And there's a special guideline on Greek rice pudding for exactly the same reason because
- 48:04rice is so risky.
- 48:06And the issue is that bug basil is serious, which is found in dirt, but rice grows in dirt.
- 48:12So rice, if you do want to cool down rice, and in most Asian cooking, you do cool down
- 48:17rice, you want the surfaces of the grain to dry out.
- 48:21So the next day when you're stir frying it, it's not like, you know, my mother used to
- 48:26cook rice, which was plug, you know, boil the hell out of it until it's pissed.
- 48:30Yeah.
- 48:31You all over it and sticks together.
- 48:32It's a solid lump in proper Asian cooking.
- 48:36You do let the rice cool because you want the surface of the grain to dry out.
- 48:40And then when it's stir fries, it's stir fries easily, rather than becoming a paste.
- 48:45Right.
- 48:46But when you're cooling, you need to cool down now most Chinese restaurants or Asian restaurants
- 48:52will accook serve.
- 48:54So it's not an issue.
- 48:55Yes.
- 48:56They talk people who prepare it in advance.
- 48:58They're using blast chillers to cool this stuff down.
- 49:03And now the blast chiller is the industrial string version.
- 49:06Right.
- 49:07And there they've got a two inch or they can go thicker, they can go longer because pretty
- 49:13much those things will take it from hot.
- 49:15That will take it down under five within two hours, almost no matter how thick it is.
- 49:20Well, these are, these are industrial string fans for us for us.
- 49:24This norm is your point is I order Chinese take out, it comes home, I home delivery,
- 49:30I go on the Uber Eats or whatever, and I only eat one of the two plastic containers
- 49:37of rice.
- 49:38Yeah.
- 49:39And I toss the other one in the fridge, you say, no, no, not with it.
- 49:44Some of those containers are less than an inch, they're the long rectangular ones.
- 49:49No, but I'm thinking like a round one or something or a thick one.
- 49:53No, no, no.
- 49:54If you're using one of those cylindrical ones, decanted, put it into another container.
- 49:59Because in the interior, the Nicole Kidman's face will be gradually, well, let's not,
- 50:04that's not that one, because that one actually takes slightly longer.
- 50:07Oh, isn't that the one you said exists in the dirt that rice grows in?
- 50:11Yes, no, that's a bit serious.
- 50:13That one works quite quickly.
- 50:14And what's what's the Botox one?
- 50:15Kustridium Botulinum.
- 50:16Oh my goodness.
- 50:17It could make them easier names.
- 50:19Okay.
- 50:20Understood.
- 50:21They are not hard compared to, you know, interest-terrified esters of riddle-laying acid in some of
- 50:28the food additives.
- 50:29But the micro organisms are easy to get to the food additives.
- 50:32Okay.
- 50:33And while we're on the question of heating or cooling things in the middle and like the
- 50:37middle being the sort of hazard point that you need to worry about, you're reminding
- 50:41me also of a difference between e-coli poisoning in the United States and outside of the United
- 50:46States because of the way they cook their burgers, which brings us to the barbecue itself.
- 50:51And meat patties.
- 50:53So in the United States, I like the bleeds in the middle.
- 50:57Yes.
- 50:58Unfortunately, I have become a convert to that as well.
- 51:00And it is really, I mean, it's shocking how much distaste I have for Australian burgers
- 51:05now because there's so well cooked all the way through and the patties are so thin.
- 51:09But the word is well cooked, well done.
- 51:14We've never had a food poisoning outbreak in Australia with hamburger patties full-stop.
- 51:20Because that's because it's illegal to serve them anything other than well done.
- 51:23Well, even before they made it illegal, even before that, we've never had an outbreak here.
- 51:27And that's because Australians eat meat well done traditionally.
- 51:31Well, patties.
- 51:32Patties, but not steaks.
- 51:34Oh, we used to eat steak well done too.
- 51:35Well, yeah.
- 51:36I mean, back when we didn't know anything.
- 51:37Yeah.
- 51:38Yeah.
- 51:39Yeah.
- 51:40I'm old.
- 51:41But I mean, yes.
- 51:42It's a very sort of 1950s like English, like cuisine of like, you know, just cook the
- 51:49shit out of everything.
- 51:50Yeah, man.
- 51:51I'm used to boil meat.
- 51:52Yeah.
- 51:53It's horrendous.
- 51:54But I mean, certainly in my lifetime, the understanding that it is unsophisticated from
- 52:01a culinary point of view to eat things well done has become entrenched, but because of
- 52:06the hazards of E. coli, we still do burgers well done.
- 52:11Explain why ground beef is such a unique threat.
- 52:15Well, we're talking mainly hamburger patties are the most obvious, but there are other
- 52:21products out there sausages would fall into this group.
- 52:25If people know what the under showy very country knows what a rissole is, there's basically
- 52:30meatball or funny shape to meatball or a meatball would fall into this category as well.
- 52:35All of those sort of products, when we, if you're, you know, healthy human, pretty much
- 52:40all the bugs are on the outside of you.
- 52:42And to some extent, your gut is the outside of you and your muscles are sterile.
- 52:48And really, it's only when you cut into a muscle and the bug gets into it so that you get
- 52:53an infection.
- 52:54Right.
- 52:55So the same issue.
- 52:56I am the animal being eaten in this analogy, right?
- 52:59So in what happens is when you slaughter an animal and the meat and with the talking whole
- 53:05muscle meat, you know, a lump of meat, all the bugs are on the outside because the actual
- 53:11meat is sterile.
- 53:13And just to clarify, steaks are muscle.
- 53:15Yes.
- 53:16Yeah.
- 53:17Yeah, steaks are whole muscle.
- 53:18So things like cut to people, they cut things like up, sirloins, fillet mignon, the
- 53:25rump without the cap on, if Americans listening, the tri-tip, um, porterhouse, the porterhouse.
- 53:33All of those are one single muscle where something like a chuck steak is made from multiple
- 53:39little muscles.
- 53:40Right.
- 53:41And a scotch fillet.
- 53:42Skotch.
- 53:43Multiple.
- 53:44It's got two, right?
- 53:45This isn't a chuck steak.
- 53:46Or no.
- 53:47As you go up the animal, the changes.
- 53:48Okay.
- 53:49So the porterhouse strip-loin, sirloin is the same steak, which if I got up a demonstrate,
- 53:55which starts.
- 53:56Don't get off the mic.
- 53:57I don't want to see you point out your own, uh, your own sirloin.
- 54:00So you start at the lower back, and as you go up, which is the longest in this door
- 54:05side for, for people who know medical, it's the same muscle in a cow and in a, and, um,
- 54:11the lamb cutlet is also along the system as door side.
- 54:14Wow.
- 54:15Great cut.
- 54:16So as you go up the, and poor clawing is the same one as well.
- 54:19The eye of the bacon is also the longest in this door side.
- 54:23So as you go up, and where is this, this is the lower back of the animal, uh, the, along
- 54:28the spine.
- 54:29Along the spine, but doesn't matter where along the spine, like how far down between
- 54:34the neck and the bum is it, uh, all it changes is it goes up.
- 54:38So it starts down right now near the bum.
- 54:40Yeah.
- 54:41Uh, it's also the big muscle in the t-bone is all of the same thing.
- 54:44Yeah.
- 54:45Right.
- 54:46Okay.
- 54:47And as you go up, eventually when it gets to about the middle of your back, it stops
- 54:50being one muscle and other muscle start coming in.
- 54:53Right.
- 54:54And then in Australia, that's the point at which the, uh, boy, the strip-loin, sirloin,
- 55:00porterhouse, we use all of those becomes the ribeye scotch fillet, which we use different
- 55:07names, depending where you are for that.
- 55:09We use American and British names, and they become more tender and more, or they become
- 55:14more and more muscles.
- 55:15And by the time you're getting up to up near your neck, you're in the chuck section.
- 55:20I see.
- 55:21And in fact, the scotch fillet is made of multiple muscles.
- 55:23Yeah.
- 55:24So what, what you need, and it's synced with fat, which is what makes it, yeah, delicious.
- 55:28So what happens is if you've got whole muscle, all the buds are on the outside.
- 55:33So when you go to restaurant and ask for a blue steak, which is still raw in the centre,
- 55:39they all use one of the whole muscle cuts.
- 55:41They fill them in your porterhouse, they'll use the rump cap that tried tip, one of the,
- 55:47the meat that's a whole muscle.
- 55:50But you wouldn't do that up the other end because the blood can go in between the muscles.
- 55:55And so you've got to cook the whole way through if there's multiple muscles.
- 56:00Okay.
- 56:01But we don't.
- 56:02I mean, I don't eat a scotch fillet.
- 56:05Well, that's you.
- 56:06Well done.
- 56:07That's you.
- 56:08I mean, no one does.
- 56:09Yeah.
- 56:10I mean, unless they're in England in the 1950s.
- 56:11I'm going to give you my advice as a food scientist today, and not argue with you.
- 56:17So when you get a, get the meat and you grind it up, you take the buds from the outside
- 56:25and put them in the middle.
- 56:27So simply the, and then if we're talking beef and lamb or in Australia kangaroo, we're
- 56:33talking E. Coli and we're taking that in the centre.
- 56:37So we get the buds on the outside and by grinding them up, we move them from the outside into
- 56:42the middle.
- 56:43So when we're talking a sausage or a hamburger patty, we've taken the E. Coli by can put
- 56:47in the centre.
- 56:48So to kill that, we need to cook it the whole way through.
- 56:51Got it.
- 56:52One amazing thing that I learned from you is that on those pieces of meat, a single piece
- 56:57of meat where you don't look at it and you can see multiple muscles intersecting.
- 57:01But the, you know, the port house, the ramp, whatever that is.
- 57:04If you've got a single piece of meat, that cannot make you sick.
- 57:07As long as you see the sides of it, no matter how raw it is in the middle.
- 57:13It's still raw.
- 57:14Yeah, because you, you can, you would smell, it would make you get, if it was old enough
- 57:20to be so off that it was going to make you sick, then it would be green and slimy and
- 57:23it would make you gag.
- 57:24I will.
- 57:25I won't warn overseas listeners.
- 57:27This does not apply to pork.
- 57:29Yeah, right.
- 57:30Australia in New Zealand, we don't have those parasitic worms that you get in most of the
- 57:35other countries in Europe and North America.
- 57:38So in Australia, I've never eaten a blue pork steak, but you would eat that would be
- 57:43not nice anyway.
- 57:44I've seen chicken breast fillets ashymi in or chicken in Japan as well.
- 57:49How does that work?
- 57:50Well, I think that breast fillets are whole muscle as well.
- 57:53So a breast fillet is a single muscle.
- 57:55Right.
- 57:56So you should be, I've never seen it in Australia or the US or Europe.
- 58:00You should be able to eat raw chicken breast.
- 58:03Raw chicken.
- 58:04Provided it's seared on the outside, or you can do other things on the outside.
- 58:10So things like wasabi, teriyaki, soy, pickling, marinating.
- 58:15Well, when you do see these more often is in the seafood industry.
- 58:19So the Australian programme, which most listeners know, MasterChef, where they always say,
- 58:24it's not Australian, but it's all over the place here.
- 58:27The version you see around the world, the American one is copying the format of the
- 58:32Australian one.
- 58:33The British one, sorry, British, this is quite dry, where the Australian and American
- 58:38ones are quite strained.
- 58:39Just because I know a thing or two about the television space is a template for the
- 58:46global versions of reality television, we've got the pacing of this as a trip for survivor
- 58:51and a whole bunch of things that were not invented here, but were refined.
- 58:56Yes, here.
- 58:57So when MasterChef, they often say, we want the seed, the salmon fillet.
- 59:01We want the scholar to be translucent in the middle.
- 59:04To me, that means raw in the middle.
- 59:07You just pan sear, so something like a salmon fillet is a whole muscle.
- 59:11You can just cook it on the outside, and inside is going to be safe.
- 59:15And when you were saying wasabi, is that, you know, is part of the Japanese tradition
- 59:19of wasabi and soy sauce in order to presumably just surface pasteurise the inside?
- 59:25Yeah, right.
- 59:26You basically dip it in those sources and it kills the, it washes away some, you chained
- 59:31in the sauce and kills the sauce as well.
- 59:35So you've got to list microbial load on the outside.
- 59:38So you don't, so I think many Americans will think, well, you eat a steak rare.
- 59:43So therefore I should work on a hamburger patty rare, but you've just explained that that's
- 59:47because there is an outside surface all the way through.
- 59:52There are millions, there are, you know, there's a whole multitude of outside surfaces on
- 59:55the inside of the hamburger patty.
- 59:59So why don't more Americans get sick or do they just get sick at much higher rates?
- 1:00:06America, well, America has Ecoli 0157, which is one of the really dangerous strains.
- 1:00:12And this is said earlier, they're farming practices.
- 1:00:15It occurs naturally and they're farming practices have tended to concentrate.
- 1:00:19Does that have interest?
- 1:00:20Why is it not global by now?
- 1:00:21Like with the amount of travel and stuff, how does, how would this, how is Australia
- 1:00:25immune?
- 1:00:26Why wouldn't someone have got got off a plane with some Ecoli under their fingernails
- 1:00:30from having it in the burger?
- 1:00:31Australians will understand this.
- 1:00:32Have you seen the border show on Chaddle Saturday?
- 1:00:35I come and go through the Australian border and met very frequently.
- 1:00:38Look, I know that program showed overseas because I've seen it overseas.
- 1:00:43Australia is pretty, pretty tight quarantine laws.
- 1:00:46And in fact, one of the major political decisions this year was to allow American beef into Australia.
- 1:00:53It's been banned for over 20 years.
- 1:00:55But I just mean I'm at LAX and I order a burger and there's just some on my hands and I don't
- 1:01:02wash my hands.
- 1:01:03I go to sleep on the plane.
- 1:01:04I get off and then I prepare food here or something like I wouldn't, do you need more
- 1:01:09of it?
- 1:01:10Yeah, you need more of it.
- 1:01:11It's likely that everything else you touch between LA and Sydney has rubbed it off again.
- 1:01:16I see.
- 1:01:17If that makes sense.
- 1:01:18Yeah, yeah.
- 1:01:19I think without realizing like, you know, held a hot food and you pasteurized your hands
- 1:01:25and that makes sense.
- 1:01:26Yeah.
- 1:01:27You know, you ate a french fry.
- 1:01:28The french fry would be hot enough to kill where there was on your fingers.
- 1:01:31Okay.
- 1:01:32That sort of stuff.
- 1:01:33Right.
- 1:01:34So anyway, so in America, they've got this horrible E-coli.
- 1:01:36In America, they are allowed to irradiate hamburger meat.
- 1:01:41What's the radiation?
- 1:01:43Put it through gamma irradiation.
- 1:01:45They sterilize it.
- 1:01:46Wow.
- 1:01:47So they're blast radioactive waves at it and it kills the bugs.
- 1:01:52They irradiate it.
- 1:01:53Have you seen how they do this?
- 1:01:55I can't envisage how you do they have big slabs of meat before they mince it or do
- 1:02:01they grind it up and then blast it or something.
- 1:02:04I haven't seen it done.
- 1:02:06Most stuff in the pharmaceutical industry is irradiate.
- 1:02:09When you're going to hospital, the bandages are sterile, the pills are sterile, you know,
- 1:02:15the catheter, the IV bag, virtually everything in a hospital is sterile.
- 1:02:20Yep.
- 1:02:21And in fact, a lot of pharmaceuticals, things like tampons, condoms, you know, some things
- 1:02:26that go into some pretty intimate parts of our body are all gamma irradiated.
- 1:02:31Oh, I just assumed like hospital equipment would have been blasted in a hot steam thing
- 1:02:36or something like boil.
- 1:02:37The big person, a company called Ansel here who you would know in Australia mainly because
- 1:02:42they do rubber gloves and the biggest manufacturer condoms are also the biggest irradiators
- 1:02:48and they run businesses, even though they're known for condoms and rubber gloves.
- 1:02:52Most people know that most of their business is irradiation.
- 1:02:56And so in them, what it is is they put it into a huge chamber wheel, you know, whatever
- 1:03:03it is, a trolley, a pallet in and then zappet and wheel it back out again.
- 1:03:07Okay.
- 1:03:08And so that gets rid of the E. coli.
- 1:03:10So in America, the hamburger meat is pretty much sterile because they're pretty much
- 1:03:16killed everything.
- 1:03:17We're in Australia.
- 1:03:18We still have all the natural E. coli still present in it.
- 1:03:21I do remember during like free trade conversations and around Brexit and like there was there's
- 1:03:27always this talk outside of the United States when negotiating trade deals with the United
- 1:03:33States about, you know, panicked foreigners saying we're going to get chlorinated chicken
- 1:03:39and irradiated beef and like all of these horrible industrial foods that Americans produce
- 1:03:44and consume.
- 1:03:46Is there, so it sounds like there is something to that, even if the irradiation is benign.
- 1:03:53It's unless you're a cat, we'll go there and you'll see there is, there is a minor change
- 1:03:59in some of the chemical structure which apparently has an effect on cats.
- 1:04:02So irradiate cat food out of America can't be irradiated.
- 1:04:06Okay.
- 1:04:07There's a note.
- 1:04:08Okay, interesting.
- 1:04:09We've had a discussion in one of the segments we used to do together on difference with human
- 1:04:13food and pet food.
- 1:04:14Oh, yeah.
- 1:04:15Yeah.
- 1:04:16Yeah.
- 1:04:17Pet food stand.
- 1:04:18It's a harder industry than human food stand.
- 1:04:20Wait, they're higher.
- 1:04:22The pets are eating better food or less contaminated food.
- 1:04:27The raw material is more contaminated.
- 1:04:30In the sense of cats really don't care if it's got eyes and bones in it.
- 1:04:34Yeah.
- 1:04:35Okay.
- 1:04:36The reasons of the standards, at least in this country, most of the pet food manufacturer
- 1:04:42also meet facilities.
- 1:04:45So they're registered as meet facilities, which is a higher level than local inspection.
- 1:04:51They are also, most of them supplied the major supermarkets.
- 1:04:54So they have to meet these standards for supermarkets.
- 1:04:59And they also have to meet veterinary standards because they're into the animal industry.
- 1:05:05On top of that, most of the big manufacturers, except for foreign objects like eyes and
- 1:05:10bones and heads, most of the manufacturers here in terms of chemical residues and microbiology,
- 1:05:17the food is made to human food standards because they know the kids crawl across the floor
- 1:05:21and eat out the dog bowl.
- 1:05:23Oh, my goodness.
- 1:05:24So I could easily eat any pet food.
- 1:05:27If it's a well-known brand name from a major supermarket and it's not raw meat, yes,
- 1:05:33all those canned dog food, all that kibble, all the dog treats, your cat treats, you know,
- 1:05:41you could eat dogs.
- 1:05:42I know what I'm doing this Christmas.
- 1:05:43You could eat those all.
- 1:05:45So if your kids accidentally eat the dog kibble, yeah, that's all right.
- 1:05:49Yeah, it's all right.
- 1:05:50In fact, I've done that taste test.
- 1:05:51Have you?
- 1:05:52Yeah, I've been, I've been inspected Mars, I'm hoping you use brand names can't be.
- 1:05:56So for Australians and some of these brands are international because they're owned by Mars
- 1:05:59Peck Care, who's an international brand.
- 1:06:02So I've eaten whiskets, good O, meaty bites, schmackos and denta bone.
- 1:06:11I've eaten all of those as part of a quality assurance test at a pet food company, avoided
- 1:06:17the taste testing at the canned dog food factory.
- 1:06:21What's a schmack I like?
- 1:06:23It's not good.
- 1:06:26Meaning it tastes a bit, it tastes like a soft, if anyone you've had a salmon jerky,
- 1:06:31it tastes like a soft, like a, it's like a, I'm just trying to think it's, it's not like
- 1:06:37a jerky like a hard thing.
- 1:06:39It's like a baked mince, but it tastes really odd.
- 1:06:44And I know why it's all because they spray hydrolyzed awful, they spray rotten awful on
- 1:06:48the outside.
- 1:06:49Because dogs like that.
- 1:06:50Dogs love the taste and smell of it.
- 1:06:52Oh, wow.
- 1:06:54Isn't there a better way for the pet company to do a quality assurance test than to feed
- 1:06:58it to you?
- 1:06:59No, they say it's actually the best way, because if you eat it every day, you pick up.
- 1:07:03And you know, we're not just talking, they're talking textural, you know, some pets are
- 1:07:08fussy.
- 1:07:09Right.
- 1:07:10Yes.
- 1:07:11But how do you know what they're fussy about?
- 1:07:12Well, they do taste panels in Australia, guide dogs and police dogs.
- 1:07:21The German shepherds that he used for police dogs and the Labrador's that he used for
- 1:07:25the guide dogs in Australia, they often get free food.
- 1:07:29Wow.
- 1:07:30And they do that because they send you formulations or new recipes and they actually see if the
- 1:07:34dogs are leotered or not.
- 1:07:35Hmm.
- 1:07:36Hmm.
- 1:07:37There you go.
- 1:07:38Now we were also talking before we went to air about the way that the foods that we eat
- 1:07:44affect our behavior, our smells, our, you know, what we smell like and so on.
- 1:07:49So at a time of year when we change our diets quite a lot and we may be over and dulled,
- 1:07:55should we just start with the question of, um, I mean, this is more of a Thanksgiving
- 1:07:59question than a Christmas question, but often we have turkey at Christmas as well.
- 1:08:02Trip to fan is an urban legend, right?
- 1:08:04I mean, it's not, we don't consume it in turkey and high enough doses to make us
- 1:08:09try it.
- 1:08:10Trip to fans and essential amino acid, you're, um, yet you need it to make proteins.
- 1:08:16Right.
- 1:08:17And we don't assume it didn't end up to the reason we get tired after a big Christmas
- 1:08:21lunch is because we've eaten a lot of what fat and we need to digest it or something.
- 1:08:25Yeah.
- 1:08:26What what happens is when you eat a big meal, your body goes, Oh, I've got a digested
- 1:08:30big meal.
- 1:08:31So it switches off non essential functions.
- 1:08:34Right.
- 1:08:35Um, same reason when you drink a lot of alcohol, your body goes, Oh my god, someone's
- 1:08:40taking it a poisonous toxin, I need to deal with that.
- 1:08:44And it'll shut off your system.
- 1:08:46So you feel tired because it doesn't want you to exercise.
- 1:08:49It would prefer if you went to sleep, so you prefer if you went to sleep because then
- 1:08:53you stop doing everything and your body can concentrate on getting rid of the food.
- 1:08:57If it's the turkey or the alcohol, yeah, if it's that because you know, alcohol to
- 1:09:03your body is a toxin.
- 1:09:05Yes.
- 1:09:06So it wants to do it.
- 1:09:07So that's why you feel tired.
- 1:09:08It shuts you down.
- 1:09:09And so and then the other impacts on the body.
- 1:09:11So the types of foods that we eat, do I smell different after eating certain foods?
- 1:09:16Yeah, you do.
- 1:09:17Oh, yeah, you do.
- 1:09:18And the really obvious one that everyone picks up is garlic and onion, which all, you
- 1:09:25know, it goes into your bloodstream.
- 1:09:28It goes into basically all your lymphatic system.
- 1:09:32So it'll come out in the breath in your lungs, you know, breath certainly, but it doesn't
- 1:09:37come out in my sweat.
- 1:09:38It does.
- 1:09:39It'll come out in your sweat, so your sweat garlic, your sweat onions.
- 1:09:46And when you were talking about alcohol, what about alcohol?
- 1:09:48There's a smell of someone who has had a big bender.
- 1:09:53And even if they haven't drunk for a while, so it's not alcohol coming off their mouth.
- 1:09:58There's a distinctive smell of like, oh, wow, you're coming in steaming.
- 1:10:01Yeah, it's your, it's not the alcohol itself.
- 1:10:05It's the byproducts of it coming out.
- 1:10:09So it's the things you don't normally smell.
- 1:10:12It's also if you're alcoholic, your body systems aren't working as well.
- 1:10:19So they don't get rid of things as efficiently as they used to because your body is starting
- 1:10:25to shut down.
- 1:10:26Right.
- 1:10:27And that's in a very severe case, presumably, so people who are chronic alcoholics do have
- 1:10:32smells about them, which is to do with the fact that your body is not as good at getting
- 1:10:37rid of the smells.
- 1:10:38Two things like through the liver, so instead of, it's floating, your liver and kidneys
- 1:10:43aren't pulling it out.
- 1:10:44So it's floating around in your system, and it's coming out in your sweat in your breath
- 1:10:49more often.
- 1:10:50Okay.
- 1:10:51So alcohol, garlic, onion, what else meat?
- 1:10:53You eat a whole meat diet, you start getting meaty byproducts, smells.
- 1:11:00What happens to your gut?
- 1:11:01Well, there's this whole universe of people who are on, like, carnivore diet, right?
- 1:11:06The keto diet is a great thing.
- 1:11:08So there's keto, but keto can still have quite a lot of fruit and veg, right?
- 1:11:12Yeah.
- 1:11:13I'm talking about actual carnivore, like Jordan Peterson and, like, some health people
- 1:11:16are, like, have a very strict, like, I only eat meat, but do they ever poo?
- 1:11:22The right one.
- 1:11:23The right one.
- 1:11:24The right one.
- 1:11:25The right one.
- 1:11:26The right one.
- 1:11:27So is that, like, what do you make of that?
- 1:11:30Constipation could be an issue, but I don't understand.
- 1:11:34Are they having a lot of psyllium husks every day to keep them regular?
- 1:11:38I'm not being on that diet, but I'm hoping there's something that's getting them going,
- 1:11:42because if not, oh, that's a diet that certainly linked to colobic and rectal cancer, heart
- 1:11:49disease, diabetes.
- 1:11:50I mean, if you're going to go on any extreme diet, and I'll say just eating meters in extreme
- 1:11:58diet, you've got to talk with a dietitian or nutritionist about what's going to happen.
- 1:12:03I mean, but they're people who are skeptical of conventional dietary advice.
- 1:12:09With some reason, I mean, you know, we're keeping told that, like, I don't know, fat's
- 1:12:13terrible and that sugar's okay and that, you know, carbohydrates are great.
- 1:12:17And we did our nutrition lectures at uni and part of food science degree is human nutrition.
- 1:12:21It's not a huge part of our degree, but it's there.
- 1:12:24And we're taught as part of that that every 20 years, something new comes in and disagrees
- 1:12:32with something was, you know, eggs were bad, they're eggs are good.
- 1:12:35Yeah.
- 1:12:36We completely bungled it on cholesterol.
- 1:12:38Yeah.
- 1:12:39Meat was bad.
- 1:12:40Then, oh, no.
- 1:12:41Now we have our nine deficiency.
- 1:12:42Now meat is good.
- 1:12:43Now only some meat is good.
- 1:12:44Yeah.
- 1:12:45Yeah.
- 1:12:46Carbs were out.
- 1:12:47Yeah.
- 1:12:48Now some carbs are back in again.
- 1:12:49Yeah.
- 1:12:50Yeah.
- 1:12:51It changes.
- 1:12:52Unfortunately, can I say of all the food injuries, the thing that's most frustrating because
- 1:12:57there's no clear message and the older you get, the more the messages are mixed, particularly
- 1:13:03when you, with the internet where you get, it's easy to find any weird diet you want.
- 1:13:11Yeah.
- 1:13:12And to find an authoritative looking person in a white lab coat who's doing YouTube videos
- 1:13:16about it.
- 1:13:17Yeah.
- 1:13:18Yeah.
- 1:13:19Yeah.
- 1:13:20Yeah.
- 1:13:21I know that I do much television, but, you know, I'm the TV I do where they say, oh,
- 1:13:23can you wear your lab coat?
- 1:13:24Because, because all sides, because all sides is always doing lab work.
- 1:13:29And we always, it's like every journalist wears a fedora with a press in there.
- 1:13:34Yeah.
- 1:13:35You should, you should say that.
- 1:13:36Do you say that to them?
- 1:13:37Yeah.
- 1:13:38I'll wear it if you put on a fedora hat with a little press.
- 1:13:41I said, I said before we started this, I'm actually filming tomorrow for something for
- 1:13:46the organization where for, yeah, for the ABC, the TV thing, I'll be filming TV and never
- 1:13:52asked that I wear my white lab coat or scientists wear white lab coat.
- 1:13:56Exhausting.
- 1:13:57So what other things?
- 1:13:58We know, obviously people will think when we're thinking about smells asparagus, asparagus
- 1:14:03comes up.
- 1:14:04Yes.
- 1:14:05It's the pain in my life because I love asparagus.
- 1:14:07I eat it all the time and I do not like the smell of my wee afterwards.
- 1:14:11We'll see, there's not everyone, for those who don't know, there's a, let's say there's
- 1:14:16a strong distinct smell.
- 1:14:19Some people produce that chemical.
- 1:14:22Some people don't and some people can smell it and some people don't.
- 1:14:28So there are four quadrants.
- 1:14:30There are four quadrants.
- 1:14:31There's can produce but can't smell, can produce and can smell, can't produce but can
- 1:14:35smell, can't produce and can't smell.
- 1:14:38Yes.
- 1:14:39So you fall into the, I can produce and I can smell, I can't smell it.
- 1:14:45So I'm not sure which quadrants I be.
- 1:14:48Oh, it's all over you, you'll be fine.
- 1:14:50This is great.
- 1:14:52And vice versa.
- 1:14:53I have no idea.
- 1:14:55You would know.
- 1:14:56How would you know?
- 1:14:57I don't know.
- 1:14:58Right.
- 1:14:59Okay.
- 1:15:00And there are other things that change the smell of your urine or like I was even thinking
- 1:15:04about the, if you're a cannibal, would these things that are changing the smell of our
- 1:15:11breath and our sweat and our we change the taste of my flesh if someone ate me?
- 1:15:17Yes, yes, it does.
- 1:15:20You said that a little too definitively.
- 1:15:22You haven't only eaten schmackos, have you?
- 1:15:25No, no.
- 1:15:26Look, for people who know geography, Papua New Guinea is just north of Australia, they've
- 1:15:32actually interviewed cannibals and they've asked these questions of cannibals.
- 1:15:38I think it's our closest neighbor, actually, this is a good pub trivia question for like
- 1:15:42what is Australia?
- 1:15:43Where's the closest country to Australia?
- 1:15:45Because I think everyone says, everyone outside Australia says New Zealand.
- 1:15:48Yes.
- 1:15:49A lot of Australians were saying in Indonesia.
- 1:15:50Yes, I think it's the country.
- 1:15:52And unless you get asked it in WA, because if you ask what's the closest country to Western
- 1:15:56Australia, it's Timor less day.
- 1:15:58Is that right?
- 1:15:59Yes, it's closer than Papua New Guinea.
- 1:16:01There we go.
- 1:16:02Here we go.
- 1:16:03There's a trivia.
- 1:16:04Good trivia, yes.
- 1:16:05I run trivia.
- 1:16:06No, it's as you know.
- 1:16:07Oh, yes.
- 1:16:08That's right.
- 1:16:09A little bit about that.
- 1:16:10Yes.
- 1:16:11So I've asked those sort of tricky questions.
- 1:16:12Great.
- 1:16:13So when you talk to the cannibal.
- 1:16:14So think like a cow.
- 1:16:16So when you talk, when you get white veal, white veal is usually a cow that hasn't been born
- 1:16:24yet.
- 1:16:25No, that hasn't been weaned off its mother's milk.
- 1:16:28No, no, no.
- 1:16:29That's one before that.
- 1:16:30Right.
- 1:16:31You're eating a fetus?
- 1:16:32Yes.
- 1:16:33Yes.
- 1:16:34Yeah.
- 1:16:35Well, it's late term.
- 1:16:36So you slaughter the pregnant cow.
- 1:16:38Yeah.
- 1:16:39And you, the cow goes through the system.
- 1:16:40I couldn't be.
- 1:16:41So that's a fact.
- 1:16:42I mean, that is what a fetus is, right?
- 1:16:43Yeah.
- 1:16:44Yeah.
- 1:16:45Yeah.
- 1:16:46That product is available.
- 1:16:47You can buy that.
- 1:16:48In Australia?
- 1:16:49Yeah.
- 1:16:50Really expensive, not surprisingly.
- 1:16:51Yeah.
- 1:16:52Then you've got veal, which is usually not been weaned.
- 1:16:56Then you've got yelling.
- 1:16:58And then as you get older, your meat gets darker.
- 1:17:02Yep.
- 1:17:03It gets yellower.
- 1:17:06It becomes tougher, the older you get.
- 1:17:10So this is true across almost every animal.
- 1:17:13So an old person will taste tough, they'll be, they'll be gaining because a lot of the chemicals
- 1:17:19that you eat in your diet, you don't lose all of them, some of them accumulate.
- 1:17:25So the meat gets more similar between grass fed and grain fed, you know, you lose some
- 1:17:33of them.
- 1:17:34And often if you're doing feed lotting, what you do is you, you have grass fed cattle.
- 1:17:39And then you bring them into a feed lot.
- 1:17:41And for 90 days, you feed them very bland cereal.
- 1:17:44And you get rid of most of the, the taste, but some still remains, but some, because most
- 1:17:49consumers don't like the taste of grass fed, they want the bland.
- 1:17:53In America.
- 1:17:54Meat that taste of nothing.
- 1:17:55America in Japan, absolutely bland as possible.
- 1:17:59Australia, it's about 50, 50.
- 1:18:02What in terms of what we consume or in terms of what we like.
- 1:18:04What we like.
- 1:18:05Right.
- 1:18:06There's 50% of people like beef to be beefy, to actually taste like beef.
- 1:18:11And that's grass fed.
- 1:18:12And that's grass fed.
- 1:18:13That's grass fed stuff.
- 1:18:14And there's another 50% who are unsophisticated, like the Americans and the Japanese.
- 1:18:19We just like it to be a neutral protein.
- 1:18:22And it surprises me about Japan though, I've had incredible steaks in Japan.
- 1:18:26Were they...
- 1:18:27Yeah, but they're wagyu.
- 1:18:28And wagyu is to be bland.
- 1:18:30Right.
- 1:18:31So it's more that they're fatty and unctuous than flavoursome.
- 1:18:35Correct.
- 1:18:36Yeah.
- 1:18:37The fats carrying extra flavour.
- 1:18:38Right.
- 1:18:39Right.
- 1:18:40Okay.
- 1:18:41That's interesting.
- 1:18:42So yes, if the grass can make its way into the flavour of the flesh, then presumably
- 1:18:45all of the other stuff that I'm eating.
- 1:18:46So we should get older, I'm older than you.
- 1:18:49So if we use that analogy, my meat is probably darker, it's probably tougher, it's probably
- 1:18:54gamia, because of all the things that have happened in my life.
- 1:18:58And so cannibals have said that that's true in humans.
- 1:19:01And humans taste like pork apparently.
- 1:19:03Yes, I've heard that, but I mean that also stands for reason because physiologically
- 1:19:07we're quite close to pigs, the meat is the same colour as pigs, the muscle, it sort
- 1:19:13of behaves the same way.
- 1:19:15It's the same sort of, it's not white, it's not dark like a cow.
- 1:19:19Yes.
- 1:19:20Yeah.
- 1:19:21Yeah.
- 1:19:22Why is gamia meat gamie?
- 1:19:22It's the chemicals from the grasses and pastures.
- 1:19:27So it is a dietary thing rather than inace.
- 1:19:29Like if a kangaroo or a deer had the same diet as a cow, would it taste less gamie or?
- 1:19:34No, no, no.
- 1:19:35Different species taste different.
- 1:19:36Kangaroos, a darker meat.
- 1:19:38Yeah.
- 1:19:39But it knows what I mean.
- 1:19:40Like when we took, when we think about the gamemeaks flavour, the medicines, probably
- 1:19:43the most common gamete that's eaten around the world.
- 1:19:47When venison is quite a dark gamemeat naturally, lamb in most countries is considered gamie.
- 1:19:53Really?
- 1:19:54You know, if you're British or Australian or New Zealand where lamb is extremely common,
- 1:20:01we don't consider that to be a gamemeat, but in America lambs can sit by.
- 1:20:06Many people is considered to gamemeat.
- 1:20:08Right.
- 1:20:09Yes, it's very rare.
- 1:20:10Lamb's not popular to hear.
- 1:20:11Yeah.
- 1:20:12We're in Australia in New Zealand, you know, lamb's standard.
- 1:20:14In fact, lamb roast is a fairly standard Christmas roast.
- 1:20:17Yeah, indeed.
- 1:20:18Okay.
- 1:20:19Let's end by thinking about Christmas.
- 1:20:20Is there anything else at Christmas time that is not the picnic or the barbecue that
- 1:20:26we should be aware of?
- 1:20:28Yeah.
- 1:20:29A couple of things.
- 1:20:31One of them is done by so much you can't put it in the fridge.
- 1:20:35Yes.
- 1:20:36Right.
- 1:20:37Your other one is how soon can the left over is two hour or four hour rule.
- 1:20:43The toxins we spoke about can affect the pets as well.
- 1:20:47So cats and dogs can also get sick from those toxins.
- 1:20:51So if you think, oh, in search, rude word here, I've left the food out for six hours.
- 1:20:57Oh, well, give it to the dog.
- 1:20:59I'll give it to the dog.
- 1:21:00The dog can get sick from this as well.
- 1:21:02And dogs don't need as much to get sick because they're much smaller.
- 1:21:05So a smaller amount of food will make it's wider, but why do we think the dogs won't
- 1:21:10be like dogs just seem to eat, I mean, everything, they eat poo, they, like, you know, trash.
- 1:21:17Yeah.
- 1:21:18That's because in you, you've got a small intestine and you know, that does the loop, the loop
- 1:21:24and it takes, you know, typically a day, but a dog eats something and, you know, pretty
- 1:21:29soon it's out the other end.
- 1:21:31Okay.
- 1:21:32So the dog's intestinal track smaller, it doesn't stay in there as long.
- 1:21:35So the bugs don't get a good enough chance to lodge and get through.
- 1:21:38Right.
- 1:21:39So it is more resilient.
- 1:21:41And dogs have also built up a resistance.
- 1:21:43Dogs are used to eating poo and dead bird.
- 1:21:46So they've eaten more strains than you have.
- 1:21:49Yeah.
- 1:21:50But young puppies, if you've ever had a puppy, puppies will often eat stuff and throw
- 1:21:54up and get diarrhea.
- 1:21:55Totally.
- 1:21:56They're poor.
- 1:21:57Yeah, poor.
- 1:21:58I'm the person.
- 1:21:59And a lot of that is them getting used to their buds.
- 1:22:01It's why mothers will often lick them to get the buds from the mum into the baby.
- 1:22:06Yeah.
- 1:22:07Well, it's all of that is to build up all the strains and then they can, you know, eat
- 1:22:10squash black stuff on the road like my dog does.
- 1:22:13But it's also partly that it's partly they have got more bugs than we have that they
- 1:22:19used to.
- 1:22:20It's also their intestinal tracks much smaller.
- 1:22:22So it goes through much quicker.
- 1:22:24And so it gets pooed out the other end before it gets your chance to lodge and produce
- 1:22:27the toxins.
- 1:22:28There you go.
- 1:22:29Okay.
- 1:22:30Oh, the last thing that I forgot to ask you about that would be a great note to end on.
- 1:22:34Yeah.
- 1:22:35It's a more pleasant perhaps street food.
- 1:22:36You briefly mentioned that it should be hot like if you go into a roadside diner or something
- 1:22:40or you go to takeaway places, it should be so hot that it's not pleasant, you know,
- 1:22:44you can't just bite straight into it.
- 1:22:46What about when you're traveling and a lot of Australians at this time of year will be,
- 1:22:51you know, going away?
- 1:22:53We like to go to Asia.
- 1:22:54I was on a stop over recently and passing along a street in Bangkok, China town where
- 1:23:01the cornucopia of incredible, delicious and also horrifying things that I could eat.
- 1:23:06I eat these for those stalls as well.
- 1:23:08Yeah.
- 1:23:09By what measure do you determine whether I'm like you go to one stall or another?
- 1:23:12Like are there rules of thumb about being careful about stuff?
- 1:23:15I can.
- 1:23:16If it's a pain, Marie, um, no, I'm mostly talking about hawker stuff, but yes, could
- 1:23:21tell us anyway.
- 1:23:22A good tip for a pain, Marie, once you, you should be able to put your hand down the bottom
- 1:23:27of the glass.
- 1:23:28If you rest it down at the bottom of the glass and you can hold your hand there, the foods
- 1:23:33do cold.
- 1:23:34Okay.
- 1:23:35It should be hot enough.
- 1:23:36You have to pull your hand away.
- 1:23:37Okay.
- 1:23:38I mean, leave it there for a sec.
- 1:23:39Don't burn your hand.
- 1:23:40Yeah.
- 1:23:41But it should be hot enough.
- 1:23:42You can't comfortably wrist your head there.
- 1:23:43And you want to put your hand away.
- 1:23:44Right.
- 1:23:45And so we go with things like this.
- 1:23:46Good old Australian pie warmer would be the same way you shouldn't be a, that's why
- 1:23:50they've got handles on.
- 1:23:51You shouldn't have to push and be able to hold the glass.
- 1:23:53Shouldn't be able to hold on the glass of one of those pie warmers, um, same as a suit
- 1:23:58to reach.
- 1:23:59You shouldn't be able to put your hand and hold your hand comfortably on the side of
- 1:24:02a suit to reach.
- 1:24:03Yes.
- 1:24:04Right.
- 1:24:05When it comes to street hawkers, it is a bit of, uh, have a look at it and I'll hang
- 1:24:12around.
- 1:24:13I mean, remember the marinated duck Maryland in Shanghai.
- 1:24:18There was cooked on them.
- 1:24:19Oh, she was once a foosball machine, you know, you know, good little sticks with, with
- 1:24:24curls in the bottom.
- 1:24:25I, I was sneaking off.
- 1:24:27I watched someone else eat one and looked when they beat into it to see if it was pink
- 1:24:30in the middle before.
- 1:24:31Yeah.
- 1:24:32Right.
- 1:24:33I mean, I, I guess you're also just trusting that the locals know where to go because
- 1:24:37if there is, like if there are cooked meats, for example, hanging above, uh, uh, uh,
- 1:24:42caught above calls and they're pre cooked and their room temperature, that's silly.
- 1:24:46That silly analogy of go where the locals go is actually not a bad tip because the locals
- 1:24:52are not going to go so we have to give you food poisoning.
- 1:24:55Yeah.
- 1:24:56So when I go overseas and I travel in Asia for work quite regularly, um, the two tips
- 1:25:02are one is go where there's lots of locals because the locals know that that place is
- 1:25:09okay.
- 1:25:10The other one, if worse comes to us, aren't the big fast food chains and not that I'm
- 1:25:14recommending that.
- 1:25:15But if Gary, I'm going to pretend you never said that, uh, they're not going to KFC
- 1:25:20in Bangkok.
- 1:25:22If I've been in, I've been in places where it's either dodgy food or the McDonald's or
- 1:25:28the KFC and I thought as much as, and I work out to call complete inches, I've done
- 1:25:32work for both those organizations.
- 1:25:35If I'm in the town, I think, hmm, I need to travel on a 24 hour plane trip.
- 1:25:40What will I eat?
- 1:25:41I'll go eat when the fast food chain because at least then I'd rather not eat.
- 1:25:44It's going to be criminal.
- 1:25:45And I don't say that I wouldn't eat KFC out of snobbery or because I don't like KFC
- 1:25:49just because there's so many better things to eat.
- 1:25:51Yes.
- 1:25:52In Asia.
- 1:25:53If I'm vegetable in a major plane trip, you know, I've, I've got food poisoning a couple
- 1:25:57of times overseas.
- 1:25:58I've got dysentery and Pakistan.
- 1:25:59Oh my goodness.
- 1:26:00I lost, I lost five kilos in a day.
- 1:26:03Wow.
- 1:26:04Um, I've, I've had food poisoning in, in a bay route.
- 1:26:08I've had food poisoning.
- 1:26:09I did this for a living.
- 1:26:10Yeah.
- 1:26:11And I know what I'm doing.
- 1:26:12And I get it.
- 1:26:14Yeah.
- 1:26:15But basically, I look at where they're good tip is eat where the locals are.
- 1:26:19Yes.
- 1:26:20Because the locals are not going to keep going back to a place.
- 1:26:23Oh, I'm going to eat.
- 1:26:24A bit hard with a hawker who might move from place to place, but at least in my travels,
- 1:26:29the same hawkers tend to be in the same place day after day.
- 1:26:32Yeah, exactly.
- 1:26:33Uh, I would still eat at the hawker and if I get the runs and I have a 24 hour plane
- 1:26:37trip, just take some a modium and plug it up, plug it up, carry.
- 1:26:41Yeah.
- 1:26:42It doesn't always work that way.
- 1:26:44Okay.
- 1:26:45On that beautiful note of the, of the, the, the diarrhea still seeping out in spite of
- 1:26:53the pharmaceuticals, Gary Merry Christmas, Happy New Year.
- 1:26:56Thanks for joining us.
- 1:26:57Don't probably be.
- 1:26:58And Merry Christmas to everybody out there.
