Or speed of toddler. We have cascading rules in our house: anything that hits the floor is his within three seconds or else it defaults to daddy, who has the remaining two seconds before the dog makes his move.
Dinner-time incidents can turn violent quite quickly...
Common knowledge is: if food falls on the floor and survives the impact you pick it up quickly, wash it, it's ok. If you find it after hours you trash it.
I don't understand how someone can think this is true. Like, what, you drop your toast with jam on the floor, pick it up in a second, the jam is full of hairs/dust/debris and you figure it's fine?
No, no one thinks that way with regards to any kind of food item with stickiness and the 5 second rule.
The thought revolves around dry foods and the (mistaken) impression they're unlikely to accumulate any kind of debris and dust. Peanuts, pretzels, etc.
That's my impression too. You explain the rule to children, so they can pick up peanuts they drop on the floor, but don't go eating peanuts they find dropped by other people a long time ago.
Do you have children? "Explaining they shouldn't do X" and "the child don't do X" are, ah, much less correlated than you might like. At times they can be downright reverse correlated.
The way I see it, if they're too small, you need to watch them anyway, or else they will put everything on their mouth, not just dropped food.
If they are over that, they're smart enough to understand that they don't eat jelly sandwitch off of the floor, or something they dropped in a public street. But for a casual hard food stuff they dropped on the kitchen floor or living room etc, they can sweep it and eat it -- and get some germ resistance too.
E.g.:
Just as a baby's brain needs stimulation, input, and interaction to develop normally, the young immune system is strengthened by exposure to everyday germs so that it can learn, adapt, and regulate itself, notes Thom McDade, PhD, associate professor and director of the Laboratory for Human Biology Research at Northwestern University.
Exactly which germs seem to do the trick hasn't yet been confirmed. But new research offers clues.
In a recent study, McDade's team found that children who were exposed to more animal feces and had more cases of diarrhea before age 2 had less incidence of inflammation in the body as they grew into adulthood.
Inflammation has been linked to many chronic adulthood illnesses, such as heart disease, diabetes, and Alzheimer's.
"We're moving beyond this idea that the immune system is just involved in allergies, autoimmune diseases, and asthma to think about its role in inflammation and other degenerative diseases," McDade says. "Microbial exposures early in life may be important… to keep inflammation in check in adulthood." (WebMD)
Society. Kids that are raised outside of what is considered the acceptable social norm often have problems adjusting when they get older. For example I actively try to avoid eating out at restaurants with people who are too fussy about their food. It's usually an awkward uncomfortable scene. I'd much rather share a meal with a '5 second rule' type of person.
It's obviously not about debris/hairs/dust but germs.
In other words, if a person saw hairs/dust/debris in their jam that fell on the floor, they wouldn't eat it anyway.
But if something less sticky (and more solid) was dropped, say an apple or a pizza piece that fall on the bread side, they might pick it up, sweep it a little, and eat it.
In fact, 5-second-rule or not, most people will be fine for doing so anyway, as long as they do it on their relatively clean home -- with germs that they are usually in contact anyway.
Eh, sure, if it's a pretzel or a piece of candy or whatever, we (in my country) will pick it up, blow on it a bit, wipe it a bit and eat it. It depends on where it fell and how sticky the food is, but obviously "time spent on the floor" isn't really a factor.

It might might not be a conscious following of the 5-second-rule, but I'm sure the people in your country would still pick it up fast and not let it collect germs kana eikosalepto before eating it.
I think the idea here is that a significant enough number to get you sick, haven't had a chance to set up shop. We eat germs all day, it's when we get too much at once that there is an issue.
so while gummy bears are least likely to gather germs, how about hard candy? also, what are the differences compared to your hands? what about a communal candy jar or shared food space?
while I understand the five second rule is just some silly fun I am still not convinced that much else is better. unless your using a completely sanitary environment with sterilized equipment you will always get some bacteria
"Study finds" Implies this is new knowledge and somehow news.
I've known that this is crap for a pretty long time, as I hope have other people. A more accurate title for this article might have been "Study confirms that 5 second rule makes no sense"
I wonder how human beings from centuries ago (and actual animals) have been able to survive without our clean like a lab environment?
Would it be possible that we overstate quite a bit the danger of everything?
I prefer my beer, cheeses non pasteurised and I prefer raw milk (after being boiled). And I think the food coming from puritans victorian inspired countries taste blend like the catholic religion.
Most unhealthy illegal (by brits laws) traditional french cooking I have eaten from Québec was tasting like real fucking good FOOD.
Hail to the artisinal food! fear not the propaganda from industrial food processors (unilever, procter&gamble, lactalis, nestlé ....)
Be curious, fear not (except if you are pregnant) and resist the messages of fear.
Short answer: They didn't survive. IIRC a significant portion of all humans born in past centuries simply died as infants/children, usually from things that are trivially preventable today with basic hygiene, good nutrition and antibiotics/vaccines.
Humanity as a species obviously survived because people simply had a lot of children to compensate the high mortality rates.
Dad, medical studies are not science ; for instance fat are goods, then bad then good again.
Son, Newton laws have been proven wrong by Einstein
Dear dad, Newton laws are still valid in the right domain, something proven wrong may be proven wrong at the edge but not in its core, if medecine was science, fat would always be good most of the time, except when ...
Yes, but we medics invented meta analysis that made the science better
You are mainly comparing apple and potatoes without blinking, and you are surprised the results of your studies are hardly reproducible.
Long story short; hygienists are leading medical science based on their religious believes (like Pasteur with alcohol) and believes are hardly a good way of leading studies, and I am used to live every day with a tenant of as soft science as psychology/philosophy/history that has a diabete type II for believing in the BS of his fellow «scientific» colleagues, and I do not know if I am angry or laughing.
Of course it picks up bacteria. Bacteria are numerous and everywhere. But we've lived with them so long that we can deal with unsterile environments for the most part. Most people for most of history were not germaphobes, and didn't even know bacteria existed. If eating something off the floor had a high chance of killing you, the human race would not have survived this long.
Only bacteria that have evolved to infect humans really scare me. So in a public place I probably would not pick something off the ground. But in my own house, I know no one there had tuberculosis. In my life I've eaten tons of berries and stuff that grow outside or even on the ground, and have never had a problem.
My philosophy is that I just don't waste food. Has nothing to do with "five second" rules. If I just spent time making an amazing sandwich, and it drops on the kitchen floor mostly intact. I'm sure as shit eating it. Obviously gloppy sauces, and subway tunnels, I'm not going to scrape off the ground. For the rest, that's why we have immune systems.
I'm pretty sure the "5 second rule" is just something people (like myself) use to justify doing something gross, such as eating something that was dropped; and at least in my case, I never believed for a minute that it was "sanitary" if it spent less than 5 seconds on the floor.
It's more a mental thing ... if it's only been there for 5 seconds, it's cool. If it is longer than 5 seconds, well, then you're eating food that's been sitting on the floor. Now that I'm typing it, it makes even less sense -- but that doesn't mean I'm going to stop doing it. I've made it 30+ years without side-effect ... ha
Yeah, many of the comments talk about bacteria, evolution, our immune systems being able to deal with bacteria, and that is all fine and good.
But what about chemicals and cleaning supplies? Eg the floors in a restaurant (and tables, too) get cleaned with some strong chemical products. That's definitely not food grade and no amount of evolving is going to help you deal with that. I see people put their forks, etc, on directly on table surfaces that were previously wiped with a cleaning cloth and I think that's careless. The floor would be even worse.
Eating from your dog is fine and probably has health benefits. Eating from a (chemically cleaned) floor is still not.
Wouldn't the napkin be touchin the table then? Or do you ask for a fresh napkin so you don't have to use the one from the table? And ask about the storage of the napkins and silverware, in comparison to any cleaning solutions or other chemicals?
> Yeah, many of the comments talk about bacteria, evolution, our immune systems being able to deal with bacteria, and that is all fine and good.
It also ignores parasitic worms. People go blind from eg toxocara, which is spread by dog faeces. Only about 700 people per year in the US, but it's avoidable and preventable blindness.
> . I see people put their forks, etc, on tables that were previously wiped with a cleaning cloth and I think that's careless.
The amount of cleaning chemical you're going to eat by putting a fork on a table is tiny, and if that causes harm putting bare forearms on the table is going to be risky too.
The dose makes the poison. The amount of lysol residue or whatever that gets on your dropped skittle is tiny. You probably eat it all the time, whenever you touch the table and then your food.
Anyway in general danger of exposure to chemicals is seriously overblown. I love this E.T. Jaynes quote:
>...for virtually every organic substance (such as saccharin or cyclamates), the existence of a finite metabolic rate means that there must exist a finite threshold dose rate, below which the substance is decomposed, eliminated, or chemically altered so rapidly that it causes no ill effects. If this were not true, the human race could never have survived to the present time, in view of all the things we have been eating.
>Indeed, every mouthful of food you and I have ever taken contained many billions of kinds of complex molecules whose structure and physiological effects have never been determined – and many millions of which would be toxic or fatal in large doses. We cannot doubt that we are daily ingesting thousands of substances that are far more dangerous than saccharin – but in amounts that are safe, because they are far below the various thresholds of toxicity. At present, there are hardly any substances, except some common drugs, for which we actually know the threshold.
If you really wanted to test the five second rule, you'd have to be broader. Who is overall better off?
1. The person who NEVER eats food off the floor
2. The person will ALWAYS eats food off the floor
3. The person who follows the 5-second rule
I wouldn't be surprised if the 5 second rule gives its followers a net benefit. You're slightly more likely to get sick, but you waste less food and live a less paranoid life.
Purely anecdotal, but I eat lots of unpasturized fermented food, I re-use silverware/dishes/cutting board with just a quick moist cloth wipe, and I haven't been sick in around 7 years. Occasionally I'll notice increased mucus and mild inflammation my nose/throat that tells me I've been exposed to something, but it always goes away within about 8 hours.
The thing that really a noticeable difference in my immune system was working in a bar. You come into contact with so many people, many of whom don't take good care of themselves, and end up collecting / washing the glasses they have been drinking out of, shaking their hands, handling their IDs, wrestling them out of the building. I was sick constantly for like six months, but after that, I almost never got sick again.
Sadly, it appears to be wearing off. I was sick for a fair bit last winter, and it'll probably be the same again this year.
Er... Please tell me tax money wasn't wasted on this study. We all joke about it, but come on, are you really telling me someone wasted money studying this? We all know germ transfer is fairly immediate.
My whole family spends much of our time filthy from living on and operating a farm, and I n your average shoes off household, you're less likely to get sick eating something that just fell on the floor than you are to get sick. That's not to say you won't get sick, it's also not to say that what you catch won't be fatal, but really... we all laugh and joke and yell "5 second rule!" before knowingly taking our lives in our own hands and guess what? So far, we're still all here and so far we spend a lot less time sick than many people we know.
We know the 5 second rule is bullshit, we don't need a study to tell us that, we're not idiots. Some people are into adrenaline sports and driving wrecklessly, we play 5 second rule Russian roulette. It's good for your immune system, until it kills you.

What's wrong with just explaining that they shouldn't eat stuff from the ground. Period?
Wasting food for no good reason. And making them paranoid about germs.

But on second read, I'm guessing you meant to rinse off the cat hair?
I generally brush it off and eat it nevertheless.

It would seem boiling milk defeats the purpose of raw milk.

If anything, it's probably been of some marginal benefit -- keeping your immune system on its toes.
But what about chemicals and cleaning supplies? Eg the floors in a restaurant (and tables, too) get cleaned with some strong chemical products. That's definitely not food grade and no amount of evolving is going to help you deal with that. I see people put their forks, etc, on directly on table surfaces that were previously wiped with a cleaning cloth and I think that's careless. The floor would be even worse.
Eating from your dog is fine and probably has health benefits. Eating from a (chemically cleaned) floor is still not.
What? If you can't put your forks on the table where can you put them?
I always put my fork on the table, that's what the tables for.
How do you lay your table?!
A posh restaurant would have a table cloth that would be cleaned daily with less harmful chemicals.
It also ignores parasitic worms. People go blind from eg toxocara, which is spread by dog faeces. Only about 700 people per year in the US, but it's avoidable and preventable blindness.

I'm sticking with it, but not for watermelon.
I'll get a sniffle for a day and then that'I'll be the end of it. I haven't been sick in a year.
