Of course, this only applies to solid food. For example, cookies without cream or a roll without butter on it. But gradually the “permissive” rule was extended to some other food products.
Surprisingly, even some doctors believe that what is quickly picked up from the floor does not need any treatment. At the same time, for some reason, no one asks himself the question: “Are microbes really so slow that they do not have time to” settle “on the fallen food?”
The five-second rule was never in doubt. Until there were people who wanted to test it experimentally.
Leaving aside the question of who invented the five-second rule and when. It exists, is perceived in society as an axiom that does not require proof.
The very first scientific study of the generally accepted dogma of the rule was conducted in 2003 in the United States at the University of Illinois. Trainee Gillian Clarke and her research advisor, Meredith Agley, came up with an ingenious approach to test the rule.
They placed E.coli microbes on an apparently clean floor and then dropped food on it and quickly picked it up. The food was quickly examined under a powerful microscope. It turned out that the food in all cases of falling on the floor had E. coli, although they were not on the food before the fall.
It is curious that for this experiment, the employees of the named university received the Shnobel Prize, as for the most useless scientific experience of the year. If we approach the issue from the point of view of the founders of this prize, then I must say that it is a curiosity and parodies the Nobel Prize.
However, the value of a scientific experiment is obvious: it proved that there is no five-second rule for germs.
This same conclusion was confirmed by scientists in 2016. But Anthony Hilton, academician of the Aston University of Birmingham, put a fat point on the topic in 2017. He concluded that the five-second rule can only be trusted if the floor is perfectly clean. And such a floor, as you know, occurs only in a sterile operating room. The academician’s humor is that no food is allowed in it.
Curiously, Wikipedia is also ironic about the five-second rule. You can only smile after reading these words in it:
“What I quickly picked up, I didn’t seem to drop it,”
“What did not lie for long, did not fall at all!”
“In the forest, every speck is a vitamin”,
“There is no dirt in the forest – there are only vitamins in the forest”,
“The microbe is not a fool – it won’t get into the mud” …
However, the named encyclopedia states that
… any germs that can transfer to the fallen food within a few seconds will be in such small quantities that they are easily destroyed by stomach acid and do not harm the body.
But it’s better to focus not on the dubious rule of five seconds, but on the fact that the safest thing is not to eat something that has fallen to the floor. Especially if the floor has not been washed for a long time, dust is visible on it and the room has free air access from other rooms and from the street. If you follow this rule, and not the five second rule, then you will certainly be healthier.
