A dirty dry floor in a public place is not dangerous for fallen food






There is a rule "bystropodnyatoe not considered to have fallen" - if you drop food on the floor and raise her right, she did not have time to collect the bacteria. In the English version it is called the rule of five seconds, during which the need to have time to remove the food from the floor. Studies have shown that this statement is wrongly - in the presence of microorganisms on a surface they are in contact with them in the product almost instantly. But most bacteria need for the existence of moisture, so dry floor, even in a public place with high traffic will not pose a serious threat to food.
