The 5-second law has scientific basis only under certain conditions (clean ground and less bacteria are indispensable), but it is another matter in daily environment, because there are extremely complicated conditions and environments in daily environment, which are not unique. In daily life, it is inevitable that food will fall to the ground. Do you choose to pick it up and continue eating or throw it away? Most people's choice may be to throw it away directly. If the ground is dirty, don't eat the food that falls on the ground. After all, there is a good saying: health comes first when the disease enters the mouth.

Of course, many people believe it? The five-second law? Think you can still eat it after five seconds. What do you mean? The five-second law? That is to say, after the food falls to the ground, it can be eaten within 5 seconds, so people often say? The five-second law? Really scientific? Bacteria and microorganisms are invisible to the naked eye. There is a paradise for bacteria and microorganisms around us. They are always around us. Can food be picked up in 5 seconds without being eroded by bacteria? Do you want an authoritative result, or do you want to look at it scientifically? Five seconds? Is the law accurate?

When food falls and comes into contact with contaminated tiles or floors, bacteria will run to the food in extreme time, and the number of bacteria attached is the same regardless of the type of food; Scientific experiments show that bacteria will attach to food in a short time, whether it is 5 seconds, 10 seconds or longer, the bacteria are the same.

So can the food be picked up within 5 seconds after landing? The five-second law? Science? The situation is different and the result is different. First of all, it depends on the type of floor, tile floor and solid wood floor are not good. Secondly, places like kitchens and bathrooms are high-risk areas for bacteria.

For the sake of health, it is best not to eat.
