Must food be thrown away if it falls on the ground?

Suppose you bought a pair of spicy chicken wings with meat fragrance with the only 10 yuan you have. When you are ready to eat them happily, the bag containing the wings falls to the ground. Your heart is breaking. Subconsciously, look around and there is no one around! So do you pick them up right away, pretend nothing happened and continue to chew them, or do you drop them into the garbage can with blood dripping inside?

Of course, for most people, after food falls on the ground, they will definitely not want to pick it up and eat it. But, you know, you have only 10 yuan! And I haven’t eaten for a day! Think about it. Are you picking up these hot and spicy chicken wings?

Your concern, er, of course, is that it looks and feels very dirty. Think about how many pairs of shoes have passed through the place where the chicken wings lie. They may have gone to the toilet or stepped on dog shit. Salmonella, Escherichia coli, and other bacteria that cause various diseases may have climbed onto the surface of chicken wings.

is the five second iron rule reliable

In 2007, Dr. Paul Dawson of Clemson University published research in the Journal of Applied Microbiology, denying the reliability of the 5-second rule. He threw sausage and bread on the ceramic tile, carpet and wooden floor contaminated by Salmonella, let the food stay on it for 5 seconds, 30 seconds and 60 seconds respectively, and recorded the number of bacteria transferred to the food at different times.

The results show that the amount of bacteria transferred to food depends largely on the contaminated area of the food surface. The material of the floor will also be affected. For example, food dropped on the carpet will transfer less bacteria, less than 1%. But when food comes into contact with ceramic tiles and wooden floors full of bacteria, 48% to 70% of bacteria are contaminated by food within 5 seconds.

All this shows that whether food is contaminated by bacteria has nothing to do with the length of time food falls on the ground.

So, are you going to give up those spicy chicken wings? Don’t be impatient, young man. Nevertheless, Dr. Dawson frankly said that even if your food is contaminated with bacteria, what will happen? Eat it, and your body will be fine! Because the bacteria above are rarely pathogenic.

Recently, Mike Meacham, an engineer at NASA, conducted another experiment to confirm that the “five second law” is true. However, the premise is that the side where the food falls on the ground is dry.

Only when the food dropped on the ground is wet, or the ground is wet, can such food really cause problems. Because Escherichia coli, Salmonella and Listeria all like a humid environment very much, they will absorb the necessary nutrients from the water and then grow and reproduce.

Once wet food falls on the ground for more than 30 seconds, it will be contaminated with 10 times more bacteria than the food picked up after falling on the ground for 3 seconds.

Similar to the conclusion of Dr. Dawson’s experiment, the study also found that the type of ground on which food fell is very different. Generally speaking, it is better for food to fall on the carpet or blanket than on the linoleum, because the contact area between food and the surface of the carpet or blanket is smaller than the contact area with the linoleum, so that bacteria will spread to the food more slowly.

women tend to eat food on the ground.

This is beyond your expectation.

Gillian Clark, a high school girl from Illinois, USA, was the first to make statistics on the 5-second rule. Her research report said that 70% of women and 56% of men were familiar with the 5-second rule among the respondents, and women were more likely to eat things that fell on the ground.

Aston University in the UK also conducted a survey and found that about 87% of the respondents believed in the five second rule, of which 55% were women.

Why do women who seem to love hygiene take such risks? According to Xiao Jiu’s guess, maybe most women are like Xiao Jiu and are typical eaters.

After all, can we pick up the food that fell on the ground and eat it? Xiao Jiu feels that we don’t have to be too obsessed with the five second rule. Some netizens have concluded that it mainly depends on three points: first, whether the food is expensive, second, whether it tastes delicious, and finally, the most important point is whether there is anyone next to it

It’s that simple.
