Food can be eaten if picked up and eaten within 3 seconds of falling on the ground, because bacteria can’t run to the food, wrong! This is definitely the worst time a bacterium has been hacked. Not to mention three seconds, the “aged group” of bacteria can also be transferred to food when the food falls on the ground.
As early as 2006, Clemson University in the United States specifically studied this test and found that no matter whether it was 3 seconds, 30 seconds or 60 seconds, the bacteria contaminated on the food were almost the same. So do n’t be delusional, “As long as my hand is fast enough, bacteria ca n’t keep up with the potato chips in my hand”!
