- The answer depends on how many bacteria are on the floor and are picked up by the food
- Carpets are slightly better places to drop food than wood or tile
When you drop a piece of food on the floor, is it really OK to eat if you pick up within five seconds? This urban food myth contends that if food spends just a few seconds on the floor, dirt and germs won't have much of a chance to contaminate it. Research in my lab has focused on how food and food contact surfaces become contaminated, and we've done some work on this particular piece of wisdom.
