We all heard about the 5-second rule. Your mother always told you never to eat from the floor, but is it just an old wives’ tale? How long does it take germs to cross-contaminate food on the floor? cross-contamination can happen at different levels. Some are a higher risk than others. For example, when a piece of food falls on the floor versus food covered with a plastic barrier. So, if you drop a piece of say, bread, on the floor that is still in the plastic. The risk would be less than a piece of bread that is exposed to the floor.
