The 5-Second Rule is Bogus, Say Rutgers Researchers
Consumers have long regarded the popular notion of the 5-second rule. This is when food falls to the floor and--if you can pick it up within 5 seconds--it is deemed safe to eat.
But, scientifically, is that really the case? No, say researchers at Rutgers University. They found that bacteria may transfer to food that has fallen on the floor no matter how fast you pick it up.
