Oh how sad.

You know what rule I’m talking about. Your kid drops something on the floor and you allow them to pick it up and eat it based on ‘The 5 Second Rule’. What? Is that just me? In 5 seconds, nothing could have happened to that sandwich right?

Wrong. According to, even after 1 second -the food should be thrown away.

It’s probably not even safe to follow a 1-second rule: The transfer of bacteria from a contaminated surface to food is almost instantaneous—or, at the very least, quicker than your reflexes. In one study, Clemson University food scientist Paul Dawson, PhD, and students contaminated several surfaces (ceramic tile, wood flooring, and carpet) with Salmonella. They then dropped pieces of bologna and slices of bread on the surfaces for as little as 5 seconds and as long as 60 seconds.

After just 5 seconds, both food types had already picked up as many as 1,800 bacteria (more bad bugs adhered to the moisture-rich bologna than the bread); after a full minute, it was up to 10 times that amount.

Ah poo! Literally.
