(KETK) Tyler, TX — Depending on the crowd, if someone accidentally drops a piece of food on the floor, sometimes they'll hear someone else shout, "Five second rule!"
The rule is, you then have five seconds to pick up the snack, or else call it a loss and toss it in the trash.
Now, a new study justifies what some say is an "absurd" rule.
Researchers in England treated an indoor floor with bacteria..
Then, they dropped food on it.
They found a direct correlation between the amount of time food was left on the floor, and how much bacteria had attached itself to the food.
Researchers say chowing down on anything that has been on the floor longer than five seconds, probably isn't a good idea.
