Study shows ‘5 second rule’ may be true


UNITED KINGDOM (WIAT) — The so-called “Five Second Rule” is something most people have heard of, but oftentimes the validity of the rule has been questioned.

The rule means that if food is dropped on the floor and scooped up within five seconds, it’s safe to eat it.

As it turns out, there may be some validity to that thought.

United Kingdom researches studied how much bacteria gathered on food after staying on the floor from three to 30 seconds.

The results revealed the longer food stayed on the ground, the more bacteria it gathered.

The type of flooring also played a factor.

The study found there’s less bacteria on carpet.
