Five second rule

Interesting

From Health magazine, Nov 2007, page 16

Q. Is the five-second rule for dropped food accurate?

A: Surprise! Even food that's been on the floor for 30 seconds is safe to eat. Last May, two college students proved this by dropping apple slices and Skittles candy on the floor. They found bacteria only on the apples that had been left on the floor for a minute or more, and only the Skittles that had been there a full five minutes.
