from forbes.com: If you’ve ever consumed food after dropping it on floor and then wondered what sorts of diseases you might be contracting, here’s a new study that may put your mind at ease (or not). New research out of Aston University in the U.K. finds that there may be some truth to the old wives’ tale, often called the “five second rule,” which suggests that it’s ok to pick up dropped food as long as it’s within a five-second limit. Many people halfheartedly teach their kids this first “rule” of food safety, because, hey, it’s better to risk disease than to waste food. But take this with a grain of salt. The study doesn’t appear to be peer-reviewed or published anywhere. We need other researchers to have a chance to review these results and then re-do the experiment before we can be sure it’s OK to eat that bagel you just picked up.
