    Five-second food rule fails microbiology test

    CHICAGO - A high school senior in the U.S. has dealt a blow to the gastronomic principle known as the five-second rule.

    The rule states if food falls on the floor and remains there for five seconds or less then it's fine to pick it up and polish it off.

    Jillian Clarke of Chicago High School for Agricultural Sciences put the rule to the test.

    Clarke says the rule was started by Genghis Khan. He apparently considered food safe to eat so long as it had been on the floor for 20 hours or less.

    As part of her seven-week internship at the University of Illinois at Urbana-Champaign, she tested the five-second rule around campus.

    The researchers tested how many microorganisms transferred onto food from rough and smooth tiles. Gummy bears and fudge-type cookies were tested - the two-most commonly dropped and eaten snacks.

    The campus floors were actually quite clean. They found fewer than 20 so-called colony-forming units of E. coli on the floors. The lower limit for detecting the microbes is 25 colony-forming units.

    When the researchers purposely inoculated food with bacteria, they found it doesn't take long for the bugs to contaminate a morsel.

    "People think if it made contact for only five seconds then it is OK to eat but it's false because if you do drop anything full of microorganisms such as E.coli, it will transfer and transfer immediately," Clarke told CBC Radio's As It Happens.

    The texture of the food and floor tiles also made a difference, she found. Microbes transfer faster on smooth foods like gummy bears falling on smooth tiles compared to rough tiles or fudgey cookies.

    If a parent threw away every piece of a child's food that touched the floor, the food bill would triple. It ALL goes on the floor at some point.

    I honestly believe this rule was made up for one reason. When your kids drop their food on the floor for the umpteenth time, you want to make them eat it anyway. So you say "five-second rule" and shove it in their slobbering little faces.

      It also makes sense to use this for children, in a way. Considering your floor, if you keep it clean and don't have a dog stepping in their urine and feces and walking across it all the time, doesn't exactly have tons of dangerous germs on it. It still has plenty though - but that isn't necessarily a bad thing.

      I've seen a lot of studies done that suggest that children need their immune systems worked a bit more when they're younger to let them develop properly. That perhaps kids whose parents keep things too clean never have their immune systems worked properly, thus they can become hypersensitive, and cause issues with asthma and allergies.

      The immune system evolved in an environment when it was constantly being used. If it doesn't get used, it probably goes overboard.

      As a single data point, I remember reading an article talking about Crohn's Disease (inflammation and ulceration of the intestines and bowels) being treated by having patients drink a solution containing eggs of parasites that live in that area of the body. The immune system fights off the parasites, instead of being busy fighting the body. The parasites don't stay - they get killed, so the patients have to drink the solution every few weeks or so - but all the symptoms disappear.

      Regardless, when I am a parent, the five-second rule will definitely stay, and if the kids play in the sand or dirt and get a little dirty, I'm not going to freak out - it's good for their body in the long run.

    Preventing wasted food, my ass. It's actually a way to prevent other greedy folk from knocking the goodies out of your hand, then grabbing it when it hits the ground. After all, if they can't pick it up before the five seconds is up, it's deemed contaminated and all their knocking you around was wasted effort. ;)~
