The five-second rule proves, to the shock of children and drunk people the world over, insufficiently prophylactic against salmonella and other bacterial buzzkills.

    If Americans were less obsessed about hygiene, we'd probably have a lot healthier kids. There's a lot of scientific support for the Hygiene Hypothesis, which just means that people who ate dirt (and observed the 5-second rule) as kids are healthier adults.

    A little dirt and a few germs in your body now and then just helps your immune system stay strong. That's my 2 cents and I'm sticking to it.

    I have three dogs in my house. There is no 5 second rule!

      Hah! so true, my mother has large dogs. You couldn't even let the food get below your waist, let alone the floor.

    Was it above the rim or below the rim?

    I'm sure if you keep your floor clean and washed on a regular basis, you're probably alright with a dropped cookie.
    On the other hand, if your floor has got salmonella bacteria all over it – you've got way bigger problems than dropped food.

    MST has it right. The 5-second rule is about perception ("no, I'm not REALLY eating off the floor"), not about germs.

    I still believe in 5 second rules, whether it's off the floor or the counter. I once even spat my gum on the highway while drunkenly laughing at rechewed that and lived to tell. C'est la vie.

    Did this really surprise anyone? I first learned the 5-second rule in middle school; it's just a way to justify eating food that's picked up on the floor and look 'cool' while doing it. I never thought of it as being linked to hygiene.
