Is food dropped on the floor safe to eat?

Scientists have recently studied whether or not food dropped on the floor is truly safe for consumption.
We're all guilty of it: dropping a chip or a grape on the floor and quickly snatching it up again only to pop it directly into our mouths. But is it truly safe to do that ? Until now there hasn't been any significant proof one way or the other.

A recent study conducted at Manchester Metropolitan University explored this idea by examining various foods that were dropped and left on the floor for 3, 5 and 10 second intervals. The results suggested that processed foods with the highest sugar or salt content were the safest to consume after hitting the floor.
Who hasn't picked up a piece of dropped food from the floor, given it a quick blow and assumed it was still safe to eat?To many of us, it is second nature to apply the age-old pseudo-scientific 'three second rule' on such occasions, telling ourselves we're safe if the food hit the floor only momentarily.

With the amount of homeless people scouring trash bins these days, picking up a dropped morsel from your OWN clean kitchen floor, probably isn't going to kill you. If these homeless ones who I've observed over the years are still walking around after all they've gathered from who knows where, I guess we'll easily survive the dropped morsel on the floor syndrome. Should food become scarce in the near future (maybe much sooner than we think) these guys will have a better chance of surviving with the left overs than us.

I always figured the acid in my stomach would kill anything from a short term drop. Or the parasites in my bowels would finish off anything too harsh for acid. If all else fails, there's the bugs up my ***.

LOL. I for one can say that I most likely have as a baby and toddler but not as a child, teenager, or an adult pick food up off the floor. I find it to be gross.

I usually rinse it off with cold county tap water...it has so much chlorine in it, probably kills every germ and virus. My dog and cats usually slurp up everything else.
