The 5 Second Rule - is it ok to eat food from the floor?

We've all quoted the 3 or 5 second rule -- if food falls on the floor, it's ok if you retrieve it within 3 (some say 5) seconds!

In other words, all the yucky stuff on the floor/ground/sidewalk won't have time to stick to our yummy stuff if we drop it.

But is it true?

Scientists investigated, and it seems for some foods, like cookies or processed ham, yes, it does work!

For other foods, like pasta, it's a fail. The wetter the food, the bigger the risk.
