I recently found out that a kitchen floor apparently is about as dirty as a toilet bowl, and filled with quite a bit of bacteria.  That’s why I get so grossed out when I see kids and even adults drop some food on the floor, pick it up again, dust it off a little, exclaim “five second rule!” and then continue to eat it.  That is probably just as dangerous as eating uncooked food.  Both have bacteria, yet sometimes we don’t even give it a second thought!  I mean at least put it in the microwave for a couple seconds or something, or the next time you drop something on the floor, let the dog finish it off for you.
