I actually tried the 'five second rule' with a piece of cheese last week
I dropped a slice of cheddar on my kitchen floor, which I had mopped two days before, and left it for a solid five seconds. I picked it up, ate it, and got a stomach ache about three hours later. My friend always said the rule was a joke, but I thought a clean floor was safe. Now I'm wondering if the myth is just wrong, or if it depends on the surface. Has anyone else tested this and been totally fine, or did you get sick too?
