Well, here's the thing- flies eat really gross stuff like poop, rotten meat and toxic trash, and they vomit enzymes onto their food, or our food as the case may be, before they eat it.
But that's not how flies transfer some of the over 200 types of bacteria they may be carrying around, because as this DNews video shows the nasty stuff is actually sitting on the little hairs all over their legs and body.
