Flies are everywhere, and even when we don't see them they're hanging around somewhere waiting for a chance to get at our food.
They aren't exactly subtle about their intentions either, and without hestitation a fly will land on our food right when we're in the middle of chowing down, making us wonder if the food is still safe to eat.
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.
