You know when you're just about to take a big bite out of a lovely meal… and then a fly lands on it.
Most of the time you swat it away, right? Well, turns out you should probably bin it.
Why? When a fly lands on your food, it apparently gets sick. As in, it actually throws up on your grub. Lovely…
A recent survey asked participants what critter would make them run a mile from a restaurant: Rodents, flies, cockroaches, ants or snakes?
The majority said that cockroaches would make them flee, however scientists say that flies carry twice as many germs on them.
Flies aren't able to actually chew their food, so they have to throw up enzymes in order to slurp their grub up.
So, basically if a fly lands on your sambo and wants a bite, it will puke on it.
Also, flies like to eat things that we find revolting (trash, rotten animal carcasses, faeces), so the real danger when a fly lands on your food is actually it's body.
Germs from all those disgusting things a fly lands on clings to the hairs on the fly's body, so they pick up a host of bacteria and viruses.
So, moral of the story? Don't at anything a fly lands on. We definitely won't after finding this out.
