Doctors claim that flies are twice more dangerous than any other insects. The reality is: flies eat some of the most disgusting things you could ever imagine: feces, trash, rotten meat, dead animals.
Another nasty fact is that flies don’t chew, they spit enzymes that dissolve their food and then they suck it.
Those enzymes aren’t the reason why flies are contagious and dangerous. Flies attach bacteria and viruses on their body and they spread it from one person to another. When a fly lands on your food, it transfers the bacteria and viruses on your food. Flies can even transfer diseases such as: cholera, Typhoid fever and dysentery.
The main conclusion is this- If you see a fly touching your food, throw that food away.
