Video: Risks of digesting food caught by flies

What happens if you eat the food that flies home?

Flies feed by using a long nose like a hose to howling food in liquid form.

House flies are non-teeth insects. They eat by using a long nose like a hose to howling food in liquid form.

When parked on solid food sources, house flies will burp a special saliva on the food. This saliva will liquefy food, allowing them to be absorbed. And this is why flies' saliva is so dirty and dangerous.

Eating food with flies and beans can lead to the risk of many bacterial-related dangerous diseases such as typhoid or cholera.
