How do flies and mice pass food-poisioning bacteria on to food?

Answer 1

Imagine this . . .

A fly lands on your hamburger or piece of cake. They can eat only by spitting onto the food to dissolve it. Then they suck up the juices. While there, the fly defecates onto the food. And its feet drop minute pieces of whatever it was sitting on before. I forgot to mention that it just flew in from visits to a dog turd and a rotting road kill.

Anything that fly does while on the food could drop enough of a load of pathogenic bacteria to make you sick.

Answer 2

Flies are very nasty creatures. They eat anything and everything from poo to your food and then back to poo. The way they eat is to regurgitate onto the food to dissolve it. Then they suck up the goo. On their feet and body, they also carry bits of whatever they have landed on before - and that could include rotting flesh or feces. Both of these methods can contaminate food with enough organisms to make someone sick.

Answer 3

The female fly lays eggs in the food. The food acts as a supply of protein for the flies which have just hatched. The flies' waste products are toxic. They irritate the body and upset its normally functions.

Hope it helped :)

Answer 4

Flies regurgitate their food, meaning, as they eat they chew their food and spit it back out, and continue the process while consuming small portions. Flies also lay their larva, or babies in our food which eventually hatch and become maggots.

Answer 5

a fly lands on poo then on your food = food poisoning
