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.
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.
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 :)
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.

What disease can mice give to food?
Food poisoning. Mice carry a multitude of bacteria that comes from their environment, so depending on where the mouse has been, depends on what they'll leave behind.
Kinds of lizard food?
Listed from smallest lizard food for small lizards to largest lizard food for very large lizards: fruit flies, flies, small crickets, crickets, large crickets, grasshoppers, baby mice, mice, small rats, rats, large rats.
Do rats and mice carry bacteria on their bodies?
Yes. Every single living creature has bacteria. But the amount of bacteria on each of the rats or mice depends on where they scurried/go to.
What effect did an injection of dead S bacteria have on mice Griffith studied?
The mice died
Is it ok to use coffee beans that mice have been into?
No mice can have bacteria on them that can make you very sick
Can mice eat flies?
They are omnivores, so they might eat flies.
Are bacteria only found on rats mice and cockroaches?
No
What do wild newborn mice eat?
Crush mice food or mice pellets
Why do you always put waste food in a bin?
If you don't put waste food in a bin it will attract fruit flies, house flies, wasps, mice, rats, cats, stray dogs, skunks, raccoons and bears. Not all of these make good pets.
What did Griffth observe when he injected a mixture of heat killed disease causing bacteria and live harmless bacteria into mice?
Griffith discovered that the mice still died, indicating that the harmless bacteria had been transformed into disease-causing bacteria by a hereditary factor from the heat-killed bacteria. This experiment laid the foundation for the discovery of bacterial transformation by Avery, MacLeod, and McCarty.
What result from Griffiths experiment suggested that the cause of pneumonia wasnt a chemical poison?
To find out, he took a culture of these cells, heated the bacteria to kill them, and injected the heat-killed bacteria into the mice. The Mice survived, suggesting that the cause of pneumonia was not a chemical poison released by the disease-causing bacteria.
In an experiment DNA from dead pathogenic bacteria was transferred into living bacteria that do not cause disease These altered bacteria were then injected into healthy mice These mice died of the?
This experiment demonstrates the concept of transformation, where genetic material from one organism is taken up by another resulting in a change in phenotype. The injected bacteria likely acquired the pathogenic genes from the dead bacteria, causing them to become virulent and resulting in the death of the mice. This highlights the importance of understanding genetic transfer mechanisms and the potential dangers of gene transfer between organisms.
