In most instances, spotting a fly on your food doesn't mean you need to throw it out. While there is little doubt that flies can carry bacteria, viruses and parasites from waste to our food, a single touchdown is unlikely to trigger a chain reaction leading to illness for the average healthy person.
Yes, just pick the fly out and pull out the piece of food it was on. If the food in the pot wasn't piping hot, I would suggest reheating it to kill any germs it left behind.
Intestinal myiasis occurs when fly eggs or larvae previously deposited in food are ingested and survive in the gastrointestinal tract. Some infested patients have been asymptomatic; others have had abdominal pain, vomiting, and diarrhea (2,3). Many fly species are capable of producing intestinal myiasis.
Flies lay their eggs in food they land on. Given enough time on top of your food, flies may take the opportunity to lay their eggs in it. You will not be able to see the eggs, but they are there. And within a few days' time, maggots will appear in the food.
House flies, for example, can spread diseases such as food poisoning and dysentery. Flies, including stable flies and mosquitoes (which are also classified as flies, or Diptera), can inflict painful bites while feeding on the blood of humans and other animals, and some species transmit disease.

Flies can spread many human diseases, such as salmonella, E. coli 0157 and campylobacter which can cause food poisoning. These can result in severe diarrhoea and vomiting and occasionally, more serious complaints such as kidney failure.
Females will begin producing eggs 48 hours after they have emerged as an adult. During her adult life, approximately 1-3 months, she is capable of producing 4-5 batches of 100-150 eggs. These hatch within 48 hours into smooth, white legless maggot larvae and after 3 moults mature into pupae.
As gross as it may sound, the answer is yes – a dead fly can turn into a maggot. This is because flies lay their eggs in decaying matter, such as dead animals or food, and the larvae that hatch from these eggs are maggots.
If you find maggots in the food or the trash, you can boil them to eliminate them. Sprinkling salt or an insecticide on them can also help you get rid of them. The main goal is to quickly eliminate the breeding site, which means removing the eggs and maggots and then thoroughly cleaning the area.
The good news is that because it's just a fly, the nastiness is only limited to the surface. DeSalle says that cooking the food will be enough to kill any foreign bacteria or eggs. So if it lands on a hot dog or burger, just throw it back on the grill real quick.
The effectiveness of microwaves is exposure-time dependent. About 60% of the larvae of blow fly species, Chrysomya megacephala lived after 7 sec of microwave exposure, most larvae died by 15 sec and all larvae were dead at 30 and 60 sec (Sripakdee et al., 2005) .
As their name suggests, drain flies lay eggs in the film that forms in drain pipes and garbage disposals. Standing water increases the chance these pests will breed and develop in the house.
Just make sure its deep enough to not smell and thus attract new living flies to the area. If you just want to throw out the contents, I would use a garbage bag, kitchen size (13gal) or even a bit larger.
Flies and other insects breathe through tiny openings along the sides of their abdomen called spiracles. These openings were filled with a liquid causing the fly to drown. The salt draws the liquid out of the spiracles allowing the fly to “breathe” again.
Flies lay their eggs in warm, moist areas such as decaying plant matter, rotten food, garbage, animal faeces, and carrion.
Flies, maggots, and others flock to the decaying flesh within minutes and begin to lay eggs. According to the Nature Education Knowledge Project, “Carrion flies locate dead animals through a keen sense of smell; they can detect minute traces of decomposition odor in air currents.”
A housefly will likely die on its own from stress.
The interior of a home can be disorienting and stressful to a housefly, says Dave. If you've ever seen a fly bouncing on a window trying to escape, that's what will eventually cause its death.
The common house fly lays eggs that resemble grains of white rice. Within 24 hours of being laid, maggots emerge from the eggs. These maggots – or fly larvae – look like tiny, pale white worms.
Egg: The white egg, about 1.2 mm in length, is laid singly but eggs are piled in small groups. Each female fly can lay up to 500 eggs in several batches of 75 to 150 eggs over a three to four day period. The number of eggs produced is a function of female size which, itself, is principally a result of larval nutrition.
Flies may be more than a mere nuisance. They may also spread food poisoning bacteria like Salmonella enteritidis to chickens and their eggs.
The synanthropic house fly, Musca domestica (Diptera: Muscidae), is a mechanical vector of pathogens (bacteria, fungi, viruses, and parasites), some of which cause serious diseases in humans and domestic animals.
