Intestinal
Nothing will happen to you if you eat a fly egg. The fly egg will die.
Some flies deposit their eggs on or near a wound or sore, the larvae that hatch burrow into the skin. Certain species' larvae will move deeper in the body and cause severe damage.
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.
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.
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.
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.
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) .
House Fly (Musca domestica)
House flies typically lay eggs on animal feces and garbage. White, legless maggots (the larval stage) hatch from the eggs and grow to about ½ inch. When fully grown, maggots crawl away from their food source to undergo the pupal stage.
Homeowners typically find house fly eggs in moist, decaying organic material like trash, grass clippings, or feces. Elongated and pale in color, they appear in clusters and hatch quickly after being laid by the female fly.
Intestinal myiasis may go away on its own or your doctor may prescribe anti-parasitic medicine. After the removal of any type of fly larvae, your doctor will tell you how to keep the wound clean. Proper cleaning will prevent infection and recurrence of the myiasis.
Fly larvae can be killed with increased temperature. At 115° F, larvae begin leaving a substrate. At 120° or higher, they are killed.
The condition is not uncommon and is often misdiagnosed as pinworm infestation. Correct diagnosis by the clinical microbiologist is important to avoid unnecessary treatment. Materials and methods: We had 7 cases of intestinal myiasis.
They are also able to withstand very cold temperatures. Most likely, fly eggs or larvae contaminated food items long before the foods were placed in the fridge. Alternatively, a fly could have entered while the door was open, or past a faulty door gasket.
The development of the eggs into larvae (maggots) would be slowed down by refrigerating the meat and stopped altogether by freezing. But they would not be killed.
Flies lay their eggs in warm, moist areas such as decaying plant matter, rotten food, garbage, animal faeces, and carrion.
Not recommended. The length of time you'd have to microwave your food to kill any germs on it would ruin it.
The low oxygen levels in the gut usually will kill the maggots, but some survive intact because their outer layers are resistant to digestive enzymes.
Fly eggs are hardly visible to the naked human eye – making it difficult to spot a fly's egg even if you know just where to find them. Coming into contact with flies and their eggs is dangerous for your health and that is why you must avoid flies so you won't worry about their eggs.
Maggots are the larvae of flies, and they can carry harmful bacteria that may cause food poisoning. If your dog eats maggots, they may experience symptoms such as vomiting, diarrhea, and lethargy.
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.
House fly eggs resemble small grains of rice. The eggs hatch into larvae, also known as maggots, which range in size from about ¼-3/8” (7-10 mm) long. Maggots are cream colored with a greasy appearance.
Though Greenberg's experiment proves beyond any doubt that blow flies do lay eggs at night as well as by day, active attraction of these flies at night towards the oviposition medium had yet to be proved and the present experiment has been designed for this purpose.
