If you eat fly eggs accidentally, generally, nothing serious happens because the stomach acid destroys the eggs. The body digests them like any other small particles, and they don't typically hatch inside the stomach. Eating a few fly eggs is unlikely to cause harm to a healthy person.
However, there are some health risks if the fly eggs are contaminated or if you consume larvae (maggots) that hatch from those eggs. Maggots can carry bacteria such as Salmonella and E. coli, which can cause food poisoning with symptoms like vomiting, diarrhea, and stomach upset. In rare cases, fly larvae can cause a condition called intestinal myiasis, where larvae survive and feed in the intestines, leading to symptoms like abdominal pain, vomiting, and diarrhea.
In summary:
- Occasional accidental ingestion of fly eggs usually poses no health risk.
- The main danger comes from bacteria or pathogens carried by flies or from consuming maggots from spoiled food.
- If symptoms like severe digestive issues appear after ingestion, medical attention should be sought.
For best safety, it’s recommended to discard food that has visible fly eggs or larval infestation to avoid any potential risk.
