Risks
for House Fly
The real hazard is contamination, not bites: a fly picks up germs while feeding and breeding in filth, then deposits them on food. House flies are suspected of carrying dozens of human diseases, on the order of 65, among them typhoid, dysentery, cholera, anthrax, and TB. Source: https://extension.psu.edu/house-flies
The CDC explains how: as the fly most common in homes and food settings, the house fly is the one most likely to move pathogens such as Campylobacter, carrying them on its feet, mouthparts, legs, and body and shedding them onto food directly or in what it regurgitates and excretes.
