Where housefly picks up dysentery bacterium?

Houseflies can pick up dysentery bacteria, such as Shigella, from contaminated food, water, or surfaces. They often land on feces or decaying organic matter, where these bacteria thrive. Once they come into contact with these pathogens, the flies can carry them on their bodies or in their saliva, and subsequently transfer them to human food or surfaces, facilitating the spread of infection. This highlights the importance of sanitation and hygiene in preventing the transmission of diseases associated with houseflies.
