Flies on Food
The common housefly is a nuisance and can pose health risks to humans and animals alike. Houseflies are known to be carriers of over 100 diseases and can transport pathogens that cause diseases like anthrax, tuberculosis, typhoid and cholera from location to location.
When flies feed on waste, they collect pathogens on their legs and mouths. These pathogens are then transferred to food on tables or counters when a fly lands again. Flies regurgitate on solid food then they eat the liquid. They are capable of transmitting disease when they vomit, groom themselves or just walk on surfaces.
