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, cholera and malaria from location to location.

When flies feed on waste, they collect pathogens on their legs and mouth. 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. 

The dangers of food contamination are much greater in impoverished countries. Travelers should be cautious and refrain from eating foods that have experienced prolonged, open exposure to the air. Street carts and other outdoor food vendors pose a particular danger.
