House Flies & Diseases
Global pests, house flies are common insects in Canada and the rest of the world. Closely associated with humans, the house fly poses numerous health threats because of its tendency of breeding in garbage and other filthy decaying matter. House flies have the ability to pick up, carry, and spread microorganisms that potentially cause disease. At least 65 different diseases are known to be linked to house flies, including anthrax, cholera, dysentery, leprosy, tuberculosis, and typhoid fever. Some of the most common pathogens transmitted by house flies include Salmonella and E. coli bacteria, which cause food poisoning.
House flies transmit diseases mechanically by unwittingly picking up pathogens from contaminated sites and physically carrying the pathogens to other locations. Decaying organic matter and animal feces are full of pathogens. When a house fly rests on and walks across such materials, it picks up the pathogens on its body hair and the sticky pads on its feet. When house flies enter indoor structures, they often come into contact with food preparation surfaces and human food, thereby spreading the disease-causing organisms to materials directly involved in the process of preparing and eating meals. House fly saliva and feces can also contaminate food items and cause humans to become ill.
