But there is more, these flies can transmit food-borne pathogens, toxins and resistance. In fact, they are known to carry and spread; cholera, conjunctivitis, dysentery, gastroenteritis, salmonellosis, tuberculosis and typhoid fever. House flies feed by regurgitating their stomach contents onto their food to liquify them, any bacteria living in their oesophagus will be transmitted to the item they are consuming. You can catch a house fly transmitted disease by eating any food or drinking liquids that a house fly has: regurgitated, defecated, urinated, or landed on. Bacteria living within their digestive system will be transmitted to items which they defecate on through their feces. House flies also accumulate the bacteria on the tiny hairs on their legs and body so when they land on a food many of these pathogen are transferred.
