STEC infections are primarily caused by the ingestion of human or animal feces. Even small amounts of feces that are not visible to the naked eye can be found in food or beverages. Unpasteurized milk and water contaminated by livestock are common carriers of the infection. Additionally, coming into contact with cattle feces or the feces of other humans can increase the risk of infection. Certain high-risk foods, such as apple cider and soft cheeses made with raw milk, also pose a significant threat. It is worth noting that produce can be a common source of infection as well, as feces may be present during cultivation or can contaminate the produce during preparation or serving.
Methods of E. coli Infection
There are various ways in which a person can contract an E. coli infection. These methods include working closely with livestock or providing care for individuals with incontinence, which are considered as obvious risk factors. Additionally, consuming undercooked meat or foods that have been prepared with unwashed produce can also lead to infection. Another common method of infection is through the consumption of contaminated food that has been prepared by individuals who did not adhere to proper hygiene protocols. Furthermore, it is possible to contract STEC (Shiga toxin-producing E. coli) by swallowing contaminated lake water or by coming into contact with surfaces at places like petting zoos or similar environments.
