People have gotten infected by swallowing lake water while swimming, touching the environment in petting zoos and other animal exhibits, and by eating food prepared by people who did not wash their hands well after using the toilet. Sometimes the contact is pretty obvious (working with cows at a dairy or changing diapers, for example), but sometimes it is not (like eating an undercooked hamburger or a contaminated piece of lettuce). These foods include unpasteurized (raw) milk, unpasteurized apple cider, and soft cheeses made from raw milk. coli O157 or another germ that health officials recommend that people avoid them completely. Some foods are considered to carry such a high risk of infection with E. Exposures that result in illness include consumption of contaminated food, consumption of unpasteurized (raw) milk, consumption of water that has not been disinfected, contact with cattle, or contact with the feces of infected people. Unfortunately, this happens more often than we would like to think about. Infections start when you swallow STEC-in other words, when you get tiny (usually invisible) amounts of human or animal feces in your mouth. Some types of STEC frequently cause severe disease, including bloody diarrhea and hemolytic uremic syndrome (HUS), which is a type of kidney failure. Other non-O157 STEC serogroups that often cause illness in people in the United States include O26, O111, and O103. Clinical laboratories typically cannot identify non-O157 STEC. Then, the positive samples must be sent to public health laboratories to look for non-O157 STEC. First, clinical laboratories must test stool samples for the presence of Shiga toxins. coli O145, are sometimes called “non-O157 STECs.” Currently, there are limited public health surveillance data on the occurrence of non-O157 STECs, including STEC O145 many STEC O145 infections may go undiagnosed or unreported.Ĭompared with STEC O157 infections, identification of non-O157 STEC infections is more complex. coli serogroups in the STEC group, including E. coli O157, many other kinds (called serogroups) of STEC cause disease. coli” infections, they are usually talking about E. When you hear news reports about outbreaks of “ E. The most commonly identified STEC in North America is E. coli O104:H4 that caused a large outbreak in Europe in 2011 was frequently referred to as EHEC. coli (EHEC) these all refer generally to the same group of bacteria. You might hear these bacteria called verocytotoxic E. The bacteria that make these toxins are called “Shiga toxin-producing” E. coli cause disease by making a toxin called Shiga toxin. This pathotype is the one most commonly heard about in the news in association with foodborne outbreaks. coli (STEC)-STEC may also be referred to as Verocytotoxin-producing E. Six pathotypes are associated with diarrhea and collectively are referred to as diarrheagenic E. coli strains are categorized into pathotypes. coli consists of a diverse group of bacteria. coli that can cause diarrhea can be transmitted through contaminated water or food, or through contact with animals or persons.Į. coli are pathogenic, meaning they can cause illness, either diarrhea or illness outside of the intestinal tract. coli are harmless and actually are an important part of a healthy human intestinal tract. coli) bacteria normally live in the intestines of people and animals.
