Escherichia coli (/ ˌ ɛ ʃ ə ˈ r ɪ k i ə ˈ k oʊ l aɪ /), also known as E. coli (/ ˌ iː ˈ k oʊ l aɪ /), is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms).
The bacteria constituting the species Escherichia coli are commonly found in the intestinal flora of man and animals, and were until late 1950s recognized as non-pathogenic normal cohabitants. However, certain strains might induce disease, and E. coli should therefore be regarded as a potential path …

Escherichia coli (E. coli) are mostly harmless bacteria that live in the intestines of people and animals and contribute to intestinal health. However, eating or drinking food or water contaminated with certain types of E. coli can cause mild to severe gastrointestinal illness. Some types of pathogenic (illness-causing) E. coli, such as Shiga toxin-producing E. coli (STEC), can be life-threatening. Different types of E. coli tend to contaminate different types of foods and water. Previous U.S. outbreaks of pathogenic E. colihave included leafy greens, sprouts, raw milk and cheeses, and raw beef and poultry. Some wildlife, livestock, and humans are occasional carriers of pathogenic E. coli and can contaminate meats and food crops. Ruminant animals such as cattle, goats, sheep, deer or elk, as well as other animals such as pigs or birds are known carriers of pathogenic E. coli, such as STEC, and are often the pathway as to how STEC is introduced into the environment.

FDA investigates outbreaks to control them, so more people do not get sick in the outbreak, and to learn how to prevent similar outbreaks from happening in the future. To stop the spread of outbreaks, the FDA, together with federal, state, and local partners, is increasingly using whole genome sequencing to track down sources of food contamination. Applying this technology to food safety, something pioneered by FDA and the GenomeTrakr network, helps public health investigators identify contaminated foods and figure out how the pathogens entered the food supply. Most recently, the FDA launched a new initiativewith support from the Arizona Department of Agriculture, and in conjunction with the University of Arizona Cooperative Extension, the Wellton-Mohawk Irrigation and Drainage District (WMIDD), and members of the Yuma area leafy greens industry to better understand the ecology of human pathogens in the environment in the Yuma agricultural region. This initiative will be a multi-yea...
Consumers who have symptoms of foodborne illnessshould contact their health care provider to report their symptoms and receive care. To report a complaint or adverse event (illness or serious allergic reaction), you have three choices: 1. Call an FDA Consumer Complaint Coordinatorif you wish to speak directly to a person about your problem. 2. Complete an electronic Voluntary MedWatch formonline. 3. Complete a paper Voluntary MedWatch formthat can be mailed to FDA.

Campylobacter is a helical-shaped, non-spore-forming, Gram-negative, microaerophilic, nonfermenting motile bacterium with a single flagellum at one or both poles, which are also oxidase-positive and grow optimally at 37 to 42 °C. When exposed to atmospheric oxygen, C. jejuni is able to change into a coccal form.
