Foodborne diseases are characterized by conditions that can induce symptomatic illnesses in their carriers, and therefore represent a serious problem. They are important conditions from a clinical and epidemiological point of view, and are associated with the occurrence of serious public health problems, with a strong impact on morbidity and mortality. The Escherichia coli ( E. coli ) is an enterobacterium associated with enteric conditions of variable intensity and which are accompanied by blood. The transmission routes are mainly based on the consumption of contaminated food and water sources. Shiga toxin-producing E. coli (STEC) are considered a serogroup of E. coli , are capable of producing Shiga-type toxins (Stx 1 and Stx 2) and the O157:H7 strain is one of the best-known serotypes. The early detection of this pathogen is very important, especially due to the capacity of contamination of carcasses destined for food consumption and supply of productive markets. Sanitary protocols must be developed and constantly reviewed in order to prevent/control the presence of the pathogen.
