Welcome to the Verocytotoxigenic Escherichia coli (VTEC) Resource Centre hosted by the Irish Microbial Risk Assessment Network. The resource is divided into several sections as outlined below:


What is Verocytotoxigenic Escherichia coli (VTEC)?

VTEC is a particular group of the bacterium Escherichia coli. Although most strains of E. coli are harmless and live in the intestines of healthy humans and animals, VTEC strains produce a powerful toxin and can cause severe illness. In Ireland, the most common member of this group of bacteria is E. coli O157:H7, followed by E. coli O26. Other serogroups commonly linked to human illness in Europe include, O103, O145, O111 and O91. (Food Safety Authority of Ireland)
