What is STEC?
STEC is an acronym for Shiga toxin-producing Escherichia coli. Most E. coli bacteria are normal inhabitants of the intestinal tracts of humans and animals, and are non-pathogenic (do not cause disease).
Human outbreaks of STEC-related disease occur through consumption of contaminated food or water, through direct contact with infected animals or environments contaminated by their feces, or by direct human-to-human contact with infected persons (i.e. secondary infections). Cattle and other ruminant animals such as deer are natural reservoirs of STEC, which can lead to contamination of meat and milk during harvest and processing.
