Shiga toxin-producing E. coli (STEC) are bacteria found in various livestock (cows, swine, etc) which can lead to dangerous food borne illness.Recent outbreaks in Europe are due to a specific type of STEC called strain 0104:h4. In the USA E. coli o157:h7 is a more common strain.Each produces a toxin (shiga) which can disrupt colon cells causing bloody diarrhea or destroy kidney cells & lead to HUS.
