Enterohemorrhagic Escherichia coli (EHEC) infection is a bacterial illness of the gut caused by specific strains of *E. coli* that produce powerful toxins. Often referred to as Shiga toxin-producing *E. coli* (STEC), particularly O157:H7, it can affect people of all ages but is most severe in young children and the elderly. The infection is characterized by bloody diarrhea and can lead to a serious kidney complication called Hemolytic Uremic Syndrome (HUS).
