About STEC
Shiga toxin-producing Escherichia coli (STEC) are a group of bacteria that make Shiga toxins in the gut. These toxins can cause bloody diarrhoea.
Less commonly, STEC leads to HUS, a life-threatening condition that damages red blood cells and the kidneys. HUS can also be caused by other illnesses such as shigellosis, and some medications.
STEC most often spreads through contaminated food.
