Enterotoxigenic E. coli (ETEC) is one of the most common causes of diarrhea for travellers to many parts of the world. ETEC produces two toxins: a heat-stable toxin (ST) and/or a heat-labile toxin (LT).
If you eat food or drink water or ice that is contaminated with LT-ETEC, you are at risk of getting LT-ETEC diarrhea.
