Here’s one good reason to keep your mouth shut when you’re doing the backstroke at the lake: A strain of E. coli, known as Shiga toxin-producing E. coli or STEC.  STEC, which can cause symptoms like diarrhea, urinary tract infections, respiratory illnesses and even pneumonia, can infect swimmers who swallow contaminated water.
