Last week, Louisiana's Department of Health and Hospitals issued a warning to residents: Don't use tap water to rinse your nasal passages.
The warning came after a 51-year-old woman in the state died after she was infected with the "brain-eating" amoeba Naegleria fowleri, which enters the body through the nose and sometimes causes devastating meningitis. Apparently, the amoeba lurked in tap water the woman used in her neti pot, a pitcher-like device used to rinse nasal passages. http://www.latimes.com/health/boostershots/la-heb-neti-pot-amoeba-20111220,0,6460552.story
