Naegleria fowleri in Louisiana Public Water Systems

The Department of Health and Hospitals (DHH) in Louisiana and CDC confirmed the presence of Naegleria fowleri in two treated public drinking water systems in September-October 2013. A child staying in St. Bernard Parish died from infection with Naegleria fowleri, and the ameba was found in the plumbing system of the home and in the treated drinking water system 1. The ameba was also found in the treated drinking water system in DeSoto Parish. In 2011, both parishes had a death associated with neti pot use 2.
