The Louisiana Department of Health and Hospitals on Wednesday reconfirmed that the Naegleria fowleri amoeba is present in the St. Bernard Parish water system.

After last week’s positive sample results at two sites, DHH resampled water in the area near the main initial positive finding. All three follow-up samples tested positive for Naegleria fowleri, a potentially dangerous brain-eating amoeba.

The parish’s water system is currently under a 60-day chlorine burn to ensure that any remaining amoeba in the system are eliminated.

“The tests from today were confirmatory,” State Health Officer Dr. Jimmy Guidry said.

Water samples were collected at 948 Angela St., 701 Lebeau St. and 318 Pontabol in St. Bernard Parish.

After the initial positive finding on Angela Street, Parish President David Peralta had suggested that faulty equipment was to blame.

Tap water in St. Bernard Parish is still safe for residents to drink, but residents are advised to avoid getting water in their noses.

Naegleria fowleri is an amoeba that occurs naturally in freshwater. It is dangerous only when water is pushed up the nose and into the brain.
