Officials say the brain-eating amoeba found in a west Ascension Parish water system this summer has been eradicated.
The announcement follows weeks of treatment involving pumping increased amounts of chlorine into water lines outside Donaldsonville.
State health officials say water with the amoeba has been safe to drink. However, water containing the amoeba poses a risk if it gets up someone’s nose and the amoeba has access to the brain.
Since 2011, three deaths in Louisiana have been attributed to the harmful strain of amoeba, prompting the Department of Health and Hospitals to order the state’s water systems to raise their chlorination levels.
