A deadly brain-eating amoeba was discovered in the mains water supply of a Texas town.
Residents of Brazoria, Texas, and the surrounding area were banned from drinking or using tap water and only allowed to flush their toilets.
The amoeba, known as naegleria fowleri, prompted a health-warning from authorities on Friday which impacted 58,000 people.
Health experts say that the amoeba affects people when contaminated water enters the body through the nose.
