STANTON, Neb. (AP) — Residents in the northeastern Nebraska town of Stanton have been told to boil their tap water.

The boil order was issued Thursday after testing of the municipal water system detected the presence of coliform and E. coli.

Stanton City Superintendent Ron Klinetobe says residents in Stanton should boil their water for at least one minute before consuming, or use another water source until testing shows no more contamination.

E. coli, a bacteria found in fecal matter, can be particularly dangerous to infants, young children, the elderly and those with compromised immune systems.
