Three beaches in Suffolk have been closed to bathing due to high bacteria levels, but one beach was cleared for swimmers, the county health department said Thursday.

Steers Beach in Northport, Prices Bend Beach in Eatons Neck and West Oaks Recreation Club Beach in West Sayville are off limits until water samples show acceptable levels of bacteria, officials said.
