Fleets Cove Beach in Huntington Bay has been closed to swimming, as water samples show higher than acceptable levels of bacteria, Suffolk County health officials said Wednesday.

The beach will be reopened when testing shows that bacteria levels are at acceptable ranges, officials said.

Lake Ronkonkoma, closed on August 24 for the same reason, remains closed to swimming.
