Four more beaches were closed in Suffolk, almost doubling the number where swimming has been barred due to high levels of bacteria, county health officials said Friday.

The four newly closed beaches are: Knollwood Beach Association, Fleets Cove Beach, Huntington Beach Community Association, and Centerport Yacht Club.

Three were closed earlier: Lake Ronkonkoma’s Islip Town Beach, Valley Grove Beach in Eatons Neck and Venetian Shores Beach in Lindenhurst.

In a statement, county Commissioner of Health Dr. James Tomarken, warned that bathing in bacteria-contaminated water can cause gastrointestinal illness and infections of the eyes, ears, nose and throat.

The beaches will reopen after tests determine the amount of bacteria has declined to levels deemed safe, officials said.
