A beach in Suffolk County was closed to swimming Monday due to higher-than-acceptable bacteria levels, and another that had been closed last week for that reason was reopened, county health officials said.

Tanner Park Beach in Copiague is closed to swimming because of bacteria levels exceeding state standards, with the closure lifted for Great Pond Beach at Peconic Dunes Camp in Southold, as samples show water quality to be acceptable, officials said.

Swimming in such contaminated water "can result in gastrointestinal illness, as well as infections of the eyes, ears, nose and throat," said Dr. James Tomarken, county health commissioner.
