Because of the confirmed presence of blue-green algae, residents are asked to steer clear of using the waters of Mill Pond in Southampton, Suffolk County health officials said Friday.

Pets and children should also be kept away from the area, officials said.

Any water looking “scummy or discolored should be avoided,” health officials said. If contact does occur, rinse off with clean water and see a doctor for symptoms that can include nausea, vomiting or diarrhea; skin, eye or throat irritation; and allergic reactions or breathing difficulties, the health department said.
