Blue-green algae prompts closure of Hook Pond in East Hampton, says Suffolk

Because of the confirmed presence of blue-green algae, residents are asked not to use or swim in the waters of Hook Pond in the Town of East Hampton, Suffolk County health officials said Friday.

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

Similar precautions should be taken with other locations with blue-green algae -- Sagaponack Pond, Old Town Pond, Agawam Lake and Mill Pond, Southampton; Georgica Pond, East Hampton; Kellis Pond, Bridgehampton; Wainscott Pond, Wainscott; Maratooka Lake, Mattituck; Roth Pond, Stony Brook University; McKay Lake, Calverton; and Fort Pond, Montauk.

Any water looking "scummy or discolored should be avoided," 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.

Blue-green algae, also known as cyanobacteria, is naturally present in low numbers, but can increase, forming blooms of green, blue-green, yellow, brown or red, as well as floating scum, the county health department said in a release.
