Due to the confirmed presence of blue-green algae, residents are asked to steer clear of going into the waters of Lake Ronkonkoma off Pond Road in the Town of Brookhaven, Suffolk County health officials said Tuesday.
Pets and children should be kept away from the area, officials said. The algae has not been found at Lake Ronkonkoma Beach in the Town of Islip, which remains open for swimming, officials said.
Similar precautions should be taken with other locations with blue-green algae: Sagaponack Pond, Southampton; Georgica Pond, East Hampton; Roth Pond, Stony Brook University; McKay Lake, Calverton; Fort Pond, Montauk; Kellis Pond, Bridgehampton; Wainscott Pond, Wainscott; Agawam Lake and Mill Pond, Southampton; Maratooka Lake, Mattituck.
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; 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.
