(WHAM) - Blooms of blue green algae are being reported in parts of Canandaigua Lake and Honeoye Lake, according to the New York State Department of Health.

The algae, which can be toxic if ingested by humans or animals, was found in designated swimming areas of Butler Beach on Canandaigua Lake and Sandy Bottom Beach on Honeoye Lake. Both beaches are now closed for swimming.

Blue green algae forms in natural bodies of water during long stretches of hot weather, especially in shallow areas of water. The algae can produce toxins that can create health risks to people and animals if they are exposed in large enough quantities. Home boiling, disinfecting, and filtering do not kill algae toxins.

Symptoms can include allergic reactions or eye, skin, nose, and throat irritation. Liver and nervous system damage may occur if large amounts of water containing blue green algae are consumed.

If you or someone you know comes into contact with blue green algae, they should wash the affected area with soap and water and rinse thoroughly with clean water.
