Blue-Green Algae Closes 2 Swimming Areas

Swimming areas at two Connecticut state parks are closed because blue-green algae was discovered.

The two swimming areas are at Indian Well State Park in Shelton and Kettletown State Park in Southbury.

Blue-green algae, which is also known as cyanobacteria, occurs naturally in lakes and ponds throughout the state. While the microscopic organisms cause no harm, blue-green algae blooms can release toxins and people and animals using the water for recreation can be affected.

Possible effects can include irritation of the skin, nose, eyes and respiratory tract; gastrointestinal upset, such as vomiting or diarrhea upon ingestion; and liver or nervous system effects if you ingest large amounts of the algae.

Dogs are especially at risk from exposure to blue-green algae blooms.

Earlier this summer, DEEP Commissioner Robert Klee said the issue of blue-green algae is not new, but there is now more research and "understanding on the toxic effects of these blooms and the public health concerns that they raise."
