Cayuga County warns of harmful algal blooms on Cayuga Lake

In a public health advisory issued July 15, the Cayuga County Health Department has joined other officials in the region warning the public that HABs can produce toxins dangerous to both humans and animals. The blooms appear as green, blue-green, yellow, brown, or red paint-like streaks or floating mats on the water.


“HABs can cause negative health effects in both people and animals,” the advisory stated. “People, pets, and livestock should avoid all contact with water that is discolored or has floating mats or scum on the surface.”

Officials are warning the public not to swim, fish, or wade in any water suspected of containing HABs. If contact occurs, it is advised to rinse thoroughly with clean water. Residents using private water systems are also advised not to use untreated lake water for drinking, cooking, or bathing during a bloom.

Suspected blooms can be reported to the New York State Department of Environmental Conservation at on.ny.gov/habform or via email at [email protected].

Anyone experiencing symptoms such as nausea, vomiting, diarrhea, skin irritation, or respiratory issues after exposure should contact a healthcare provider or veterinarian.

Because HABs are common during warmer months, the county will not issue a separate release for each new occurrence. Beachgoers are encouraged to contact local beach operators before heading out to ensure the area is safe for swimming.
