Dangers of Harmful Algal Blooms in New York Water Bodies: Protect Your Health and Pets

Health officials across the state are urging swimmers and boaters to be cautious of Harmful Algal Blooms (HAB) in lakes, ponds, and streams. These blooms can pose a threat to both humans and pets, causing symptoms like diarrhea, nausea, vomiting, or throat irritation. Officials have issued an advisory for Conesus Lake in Livingston County that remains in effect. Despite this, the public water supply is safe for drinking.

HABs are composed of cyanobacteria, also known as blue-green algae, which are naturally present in aquatic systems. These blooms can turn the water green and form a thick scum on the water’s surface. Some HABs may produce toxins that can be harmful to both humans and animals. New York state tracks reports of harmful algal blooms on the Department of Environmental Conservation (DEC) website. Factors contributing to the formation of HABs include certain nutrients in the water, warm temperatures, and calm winds. Efforts have been made to control the outbreaks of HABs by reducing phosphorous and nitrogen runoff from farms and sewer systems into bodies of water.
