Expansive areas of photosynthesizing bluish-green cyanobacteria in lakes are called blooms. These blooms can contain toxins that can be harmful to both human and other animals’ health. A variety of state, local, and regional organizations are engaged in efforts to monitor for the presence of blooms and to alert the public when they are present.

Lake Champlain Sea Grant’s focus has been to educate the public about how to keep humans and dogs safe from cyanobacteria toxins. A short video is available below to help people understand how to recognize cyanobacteria blooms, health concerns that result from exposure, and how to keep your dog safe if it is exposed to a bloom.
