Cyanotoxins are produced by some cyanobacteria (also known as blue-green algae). Cyanobacteria naturally occur in lakes across New Hampshire, the United States and the world. Cyanotoxins can adversely affect livestock, domestic animals, and humans when present in large amounts. A cyanobacteria bloom may turn the water a bright green (pea-soup) or bluish-green color and/or produce septic or grassy odor. During the summer of 1999, several dogs died after ingesting toxic cyanobacteria from a bloom in Lake Champlain in Vermont. Generally, the water quality of New Hampshire’s lakes is very good; however cyanobacteria can even be found in New Hampshire’s low nutrients waters. Exposure to toxic cyanobacteria scums may cause various symptoms, including nausea, vomiting, diarrhea, mild fever, skin rashes, eye and nose irritations, and general malaise. If you would like to learn more about cyanotoxins, please attend this workshop.
