"Cyanotoxins in New Hampshire Lakes – What you Need to Know"
Workshop July 1 in Concord

Concord, NH – The New Hampshire Department of Environmental Services, the UNH Center for Freshwater Biology, and the Dartmouth Hitchcock Medical Center (DHMC) will present at a Workshop "Cyanotoxins in New Hampshire Lakes – What You Need to Know" on Wednesday, July 1, 9:00 a.m. to 12:45 p.m. at the Department of Environmental Services, 29 Hazen Drive, Concord, N.H.

DES and UNH staff will explain what cyanotoxins are, where and why they exist in lakes and ponds here and around the world; the public health impacts and potential dangers to pets and wildlife; what the State is doing to monitor the cyanotoxins; and what you need to know and do if you or your pet are exposed to a bloom. A Dartmouth scientist researching the possible link between cyanobacteria and sporadic amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig’s disease will review and discuss the study that DHMC is currently conducting.

The workshop is free and is open to the public, but limited to 140 attendees. Please register on-line to ensure a seat:

Cyanotoxins are produced by some cyanobacteria. Cyanobacteria naturally occur in lakes across New Hampshire, throughout 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.
