Workshop: Cyanotoxins in New Hampshire Lakes

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.

NHDES 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. Dr. Tracie Caller, of DHMC, will review and discuss the research study that DHMC is currently conducting to determine if there is a possible link between cyanobacteria and sporadic amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig’s disease.

The workshop is free and open to the public, but pre-registration is required as the capacity of the workshop is limited to 140 attendees.

Cyanobacteria are among the earliest inhabitants of our waters and they naturally occur in lakes around the world. Research indicates that their abundance increases as the nutrients in a lake increase. Some cyanobacteria produce toxins that adversely affect livestock, domestic animals, and humans. During the summers of 1999 and 2000, several dogs died after ingesting toxic cyanobacteria from blooms in Lake Champlain in Vermont. Generally, the water quality of New Hampshire’s lakes is very good, however, cyanobacteria do exist in New Hampshire 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.
