Biotoxin Monitoring Program

Listed in NASA Earthdata CMR

Bivalve shellfish are highly sensitive to the quality of their marine environment.

Description

They feed on microscopic plants that can sometimes produce marine biotoxins, which can build up in their tissues. Eating shellfish with high levels of these biotoxins can lead to serious and potentially fatal illness.

Paralytic Shellfish Poisoning (PSP), as well as Amnesic Shellfish Poisoning (ASP) and Diarrhetic Shellfish Poisoning (DSP) are the most common human illnesses associated with marine biotoxins in Canada. Bacteria, viruses, metals and contaminants may also build up in the tissues of bivalve shellfish and cause food safety concerns for consumers. The Canadian Food Inspection Agency (CFIA) monitors shellfish harvesting areas to provide early warning of PSP toxins (and other toxins) in shellfish.

Hundreds of sites in Atlantic Canada, Quebec and British Columbia are regularly tested for PSP toxins. The Agency analyzes shellfish samples and, when levels are unacceptable, it notifies the Fisheries and Oceans Canada (DFO) which takes immediate action to close the affected area to shellfish harvesting. When areas are closed, signs are posted, media are notified, and DFO fishery officers patrol the areas to prevent the harvesting of shellfish.

With an area of 250,000 square kilometres, over 35 commercially harvested marine species and a great variety of fish in its rivers and estuaries, the Gulf of St. Lawrence constitutes one of the world's largest enclosed seas, a highly productive ecosystem, and a major arena of commercial fishing in Atlantic Canada. Waterbody or Watershed Names: Gulf of Saint Lawrence Sponsor: Canadian Food Inspection Agency Additional Information OR Comments: Fact sheets are available from the website.

Other information on closures and fishing maps are available at glf.dfo-mpo.gc.ca/os/aes-sae/dapr-radp/index-e.php?to_doE=refs&subject_cdE=6&rep_idE=r3 A file containing all pertinent sanitary survey information, including the dates and results of preceding surveys and reports is maintained by the shellfish control agency for each classified shellfish area.
