Razor Clam Fishery Closes in Del Norte County Resulting from Public Well being Hazard
The California Division of Fish and Wildlife (CDFW) Director Charlton H. Bonham has closed the recreational razor clam fishery in Del Norte County (PDF) following a recommendation from state health agencies (PDF) figuring out that consumption of razor clams within the space poses a major menace for domoic acid publicity.
Pseudo-nitzschia, a naturally occurring single-celled, marine alga, produces the potent neurotoxin domoic acid below sure ocean situations. Bivalve shellfish, like clams and mussels, accumulate the toxin with out being harmed. In actual fact, razor clams are recognized to bioaccumulate domoic acid, that means it might not clear their system till lengthy after a bloom has abated.
Sampling of razor clams from Crescent Seaside in Crescent Metropolis in late October discovered clams exceeding the present federal motion degree for domoic acid of higher than or equal to twenty elements per million.
Domoic acid poisoning in people could happen inside minutes to hours after consumption of affected seafood and can lead to indicators and signs starting from vomiting and diarrhea to everlasting lack of short-term reminiscence (Amnesic Shellfish Poisoning), coma or loss of life. There isn’t a strategy to put together clams for consumption that may take away the toxin – cooking and freezing don’t have any impact.
CDFW will proceed to work with the California Division of Public Well being (CDPH) and Workplace of Environmental Well being Hazard Evaluation to gather, monitor and analyze razor clams to find out when the leisure clam fishery in Del Norte County may be reopened safely.
