CA Public Health Department issues recreational shellfish advisory for Santa Barbara County
SANTA BARBARA COUNTY, Calif. – The California Department of Public Health is issuing a recreational shellfish advisory for Santa Barbara County, due to domoic acid as a harmful chemical.
The material found in shellfish affected sea lions in the Central Coast earlier this month.
Below is a press release from the County on the order:
On August 8, 2024, the California Department of Public Health (CDPH) issued an Advisory “not to consume” sport / recreationally-harvested shellfish. Dangerous levels of domoic acid have been detected in mussels from Santa Barbara County.
Commercially harvested shellfish in restaurants, grocery stores, or from fish markets may be safely consumed. These are not included in the advisory because commercial harvesters in California are certified by CDPH and subject to strict testing requirements to ensure that all oysters, clams, mussels and scallops entering the marketplace are free of toxins.
This advisory is in addition to the Annual Mussel Quarantine designed to prevent paralytic shellfish poisoning (PSP) and domoic acid poisoning, also known as amnesic shellfish poisoning, in people who might otherwise consume harvested mussels that have not been tested. Both of these syndromes are from naturally occurring toxins linked to plankton consumed by shellfish, including mussels and clams. Cooking does not destroy the toxins.
Early symptoms of PSP include tingling of the lips and tongue, which may begin within minutes of eating toxic shellfish. These symptoms are typically followed by a loss of balance, lack of muscular coordination, slurred speech and difficulty swallowing. In severe poisonings, a person may experience trouble breathing, confusion and disorientation, and medical attention should be sought immediately.
To minimize potential health risks, sport harvesters should not eat bivalve shellfish that are recreationally harvested during the summer months until the quarantine is lifted.
More information about the quarantine, PSP and domoic acid can be found on the CDPH Annual Mussel Quarantine - Frequently Asked Questions (FAQ) Web page. For updated information on quarantines and shellfish toxins, call the CDPH Biotoxin Information Line at (800) 553-4133.
