The California Department of Public Health (CDPH) lifted health advisories on June 2 related to certain sport-harvested bivalve shellfish in Del Norte and Marin counties.

For Del Norte County, the advisory is being lifted for whole scallops and clam species other than razor clams. For Marin County, the advisory is being lifted for whole scallops and all clams. The health advisories were issued due to elevated levels of paralytic shellfish poisoning (PSP) toxins. Recent tests show that PSP toxins have decreased to safe or undetectable levels. There have been no reported illnesses associated with these PSP events. The CDPH warning against eating sport-harvested razor clams from Del Norte and Humboldt counties due to dangerous levels of another toxin, domoic acid, remains in effect, as does the statewide annual quarantine on sport-harvested mussels.
