The Director of the California Department of Fish and Wildlife (CDFW) has re-opened the recreational razor clam fishery in Del Norte County following a recommendation from state health agencies that domoic acid no longer poses a significant threat. While the razor clam fishery has reopened due to recent tests for domoic acid, the bivalve shellfish health advisory for Del Norte County issued by California Department of Public Health on July 3, 2025, warning consumers not to consume any sport-harvested bivalves (including razor clams, mussels, scallops, and clams, etc.) due to dangerous levels of paralytic shellfish poisoning (PSP) toxins remains in effect. The razor clam fishery remains closed in Humboldt County due to elevated levels of domoic acid.
