The statewide annual quarantine on sport-harvested mussels along the California coast ended Oct. 31, according to the California Department of Public Health.

“Sport-harvested” refers to seafood gathered for personal use rather than commercial sale.

The quarantine typically runs from May 1 to Oct. 31 to protect the public from shellfish poisoning.

During this period, the risk of paralytic shellfish toxins and domoic acid is higher; both are harmful when consumed.

There were no confirmed reports of related poisonings in the state during this period.

Warnings for sport-harvested razor clams in Humboldt County remain in effect.

Another warning for shellfish in the Northern Channel Islands—including mussels, clams, scallops and oysters—also remains in effect due to domoic acid concerns.
