The mussel quarantine is a yearly event that happens due to dangerous levels of biotoxins that may be present in mussels gathered by the public anywhere on the California coast, including bays, inlets and harbors.  The quarantine applies only to sport-harvested mussels; commercially grown mussels from certified companies are not included in the quarantine.
