The California Department of Public Health (CDPH) is advising consumers not to eat sport-harvested mussels, clams, or scallops from Humboldt and San Luis Obispo counties.
This shellfish safety notification is in addition to the annual mussel quarantine. The annual quarantine applies to all species of mussels harvested for human consumption along the California coast, as well as all bays and estuaries, and will continue through at least October 31.
