Annual quarantine of sport-harvested mussels began early this year
The quarantine is in place to protect the public from shellfish poisoning
The annual quarantine of all sport-harvested mussel species along the California coast began April 22, 2013.
The annual mussel quarantine is for the prevention of paralytic shellfish poisoning (PSP) and domoic acid poisoning and is in effect as of April 22 because testing by the California Department of Public Health (CDPH) has detected elevated levels of domoic acid and high numbers of the algae that produce this toxin. Normally the quarantine runs from May 1 through October 31. This quarantine applies to all species of mussels harvested by the public anywhere on the California coast, including all bays and estuaries.
