Tainted shellfish led health officials to start California’s annual mussel quarantine nearly two weeks ahead of schedule.
The state Department of Health Services ordered the quarantine along the California coast Friday after higher-than-normal levels of domoic acid were detected in the shellfish.
The quarantine usually runs from May 1 to Oct. 31. It is aimed at preventing the deadly illnesses of paralytic shellfish poisoning and domoic acid poisoning.
The early quarantine was ordered after department scientists found tainted mussels during routine testing. Warning signs were posted near mussel and clam beds.
