The California Department of Public Health (CDPH) lifted the Shellfish Safety Notification today related to sport-harvested whole scallops and all clams in Santa Cruz County. The safety notification was issued due to dangerous levels of naturally occurring paralytic shellfish poisoning (PSP) toxins that can cause illness or death. Recent testing shows PSP toxins have decreased to safe or undetectable levels.
The annual mussel quarantine remains in effect. The annual quarantine applies to all species of mussels harvested along the California coast, as well as all bays and estuaries, and will continue through at least October 31.
This does not apply to commercially sold clams, mussels, scallops or oysters from approved sources. State law permits only state-certified commercial shellfish harvesters or dealers to sell these products. Shellfish sold by certified harvesters and dealers are subject to frequent mandatory testing to monitor for toxins.
PSP toxins affect the central nervous system, producing a tingling around the mouth and fingertips within a few minutes to a few hours after eating toxic shellfish. These symptoms are typically followed by loss of balance, lack of muscular coordination, slurred speech and difficulty swallowing. In severe poisonings, complete muscular paralysis and death from asphyxiation can occur.
