Mussel Quarantine Announced
CDPH Warns Consumers Not to Eat Sport-Harvested Bivalve Shellfish from Monterey County
The California Department of Public Health (CDPH) is advising consumers not to eat recreationally harvested mussels, clams or whole scallops from Monterey County. Dangerous levels of paralytic shellfish poisoning (PSP) toxins have been detected in mussels from this region. The naturally occurring PSP toxins can cause illness or death in humans. Cooking does not destroy the toxin.
This warning 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. There have been no reports of illnesses related to this event.
The most current information on shellfish advisories and quarantines is available by calling CDPH’s toll-free Shellfish Information Line at (800) 553-4133. For additional information, please visit the CDPH Marine Biotoxin Monitoring Web page.
PINTO & KELLY LAKES ADVISORY
Pinto and Kelly Lakes are subject to blooms of blue-green algae (cyanobacteria). Cyanobacters such as microcystis are known to produce toxins, exposure to which can cause rashes, skin and eye irritation, allergic reactions, gastrointestinal upset, and other effects. At high levels, exposure can result in serious illness or death. Exposure may occur by ingestion, dermal contact or inhalation. Avoid body contact with blue-green algal blooms. This includes swimming, wading and water-skiing. Also do not allow your pets to enter the water. For more information visit the California Department of Public Health here.
The most recent sample results, taken 04 January, 2017, by the City of Watsonville, detected no microcystins toxin at the City of Watsonville boat launch ramp at Pinto Lake (detection limit is 1 part per billion [ppb]).
