The annual California Department of Public Health (CDPH) warning against eating sport-harvested mussels along the state’s coast will take effect on May 1. This warning, which will remain in effect until at least October 31, advises consumers not to consume mussels harvested recreationally during the summer months.
The CDPH issued this warning to protect the public from paralytic shellfish poisoning (PSP) and domoic acid poisoning, both of which can be caused by naturally occurring toxins found in shellfish such as mussels and clams. These illnesses can cause symptoms like tingling of the lips and tongue, followed by more severe symptoms like loss of balance, slurred speech, and difficulty swallowing.
In severe cases, these illnesses can lead to trouble breathing, confusion, disorientation and require immediate medical attention. It’s important for individuals to avoid eating mussels harvested recreationally during the summer months to reduce health risks associated with these toxins. More information about the quarantine, PSP, and domoic acid poisoning can be found on the CDPH website. For updates on quarantines and shellfish toxins, individuals can call the CDPH Biotoxin Information Line at (800) 553-4133.
