The California Department of Public Health has issued its annual shellfish safety warning, which will take effect on May 1 and remain in effect until at least October 31. This warning advises consumers not to eat sport-harvested mussels along the California coast, as they may contain toxins that can cause serious illness.
Commercially harvested shellfish are exempt from this warning because they undergo strict testing requirements to ensure they are safe for consumption. Therefore, mussels available for commercial consumption are safe to eat. However, it is important for consumers to be aware of the potential dangers of eating shellfish during this time period and follow the guidelines provided by health officials.
The annual mussel warning is aimed at preventing paralytic shellfish poisoning (PSP) and domoic acid poisoning, also known as amnesic shellfish poisoning. These illnesses are caused by naturally occurring toxins that can be present in shellfish such as mussels and clams. Cooking does not eliminate these toxins, and early symptoms of poisoning can include tingling of the lips and tongue followed by more severe symptoms like loss of balance, slurred speech, and difficulty swallowing.
In severe cases, poisoning can lead to trouble breathing, confusion, disorientation requiring immediate medical attention. To reduce health risks, sport harvesters are advised to avoid eating recreationally harvested mussels during the summer months starting on May 1. More information about the quarantine, PSP and domoic acid poisoning can be found on the CDPH website or by calling the CDPH Biotoxin Information Line at (800) 553-4133. It is important for consumers to follow these guidelines and prioritize their health while enjoying seafood during this time period.
