The California Department of Public Health (CDPH) is advising consumers not to eat recreation-ally harvested mussels, clams or whole scallops from Del Norte County. Dangerous levels of Dominic acid have been detected in mussels from this region. This naturally occurring toxin is also referred to as Amnesic Shellfish Poisoning and can cause illness or death in humans.
Symptoms of domoic acid poisoning can occur within 30 minutes to 24 hours after eating toxic seafood. In mild cases, symptoms may include vomiting, diarrhea, abdominal cramps, headache and dizziness. These symptoms disappear within several days. In severe cases, the victim may experience trouble breathing, confusion, disorientation, cardiovascular instability, seizures, excessive bronchial secretions, permanent loss of short term memory, coma or death. No cases of human poisoning from domoic acid are known to have occurred in California.
