SACRAMENTO  

The California Department of Public Health (CDPH) is warning consumers not to eat certain types of seafood from the Ventura county coastline due to dangerous levels of a naturally occurring toxin that can cause illness or death.
Consumers are advised not to eat:
  • recreationally harvested bivalve shellfish (such as mussels, clams or whole scallops), or
  • the internal organs of lobster or rock crab

Dangerous levels of domoic acid have been detected in the internal organs of lobster (also called lobster tomalley) from this region. This toxin, also known as Amnesic Shellfish Poisoning (ASP), can cause illness or death in humans. No cases of human poisoning from domoic acid are known to have occurred in California. Rock crab are also capable of accumulating this toxin in the internal organs (also called crab butter).

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.

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. 

The annual quarantine on recreationally harvested mussels remains in effect along the entire California coastline. This quarantine applies to all species of mussels harvested along the California coast, including all bays and estuaries.
