SACRAMENTO - The California Department of Public Health (CDPH) is advising consumers not to eat the viscera (internal organs) or roe of lobsters caught near Anacapa Island in Ventura County, due to the detection of dangerous levels of domoic acid, a naturally occurring toxin.

While domoic acid levels may vary, the viscera or roe usually contain much higher levels of domoic acid than the meat. Consumers should always follow these best preparation practices to avoid any inadvertent exposure to domoic acid that might be sporadically found in the lobster's viscera or roe. When whole lobsters are cooked in liquid, domoic acid may leach into the cooking liquid. Water or broth used to cook whole lobsters should be discarded and not used to prepare dishes such as sauces, broths, soups or stews (for example, cioppino or gumbo), stocks, roux, dressings or dips. Cooking lobsters neither decreases nor destroys the toxin, so consumers are advised to discard the viscera, roe, and cooking liquids.

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, cardiovascular instability, seizures, excessive bronchial secretions, permanent loss of short-term memory, coma or death.

CDPH continues to coordinate its efforts with the California Department of Fish and Wildlife (CDFW) and the fishing community to collect and test lobster samples from the impacted areas until domoic acid levels have dissipated. 

The Office of Environmental Health Hazard Assessment (OEHHA), in consultation with CDPH, has recommended a closure of the commercial lobster fishery around Anacapa Island in Ventura County. More information is available on the CDFW website.
