What You Need to Know: CDPH is warning consumers not to eat any parts of sport-harvested Dungeness crab from portions of the Northern California Coast due to high levels of domoic acid.
SACRAMENTO –The California Department of Public Health (CDPH) is warning the public to not consume any parts of sport-harvested Dungeness crab (meat or viscera) caught from one of the coastal areas of northern California.
This warning is in effect for whole Dungeness crab harvested from the following state waters:
- Reading Rock State Marina Reserve (41° 17.6' N. Latitude) to Camp Mendocino (40⁰ 10.00' N. Latitude)
Dangerous levels of domoic acid, which can cause Amnesic Shellfish Poisoning, have been detected in the meat and viscera (internal organs) of Dungeness crab caught from the above coastal area of northern California.
This notification updates the
Whole Dungeness Crab Advisory dated October 24, 2025, where the public was warned to not consume any sport-harvested whole Dungeness crab (meat or viscera) from several coastal areas of northern California.
Domoic Acid is a naturally occurring biotoxin. Cooking the crab does not decrease or destroy the toxin. 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.
CDPH continues to coordinate its efforts with the California Department of Fish and Wildlife (CDFW) and the fishing community to collect and test crab samples from the impacted areas until domoic acid levels have dissipated. Please contact CDFW for information about the recreational Dungeness crab season.
Test results are updated as laboratory results become available and can be viewed on the
