Pacific Sardine Fishery Temporarily Restricted in Southern California Due to Elevated Domoic Acid Levels

State health agencies have detected elevated levels of domoic acid in Pacific sardine sampled off the Southern California coast. In response, the California Department of Fish and Wildlife (CDFW) has implemented a temporary restriction on the commercial and recreational take of Pacific sardine for human consumption in waters south of Point Conception (34° 27.000’ N. lat.) to the California/Mexico border.

Key Details:

  • Pacific sardine may still be taken for use as live bait in the commercial fishery.
  • Recreational anglers may continue using sardine as bait, but not for consumption.
  • This restriction does not apply to other finfish, including rockfish, halibut, white seabass, yellowtail, and tuna.

The restriction is a precautionary measure based on findings from state health agencies. Domoic acid is a naturally occurring neurotoxin produced by marine algae (Pseudo-nitzschia) and can accumulate in fish. While the fish may appear healthy, consumption at high levels can cause serious health effects in humans, including memory loss, seizures, and in rare cases, death.

CDFW, along with the California Department of Public Health (CDPH) and the Office of Environmental Health Hazard Assessment (OEHHA), will continue monitoring domoic acid levels to determine when it is safe to lift the restriction.

Health & Safety Tips:

  • When advisories are in place, always consume only cleaned, skinned fillets.
  • Avoid cooking methods that mix edible portions with internal organs or other tissues.
