May 20, 2025 — On May 9, the California Department of Fish and Wildlife (CDFW) announced an immediate restriction on the commercial and recreational harvest of Pacific sardines for human consumption in ocean waters south of Point Conception to the California-Mexico border.
The move follows a public health warning issued after dangerously high levels of domoic acid were detected in sardine samples from the region.
The directive, issued by CDFW Director Charlton Bonham, was prompted by recommendations from the Office of Environmental Health Hazard Assessment (OEHHA) and the California Department of Public Health (CDPH). According to CDFW, sardines caught in the Southern California Bight pose “a human health risk due to elevated levels of domoic acid,” a naturally occurring marine toxin produced by harmful algal blooms.
