CALIFORNIA: Recreational crab season opens along the Sonoma Coast as state warns of biotoxin risk

November 3, 2025 — There’s a catch to this year’s crab season and it’s not just in the traps.

The recreational Dungeness crab season opened Saturday along the Sonoma Coast, but state officials are warning fishers about potentially dangerous levels of domoic acid in the crabs’ internal organs.

In a health advisory issued Oct. 24, the California Department of Fish and Wildlife and the California Department of Public Health said unhealthy levels of the naturally occurring toxin have been found in the viscera, or the internal organs of the crab. Officials warned that cooking the crab does not destroy the toxin, advising fishers to not ingest any part of the viscera.

Domoic acid poisoning in humans can cause nausea, dizziness and in severe cases, even memory loss or death, public health officials cautioned.

Despite the warnings, recreational crabbers can still hit the seas, unlike Bodega Bay’s Dick Ogg and other commercial fisherman who have been sidelined following seven straight years of season delays to protect endangered marine life from entanglements.

For Ogg, who predicts the commercial season will once again not open until January, and other fishermen across the state, these delays take a major toll on their profit margins.

“The impact is significant,” Ogg said Saturday. “What we have lost is our Thanksgiving, Christmas and New Year’s crab market. Everything has been pushed ahead to when people are less interested in getting the resource. It’s a lot more difficult and the financial impact to everyone is pretty significant.”

US importers recall Korean oysters due to possible norovirus contamination

July 24, 2025 — Two U.S. importers have recalled frozen half-shell oysters from South Korea due to possible contamination with norovirus.

Vernon, California, U.S.A.-based Wang Globalnet recalled 1,200 cases of frozen half-shell oysters labeled “Product of Korea, Pack 144 counts,” with a harvest date of 12 January. This came after the California Department of Public Health notified the company about multiple reported illnesses stemming from the product in the state of Utah, Wang Globalnet said.

CALIFORNIA: California removes limits on sardine fishing after domoic acid concerns pass

June 16, 2025 — The California Department of Fish and Wildlife (CDFW) has removed limits on sardine fishing in Southern California, declaring the fish once again safe for human consumption.

The state had initially limited sardine fishing from Point Conception south to the Mexico border after the Office of Environmental Health Hazard Assessment (OEHHA) and the State Public Health Officer at the California Department of Public Health (CDPH) determined that elevated levels of domoic acid in sardines posed a risk to human health. Domoic acid, which is a naturally occurring neurotoxin emitted by marine algae, can accumulate in fish and cause several health issues, even proving fatal in some cases, for humans.

CALIFORNIA: The secret Richmond lab where Bay Area crab season annually learns its fate

November 29, 2019 — Each year, the fate of Northern California’s Dungeness crab season is in the hands of a few scientists in a quiet East Bay lab examining a small container of tan goo.

At the California Department of Public Health lab in Richmond, the goo is viscera, or the internal organs of a Dungeness crab, and the scientists study it to determine whether a neurotoxin called domoic acid is present.

While the commercial Dungeness crab season is on hold for an entirely different reason — a lawsuit over whale entanglements that postponed the season until Dec. 15 — three of the last four commercial Dungeness crab seasons were delayed after domoic acid, which is poisonous to humans, was found in local crustaceans. The neurotoxin can become present in crabs when algal blooms caused by rising ocean temperatures linger in local fishing waters during crab season. And with California crab fishermen capable of grossing $95 million a year during an uninterrupted season, domoic acid has resulted in tens of millions of dollars in lost revenue.

California: Surprise Drop in Domoic Acid Levels in N. California Mean Fisheries Are Clear; Oregon to Retest Also

January 3, 2018 — SEAFOOD NEWS — Late Friday, before New Year’s weekend, California state agencies released welcome news: recent testing showed a commercial lobster area could be opened and an advisory lifted for sport crabbing north of the Klamath River in northern California.

State agencies have been testing for domoic acid, a naturally occurring neurotoxin, routinely in the fall and winter in anticipation of opening closed lobster areas and lifting crabbing advisory for sport fishermen or opening the commercial crab season.

On Friday, the California Department of Fish and Wildlife Director Charlton H. Bonham lifted the commercial spiny lobster fishery closure on the southeast side of Santa Cruz Island east of 119°40.000’ W. longitude, west of 119° 30.00’ W, and south of 34°00.000’ N. latitude as recommended by state health agencies, the state notice said. According to the notice from the Director of the Office of Environmental Health Hazard Assessment, sampling of spiny lobster and analysis of samples by California Department of Public Health laboratories indicates that consumption of spiny lobster taken from this area no longer poses a significant threat for domoic acid exposure, it continued.

On Oct. 24, 2017, state health agencies determined that spiny lobster in waters around Anacapa Island, Ventura County and the east end of Santa Cruz Island, Santa Barbara County had unhealthy levels of domoic acid and recommended closure of the commercial fishery in this area.

The commercial closure remains in effect in all state waters around the northeast end of Santa Cruz Island east of 119°40.000’ W. longitude, west of 119° 30.00’ W, and north of 34°00.000’ N. latitude and the south side of Anacapa Island east of 119°30.000’ W, west of 119°20.000’ W, and south of 34°00.000’ N latitude. The closures will remain in effect until state agencies determine domoic acid no longer poses a significant risk to public health.

At the same time, CDPH lifted the last remaining health advisory for Dungeness crab caught along the California Coast in sport fisheries. CDPH lifted this advisory Friday due to recent tests showing that the amount of domoic acid has declined to low or undetectable levels in Dungeness crab caught in the area, indicating that they are safe to consume. The final health advisory lifted Friday was for Dungeness crab caught north of the Klamath River mouth, Del Norte County (41°32.500’ N. lat.) to the Oregon border.

The advisory lifting for the sport fishery gives commercial crabbers in Northern California they might be able to set gear on Jan. 15.

However, the second test in a row of clear crab from Pt. St. George Reef in northern California was a surprise to Oregon fishery managers who scrambled to get vessels out to harvest crab for testing in Southern Oregon. Without two clear tests in a row of domoic acid, at least seven days apart, Oregon managers will have to work with Tri-State managers to determine when and how to allow commercial fishing in southern Oregon and northern California.

Tri-State fishery managers already have announced a Jan. 15, 2018, commercial fishery opening north of Cape Blanco, near Port Orford, Oregon.

CALIFORNIA: Toxic algae delays Dungeness crab season

January 19, 2017 — As expected, the opening of the commercial fishing season for California’s treasured Dungeness crab will be later than usual.

The California Department of Fish and Wildlife on Friday evening announced that,  because of a toxic algal bloom that could be related to warm temperatures brought by El Niño, the start of the commercial season will be later than the traditional Nov. 15 date.

This follows the delay in the recreational fishery announced by the California Fish and Game Commission on Thursday, and a Wednesday afternoon announcement that the California Department of Public Health had recommended that people not eat any California-caught Dungeness or rock crab until further notice.

“Crab is an important part of California’s culture and economy, and I did not make this decision lightly,” said fish and wildlife agency director Charlton H. Bonham in a statement. “But doing everything we can to limit the risk to public health has to take precedence.”

According to a public health agency spokesman, the agency will continue collecting samples up and down the California coast on a weekly basis. “Once the levels of [the toxic algae] decline in the coastal waters, we usually start seeing the levels of domoic acid in bivalve shellfish (i.e., mussels and clams) and small finfish (i.e., anchovies and sardines) start to decline. Crustaceans such as Dungeness and rock crab are usually the last animals to flush the domoic acid out of their systems.”

California Seeks Federal Disaster Declarations for Commercial Crab Fishing

February 9, 2016 — In a letter to U.S. Secretary of Commerce Penny Pritzker, Gov. Edmund G. Brown Jr. today requested federal declarations of a fishery disaster and a commercial fishery failure in response to the continued presence of unsafe levels of domoic acid, a potent neurotoxin, in Dungeness and rock crab fisheries across California and the corresponding closures of those fisheries.

‘Crabs are a vital component of California’s natural resources and provide significant aesthetic, recreational, commercial, cultural and economic benefits to our state,’ Governor Brown said in the letter to Secretary Pritzker. ‘Economic assistance will be critical for the well-being of our fishing industry and our state.’

In early November 2015, the Office of Environmental Health Hazard Assessment (OEHHA), in consultation with the California Department of Public Health (CDPH), recommended a closure based on unsafe levels of domoic acid found in crab tissue that was likely to pose a human health risk. Domoic acid is a potent neurotoxin that can accumulate in shellfish and other invertebrates. At high levels, it can cause persistent short-term memory loss, seizures and death. At low levels, domoic acid can cause nausea, diarrhea and dizziness.

Crab season: Fishermen scrambling to pay bills

November 16, 2015 — This was supposed to be the winter Braeden Breton finally realized his dream of running his own crab fishing boat. After putting down $7,500 in April toward a commercial permit, he was counting on earning enough money as a deckhand this fall to pay off the rest and begin setting his own traps after the new year.

Now the indefinite postponement of the commercial Dungeness crab season has thrown that plan into disarray. Like hundreds of other fishermen in the Bay Area, Breton finds himself scrambling to pay the bills.

Breton, of El Granada, and a partner must make monthly payments on the $20,000 they still owe for the permit. He may head north this month in the hope of finding work on a boat in Oregon, where the Dungeness crab season is tentatively slated to open Dec. 1 on the northern half of the coast.

“It’s hard on everyone around me, and it’s hard on me as well,” Breton, 23, said of the delay. “I have to keep up with my payments or I’ll lose my permit.”

More than a week after the California Department of Fish and Wildlife shut down the commercial season because of high levels of neurotoxins in the crab, the outlook for California fishermen is as murky as the ocean depths where the prized crustaceans scuttle and scavenge.

Toxin Taints Crabs and Kills Sea Mammals, Scientists Warn

November 4, 2015 — The authorities in California are advising people to avoid consumption of crabs contaminated by a natural toxin that has spread throughout the marine ecosystem off the West Coast, killing sea mammals and poisoning various other species.

Kathi A. Lefebvre, the lead research biologist at the Wildlife Algal Toxin Research and Response Network, said on Wednesday that her organization had examined about 250 animals stranded on the West Coast and had found domoic acid, a toxic chemical produced by a species of algae, in 36 animals of several species.

“We’re seeing much higher contamination in the marine food web this year in this huge geographic expanse than in the past,” Ms. Lefebvre said.

She said that the toxin had never before been found in animals stranded in Washington or Oregon, and that there were most likely greater numbers of contaminated marine mammals not being found by humans.

The California Department of Public Health recently advised people to avoid consumption of certain species of crabs because of potential toxicity. Razor clam fisheries in Washington have been closed throughout the summer for the same reason.

In a statement released on Tuesday, the California department said that “recent test results” indicated dangerous levels of domoic acid in Dungeness and rock crabs caught in California waters between Oregon and Santa Barbara, Calif.
