At least 3 people have died from eating Death Cap mushrooms as they spread in California after rains

SAN DIEGO (AP) — At least three people have died and three others have required liver transplants after eating the aptly named Death Cap mushroom that is proliferating in California following a rainy winter.

The California Department of Public Health is urging people to avoid mushroom foraging altogether this year because Death Cap mushrooms are easily confused with safe, edible varieties.

Since Nov. 18 there have been at least three dozen cases of mushroom poisonings reported, according to the health department. Many who sought medical attention suffered from rapidly evolving acute liver injury and liver failure. Several patients required admission to an intensive care unit. They have ranged in age from 19 months to 67 years old.

“This greatly exceeds the typical report of less than 5 cases of mushroom poisonings a year,” the department said in its public health warning.

Experts warn that a mushroom’s color is not a reliable way of detecting its toxicity, and whether the Death Cap variety is raw, dried or cooked, does not make a difference.

Laura Marcelino told the San Francisco Chronicle that her family in the Northern California town of Salinas gathered mushrooms that looked like the ones she and her husband used to forage in their native Oaxaca, a state in Southern Mexico.

“We thought it was safe,” Marcelino, 36, said in Spanish.

Her husband was dizzy and tired the next day, but Marcelino felt fine, and they ate the mushrooms again, heating them up in a soup with tortillas. Their kids don’t like mushrooms and so didn’t have any. The next day, both adults, seasonal farmworkers, became ill with vomiting and stayed home from work.

Marcelino spent five days in the hospital, while her husband had to undergo a liver transplant.

People can have stomach cramping, nausea, diarrhea or vomiting within 24 hours after ingesting a toxic mushroom and the situation can quickly deteriorate after that, experts say. Early symptoms may also go away within a day, but serious to fatal liver damage can still develop within 2 to 3 days.

Death Cap mushrooms have been collected in local and national parks across Northern California and the Central Coast. Clusters have been identified in the Monterey and San Francisco Bay areas as well.

The public health department said those poisoned have included many Spanish, Mixteco, and Mandarin Chinese speakers and the state in response has expanded their warnings in different languages.

Children have been among those poisoned this year. Officials advise keeping an eye on children and pets outside where mushrooms grow, and buying mushrooms from trusted grocery stores and sellers.

Treatment is more difficult once symptoms start so doctors advise people to seek medical care once someone becomes aware that they have eaten a poisonous mushroom or suspect they have.

Craig Smollin, medical director for the San Francisco division of the California Poison Control System (CPCS) and an emergency medicine professor at the University of California, San Francisco Medical Center, said that death cap mushrooms tend to flourish between November and March in the state, though not usually to this extent.
