At least four dead from Death Cap mushrooms

SAN DIEGO>> Four people have died and three have required liver transplants after eating the aptly named death cap mushroom that is proliferating in California after a rainy winter.

The California Department of Public Health is urging people to avoid mushroom foraging 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 five 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.

People can have stomach cramping, nausea, diarrhea or vomiting within 24 hours after ingesting a toxic mushroom and the situation can deteriorate quickly after that, experts say. Early symptoms also may go away within a day, but serious to fatal liver damage can develop within two to three 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 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 and an emergency medicine professor at the University of California-San Francisco Medical Center, said Death Cap mushrooms tend to flourish between November and March in the state, although not usually to this extent.
