Deadly Mushroom Outbreak Claims Fourth Life in California
30 Jan
Summary
- Fourth wild mushroom poisoning death confirmed in California since November.
- Victims may mistake toxic mushrooms for edible varieties from their home countries.
- This could be the largest outbreak of wild mushroom poisoning in state history.

A Northern California man's death on January 27 in Contra Costa County marks the fourth fatality from a severe wild mushroom poisoning outbreak. The victim, a man in his 60s, is believed to have mistakenly consumed a toxic mushroom foraged from a regional park, possibly confusing it with an edible variety from his homeland.
State officials are calling this the largest outbreak of wild mushroom poisoning in California history, with 39 cases reported across ten counties since November. A significant portion of those affected, approximately 60 percent, primarily speak Spanish, suggesting immigrants are particularly vulnerable due to misidentification of toxic fungi resembling those safe in their native countries.
Death Cap mushrooms, known as the deadliest in the world, are frequently implicated in these poisonings. Even small amounts can cause severe liver and kidney damage, hallucinations, seizures, and death. Cooking or freezing does not neutralize the potent toxin. The rainy season, from October to April, fosters the growth of these dangerous mushrooms, often found near oak and pine trees in California's parks.
