The California Department of Public Health (CDPH) has issued a warning after an outbreak of amatoxin poisoning was linked to eating wild, foraged mushrooms. According to the California Poison Control System, there have been 21 reported cases as of December 5, 2025. The cases include both children and adults, with severe liver damage reported and one adult death. Most cases have occurred in the Monterey and San Francisco Bay Areas, but health officials say the risk is present throughout the state.
Dr. Erica Pan, CDPH Director and State Public Health Officer, said: “Death cap mushrooms contain potentially deadly toxins that can lead to liver failure. Because the death cap can easily be mistaken for edible safe mushrooms, we advise the public not to forage for wild mushrooms at all during this high-risk season.”
Amatoxin poisoning is often associated with the death cap mushroom (Amanita phalloides), which is known for its toxicity and resemblance to edible varieties. CDPH recommends that individuals avoid collecting or consuming any wild mushrooms due to the current heightened risk.
