SACRAMENTO REGION, CA (MPG) - Recent rain has contributed to widespread growth of Death Cap mushrooms in California. Sacramento County Public Health (SCPH), in alignment with the California Department of Public Health (CDPH), is urging residents not to pick or eat wild mushrooms as the risk of potentially deadly amatoxin poisoning is high. Since Death Cap (Amanita phalloides) and Western Destroying Angel (Amanita ocreata) are easily confused for safe-to-eat lookalike mushrooms, all mushroom foraging should be avoided.

Sacramento County Public Health confirms four cases of amatoxin poisoning in Sacramento County caused by people accidentally picking and eating Death Cap and/or Western Destroying Angel mushrooms.

This comes amidst a continuing statewide outbreak linked to the consumption of wild, foraged mushrooms. There’s been reports of severe liver damage in both children and adults, resulting in three adult deaths and three liver transplants statewide to date.

Between Nov. 18, 2025, and Jan. 6, 2026, the California Poison Control System (CPCS) has identified 35 hospitalized cases across Northern California and the Central Coast, spanning regions from Sonoma to San Luis Obispo. Affected individuals range in age from 19 months to 67 years and include family groups and individual cases.

Most cases are in the Monterey and San Francisco Bay Area, though Death Cap mushrooms can be found across the state, particularly adjacent to oaks, other hardwoods and some pines. Information provided by affected individuals indicates that mushrooms were collected from various locations, including county, city and park lands.

Sacramento County Public Health and Sacramento County Regional Parks remind residents that wild mushrooms can be poisonous even if they resemble edible varieties and remain toxic even after cooking, boiling, freezing or drying.

“We understand that people may not realize the risk of mushroom foraging right now, because these mushrooms can closely resemble edible types,” said Dr. Olivia Kasirye, Sacramento County Public Health Officer. “That’s why we’re urging residents to avoid wild mushroom foraging altogether and to seek immediate help if exposure is suspected.”

Sacramento County Public Health is coordinating with the California Department of Public Health and California Poison Control on case investigation, tracking and public outreach.

What Residents Can Do

Avoid picking and eating wild mushrooms during this high-risk season when Death Cap mushrooms are abundant. Death Cap mushrooms are still poisonous even after cooking, boiling, freezing or drying.

Purchase mushrooms from trusted grocery stores and retailers and exercise caution when buying mushrooms from street vendors.

Keep children and pets away from wild mushrooms.

Seek help immediately if you or someone you know has eaten a poisonous mushroom. Contact the CPCS hotline: 1-800-222-1222. Do not wait for symptoms to appear. Treatment is more difficult once symptoms start.

Initial symptoms, such as watery diarrhea, nausea, vomiting, abdominal pain, and dehydration can occur within 6 to 24 hours following ingestion of these toxic mushrooms and usually go away within a day. However, this brief improvement can be deceptive, as patients may still develop serious to fatal liver damage within 48 to 96 hours after eating the mushrooms.
