San Diego County public health officials are warning residents to avoid eating wild mushrooms due to a rise in amatoxin poisonings across California. - Since November 2025, 47 mushroom poisoning cases have been reported statewide, including 4 deaths and 4 liver transplants.
- Eight new cases have been reported in the last month as toxic mushrooms bloom in Southern California. - Symptoms appear 6-24 hours after consumption and include nausea, vomiting, abdominal pain, and diarrhea.
- Cooking, freezing, or drying does not destroy amatoxins. No cases have been reported in San Diego County yet, but officials urge caution and immediate medical attention if symptoms develop.
