Contra Costa County Man Latest to Die From California Toxic Wild Mushroom Outbreak

At least 39 poisonings and four deaths have been reported amid California's ongoing deadly Death Cap mushroom outbreak, officials said.

  • On Tuesday, Contra Costa Health confirmed a Contra Costa County resident in his 60s died after eating wild mushrooms foraged in a regional park.
  • Because poisonous species mimic edible ones, the California Department of Public Health says the state faces an "unprecedented" outbreak linked to Death Cap and Western Destroying Angel mushrooms that appear in the rainy season.
  • Symptoms typically appear within 6 to 24 hours and even mild nausea can signal serious reactions, while hospitalizations have occurred across Alameda, Contra Costa, San Francisco, San Mateo, Santa Clara, Sonoma, Monterey, San Luis Obispo, and Santa Cruz counties.
  • The East Bay Regional Park District prohibits mushroom collecting and health officials urge anyone exposed to poisonous mushrooms to seek care immediately or call the California Poison Control Hotline at 1-800-222-1222.
  • Between Nov. 18 and Jan. 18, at least 39 cases and four deaths were reported, with patients aged 19 months to 67 years; agency spokesperson George Barahona said some mistook toxic mushrooms for edible ones.
