Overview
- Health officials in Napa County reported that three adults were hospitalized after foraging in the Deer Park area over the weekend.
- California has logged 47 severe poisonings and four deaths since Nov. 18, 2025, with at least three patients needing liver transplants.
- The cases are tied to death cap and western destroying angel mushrooms, which contain amatoxins that can quietly damage the liver after a 6–24 hour lull.
- Recent rains have spurred new growth of these look‑alike mushrooms, with spring cases added in counties such as Napa and Monterey.
- Officials urge people not to eat wild mushrooms, to keep kids and pets away, and to seek immediate care and call 1-800-222-1222 if exposure is suspected because cooking does not remove the toxin.
