  • Three non-residents hospitalized after eating poisonous mushrooms in Napa Valley

Three adults were hospitalized after consuming poisonous wild mushrooms foraged in Napa County, California, according to health officials. The individuals ate mushrooms from the Deer Park area over the weekend, though they were not county residents.

The incident is part of a statewide outbreak that has seen 47 people fall seriously ill and four die since November, as reported by the California Department of Public Health. This surge in cases is unprecedented, with health officials linking it to an exceptionally wet December and April, which fostered the growth of toxic mushrooms. The majority of cases have been concentrated in Northern and Central California.

The poisonings are primarily associated with two lethal mushroom species: the death cap (Amanita phalloides) and western destroying angel (Amanita ocreata). Symptoms of poisoning can start six to 24 hours after ingestion, beginning with mild issues that can rapidly become fatal. Health officials warn that cooking, boiling, freezing, or drying toxic mushrooms does not make them safe to eat.

Dr. Christine Wu, Napa County's public health officer, emphasized the dangers of wild mushroom foraging. "Poisonous mushrooms can look and taste similar to safe mushrooms, and even experienced mushroom hunters have been affected by this outbreak," she stated. Officials advise residents to avoid eating wild mushrooms, keep children and pets away from areas where they grow, and only purchase mushrooms from trusted grocery stores.
