US mushroom poisoning incidents

In late July 2026, a cluster of mushroom‑related poisonings was reported in the United States. First, thirteen children at a YMCA summer camp in East Orange, New Jersey, became ill after eating chocolate edibles suspected of being laced with psilocybin‑containing mushrooms. The children were evaluated by emergency personnel and remained in stable condition; police opened a suspected controlled‑substance investigation but had not filed charges.

A few days later, health officials in Montana reported that ten adults and one minor were hospitalized after foraging and consuming wild mushrooms near Yellowstone National Park. Seven patients remained in serious condition while the specific mushroom species was being identified. Authorities described the incident as isolated and emphasized that there was no broader public‑health threat.

Both events underscore ongoing concerns about accidental ingestion of hallucinogenic or toxic fungi and prompted parallel investigations by state and local authorities, though no criminal proceedings had been announced at the time of reporting.
