California officials warn foragers after person dies from poison mushroom

Several additional people, including children, have severe liver damage amid 21 cases of amatoxin poisoning

California officials are warning foragers after an outbreak of poisoning linked to wild mushrooms that has killed one adult and caused severe liver damage in several patients, including children.

The state poison control system has identified 21 cases of amatoxin poisoning, likely caused by death cap mushrooms, the health department said on Friday. The toxic wild mushrooms are often mistaken for edible ones because of their appearance and taste.
