Known Hazards
P. porrigens was once generally regarded as edible, though bland. As of 2011, it is a suspect in two outbreaks in Japan involving fatal encephalopathy. Most victims had preexisting kidney disorders. The first incident occurred in September and October 2004 across nine prefectures in Japan, documenting the sickening of 59 people and the eventual death of 17. Most of those who died had preexisting liver problems and the average age of those affected was 70. Death occurred between 13 and 29 days after the onset of symptoms, which occurred at most three weeks after consumption of the species. The second incident occurred in 2009, when a 65-year-old man who had been on hemodialysis died from acute encephalopathy after eating P. porrigens. The mechanism of action for the toxicity of P. porrigens has not been definitively established, but several possibilities have been suggested. It has been demonstrated that P. porrigens contains an unusual amino acid which is toxic to the brain cells of rats in cell culture studies, but it has not yet been possible to definitively determine that this was the cause of the fatal encephalopathies. Other mechanisms have been suggested for P. porrigens's apparent toxicity, including the possibility that the fungus may contain toxic levels of cyanide salts.
