Prolonged soaking of fungus tends to harbor a bacterium called Pseudomonas coccodes, which is more common in living environments but is not fatal.

But it produces a toxin known as mycolic acid, which is a life-threatening behind-the-scenes killer.

Pseudomonas aeruginosa is suitable for growth at 37 degrees Celsius, and the optimal temperature for toxin production is 26 degrees Celsius, so it is common to hear reports of poisoning from edible fungus in the summer months when temperatures are high, mainly due to the harm caused by Mibombic acid to the liver, brain, kidneys and other organs.

After the poisoning of fungus, the patient is mildly manifested as abdominal pain, diarrhea, nausea, vomiting symptoms, and severe hepatic coma, central nervous system paralysis, and even respiratory failure and death.
