Store the soaked black fungus in the refrigerator and do not eat it the next day.

Black fungus soaked for too long may produce a pathogenic bacterium called "Pseudomonas cocotoxin", which produces the deadly toxin "rice fermentation acid". The optimum temperature for Pseudomonas cocotoxin production is 26°C, and the optimum temperature for growth is 37°C. The combination of hot weather in summer and a long period of time in a humid environment provides favorable conditions for bacteria to breed and produce toxins.

Rice fermentation acid is resistant to high temperatures. Once it is formed and cannot be burned to death, it will not be destroyed by cooking. After the human body ingests it, it will flow with the blood and reach various organs of the human body. The mortality rate is as high as 50%. Therefore, fungi such as soaked fungus should be eaten as often as possible. If you feel unwell after eating fungus, you should seek medical advice as soon as possible.
