According to the consumption tips issued by the US Food and Drug Administration, fresh tremella is easily infected with pathogenic bacteria and produces toxins due to the influence of cultivation environment and soil. Eating poisonous or deteriorated fresh tremella by mistake may lead to vomiting, abdominal pain, even jaundice, hematuria and convulsions. Because fresh tremella fuciformis is easy to be infected with Pseudomonas cocoanum, the main toxin produced by tremella fuciformis is rice acid.
After being irradiated by sunlight, this toxin will become an isomer of rice yeast acid-Isorice yeast acid, which is not toxic to people. Even if the deteriorated fresh tremella contains mycotoxins, 95.3%~97.6% of the toxins will be destroyed after two days of contact. Therefore, the risk of eating dried tremella is particularly small.
