Clinically, there is a kind of "Pseudomonas cocoanum" in overnight auricularia auricula and deteriorated corn flour, which can produce a deadly toxin "mycotic acid", and its poisoning incubation period is mostly half a day to one day, and the longest is three days. At first, patients only have mild symptoms such as nausea, vomiting, diarrhea, dizziness and general weakness, and then they may have symptoms such as jaundice, hepatomegaly, subcutaneous bleeding, hematemesis and unconsciousness. There is no specific medicine for this toxin at present.

Soaked edible fungus ingredients should be eaten with hair, especially in summer. It is best to soak edible fungi in the refrigerator. Not only auricularia auricula, but also tremella, which people often eat, should be paid attention to. If the soaking time is too long, forget to change the water and throw it away decisively. In addition, the fresh fungus on the market should also be carefully selected. If it is sticky, watery or smelly, you must not eat it. If you feel unwell after eating, you should seek medical advice as soon as possible.

Extended data

Edible taboo of auricularia auricula;

1, patients with hemorrhagic stroke should eat carefully.

Although auricularia auricula has the efficacy of sterilization and anti-inflammation, it is comparable to aspirin, but for patients with hemorrhagic stroke, it must be eaten with due diligence. Auricularia auricula can inhibit platelet aggregation, thereby reducing cholesterol content, preventing arteriosclerosis and coronary heart disease, and reducing the risk of cardiovascular and cerebrovascular diseases. However, patients with hemorrhagic stroke have poor coagulation function, so black fungus should be banned.

2. Black fungus can only be eaten after it is cooked.

Some people like cold black fungus. Although refreshing and delicious, it contains a lot of purine nucleoside substances, which have anticoagulant activity, antithrombotic formation and platelet aggregation. But its solubility can only be improved after high temperature cooking, which is beneficial to human digestion and absorption. Therefore, when eating fungus, you must cook it thoroughly, and you must not soak it in warm water and eat it directly.
