On the evening of 10 12, 2020, there was a food poisoning incident in Jixi, Heilongjiang Province. In this incident, 12 people ate together, and 8 people died. The Heilongjiang Health and Health Commission initially determined that the cause of death was food poisoning caused by high concentration of rice fermentation acid produced by Pseudomonas cocoanum pollution.

What is the first thing to understand? Oryzanol is commonly found in fermented products of cereals, such as deteriorated tremella, auricularia auricula and potato products. The production of such foods usually requires long-term fermentation or soaking. If it is improperly stored or left for too long, it will be easily polluted by Pseudomonas cocoanum in the environment and produce Oryzanol. Rice yeast acid is a kind of toxin, which will cause serious food poisoning and death if ingested into the body. The heat resistance of rice yeast acid is extremely strong, and its toxicity can not be destroyed by boiling water or pressure cooker cooking. It can cause serious damage to important organs of human body after eating. Patients with mild poisoning will generally have symptoms such as nausea, vomiting and mild diarrhea within 2 to 24 hours. If the patient is seriously poisoned, he will vomit blood, be unconscious, twitch or go into shock. At present, there is no specific detoxification drug for rice yeast acid. Once poisoned, the mortality rate is as high as 40% to 100%.

How to avoid such food poisoning?

1. When making cereal fermented food, do not use moldy corn and other raw materials.

Second, when soaking cereals, change water frequently, maintain hygiene, and ensure no odor.

(3) air drying or drying into powder in time after grinding.

Fourth, the storage environment should be ventilated and moisture-proof.

5. When soaking fungus or tremella, clean its surface and eat it in time after soaking.

6. Don't eat fungus that smells or mucus after soaking.

Seven, don't eat fungus overnight after soaking.

Eight, don't eat fresh tremella or fresh fungus.

Nine, consumers in the purchase of human fermented products, should eat on the day of purchase.

X. If suspicious symptoms appear during eating, stop eating suspicious food immediately and try to induce vomiting and seek medical treatment immediately.

Finally, I would like to advise you that the saying "illness comes from the mouth" handed down by our ancestors is very reasonable. Now is the era of advanced science and technology, and we should pay attention to scientific diet in diet.
