A banquet in Heilongjiang was suspected of food poisoning, and 9 people died and 7 people died. Why does sour soup become poison?

Jidong County, Jixi City, Heilongjiang Province? Sour soup? The death toll from poisoning has risen to 8. It was initially identified as a food poisoning incident caused by Pseudomonas cocoanum pollution and rice yeast acid production.

According to the situation at that time, the number of people at the dinner was 12, not 9. Three young people didn't eat sour soup because they didn't like the taste. By noon, nine elders were already unwell. At present, eight people have died of poisoning, of which Li Hongyan is still being rescued.

On the morning of October 5th, 65438/kloc-0, I attended a dinner party in Jixi with my husband Zhang and relatives of 12. What they didn't expect was that this sour soup was actually? Poison? .

In that case, what is sour soup? Why does it cause food poisoning?

First of all, sour soup is a kind of food similar to noodles in Northeast China. After eating in the mouth, there is a sour aroma. So this kind of taste, which many local people like, is also a relatively traditional food.

However, the method of making sour soup requires long-term soaking and fermentation. At this time, if it is infected by Pseudomonas cocoanum subspecies in fermented rice flour, it will cause poisoning.

After all, when making sour soup, first grind the corn into powder, and then soak it in cold water for about 20 days. Then it is crushed into water surface, and the sour taste is filtered out after repeated cleaning. Then you can make dough and put it in the refrigerator. When you want to eat, you can take it out of the refrigerator directly, then press it into strips and cook it in a pot.

In fact, we can find that sour soup needs to be soaked and fermented in the production process. At this time, once infected. Then after eating, there will be symptoms such as vomiting blood, unconsciousness and vomiting. In severe cases, people will directly go into shock and die.

Pseudomonas cocoanum is easy to pollute corn, and Aspergillus oryzae will be produced at this time In fact, this acid bacteria can't be eliminated even if it is boiled at high temperature and high pressure. At this time, the toxicity is particularly great. Eating too much will lead to death, and the mortality rate is as high as 40% to 100%.

It can be seen that this method of making sour soup is difficult to inhibit the acidity of rice yeast, so that people will be life-threatening once they eat it. In this case, we should put an end to making similar food in our lives. After all, our own craftsmanship is not enough to kill these molds. If we eat them by mistake, it will cause harm.

Rice fermented acid has strong heat resistance and destructive power. It can destroy human liver, kidney, heart, brain and other important organs, so it can be seen that rice yeast acid can really cause poisoning.

After sampling and testing, high concentration of Aspergillus oryzae was detected in corn flour and also in gastric juice of patients. At the same time, the poisoning was not caused by aflatoxin, but by Pseudomonas cocoanum pollution, which in turn produced rice yeast acid, which eventually led to tragedy.

What should we do to prevent similar food poisoning?

First of all, don't eat fermented rice noodles, and secondly, foods similar to sour soup should be eliminated. At the same time, those moldy and green foods should also be banned. After all, it is moldy and will do great harm to the body.

If overnight food goes bad and tastes sour, it should also be banned. Only by doing this can food poisoning be prevented. Once poisoned, you should stop eating suspicious food to avoid similar tragedies. There are elderly people at home, and it is generally believed that sour leftovers do not affect eating. In fact, this practice is wrong, and stale food should be thrown away to avoid unnecessary losses caused by small losses.
