In fact, in this incident, a family and several relatives were at a party, and in the process of dinner, they accidentally ate the expired ones? Sour soup? The total number of people attending the dinner was nine, but in the end, seven people died.

In fact, what happened is like this. In Heilongjiang, there is a kind of food called sour soup. The practice of this food is not particularly complicated. It is to ferment corn flour and directly make this sour soup after fermentation. In fact, many local people in Heilongjiang have eaten this kind of local food. Strictly speaking, there is not much problem with this kind of food itself, but there are some wrong operations in making sour soup, which will lead to the qualitative change of sour soup. Under normal circumstances, if the fermented corn flour is stored in the refrigerator, there is not much problem, but the family took the fermented corn flour out of the refrigerator and put it for a while, and then continued to put it in the refrigerator. Perhaps it is during this period that food will undergo qualitative changes.

Later, according to the field investigation, the chief culprit of food poisoning of these nine people was this sour soup. Now it has been ruled out that it was poisoned by others, which means that the reason why there are toxins in the sour soup is entirely due to operational errors. Because this kind of food will produce a lot of aflatoxin after deterioration, and this element is very toxic, even 56 times that of arsenic.

In fact, this incident is also a wake-up call for many people. It is normal for us to cook some delicious food at home, but we must know how to preserve some foods. Not all foods can be preserved for a long time. For example, some foods can't be stored in the refrigerator, and some foods can't be stored at room temperature, otherwise they will all change qualitatively, which will do great harm to the human body.
