Why did an ordinary sour soup cause food poisoning, and seven people died unfortunately because of eating sour soup? That's because the raw materials for making sour soup have been kept in the refrigerator for a year, resulting in bacteria and mold. Wang and his family didn't know that the raw materials would be moldy, nor did they know that they could not be eaten if they were kept in the refrigerator for too long. It is estimated that Wang never thought that eating sour soup would poison himself and lose his life. Wang will make sour soup with raw materials stored for one year. It is estimated that he will cook authentic sour soup at home to entertain guests on the principle of not wasting, but I didn't expect food poisoning. Later, after inspection by relevant departments, it was confirmed that it was aflatoxin poisoning.
You may not know what Aspergillus flavus is, but I'll introduce it to you here. Aspergillus flavus is a common saprophytic fungus. More common in moldy grains, grain products and other moldy organic matter. The harm of aflatoxin to human health is mainly due to people eating food contaminated by aflatoxin. It is very difficult to prevent this pollution because fungi are very common in food or food raw materials.
Therefore, it is better to use fresh ingredients. Don't be reluctant to throw it away because you think it's a pity to throw it away. A few dollars can compare with life. It would be a pity if you lost your life because you ate moldy food. Although thrift is a virtue, some things should not be stored for too long. You'd better clean the refrigerator regularly, throw away the ingredients that have been stored for too long, and don't make fun of your life.
