At that time, after a family of nine ate sour soup, eight people died unfortunately after being sent to the hospital. Now 1 person is being rescued in ICU. At that time, it was absolutely impossible for the family to put the sour soup in the refrigerator for a year and then take it out. No matter what kind of food, you can't eat it if it is frozen for a year. The refrigerator is not a safe for storing food.
The cause of death is that the sour soup contains a substance of rice fermented acid. Excessive consumption of fermented rice acid can cause poisoning, and in the worst case, it will die like this family. However, the substance of rice fermented acid does not reduce its toxin when cooked at high temperature. In order to reduce toxins, it can only be exposed to the sun.
The poisoning incident in this family has also rapidly fermented on the Internet, and many people think that sour soup is a toxin. So now many people refuse to eat sour soup, and many street vendors selling sour soup also said that after this incident broke out, their income was reduced by more than half. In fact, the main reason this time is not because of the sour soup itself, but because they continued to eat it after freezing it for a year. I didn't expect the sour soup to contain toxins.
The next thing I want to tell you is that don't think that the refrigerator is a safe for ingredients. Many toxins and bacteria just grow slowly in the refrigerator, not grow. So we put the food in the refrigerator, and we must finish it in a week. For example, many fermented foods contain some toxins. When we eat, we must have a good check and cook while eating. Don't continue to eat, because we can't eat leftovers.
