The food poisoning of children eating cold fungus may be because fungus contains a substance called porphyrin compounds, which will be released in the human body if they are not fully cooked or treated, causing poisoning reactions.

Specifically, porphyrin compounds will be converted into free radicals and hydrogen peroxide and other reactive oxygen molecules in human body, which will lead to biochemical reactions such as lipid peroxidation, protein oxidation and DNA damage, thus causing a series of symptoms, such as headache, nausea, vomiting, diarrhea, rash, fever and so on.

In order to avoid food poisoning caused by children eating cold fungus, parents are advised to choose formal channels when purchasing fungus to ensure its quality and safety; Soak the auricularia auricula in clear water for more than 30 minutes before cooking, and then blanch it with boiling water until it is cooked; At the same time, be careful not to eat expired or deteriorated fungus. If the child has the above symptoms, he should seek medical advice and inform the doctor that he has eaten auricularia auricula.
