Why is mackerel poisonous overnight?
Because mackerel is rich in histidine, when it is stored at high temperature for a long time and the fish body is not fresh (rotten), bacteria containing decarboxylase can deamination with histidine in meat to form histamine. When the histamine content in every 100 grams of fish exceeds 50 mg, poisoning can occur.

In order to prevent histamine poisoning, when eating fresh and salty red meat fish such as mackerel, the internal organs should be removed, washed, cut into pieces, soaked in water for several hours, or braised or steamed, not fried or fried. When cooking, you can put some cabbage and vinegar in moderation, which can reduce the histamine content. When pickling salted fish, mackerel should be fresh and pickled thoroughly, otherwise it may cause poisoning after eating.
