SCOMBROID POISONING
A substance like histamine builds up in some fish when they get too warm after they’re caught. Histamine is a chemical that serves as a kind of alarm to let your immune system know that an infection is attacking part of the body. If you eat a fish that was not properly cooled after it was caught, you may react to the histamine that is released into your body.
