scombroid fish poisoning


Also found in: Dictionary, Thesaurus, Encyclopedia.

scombroid fish poisoning

Poisoning caused by eating raw or inadequately cooked fish of the suborder Scombroidea, such as tuna and mackerel, as well as certain non-scombroid fish, including amberjack, mahimahi, and bluefish. Certain bacteria act on the fish after they are caught to produce a histamine-like toxin. Therefore, these fish should be either properly cooked and eaten shortly after being caught or refrigerated immediately.

Symptoms

Nausea, vomiting, abdominal cramps, diarrhea, flushing, headache, urticaria, a burning sensation and metallic taste in the mouth, dizziness, periorbital edema, and thirst may develop 30 min after eating the fish and last a few hours.

Treatment

Antihistamines reverse many of the symptoms of the syndrome.
