Scombroid Poisoning, ,

Scombroid poisoning is described in the literature as a toxic poisoning caused by ingestion of certain dark meat fish undergoing bacterial decomposition. Poisoning results from the ingestion of a heat-stable toxin. We describe the case of a man who presented to the emergency department several hours after eating tuna steak with evidence of scombroid poisoning that was associated with loss of vision and atrial tachycardia with block. All signs and symptoms resolved after treatment for scombroid poisoning. [McInerney J, Sahgal P, Vogel M, Rahn E, Jonas E: Scombroid poisoning. Ann Emerg Med August 1996;28:235-238.]
