Abstract:
Scombroid poisoning is a common fish-borne disease in clinical settings. Fish that has not been adequately stored after catching can allow bacteria to proliferate, which causes the conversion of histidine to histamine. Once histamine has formed, freezing or cooking the fish will not remove the histamine content. Once the fish is consumed, histamine is released, causing toxicity to the patient with symptoms including cutaneous, gastrointestinal, and anaphylactoid. Emergency nurse practitioners should identify, appropriately diagnose, and treat individuals with scombroid poisoning and avoid misdiagnosing it as fish allergy.
