Facial Flushing, Nausea, Sweating, and Palpitations After Eating Fish

Abstract

Scombroid poisoning is the most common fish-borne–related illness that is encountered in clinical practice by clinicians. The presentation of this condition can often mimic that of fish allergies and lead to misdiagnosis and treatment. Nurse practitioners should be familiar with the presentation of scombroid poisoning, risk factors, pathophysiology, and condition management. This case challenge presents a patient presenting to the emergency department with signs and symptoms of scombroid poisoning with the nurse practitioner's diagnostic reasoning while evaluating such a patient.
