Eight cases of allergy-like food poisoning resulting from the ingestion of yellowfin tuna, which had been kept in stock for 10 days prior to being cooked, are described. The main symptoms were headaches, facial flushing and palpitation. Samples of the ingested fish were analyzed for histamine content, and a high level of histamine was confirmed (310 mg/100 g of fish). Corticosteroids were given to 3 patients who exhibited dyspnea or persistent symptoms, while the remaining patients improved without medication. In situations where allergy-like clinical features are present after the ingestion of food, the possibility of allergy-like food poisoning should be recognized and included in a differential diagnosis.
