Food allergy was 1.5% in the total patient group and 12.1% in the allergy label group. The most frequently reported allergenic foods were tomatoes, mushrooms, spices, eggs, milk, and dairy products (Table 3). 12 patients had a history of both food and drug allergy. Of these, 5 patients with fungal allergy were also allergic to penicillin. A patient with a known history of magnetic resonance imaging (MRI) contrast agent allergy developed an anaphylactic reaction to computed tomography (CT) contrast agent and subsequently died. During hospitalization, no adverse allergic reactions were reported in the other patients included in the study.
