Salmon roe (ikura)–induced anaphylaxis in a child

Anaphylaxis is a potentially fatal IgE-mediated allergic reaction of rapid onset. Food ingestion comprises nearly 50% of patients with anaphylaxis presenting to emergency departments in the western world.1 In the United States, 15 million Americans are believed to have food allergies, which correlates to 1 in every 13 children younger than 18 years.1 The most common food allergens are milk, egg, wheat, soy, peanuts, shellfish, tree nuts, and fish. Roes from fish or other aquatic species are not commonly reported as a cause of food allergy in the United States, although it is a much more common allergen in Japan, where fish roe is consumed widely.
