Fish allergy is an immune hypersensitivity to proteins found in fish. Symptoms can be either rapid or gradual in onset. The latter can take hours to days to appear. The former may include anaphylaxis, a potentially life-threatening condition which requires treatment with epinephrine. Other presentations may include atopic dermatitis or inflammation of the esophagus.[4] Fish is one of the eight common food allergens which are responsible for 90% of allergic reactions to foods: cow's milk, eggs, wheat, shellfish, peanuts, tree nuts, fish, and soy beans.[5]

Unlike early childhood allergic reactions to milk and eggs, which often lessen as the children age,[6] fish allergy tends to first appear in school-age children and persist in adulthood.[7] Strong predictors for adult-persistence are anaphylaxis, high fish-specific serum immunoglobulin E (IgE) and robust response to the skin prick test. It is unclear if the early introduction of fish to the diet of babies aged 4–6 months decreases the risk of later development of fish allergy. Adult onset of fish allergy is common in workers in the fish catching and processing industry.[8][9]
