A fish allergy is an adverse immune reaction to one of the proteins found in fish.
Halibut, tuna, and salmon are the most common fish allergies Due to the high frequency of cross-reactivity, many fish allergic individuals react to several types of fish. Avoidance of all fish is generally advised. Fish allergies are generally lifelong.
Fish allergy and iodine allergy (radiocontrast) are not related. A fish allergic individual is not necessarily allergic to iodine.
