Shellfish and fish allergies are more common in adults than they are in children. The type of sensitizationSensitization is the first step towards developing a type I allergy. Allergic reactions do not occur upon first contact with an allergen. Before that can happen, your immune system must be able to recognize an allergen. When you get stung by a bee, your immune system will remember the structure of the allergen (= a protein in the insect venom) to be able to produce IgE antibodies against it in the future. This process is called sensitization. usually depends on the fish species available to people in different parts of the world.

Seafood allergy can also lead to anaphylaxisA severe, potentially life-threatening allergic reaction that can lead to a potentially fatal condition known as anaphylactic shock.
