The swordfish is a large marine predatory fish found in tropical and temperate zones of the Atlantic, Pacific, and Indian Oceans. It is an important food fish rich in omega-3 fatty acids, vitamins B6, B12, niacin, phosphorus, and selenium. Swordfish is often consumed as steaks and has firm flesh similar in texture to marlin.
Swordfish is a potential allergen that can cause immediate allergic reactions, including oral allergy syndrome, urticaria, angioedema, and anaphylaxis. The allergen in this fish is heat-stable, so reactions may occur to both raw and cooked fish. There is a risk of cross-reactivity with other fish species of the Istiophoriformes family, as well as the possibility of allergy from inhaling vapors during fish preparation.
FEIA (Fluorescence Enzyme Immunoassay), ImmunoCAP (Solid-phase Immunofluorescence) – quantitative determination of the allergen.
