Potential Cross-Reactivity

Review
Salmon are anadromous fish, which means they migrate to the ocean waters as fingerlings to grow but return to the fresh water river beds to spawn. Confusion surrounds the common names of fish in this group. The genus Salmo salar is from the northern Atlantic, the others from the Pacific.
 
Clinical experience
de Martino et al. (1) found 20% of cod-fish allergic children to be sensitive to salmon. Bernhisel-Broadbent et al. (2) found that canned salmon lost definable protein bands when compared to raw and cooked salmon extracts, suggesting that the allergens are more labile than previously thought.
