Family: Carangidae
This fish is not a mackerel but a jack, also known as Japanese scad.

Allergen Exposure

This fish is not a mackerel but a jack. It is also called Japanese scad. There are several species of Trachurus, some also called horse mackerel. Other names used are saurel, cigar fish and round robin. The name horse mackerel is also sometimes applied to certain species of tuna and bonito.

Potential Cross-Reactivity

Species within groups of fish, like Gadiformes (examples: codfish and hake) and Scombroid fish (examples: mackerel and tuna) seem to share allergenic components. The overlap of allergen specificity between the groups seems to be moderate or even small.

Clinical Experience

IgE antibodies to Jack mackerel have been measured in asthmatic adults (1), atopic dermatitis patients (2), and food-allergic children (3).
