Chicken fish syndrome L27.2

Fish is part of the diet of many people, but it is also one of the most allergenic foods. A fish allergy often relates to only one specific species. However, cross-reactions to other fish species are common. The main allergens are parvalbumins.

Allergies to chicken meat are much rarer, especially if they occur independently of the egg allergy.

This is caused by cross-reactivity between parvalbumin, aldolase and enolase in chicken meat and fish.
