Poultry Meat allergy: a Review of Allergens and Clinical Phenotypes

Abstract

Purpose of review In the recent years, more cases of poultry meat allergy, both IgE- or non-IgE-mediated, are being reported. Patients have varied clinical reactivity at various levels of sensitivity to different meat preparations. The lack of validated biomarkers renders accurate diagnosis challenging. In this review, we aim to provide an overview of the current status of poultry meat allergy along with a description on the allergens implicated. Recent findings Poultry meat allergy occurs as a result of cross-reactions with known allergens of egg yolk or bird feathers or as genuine IgE-mediated sensitivity to allergens in poultry meat. Individuals can also develop non-IgE-mediated hypersensitivity reactions to poultry meat. Chicken serum albumin is the main responsible allergen in secondary cases, while myosin light chain, α parvalbumin, enolase, aldolase, hemoglobin, and α-actin have been recognized as potential eliciting allergens in genuine poultry meat allergy. Summary There is a wide phenotypic variation among patients with poultry meat allergy, regarding clinical severity and cross-reactivity features. Recognizing the various clinical entities of reactions to poultry meat is an important step towards accurate diagnosis and providing management options that are well received by patients.

“…As an IgE-mediated food allergy, chicken allergy can occur as a secondary allergy in a person who is already allergic to eggs or as a primary allergy to poultry. Allergic reactions that appear to chicken allergy are not only symptoms mediated by IgE, but non-IgE-mediated allergic reactions also appear in chicken allergic patients [29].…”
