Abstract
Individuals suering from IgE-mediated food aller-gies are obliged to systematically eliminate the cul-prit allergen from their diet. To support allergic consumers in avoiding food allergens to make in-formed and safe purchasing choices, the European Union (EU) Food Information Regulation (FIR) im-poses a requirement to label the 13 most common allergenic foods (food groups) as ingredients in pre-packed and non-pre-packed foods. e as yet unregulated labelling of unintended presence of allergens has lead to a widespread use of precautionary allergen labelling (PAL) – despite
established allergen management in many compa-nies.  is PAL signi…cantly hampers making a safe food choice, or renders it largely unfeasible, since it is not possible to estimate the actual extent to which allergens are present in a product. Not only food al-lergic consumers, but also the food industry, physi-cians, dieticians/nutritionists, as well as food regu-lators and law enforcement o‰cers would bene…t from a standardized labelling regulation for unin-tended presence of allergens.
