Deliberate inclusion of ingredients which contain allergens is already regulated and packaging should be labelled. Unintentional contamination is not regulated. This paper provides voluntary guidance on the latter.
Evidence from:
Food Standards Agency July 2006.
“Voluntary: Guidance on Allergen Management and Consumer Information.”
Advisory labelling should only be used when, following a thorough risk assessment, there is a demonstrable and significant risk of allergen cross-contamination.
The guidance might form part of a state of the art defence.
