FSA updates best practice guidance on food allergen labelling

PAL should only be used if an unavoidable risk of allergen cross contamination was identified following a risk assessment that cannot be fully controlled through various controls (e.g. cleaning)

PAL statements should emphasize one or more of the 14 regulated allergens that may be unintentionally present in the food.
The term "May contain peanuts" rather than "May contain nuts" should be used on the label to stress the danger that a product may contain a specific ingredient

In addition, the guidance establishes that PAL statement can be used in combination with a ‘vegan’ label, as a ‘vegan’ label highlights different information to a ‘free from’ claim.
