The new Regulation has brought big changes to the way restaurants provide information about allergens in the meals they serve. Caterers have to provide allergen information for all meals they serve. This means if a recipe uses cereals containing gluten such as wheat, rye, barley or oats in the ingredients, they must be able to provide this information to you. Allergen information for non-prepacked food can be provided in written or oral formats. Where the information is not provided upfront and in writing, there must be clear signposting to where the information can be found.
