Step-by-step explanation:
The common allergens or allergenic ingredients that may be present in Walnut Raisin Multigrain products include eggs, mustard, and potentially gluten, milk, soya, celery, sulphites and their derivatives due to processing in a facility that handles these substances. Additionally, walnuts (tree nuts) and raisins can also be potential allergens for some individuals.
