This is the type of issue where good allergen verification records are needed. Are there other products run in the facility with peanuts and tree nuts, and if so, were good sanitation and other allergen procedures followed. What about supplier control? Do any of the suppliers handle peanut and tree nuts that could have accidentally made their way into a non-nut ingredient.
