Burger King

This review is based solely on Burger King Ireland’s published allergen information. It reflects what Burger King Ireland reports about the presence or possible cross-contact of the 14 major allergens. Please check Burger King Ireland’s official Nutrition & Allergens menu directly, as ingredients and preparation practices may change. Burger King Ireland provides allergen information at individual menu-item level via its online Nutrition & Allergens menu. Each product listing identifies allergens that are “Contains”, “May contain”, and “May contain via shared equipment.” This approach allows customers to assess allergen risks on a product-by-product basis but does not constitute a standalone allergen policy. Unlike some other major quick-service chains in Ireland, Burger King Ireland does not publish a separate allergen guide or formal allergen policy explaining kitchen practices, allergen handling procedures, staff training, or overall cross-contact controls. There is also no global statement confirming that all food is prepared in shared kitchens or that no items can be guaranteed allergen free. As a result, allergen risk communication relies entirely on the wording provided for each individual menu item. From the available menu information, allergens such as milk, gluten (wheat), eggs, soya, mustard, sesame, and celery appear frequently across burgers, wraps, and chicken products. Fish is repeatedly flagged as a potential allergen via shared equipment, even where it is not an intentional ingredient. Sulphur dioxide/sulphites are also noted as potential shared-equipment contaminants for some items. Burger King Ireland’s menu disclosures confirm that shared equipment is used for at least some products, as indicated by the phrase “may contain via shared equipment.” However, without a broader allergen policy, there is no published clarification on whether this applies universally across kitchens or how allergen risks are managed operationally. Because allergen information is decentralised and item-specific, customers with food allergies must review the allergen statement for every product, every time they order. The absence of a consolidated allergen guide or policy means customers should exercise caution and seek clarification directly from staff where needed. The chain’s allergen information indicates that cross-contact may occur via shared equipment on selected menu items. Menu variability note: allergen information may differ by region or location, so customers should verify details for their specific restaurant. Information reviewed as of: December 2025
