What should be checked to ensure that there are no hidden allergens in a food order?

To ensure that there are no hidden allergens in a food order, it is essential to refer to the restaurant's allergen chart and product case labels. This information provides the most detailed and specific data regarding the presence of allergens in all ingredients used in food preparation. Allergen charts are designed to highlight potential allergens, allowing staff to identify and communicate any risks effectively.

While the guest's verbal instructions, ingredients listed on the menu, and cooking methods are important aspects of food preparation and safety, they may not always provide comprehensive information about all hidden allergens. Guests may not always remember or be aware of all potential allergens they need to avoid, and menus might not list every ingredient or allergen linked to the dish's preparation. Additionally, the cooking methods could cross-contaminate items, but without precise information from allergen charts and labels, it is risky to assume safety based solely on these factors. Therefore, relying on the allergen chart and product case labels is the most effective way to ensure customer safety regarding allergens.
