Which set of allergens is listed for the Sakura Wagyu Cheeseburger?

• A. Gluten, dairy, egg, sesame.
• B. Shellfish, dairy, gluten, egg.
• C. Fish, soy, gluten.
• D. Nuts, dairy, egg, gluten.

Answer: (A)

Allergen identification for a menu item looks at which common ingredients bring specific allergens into the dish. For a Sakura Wagyu Cheeseburger, gluten comes from the bun, which is typically wheat-based. Dairy comes from the cheese on the burger. Egg can be present in mayonnaise or other sauces used on the burger. Sesame is often found on the bun as sesame seeds or in sesame-containing toppings. These four—gluten, dairy, egg, and sesame—cover the usual components of this item by default. The other potential allergens listed in the alternative options (like shellfish, fish, nuts, or soy) aren’t standard ingredients in a basic cheeseburger unless a special topping or sauce is added, so they aren’t part of the standard allergen set for this burger.
