Jack in the Box allergen menu

Jack in the Box reports all nine major allergens for its US menu: milk, egg, fish, crustacean shellfish, tree nuts, peanuts, wheat, soy and sesame. 28 of its 128 items list none of them.

For 2 items (The Cluck Chicken Sandwich and Loaded Breakfast Sandwich), Jack in the Box’s guide does not mark an allergen that the item’s own ingredients or closely related items suggest. Those allergens are marked “Unclear” and the items are left out of the filter results for them.

Jack in the Box kitchens handle soy, egg, fish, milk, wheat and sesame, and shared equipment means an item can pick up one of these even when its ingredients do not list it. Grilled vegetables, eggs and some bakery items are cooked with a butter-flavored vegetable oil that adds soy. The allergen guide does not cover dressings, crunchy toppings, dipping sauces or sauce packets within other items; those are listed on their own. Guests with food allergies are advised to consult their physician and to recheck the information often, since menus and ingredients change.
