Review this report for a listing of food items offered at Burger King that are made with one or more of the major food allergens. Tables indicate which allergen(s) (e.g., eggs, wheat, soy, peanuts, etc.) the fast food restaurant has declared are included in the recipes for the food.

Flame-Grilled Burgers

Here is the declared list of allergens in Burger King burgers and cheeseburgers. We source this information from Burger King.

If you prefer dairy-free burgers, consider the hamburger, double hamburger, or Whopper.

  • IMPORTANT

Burger King’s Flame-Grilled Burgers are prepared using common toasters that are also used to prepare and cook other foods. In addition to a shared toaster, the Rodeo Burger is made using a shared cooking fryer. As such, the burgers and cheeseburgers may come in contact with additional common allergens.

Many fast food restaurants have limited food preparation areas and do not have the space for separate fryers.

Certain menu items that are not made with a declared allergen may still come into contact with another food item made with egg, milk, wheat, or another allergen.

For example, chicken nuggets are cooked in a shared fryer that may use the same fry oil as mozzarella sticks. As such, chicken nuggets, which are made with wheat may be cooked alongside mozzarella sticks made with soy and milk.

Kids’ Menu

Burger King’s Kid’s burger and cheeseburger are prepared in a shared toaster. The chicken nuggets and fries are cooked in common oil in a shared fryer.

The following allergen chart includes food items on the kids’ menu.

As with many of the other food products at Burger King, breakfast items may be cooked in the same fryer oil and/or toaster as other foods, which can lead to risk of cross contamination.

Here are the declared allergens listed for Burger King’s breakfast menu, including the popular Croissan’wich and Biscuit sandwiches.

Quick Overview of FDA Guidelines

Federal regulations have identified nine major food allergens: eggs, fish, milk, peanuts, sesame, shellfish, soybeans, tree nuts, and wheat.

Highly refined oil, even if derived from one of the major food allergen groups (e.g., soybeans) is exempted from federal regulations. As a result, highly refined soy oil is not considered a common allergen and thus typically not declared on menu items.

It’s important to note that certain foods may be prepared or cooked using shared equipment. Fried foods, for example, are cooked in common oil. As such, foods made without a declared food allergen may come into contact with allergens through cross-contamination.
