Most fast food restaurants have stopped frying their food in peanut oil for the safety of customers with peanut allergies. Only a few chains still use peanut oil — namely Chick-fil-A, Five Guys, and Jimmy John’s. However, several chains, including McDonald’s and Burger King, still use some peanut or tree nut products, most commonly in desserts.
The FDA exempts labeling highly-refined peanut oil as an allergen since some peanut-allergic individuals can safely consume it, so it can be hard to spot the restaurants that do still use peanut oil.
Below, we have the details of which fast food restaurants use peanut oil, which ones use other peanut products, and which ones don’t use peanut products at all.
If you have a peanut allergy and are considering visiting a fast food restaurant near you, keep the following information in mind:
- While there are restaurants that don’t use any peanut products, some still sell products manufactured in facilities that process peanuts or tree nuts.
- Even though most restaurants require peanut products and other allergens to be separate from other food products, if your allergy is severe, you may want to speak with the staff about the potential for cross-contamination before ordering your food.
- Many fast food chains are franchises. While they’re required to follow the rules set out by corporate, there’s a chance that some may not adhere to every regulation — meaning that even if a corporation requires its stores to refrain from using peanut oil or peanut products, some franchises may disobey that rule.
It’s always a good idea to check the restaurant’s website for allergen information, call the restaurant, and/or make sure the staff is aware of your allergy before you order to avoid cross-contamination or accidental exposure to allergens.
