Arby's marks the nine US major allergens per item, based on standard recipes that can vary, and says neither it nor its franchisees accept responsibility for individual allergies or sensitivities. Fried items share common oil, so the guide also lists allergens an item may pick up from the fryer (fish only where fish is sold). Highly refined soy oil is exempt from allergen labeling and is not flagged. Some desserts and shakes are made in a facility that handles peanuts or tree nuts. Guests with allergies are asked to tell a team member and to check arbys.com for current information.
