The 5 Major Allergens at Taco Bell

Soy
Soy appears in several key items. The most important sources are seasoned beef, the Chalupa Flatbread, and the Fire Sauce packet.
Confirmed soy sources:
- Seasoned Beef: Contains Soy (from soy lecithin). This beef does NOT contain wheat.

Sesame
Sesame became a major allergen under the FASTER Act, effective January 2023. Based on a full review of Taco Bell’s current official ingredient list, no menu items declare sesame as a “Contains” allergen. Therefore, sesame does not appear in the allergen tables below. However, formulations change without notice. Always verify at Taco Bell app before ordering if you have a sesame allergy.
