<<Disclaimer: Verify this information before applying it to your situation.>> Spoke with Rich Hedlund, Production Manager for Mi Mama's Tortillas brand of corn tortillas. Rich was very informative and assured me the ingredients are gf. When asked about the production process, he told me because of the difference in the way flour and corn tortillas are processed, they can only produce corn torillas in the Tennesee plant where these originate. The company number is 402-345-2099.
