And if you read further :" No, our corn production lines are dedicated to corn products only. Wheat flour tortillas are produced on dedicated lines."
"All Mission® plants have strict food safety programs in place, including a very comprehensive Allergen Control Program."
Many many of us eat Mission chips and tortillas without ill effect. Just because something is made in the same manufacturing plant or complex does not mean other foods will contain it. The whole world is a " shared facility". Most restauruants and grocery stores are " shared facilities". Many of us live in homes with some gluten eating - " shared facility". Shared equipment would be a greater concern.
Thank you for doing your due diligence and sharing it with "us." I certainly aim to try them in the near future.
