<<Disclaimer: Verify this information before applying it to your situation.>> Hi all, I just called House-Autry at 1-800-849-0802 and asked them about their stone ground corn meal. The quality control person told me that they make all their products at the same place including many wheat containing items. She said the ground corn meal falls into the same tub where wheat containing products are mixed. So that answered my question. I thanked her for her honesty. Janet
