Fresh corn is always gluten free. Though the term “corn gluten” is used in the animal feed industry to describe the protein, corn does not actually contain gluten. Canned and frozen corn are also gluten free. However, if you are very sensitive, you may want to check into cross-contamination possibilities. Contact the manufacturer to see whether the corn was processed on equipment that protects it from cross-contamination.
