From Manufacturer's Website:

At last, oats that people with celiac disease or gluten intolerance can enjoy, too! Available in three varieties--Rolled, Quick-Rolled and Steel Cut--and made from oats grown by our cooperative of over 200 farmers dedicated to growing only pure, high-grade oats. Each farm delivery is sampled hundreds of times and tested with an R5 ELISA gluten test to ensure the absence of gluten. Advanced color-sorting removes undetected impurities. Roasting enhances that wholesome robust flavor you expect. Finally, the oats are packaged in our 100% gluten free facility and tested for gluten again to ensure their purity. Although a tiny fraction of the population cannot tolerate even the purest gluten free oats, most will find oats to be a deliciously welcomed addition to their diets. If you're unsure, please consult first with your doctor.
