Here's what they say about their gluten-free oat flour:
"Our Gluten Free Oat Flour is milled from the purest gluten-free oats grown by over 200 farmers on clean, dedicated oat-growing fields. This whole grain flour is excellent for adding to gluten free baked goods to impart a true oat flavor and wholesome nutrition. The flour is milled and packaged in our 100% gluten free facility and tested for gluten to ensure purity."
Note: The reason there is a problem with regular oat flour purchased in a grocery store is that it is milled in the same place as other wheat flours and cross-contamination can and does occur. The other reason is that farmers could be growing wheat and oats near each other and during harvest time cross-contamination can also occur. Oat flour itself does not contain gluten which is great news as oat flour is a lovely flour, lower in carbs than white flour and much tastier - plus it produces baking with a soft, moist crumb. People with a gluten intolerance may think they are reacting to oat flour if it produces gas, but sometimes oats can do that to a person, especially oats themselves vs oat flour.
