<<Disclaimer: Verify this information before applying it to your situation.>> I just got off the phone with Kim Spencer of Nutritional Food Products, P.O. Box 398, Mecca, California 92254, phone 760-396-2116. She confirmed that the corn puffs produced by the company are definitely gluten free, as they only produce one kind of cereal a day and the lines are totally cleaned at the end of the day so there is no cross contamination. The corn puffs are sold under the name Alf's Natural Nutrition, and are available at Wal-Mart Super Centers. They may be available elsewhere, but that is where I purchased ours for 68 cents a bag! They also make puffed brown rice, but I don't recall seeing it as I was only looking for puffed corn. Good news for puffed corn snackers!
