<<Disclaimer: Verify this information before applying it to your situation.>> I called Mid-America Farms (now Dairy Farmers of America) and they assured me that their cheese, including processed American Cheese is GF. They use a powdered cellulose in packaging and that's all. If they ever use a flour, it's rice flour. Sam's club sells the American (and Swiss too, I believe) in bulk. I'll try it today. Has anyone else used this cheese successfully? I'm always nervous to try new things because its for my little ones. Thanks, donna
