<<Disclaimer: Verify this information before applying it to your situation.>> Today I spoke to Doreen in Costco Customer Service. I was happily assured that the cooked chickens they sell from their rotisserie are Gluten free as is the frozen yogurt available in their food court. We love the chicken and use it often so I was pleased to know as a newly diagnosed celiac, I can continue to enjoy it. Wanted to share the information. Renee C. Beverly Hills, Calif.
