<<Disclaimer: Verify this information before applying it to your situation.>> Dear List, Thanks for the many replies. I can't say that I have an answer to why I reacted to the Perdue chicken, but I have some possibilities to consider. First, let me give you information I received from Perdue. In my original post I stated "I called Perdue and they assured me that their whole chickens are gluten free. Nothing is added. They are not dipped in anything, and are not even fed gluten containing foods." Since then I have received information in the mail. I may have misunderstood the person I spoke to regarding what the chickens are fed. I don't think she said that they are not fed gluten containing foods, but the foods she mentioned to me were not. However, the booklet I received lists ingredients they are fed and includes wheat and bakery meal. It also states that they are not given hormones and that hormones have not been allowed in US poultry feed since the 1950's. I made a second call to Perdue regarding antibiotics. I was told that they are not given to all chickens, only if a flock has a problem, and then the chickens are not killed until the antibiotics are out of their systems. Penicillin is not used. As for your responses, the possibilities include: crock pot or utensil contamination chickens fed gluten antibiotics food poisoning chicken allergy (6 people) MSG or some other additive some other food allergy had a bug Suggestions: free range chicken Tyson (one person has no problem with Tyson and one person mentioned trouble with Perdue & Tyson) Empire Kosher (no antibiotics or hormones) Bell Evans One person had an extreme DH reaction to Perdue. I found it interesting that 3 non-celiac friends of mine said they have had trouble with chicken causing gas, brick in the stomach feeling, or spastic colon. After not eating chicken again for a couple of weeks, I tried it yesterday. I had the same meal in the same crockpot, but used a different brand of chicken. I had some gas, but nothing compared to the previous reaction. Thanks again for all your input. Linda
