<<Disclaimer: Verify this information before applying it to your situation.>> Bob's Red Mill is local and their new gluten-free "clean room" got a lot of press when they first opened it, maybe 2-3 years ago? Anyway, yes, anything of theirs that says "gluten-free" has been processed in the clean room. They have listened to local celiacs and done a lot of research, and feel very secure in that claim. I trust their flours, and if I baked I would use them with a calm mind. Marcy Hoeflein diagnosed 1994 *Support summarization of posts, reply to the SENDER not the CELIAC List*
