<<Disclaimer: Verify this information before applying it to your situation.>> I called to find out the status of their walnuts- there is nothing listed on the label. Ann herself called back and left me a message: they cannot say that any of their products are GF . The nuts come from suppliers -which change frequently and they may use wheat on their conveyor belts or add flour in at some point. Ann's House of Nuts only roasts, and adds flavors and such and then bags them. I was surprised to hear that even their plain nuts were possibly not safe. She did know I was calling due to Celiac Disease- I was impressed!
