https://www.spicely.com/pages/certifications "When we say "Gluten Free" we mean it. Our products are tested, certified and packed in a dedicated gluten free facility. Peace of mind never tasted so good." I have never ordered from this website, but I'm putting together my shopping cart now! To me, it seems like it's not worth the risk to buy spices that are not certified gluten-free. With changes is production and quality control, a non-certified spice could be pretty much gluten-free for a long time and then one may have a reaction to it if something changes in their process. Too much worry for me!
