I recently noticed a “warning” on the back of Kirkland Quinoa packages sold in my area. It says in part: “Allergen Information: Processed on equipment that also packages products that may contain. . . wheat, . . . .”

I have been buying my quinoa at Costco for years and I believe it used to have gluten free on the label. I don’t know when this warning first appeared. I’m concerned that I might be getting gluten through this source. Any thoughts, experiences? Do you think a thorough rinsing of the quinoa before cooking would help? Thank you in advance for any advice.
