Oats produced under a gluten-free purity protocol: Listing of suppliers and manufacturersTricia Thompson
THIS LISTING IS NOT BEING UPDATED AT THIS TIME. Over the past several months, and based in part on testing data, we realized that we could not assume that the purity protocol suppliers supported by GFWD would inform us of any issues they were experiencing with oats. Along with additional testing of oats, new criteria must be developed for the purity protocol listing (and corresponding responsibilities to GFWD on the part of suppliers/manufacturers included in the listing).
UPDATED OCTOBER 21, 2022: All suppliers of single ingredient purity protocol oats and manufacturers/brands using purity protocol oats in their single ingredient oat products in this listing have updated their information. Please keep in mind that there is no standardized definition for purity protocol oats. Please read the purity protocols for all suppliers.
Inclusion in this listing does not constitute endorsement from Gluten Free Watchdog. Information has been provided by the suppliers and manufacturers. Gluten Free Watchdog has not necessarily tested the products listed here for gluten cross contact.
This listing is provided as a convenience to those consumers who wish to purchase single ingredient oat products from suppliers/manufacturers who source oats grown under a gluten-free purity protocol. Please contact the manufacturers directly to ask about their finished product testing protocols and their handling procedures for purity protocol oats (e.g., steps taken to prevent cross-contact with wheat, barley, and rye once in the hands of the manufacturer).
