Naturally, oats do not contain gluten, but they can be contaminated by contact with other gluten grains. Nairn's carefully sources pure gluten free oats which are farmed to ensure there is no cross-contamination of the grain throughout the growing and milling process. Made in a dedicated gluten free bakery and tested by Elisa standards (a system approved by GFCP). Also suitable for vegans. 4 packs of 4 grahams.
