Cross Contamination
According to the Mayo Clinic, when a variety of gluten-free products come into contact with products such as grains containing gluten, cross-contamination may occur. This is common in factories that process both regular and gluten-free products and use the same machines for both. The other place cross-contamination can occur is in the kitchen. It occurs most commonly when preparing meals and sharing the same kitchen tools and surfaces. Use extreme care and have a back up cutting board that is only used for preparing gluten-free items to avoid cross-contamination
