In a follow-up to an August 2013 final rule on voluntary "gluten-free" labeling, FDA issued a small entity compliance guide with questions and answers to help firms comply with the new requirements. The new federal definition standardizes the meaning of "gluten-free" claims across the food industry. In order to use the term "gluten-free" on its label, a food must meet all of the requirements of the definition, including that the food must contain less than 20 parts per million of gluten. The rule also requires foods with the claims "no gluten," "free of gluten," and "without gluten" to meet the definition for "gluten-free." Beginning August 5, 2014, all FDA-regulated foods must comply with the new rule.
