U.S. FDA Launches Gluten Labeling Review Focused on Rye, Barley and Oats

Washington, D.C. — Families managing celiac disease and gluten sensitivities may soon see clearer information on packaged-food labels, as federal regulators begin a new effort focused on hidden gluten sources and cross-contact.

On Wednesday, the Food and Drug Administration issued a Request for Information seeking public comments on labeling and on preventing gluten cross-contact in packaged foods. The agency is asking for reports and data related to “ingredients of interest,” including rye and barley (non-wheat gluten-containing grains) and oats that may be contaminated through cross-contact.

FDA Commissioner Marty Makary said people with celiac disease and gluten sensitivities often feel forced to guess about safe options and urged stakeholders to share experiences and evidence to guide future policy.

The FDA said it has received a citizen petition on the issue and reviewed existing reports, but found “serious data gaps,” including limited U.S. information on adverse reactions tied to rye, barley, and potentially contaminated oats. The agency is specifically seeking details such as how often rye or barley may be present without clear disclosure and concerns about oat gluten levels due to cross-contact.

For parents, this is an information-gathering step—not an immediate label change. In the meantime, the FDA notes that “gluten-free” is a voluntary claim with specific conditions, including limits on unavoidable gluten from cross-contact.

Comments are open for 60 days under docket FDA-2023-P-3942 via Regulations.gov. The FDA’s next moves—guidance, enforcement priorities, or new rules—will depend on what it learns during the comment period and review.

What parents should know

• Keep reading ingredient lists carefully, especially for grains and flavored/processed products.
• If your child reacts, document the product and lot details before reporting or submitting a comment.
