A bill working through Congress could require food manufacturers to disclose gluten cross-contact on packaging for the first time. The Celiac Safety Act of 2026, analyzed recently by Packaging Digest, would close a gap that has frustrated celiac families for years: a product made on shared equipment with wheat can be sold today with no warning at all — and that is entirely legal.
The current FDA gluten-free labeling rule applies only to products that voluntarily claim to be gluten-free. Everything else operates in a regulatory gray zone. Naturally gluten-free foods — rice cakes, corn chips, many snack products — may be produced on the same equipment as wheat-based foods with no obligation to tell celiac shoppers. When we covered the bill’s introduction in Celiac Safety Act of 2026 Introduced in House of Representatives, the focus was on the legislation itself. The Packaging Digest analysis shifts to the industry side: what would compliance actually require of food manufacturers, and what would change on the labels celiac families rely on?
What This Means for You
The most important change the Celiac Safety Act would bring: cross-contact disclosure would be required, not optional.
Right now, whether a manufacturer discloses cross-contact risk is entirely voluntary. Some companies do it. Many don’t. And when they do, the language varies — “may contain wheat,” “manufactured in a facility that also processes wheat,” “produced on shared equipment with wheat, milk, soy, and peanuts.” None of those phrases carries a standardized meaning. None is required by law. Celiac families are left interpreting ambiguous warnings with no consistent legal definition behind them.
Under the Celiac Safety Act, manufacturers would need to use uniform language when cross-contact with gluten-containing grains poses a realistic risk. That means an advisory label on one brand’s rice crackers would carry the same legal weight as the same warning on a different brand’s corn chips. For anyone navigating a grocery store with a real medical need and limited time, that consistency is not a minor convenience — it’s a meaningful safety upgrade.
For celiac parents like me, the current system demands constant detective work. Determining whether a product is genuinely safe for my son often means hunting for allergen statements buried in fine print, calling manufacturer hotlines, and ultimately making a judgment call with incomplete information. Standardized mandatory disclosure would not eliminate all uncertainty, but it would give families a reliable legal baseline to work from.
Key Takeaways
- Cross-contact disclosure would become mandatory for products processed on shared equipment with wheat, barley, or rye
- Current FDA rules only cover products labeled “gluten-free” — foods without that claim face no gluten disclosure requirements today
- Advisory warning language would be standardized, replacing today’s patchwork of inconsistent voluntary phrases
- Manufacturers would need to audit production lines and update packaging to reflect required disclosures
- The bill targets a structural gap in the existing 20 ppm standard that leaves many naturally gluten-free products unregulated
The Science
Want to understand the regulatory framework driving these labeling changes? Here’s a walk through the technical details, with every term defined. No legal degree required.
The 20 ppm Standard and Its Limits
The FDA’s current rule, finalized in 2013, sets a 20 ppm (parts per million) threshold — meaning a food bearing a “gluten-free” claim must contain fewer than 20 milligrams of gluten per kilogram of food. Clinical evidence at the time of rulemaking indicated most celiac patients tolerate gluten at that level without detectable intestinal damage.
But the rule has a structural gap. It governs the claim, not the food. A product that never uses the words “gluten-free” sits entirely outside the rule’s scope, even if it’s a naturally gluten-free food made in a wheat-processing facility. That regulatory blind spot is what the Celiac Safety Act targets.
Some researchers and advocacy organizations argue the 20 ppm threshold itself may be too permissive for a subset of celiac patients — and that cumulative daily exposure across multiple “safe” products adds up to a harmful dose over time. The Celiac Safety Act may address that threshold as well, though revising the number is a separate and more contested fight. As we explored in Advocating for Clearer Labeling of Gluten in the U.S., the push for reform has been building for years on multiple fronts.
What Mandatory Cross-Contact Disclosure Would Require
Cross-contact — the unintentional transfer of gluten proteins from one food to another through shared equipment, surfaces, or production environments — is how naturally gluten-free products become unsafe for celiac patients. It is distinct from a food that contains gluten as an ingredient.
The proposed legislation would require manufacturers to evaluate their allergen control plans (the documented procedures companies use to prevent unintended allergen transfer) and determine whether cross-contact with wheat, barley, or rye creates a realistic risk. When it does, disclosure would be mandatory.
This is a significant shift in how the industry operates. Today, many manufacturers add or omit advisory statements based on their own legal counsel and risk tolerance, not a standardized framework. A mandatory system would require companies to make explicit, documented determinations — and stand behind those determinations on the label.
Barley and rye deserve specific attention here. Neither grain falls under the Food Allergen Labeling and Consumer Protection Act (FALCPA), the federal law that mandates disclosure of the eight major allergens — which includes wheat but not the other two gluten-containing grains. This means barley and rye currently receive even less mandatory attention than wheat in allergen labeling. The Celiac Safety Act would need to explicitly address all three grains to be effective for celiac patients.
What Packaging Changes Would Look Like
From a manufacturing standpoint, the Packaging Digest analysis identifies a real compliance burden: food companies would need to audit production lines, update allergen assessments, and redesign packaging on a timeline set by Congress and enforced by the FDA.
For smaller manufacturers with less formal allergen control infrastructure, that process is genuinely demanding. For large manufacturers already running comprehensive allergen audits, the changes may be largely administrative — updated documentation and revised label copy rather than new production protocols.
The enforcement mechanism matters enormously. A labeling requirement with no penalty structure is a suggestion. If the Celiac Safety Act includes real consequences for non-compliance — recall authority, civil penalties, mandatory FDA audits — the label disclosure it requires becomes meaningful. Without teeth, it risks joining the long list of well-intentioned food safety reforms that changed the packaging but not the risk.
For celiac families, the outcome that matters is simple: a warning on the label that means something, backed by law, consistently applied. That is what voluntary disclosure has never delivered, and what the Celiac Safety Act could.
