The U.S. Food and Drug Administration (FDA) has finalized a new, proactive program for the post-market safety assessment of food chemicals, marking a significant step in ensuring ongoing oversight of additives in the nation’s food supply. Alongside this, the agency has initiated formal reassessments of two commonly used chemical additives: butylated hydroxytoluene (BHT) and azodicarbonamide (ADA).
The finalized program introduces a systematic framework for monitoring, prioritizing, and evaluating chemicals present in food based on new scientific information and safety signals. It incorporates streamlined processes and expanded public engagement to enhance transparency. Central to the approach is the use of a “Post-Market Assessment Prioritization Tool” designed to identify food chemicals that pose the greatest potential risks to public health for comprehensive review.
BHT, an additive used to prevent spoilage in fats and oils, is found in products such as breakfast cereals, frozen pizza, baking mixes, and meat products. ADA serves as a whitening agent in cereal flour and a dough conditioner in bread production, with additional applications in food contact materials. The FDA has issued two Requests for Information (RFIs) seeking data on the use and safety of BHT and ADA, inviting food manufacturers, researchers, and consumers to submit relevant information. The public comment period for both chemicals will remain open until July 13, 2026.
FDA Commissioner Marty Makary, M.D., M.P.H., emphasized the agency’s commitment to rigorous oversight, stating the new program provides a “comprehensive, science-based framework” to ensure chemical safety in food. Deputy Commissioner for Food Kyle Diamantas, J.D., described the finalized framework as “systematic” and “transparent,” reinforcing confidence in food safety protections.
The FDA will update the public regularly on the progress of chemical safety evaluations through its “List of Select Chemicals in the Food Supply Under FDA Review.” Full details on the new safety framework and the RFIs for BHT and ADA are available on the FDA’s dedicated post-market chemical safety webpage.
Why it matters
This program represents a shift toward continuous, science-driven monitoring of food chemicals after their market introduction, addressing growing public concern about the safety of additives such as BHT and ADA. By prioritizing chemicals based on potential health risks, the FDA aims to enhance consumer protection and maintain confidence in the nation’s food supply.
Background
Food chemical additives like BHT and ADA have been widely used for decades, but new scientific data or shifting public perceptions prompt periodic reviews. Traditionally, food additives are evaluated before approval; ongoing post-market assessments ensure emerging evidence can trigger safety reevaluations. The FDA’s new framework formalizes and streamlines this process to respond more effectively as food science evolves.
