The U.S. Food and Drug Administration announced on May 15, 2025, the launch of a comprehensive postmarket chemical review program designed to systematically evaluate the safety of chemicals currently used in the nation's food supply. This marks a significant shift from the agency's previous reactive approach to a proactive, science-based framework that prioritizes chemicals of consumer concern.
Transition from Reactive to Proactive Oversight
Historically, the FDA conducted postmarket reviews only when triggered by citizen petitions or emerging scientific evidence. The new systematic approach represents what the agency describes as a "proactive, science-based, and built for long-term impact" framework that will provide ongoing surveillance of food chemicals already on the market.
"We are prioritizing our resources and leveraging gold standard science to create, for the first time, a systematic postmarket review program that consumers can trust and rely on," stated FDA Commissioner Martin A. Makary, M.D., M.P.H. "Only by improving the safety and transparency of the food supply and ensuring consumers can make healthful food choices will we overcome the long-standing trajectory of chronic diseases."
Priority Chemicals Under Review
The FDA has identified several categories of chemicals for expedited review under the new program. These include synthetic antioxidant food additives such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT), which are commonly used as preservatives in processed foods. The agency will also prioritize review of azodicarbonamide, a chemical foaming agent used in bread and other baked goods.
Additional chemicals already under scrutiny that will receive expedited attention include phthalates, which can migrate into food from packaging materials, propylparaben, a preservative with antimicrobial properties, and titanium dioxide, a whitening agent used in various food products.
Implementation Timeline and Public Engagement
Over the coming months, the FDA plans to implement several key components of the new program. The agency will release a draft evidence-based approach for prioritizing chemical reviews, which will be made available for public comment to ensure stakeholder input in the process.
The FDA is also finalizing a systematic process for postmarket review that has been developed with extensive stakeholder consultation. This process aims to create standardized methodologies for evaluating chemical safety data and determining appropriate regulatory actions.
Enhanced Transparency Measures
As part of its commitment to increased transparency, the FDA will regularly update its public list of chemicals currently under review. This ongoing communication strategy is designed to keep consumers, industry stakeholders, and public health advocates informed about the agency's review priorities and progress.
The agency has committed to providing regular updates on the program's progress through its official website, ensuring that the public has access to current information about food chemical safety evaluations and regulatory decisions.
Regulatory Context and Public Health Impact
The new program addresses growing public concern about the safety of chemicals in the food supply and represents a significant expansion of the FDA's food safety oversight capabilities. By implementing systematic review processes, the agency aims to identify potential safety concerns before they become widespread public health issues.
This initiative aligns with broader efforts to modernize food safety regulation and reflects the FDA's recognition that proactive oversight is essential for maintaining public confidence in the safety of the U.S. food supply. The program's emphasis on scientific rigor and transparency is intended to provide a foundation for evidence-based regulatory decisions that protect public health while supporting innovation in food technology.
