News Details

On May 12, 2026, the U.S. Food and Drug Administration (FDA) finalized a new post-market assessment program for food chemicals and launched reassessments of butylated hydroxytoluene (BHT) and azodicarbonamide (ADA).  

New Food Chemical Assessment Program 

The new post-market assessment program introduces a structured, science-driven approach to continuously evaluate chemicals already present in the food supply. The framework focuses on identifying potential safety signals, prioritizing chemicals for review, and ensuring transparency when communicating findings to the public. 

The FDA has also introduced a prioritization tool to identify chemicals that may pose higher health risks and require a detailed assessment. Enhancements include simplified evaluation criteria and a greater emphasis on public health outcomes. Additionally, the framework incorporates improved opportunities for public participation and feedback, ensuring broader stakeholder involvement. 

Reassessment of BHT and ADA 

The FDA has initiated the reassessments of two widely used food additives: butylated hydroxytoluene (BHT; CAS No. 128-37-0) and azodicarbonamide (ADA; CAS No. 123-77-3). BHT is commonly used to prevent spoilage in products such as cereals, baked goods, and frozen foods, while ADA serves as a flour whitening agent and dough conditioner. The agency has issued Requests for Information (RFIs) to gather updated scientific data on their safety and usage. 

Next Steps and Timelines 

Public comments on the reassessment of BHT and ADA are open until July 13, 2026. The FDA will continue to provide updates through its ongoing review list, thereby reinforcing its commitment to maintaining safety standards as new scientific evidence emerges. 
Full details of the requested data are available in the RFIs for BHT and ADA, and both framework documents are published on the FDA's new post-market safety of chemicals in food webpage.
