The U.S. Food and Drug Administration has taken several significant steps this month to expand and formalize its post-market review of food chemicals already in commerce. On May 12, 2026, FDA finalized a systematic post-market review process shaped by stakeholder input, released for comment a draft prioritization scheme for reviewing existing chemicals, and updated its list of chemicals under review, including butylated hydroxytoluene (BHT) and azodicarbonamide (ADA).
