Feed Innovation at a Regulatory Inflection Point: FDA's 2026 GRAS Reset, the Post-AAFCO Transition and the Emerging Global Dossier Model

The regulatory architecture governing innovative animal-feed ingredients is undergoing one of its most consequential restructurings in decades. In the United States, FDA has proposed converting the historically voluntary GRAS notification system into a mandatory notification framework for many human and animal food substances, while simultaneously reforming its animal Food Additive Petition and GRAS review processes to improve predictability, scientific interaction and data flexibility. These developments follow the end of the long-standing FDA–AAFCO ingredient-review memorandum and the creation of the interim Animal Food Ingredient Consultation pathway. At the same time, the European Union continues to operate a formal pre-market authorisation system under Regulation (EC) No 1831/2003, Great Britain is simplifying its regulated-product authorisation architecture, and ICCF is progressively constructing internationally convergent technical guidance. Together, these changes point toward a new competitive paradigm: successful feed innovation will increasingly depend not merely on ingredient efficacy, but on designing regulatory evidence packages that are modular, internationally transferable and scientifically defensible from the earliest stages of product development.
