The purpose of this legislation, known as the GRAS Oversight and Transparency Act, is to enhance the safety review process for substances used in food that are designated as generally recognized as safe (GRAS). It aims to ensure that these designations are valid and based on current scientific evidence, particularly for substances designated as GRAS before the year 2000. Key provisions of the Act include the establishment of a review board by the Secretary of Health and Human Services, which will evaluate the safety of covered GRAS designations.
