The U.S. Food and Drug Administration (FDA) announced that it is reopening the comment period on a 2005 proposed rule to establish a set of general principles to use when considering whether to establish, revise, or eliminate a food standard of identity (SOI). 1/ The 2005 proposed rule adopted the approach of elaborating a set of 13 general principles (listed in Appendix 1 below) that would shape FDA’s consideration of petitions to establish, revise, or eliminate standards. This approach to modernizing SOIs relies on industry and other groups to draft petitions consistent with the general principles for the agency to review in making standards determinations. FDA is seeking new information and public comment on its proposal to create general principles for establishing new food standards and for revising or eliminating existing food standards. Written comments are due by April 21, 2020 and can be submitted to the Federal Register docket number FDA-1995-N-0062.
