The U.S. Department of Agriculture’s National Organic Standards Board (NOSB) has announced an April 29-May 2, 2014, public meeting in San Antonio, Texas, to discuss the work of its six subcommittees and receive input on proposed changes to the National List of Allowed and Prohibited Substances (National List), which governs what may be used in organic handling and production.

Among other things, the meeting will address several petitions proposing  the addition, extension or deletion of substances scheduled for reassessment under the National List’s sunset review rules. In particular, petitioners have requested (i) a National List extension for streptomycin—slated to expire October 14, 2014—to allow “adequate time for the transition from strep over to non-antibiotic, biological alternatives for fire blight control”; (ii) revisions to provisions governing the use of synthetic methionine in poultry feed; (iii) the addition of several synthetic substances used in aquaculture production; and (iv) the removal of synthetic glycerin—which is used in a wide variety of food products—from the National List now that “there is [] sufficient quantity of organically produced glycerin” on the market. NOSB will accept oral comment requests and written public comments on the agenda topics through April 8. See Federal Register and NOSB Press Release, March 10, 2014.
