The U.S. Department of Agriculture’s (USDA’s) Agricultural Marketing Service has completed the 2016 sunset process for five synthetic and two non-synthetic (natural) substances on the National List of Allowed and Prohibited Substances that governs the use of synthetic and nonsynthetic substances in organic production, processing and handling.

Per the National Organic Standards Board’s recommendations, AMS has renewed approvals for the following synthetic substances used in organic crop production: (i) ferric phosphate for use as slug bait; and (ii) hydrogen chloride for delinting cotton seed for planting. It has also renewed approvals for the following non-agricultural ingredients used in or on organic products: (i) L-malic acid; (ii) any food grade bacteria, fungi, and other microorganism; (iii) activated charcoal from vegetative sources, for use only as a filtering aid; (iv) peracetic acid/peroxyacetic acid when used in wash and/or rinse water according to Food and Drug Administration limitations, for use as a sanitizer on food contact surfaces; and (v) sodium acid pyrophosphate, for use only as a leavening agent. AMS will next reconsider these substance as part of Sunset Review 2021. See Federal Register, February 23, 2016.
