USDA Amends National List For Organic Livestock And Handling

(WASHINGTON, D.C.) – The U.S. Department of Agriculture today published a final rule in the Federal Register to amend the National List of Allowed and Prohibited Substances based on public input and the November 2017 National Organic Standards Board recommendations for livestock and handling.


This final rule:
Allows elemental sulfur to be used in organic livestock production as a topical treatment to repel mites, fleas, and ticks from livestock and their living spaces.
Reclassifies potassium acid tartrate from a nonagricultural substance to an agricultural substance, requiring handlers to use the organic form when it is commercially available. Potassium acid tartrate is currently listed as a nonorganic ingredient allowed in organic products.
This final rule is effective on May 30, 2019.
