USDA Amends National List for Organic Livestock and Handling

USDA published a final rule in the Federal Register, amending the National List of Allowed and Prohibited Substances for organic livestock production and handling. This amendment 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. It also reclassifies potassium acid tartrate from a nonagricultural substance to an agricultural substance, requiring handlers to use the organic form when it is commercially available. The amendments take effect May 30, 2019.
