USDA Proposes Amendment to Allowed Organic Substances in Livestock

The U.S. Department of Agriculture (USDA) has proposed amending the National List of Allowed and Prohibited Substances to approve elemental sulfur for use in organic livestock production as a topical parasiticide for fleas, ticks and mites. The proposal would also reclassify potassium acid tartrate from a non-agricultural substance to an agricultural substance and require use of the ingredient’s organic form when commercially available. Public comment on the proposed rule must be received by June 29, 2018.
