Proposed rule · 2026-05598

National Organic Program: National List of Allowed and Prohibited Substances per October 2021, October 2022, and October 2024 Recommendations (Crops and Livestock)

This proposed rule would amend the U.S. Department of Agriculture's (USDA) organic regulations related to organic crop and livestock production. The proposed rule would provide additional tools to organic producers, allowing carbon dioxide in organic crop production and meloxicam as a pain treatment in organic livestock production. Additionally, this rulemaking would remove overly burdensome restrictions for methionine, an amino acid, in organic poultry feed and would affirm that sodium nitrate may be used as a fertilizer in organic crop production, with certain conditions to protect soil quality.
