National Organic Program: Market Development for Mushrooms and Pet Food

Docket Number: AMS-NOP-22-0063
Comments Due: May 10, 2024


The United States Department of Agriculture (USDA) Agricultural Marketing Service (AMS) proposes to amend the USDA organic regulations to clarify standards for organic mushrooms and organic pet food. Specific standards for these products do not currently exist. Instead, these products have been certified organic using the general organic standards for crops, livestock, and handling. However, this approach is not ideal as the current regulations do not address unique aspects of either product. AMS expects this rule would promote development of these markets by increasing regulatory certainty that would, in turn, encourage investment in the markets. The topics addressed by the proposed rule include sourcing of substrate and spawn in organic mushroom production, composting requirements for organic mushroom production, composition and labeling requirements for organic pet food, and the use of certain synthetic substances in organic pet food.
