Description of content: Notice and request for comments - The Agricultural Marketing Service (AMS) of the Department of Agriculture (USDA) proposes to revise the U.S. Standards for Grades of Mushrooms. The proposed changes would add a grade for portabella mushrooms, remove size from the criteria for each grade and create a separate section for size, and revise the tolerances for defects, consistent with modern production and handling practices. In addition, AMS proposes to update terminology, definitions, and defect scoring guides. Copies of the current U.S. Standards for Grades of Mushrooms are available at https://www.ams.usda.gov/grades-standards/vegetables.
