{"abstract":"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.","action":"Notice and request for comments.","agencies":[{"raw_name":"DEPARTMENT OF AGRICULTURE","name":"Agriculture Department","id":12,"url":"https://www.federalregister.gov/agencies/agriculture-department","json_url":"https://www.federalregister.gov/api/v1/agencies/12","parent_id":null,"slug":"agriculture-department"},{"raw_name":"Agricultural Marketing Service","name":"Agricultural Marketing Service","id":9,"url":"https://www.federalregister.gov/agencies/agricultural-marketing-service","json_url":"https://www.federalregister.gov/api/v1/agencies/9","parent_id":12,"slug":"agricultural-marketing-service"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2026/04/10/2026-06971.html","cfr_references":[],"citation":"91 FR 18390","comment_url":"http://www.regulations.gov/commenton/AMS-SC-25-0056-0001","comments_close_on":"2026-06-09","correction_of":null,"corrections":[],"dates":"Comments must be submitted on or before June 9, 2026.","disposition_notes":null,"docket_ids":["Doc.
