The Agricultural Marketing Service includes five commodity programs--Dairy, Fruit and Vegetable, Livestock and Seed, Poultry, and Cotton and Tobacco. The programs provide standardization, grading and market news services for those commodities. They enforce such Federal Laws as the Perishable Agricultural Commodities Act and the Federal Seed Act. AMS commodity programs also oversee marketing agreements and orders, administer research and promotion programs, and purchase commodities for Federal food programs.
