In 1953, with large-scale reorganization in the USDA, the BAI and Bureau of Dairy were abolished, among other bureaus, and their duties were transferred to the Agricultural Research Service (ARS). The Poultry Products Inspection Act was passed in 1957. This ensured that poultry products shipped in interstate commerce as well as those products being imported into the U.S. were continually inspected for diseases, and that product labels are accurate. In 1958, the Food, Drug and Cosmetic Act of 1938 was amended to include the Food Additive Amendment, addressing concerns over invisible hazards from chemicals added to the foods. Also, the Humane Methods of Slaughter Act was passed in 1958. In 1978, this act was amended to ensure that all meat that was inspected by the FSIS to be used for human consumption was humanely slaughtered.
