• Animal feeding operation (AFO): An AFO is a facility that raises animals in a confined area void of grass or vegetation for 45 days or more per year.
• Concentrated animal feeding operation (CAFO): A CAFO is an AFO that has 1,000 animals or more. CAFOs make up 15% of AFOs.
• Animal welfare: The Humane Methods of Slaughter Act, passed in 1958, is enforced by the U.S. Department of Agriculture's (USDA) Food Safety and Inspection Service and ensures the humane slaughter and handling of livestock.
