Federal legislation requires humane slaughtering methods and examination for disease for livestock killed for export or interstate trade. The Wholesome Meat Act of 1967 extended inspections to intrastate trade. A new inspection system requiring scientific tests for bacteria was put in place in 1996. The laws are administered by the U.S. Dept. of Agriculture (USDA). The USDA's grading service stamps beef prime, choice, select, standard, commercial, utility, cutter, and canner, according to the amount of its fat. See also beef ; mutton ; sausage .
