FSIS Prohibitions on Air-injection Stunning Devices
Because BSE was confirmed in a cow in the United States on December 25, 2003, FSIS is prohibiting the use of penetrating stunning devices that inject air into the cranial cavity of cattle. This requirement is to ensure that portions of the brain are not dislocated into the tissues of the carcass as a consequence of humanely stunning cattle during the slaughtering process. In emergency rulemaking, FSIS is prohibiting the use of certain parts of cattle carcasses in food.
