The Food Safety and Inspection Service (FSIS) is amending the poultry products inspection regulations to rescind the regulations that require condemnation of poultry carcasses affected with any of the forms of avian leukosis complex. Avian leukosis lesions will be addressed by the current regulation that provides for any organ or other carcass part affected with tumors to be trimmed and the unaffected parts of the carcass to be inspected and passed. FSIS is also rescinding the regulation that requires young chicken slaughter establishments operating under the New Poultry Inspection System (NPIS) to provide a location along the production line at which an FSIS inspector may inspect the first 300 carcasses of each flock together with associated viscera for leukosis and the regulation that prescribes inspection procedures for avian visceral leukosis in NPIS poultry slaughter establishments.
