The Food Safety and Inspection Service (FSIS) is proposing to amend the poultry products inspection regulations to rescind the regulation that requires condemnation of poultry carcasses affected with any of the forms of avian leukosis complex. Under the proposal, avian leukosis lesions would 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. The proposed rule would also rescind 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 young chicken slaughter establishments.
