31 Pa. Stat. § 483.10
The secretary shall provide post-mortem inspection of all animals or poultry for human food in any establishment in the Commonwealth except as exempted by sections 3 , 5 and 6 of this act. Under no circumstances shall the carcass of animals or poultry which have died otherwise than by slaughter be brought into any room in which meat or poultry products are processed, handled or stored. The head, tongue, tail, viscera and other parts, and blood used in the preparation of meat or poultry products or medicinal products shall be retained in such a manner as to preserve their identity until after the post-mortem examination has been completed. Carcasses and parts thereof found to be sound, healthful and wholesome after inspection and otherwise fit for human food shall be passed and may be marked in the following manner, "Pennsylvania Inspected and Passed," or with the inspection legend of an approved municipal inspection department added thereto. These marks may also include any number given the establishment by the department. Each carcass or part thereof which is found on post-mortem inspection to be unsound, unhealthful, unwholesome or otherwise unfit for human food, shall be marked conspicuously by the inspector at the time of inspection with the words, "Pennsylvania Inspected and Condemned," or with the condemned brand of an approved municipal inspection department added thereto, and such carcasses or parts thereof shall be rendered unfit for human consumption under the supervision of the inspector in a manner approved by the secretary. All unborn or still-born animals shall be condemned and no hide, skin or any other part thereof shall be removed within a room where edible meat or poultry products are handled or prepared. Final dispositions as to wholesomeness of diseased carcasses or parts shall be made by a licensed veterinarian.
