[R.O. 1966 § 12:7-56]
A careful post-mortem examination and inspection shall be made of the carcasses and parts thereof of all cattle, sheep, swine and goats slaughtered at official establishments. Such inspection and examination shall be made at the time of slaughter, except in cases of emergencies provided for in Section 13:7-100 of these Revised General Ordinances.
[R.O. 1966 § 12:7-57]
The head, tongue, tail, thymus gland, and all viscera, and all parts and blood to be used in the preparation of meat food products or medical products, shall be held in such manner as to preserve their identity until after post-mortem examination has been completed, in order that they may be identified in case the carcass is condemned, passed for cooking or held for refrigeration.
[R.O. 1966 § 12:7-58]
Each carcass, including all detached parts and organs thereof, in which any lesion or other condition is found that might render the meat or any part or organ unfit for food purposes, and which for that reason would require a subsequent inspection, shall be retained by the inspector at the time of inspection. The identity of every such retained carcass, detached part, and organ thereof, shall be maintained until the final inspection has been completed. Retained carcasses shall not be washed or trimmed unless authorized by the inspector.
[R.O. 1966 § 12:7-59]
Such devices and methods as may be approved by the Health Officer may be used for the temporary identification of retained carcasses, parts or organs. In all cases the identification shall be further established by affixing "retained" tags as soon as practicable and before final inspection. These tags shall not be removed except by an inspector.
[R.O. 1966 § 12:7-60]
Each carcass or part which is found on final inspection to be unsound, unhealthful, unwholesome, or otherwise unfit for human food, shall be conspicuously marked on the surface tissues thereof by an inspector at the time of inspection, "Inspected and condemned." Condemned detached parts and organs of such character that they cannot be so marked shall be placed immediately in trucks or receptacles which shall be kept plainly marked "Inspected and condemned," in letters not less than two inches high. All condemned carcasses, parts and organs shall remain in the custody of an inspector and shall be tanked as required in the regulations in this chapter at or before the close of the day on which they are condemned.
[R.O. 1966 § 12:7-61]
a. 
In all cases where carcasses showing localized lesions are passed for food or for cooking the diseased parts shall be removed before the "retained" tag is taken from the carcass, and such parts shall be condemned.
b. 
Spermatic cords shall be removed from hog carcasses and pizzles from all carcasses.
[R.O. 1966 § 12:7-62]
Carcasses and parts found to be sound, healthful, wholesome and fit for human food shall be passed and marked as elsewhere provided in this chapter.
[R.O. 1966 § 12:7-63]
Carcasses and parts passed for cooking shall be marked conspicuously on the surface tissues thereof by an inspector and at the time of inspection, "Passed for Cooking." All such carcasses and parts shall be treated in accordance with Section 13:7-80 of these Revised General Ordinances, and until so cooked shall remain in the custody of an inspector.
[R.O. 1966 § 12:7-64]
When a carcass is to be dressed with the skin or hide left on, the skin or hide shall be thoroughly washed and cleaned before any incision is made for the purpose of removing any part thereof, or evisceration, except that where calves are slaughtered by the kosher method, the heads shall be removed from the carcasses before washing of the carcasses. The skin shall be removed at the time of post-mortem inspection from any calf carcass infected with the larvae of the "ox-warble" fly (hypoderma lineata and hypoderma bovis).
[R.O. 1966 § 12:7-65]
All hair, scurf and dirt, including all hoofs and claws, shall be removed from hog carcasses, and the carcasses thoroughly washed and cleaned before any incision is made for inspection or evisceration.
[R.O. 1966 § 12:7-66]
The sternum of each carcass shall be split and the abdominal and thoracic viscera removed at the time of slaughter in order to allow proper inspection.
[R.O. 1966 § 12:7-67]
Carcasses or parts of carcasses shall not be inflated with air. Transferring the caul or other fat from a fat to a lean carcass is prohibited.
[R.O. 1966 § 12:7-68]
When only a portion of a carcass is to be condemned on account of slight bruises, either the bruised portion shall be removed immediately and disposed of in accordance with Sections 13:7-108 and 13:7-109 of these Revised General Ordinances, or the carcass shall be promptly placed in a retaining room and kept until chilled and the bruised portion then removed and disposed of as above provided in this section.
[R.O. 1966 § 12:7-69]
a. 
All cattle, calf and sheep lungs, intended for food purposes, shall be inspected to determine whether foreign matter is present in the air passages. The main bronchi and branches shall be slit by employees of the establishment as required by the inspector, and, if ingesta or other objectionable foreign matter has entered these passages, the lungs shall be condemned.
b. 
Cow udders may be saved for food purposes, provided suitable facilities for handling and inspecting them are provided.
c. 
The inspection of udders from cows which have been kept for breeding purposes only shall consist of examination by palpation and, when necessary, by incision. The inspection of udders from cows which have been used for dairy purposes shall include slicing in sections about two inches in thickness.
This slicing shall be done by establishment employees. The udders in the sliced condition shall be given a careful examination by the inspector. The inspector shall designate the udders which are to be sliced. When there is any doubt as to whether the udder is from a cow which has been used for breeding purposes only, then the udder shall be sliced and inspected as provided for udders from cows used for dairy purposes. Each udder shall be properly identified with its respective carcass and kept separated and apart from other udders until its disposal has been determined, when it may be further handled as the conditions warrant.
d. 
The udders from cows officially designated as "Bang's disease reactors" or as "mastitis elimination cows" shall not be utilized for edible purposes.
e. 
Lactating mammary glands of swine intended for edible purposes shall be handled and inspected in the same manner as provided in paragraph c of this section for the udders of cows used for dairy purposes, except that the sliced sections shall be about one inch in thickness. Glands that are passed may be distributed as such but their use in meat food products is limited to the preparation of rendered pork fat.
[R.O. 1966 § 12:7-70]
All cattle infected with cysticercus bovis shall be inspected as follows:
a. 
Head. Prior to inspection the tongue shall be detached sufficiently from the head bones, by an employee of the establishment, to allow a proper inspection to be made of the internal muscles of mastication. These muscles shall be inspected after incising them in such manner as to split the muscles in a plane parallel with the lower jawbone. The masseter muscles shall also be incised, splitting the entire layer between the outer and intermediate fasciae.
b. 
Heart. The preparation and inspection of hearts shall conform to one of the following methods:
1. 
The surface of the heart shall be examined and a longitudinal incision made extending from base to apex through the wall of the left ventricle and the interventricular septum, after which the cut surfaces and the inner surfaces of the ventricles shall be examined.
2. 
After the external surface of the heart has been inspected, the organ shall be prepared for further inspection by an employee of the establishment for severing its attachments and cutting through the interventricular septum and such other tissues as will permit him/her to evert the organ completely. The inspector shall then examine the interior surfaces and make not more than four deep, lengthwise incisions into the muscles of the septum and left ventricular wall, unless the presence of cysts is suspected, when more incisions shall be made (under this method care shall be taken not to cut completely through the walls of hearts to be passed without restriction). If necessary to maintain the identity of hearts, the establishment shall provide consecutively numbered tags and appropriately mark the carcasses and hearts.
3. 
Final inspection of retained carcasses. The external and internal muscles of mastication, the heart and the muscular portion of the diaphragm including its pillars, should be carefully and thoroughly sliced to ensure the finding of all cysts. Prior to the inspection of the diaphragm its peritoneum shall be removed. The tongue shall be carefully inspected by palpation, and if the presence of cysts in the muscles of this organ is suspected, the tongue shall be thoroughly sliced and all parts closely examined for cysts. In addition to the foregoing, the muscles of the esophagus, the exposed muscles, and cut muscular surfaces of the split carcass shall be examined. Incisions may be made to expose additional surfaces if necessary.
