Section 11.1 Disposal of diseased carcasses and parts; general. The carcasses or parts of carcasses of all animals slaughtered at an official establishment and found at the time of slaughter or at any subsequent inspection to be affected with any of the diseases or conditions named in this part shall be disposed of according to the section pertaining to the disease or condition. Owing to the fact that it is impracticable to formulate rules covering every case and to designate at just what stage a process becomes loathsome or a disease noxious, the decision as to the disposal of all carcasses, parts, or organs not specifically covered by the regulations in this subchapter shall be left to the inspector in charge.** [Reg. 11, sec. 1]

†The source of §§ 11.1 to 11.37, inclusive, (except for amendments and supplemental documents noted in the text,) is BAI order 211 rev., Sept. 1, 1922.

11.2 Anthrax; all parts of carcasses showing, to be condemned; disposition; disinfection. All parts, including hides, hoofs, horns, viscera, intestinal contents, fat, and blood of animals, the carcasses of which show lesions of anthrax, regardless of the extent of the disease, shall be condemned and immediately incinerated or otherwise completely destroyed. The killing bed upon which the animal was slaughtered shall be disinfected with a 1 to 1,000 solution of bichloride of mercury, and all knives, saws, cleavers, and other instruments which have come in contact with the carcass shall be treated as provided in § 8.8 (c) before being used upon another carcass.*† [Reg. 11, sec. 2]

11.3 Tuberculosis; principles for guidance passing on carcasses affected. The following principles are declared for guidance in passing on carcasses affected with tuberculosis:

(a) No meat should be used for food if it contains tubercle bacilli, or if there is a reasonable possibility that it may contain tubercle bacilli, or if it is impregnated with toxic substance of tuberculosis or associated septic infections.

(b) Meat should not be destroyed if the lesions are localized and not numerous, if there is no evidence of distribution of tubercle bacilli through the blood or by other means to the muscles or to parts that may be eaten with the muscles, and if the animal is well nourished and in good condition, since in this case there is no proof, or even reason to suspect, that the flesh is unwholesome.

(c) Evidences of generalized tuberculosis are to be sought in such distribution and number of tuberculous lesions as can be explained only upon the supposition of the entrance of tubercle bacilli in considerable number into the systemic circulation. Significant of such generalization is the presence of numerous uniformly distributed tubercles throughout both lungs, also tubercles in the spleen, kidneys, bones, joints, and sexual glands, and in the lymph glands connected with these organs and parts, or in the splenic, renal, prescapular, popliteal, and inguinal glands, when several of these organs and parts are coincidentally affected.

(d) Localized tuberculosis is tuberculosis limited to a single or several parts or organs of the body without evidence of recent in

vasion of numerous bacilli into the systemic circulation.** [Reg. 11, sec. 3, par. 1]

11.4 Reacting_cattle; examination of popliteal and axillary lymph glands. Instructions concerning post-mortem examination of reacting cattle are modified as follows:

(a) The examination by incision of the popliteal lymph glands and the axillary lymph glands may be omitted in all carcasses of reactor cattle in which no tuberculosis is found elsewhere.

In the examination of all cattle carcasses in which any tuberculous lesion is found, the popliteal lymph glands shall be exposed and incised, if

(1) Á lesion is found in the region of the hind quarters or the skin thereof.

(2) A lesion found in the popliteal lymph gland in addition to the lesions found elsewhere would change the disposition of the carcass. (b) In the examination of all cattle carcasses in which tuberculous lesion is found, the axillary lymph glands shall be exposed and incised, if

(1) A lesion is found in the region of the fore quarters or the skin thereof.

(2) A lesion found in the axillary lymph gland in addition to the lesions found elsewhere would change the disposition of the carcass.* [SRA, BAI 287, Mar. 1931]

11.5 Disposition when affected with tuberculosis. The meat of animals affected with tuberculosis shall be disposed of as follows: (a) Meat of animals. The entire carcass shall be condemned if any of the following conditions occur:

(1) When it was observed before the animal was killed that it was suffering with fever.

(2) When there is a tuberculous or other cachexia, as shown by anemia and emaciation.

(3) When the lesions of tuberculosis are generalized, as shown by their presence not only at the usual seats of primary infection but also in parts of the carcass or in the organs that may be reached by the bacilli of tuberculosis only when they are carried in the systemic circulation. Tuberculous lesions in any two of the following-mentioned organs are to be accepted as evidence of generalization when they occur in addition to local tuberculous lesions in the digestive or respiratory tracts including the lymph glands connected therewith: Spleen, kidney, uterus, udder, ovary, testicle, adrenal gland, and brain or spinal cord or their membranes. Numerous tubercles uniformly distributed throughout both lungs also afford evidence of generalization.

(4) When the lesions of tuberculosis are found in the muscles or intermuscular tissue or bones or joints, or in the body lymph glands as a result of draining the muscles, bones, or joints.

(5) When the lesions are extensive in one or both body cavities. (6) When the lesions are multiple, acute, and actively progressive. (Evidence of active progress consists of signs of acute inflammation about the lesions, or liquefaction necrosis, or the presence of young tubercles.)

(b) Organs and parts. An organ or a part of a carcass shall be condemned under any of the following conditions:

1) When it contains lesions of tuberculosis.

(2) When the lesion is localized but immediately adjacent to the flesh as in the case of tuberculosis of the parietal pleura or peritoneum. In this case not only the membrane or part affected but also the adjacent thoracic or abdominal wall is to be condemned.

(3) When it has been contaminated by tuberculous material through contact with the floor or a soiled knife or otherwise.

(4) Heads showing lesions of tuberculosis shall be condemned, except that when a head is from a carcass passed for food or for sterilization and the lesions are slight, or calcified, or encapsulated, and are confined to lymph glands in which not more than two glands are involved, the head may be passed for sterilization after the diseased tissues have been removed and condemned.

(5) An organ shall be condemned when the corresponding lymph gland is tuberculous.

(c) Carcasses passed for food under certain conditions after removal of parts containing tubercular lesions. Carcasses showing lesions of tuberculosis should be passed for food when the lesions are slight, localized, and calcified or encapsulated, or are limited to a single or several parts or organs of the body (except as noted in paragraph (a)), and there is no evidence of recent invasion of tubercle bacilli into the systemic circulation. Under this paragraph carcasses showing such lesions as the following may be passed, after the parts containing the lesions are removed and condemned in accordance with paragraph (b):

(1) In the cervical lymph glands and two groups of visceral lymph glands in a single body cavity, such as the cervical, bronchial, and mediastinal glands, or the cervical, hepatic, and mesenteric glands.

(2) In the cervical lymph glands and one group of visceral lymph glands and one organ in a single body cavity, such as the cervical and bronchial glands and the lungs, or the cervical and hepatic glands and the liver.

(3) In two groups of visceral lymph glands and one organ in a single body cavity, such as the bronchial and mediastinal glands and the lungs, or the hepatic and mesenteric glands and the liver.

(4) In two groups of visceral lymph glands in the thoracic cavity and one group in the abdominal cavity, or in one group of visceral lymph glands in the thoracic cavity and two groups in the abdominal cavity, such as the bronchial, mediastinal, and hepatic glands, or the bronchial, hepatic, and mesenteric glands.

(5) In the cervical lymph glands and one group of visceral lymph glands in each body cavity, such as the cervical, bronchial, and hepatic glands.

(6) In the cervical lymph glands and one group of visceral lymph glands in each body cavity, together with the liver when the latter contains but few localized foci. In this class of carcasses, which will be chiefly those of hogs, the lesions of the liver are considered

Page 31

to be primary, as the disease is practically always of alimentary origin.

(d) Carcasses for lard, etc., after removal of parts containing tubercular lesions. Carcasses which reveal lesions more severe or more numerous than those described for carcasses to be passed (paragraph (c)), but not so severe nor so numerous as the lesions described for carcasses to be condemned (paragraph (a)), may be rendered into lard or tallow or otherwise sterilized in accordance with Part 15, if the distribution of the lesions is such that all parts containing tuberculous lesions can be removed.*+ [Reg. 11, séc. 3, par. 2]

11.9 Hog cholera or swine plague; disposition of hog carcasses affected. (a) The carcasses of all hogs marked as suspects on antemortem inspection shall be given careful post-mortem inspection; and if it appears that they are affected with either acute hog cholera or swine plague, they shall be disposed of in accordance with paragraph (b). (b) Carcasses of hogs which show acute and characteristic lesions of either hog cholera or swine plague in any organ_or_tissue other than the kidneys or lymph glands shall be condemned. Inasmuch as lesions resembling lesions of hog cholera or swine plague occur in the kidneys and lymph glands of hogs not affected with either hog cholera or swine plague, carcasses of hogs in the kidneys or lymph glands of which appear any lesions resembling lesions of either hog cholera or swine plague shall be carefully further inspected for corroborative lesions. On such further inspection

(1) If the carcass shows such lesions in the kidneys or in the lymph glands or in both, accompanied by characteristic lesions in some organ or tissue, then all lesions shall be regarded as those of hog cholera or swine plague, and the carcass shall be condemned.

(2) If the carcass shows in any organ or tissue other than the kidneys or lymph glands lesions of either hog cholera or swine plague which are slight and limited in extent, it shall be passed for sterilization in accordance with Part 15.

(3) If the carcass shows no indication of either hog cholera or swine plague in any organ or tissue other than the kidneys or lymph glands, it shall be passed for food unless some other provision of this subchapter requires a different disposal.*+ [Reg. 11, sec. 4]

11.10 Hog cholera, additional instructions concerning disposition of carcasses on account of. In disposing of certain carcasses on account of hog cholera, the following additional instructions shall be observed:

(a) Inconclusive but suspicious symptoms of hog cholera observed during the ante-mortem inspection shall be duly considered in connection with post-mortem findings and when the carcass of such a "suspect" shows lesions in the kidneys and the lymph glands which resemble lesions of hog cholera, they shall be regarded as those of hog cholera and the carcass shall be passed for cooking.

(b) When a hog which on ante-mortem inspection showed no symptoms of hog cholera, but on post-mortem shows lesions in the kidneys and lymph glands which resemble lesions of hog cholera and in addi
