(b) Swine which have been injected with hog-cholera virus within 21 days, but not less than 14 days, immediately preceding the date they are offered for slaughter if otherwise in fit condition shall be marked and handled as United States suspects and if slaughtered within the period specified, the carcasses shall be passed for cooking provided the autopsy reveals no cause for condemnation. (c) Swine which have been injected with hog-cholera virus not less than 21 days immediately preceding the date of slaughter shall be given ante-mortem and post-mortem inspection in accordance with the regulations in this subchapter without reference to the injected virus.* [SRA, BAI 289, May 1931] 11.12 Disposition under meat inspection of hyperimmune swine. Hyperimmune swine shall be condemned on ante-mortem inspection if offered for slaughter within ten days after hyperimmunization. Hyperimmune swine offered for slaughter after ten days following hyperimmunization shall be given ante-mortem and postmortem inspection in conformity with the regulations in this subchapter without reference to the injected virus.* [Circ. letter 1711 BAI, July 22, 1931] 11.13 Actinomycosis; disposition of carcasses and parts affected. (a) Carcasses of animals showing generalized actinomycosis (lumpy jaw) shall be condemned. (b) Carcasses of animals in a well-nourished condition showing uncomplicated localized actinomycotic lesions may be passed after the infected organs or parts have been removed and condemned, except as provided in paragraph (c). (c) Heads affected with actinomycosis, including the tongue, shall be condemned, except that when the disease of the jaw is slight, strictly localized, and without suppuration, fistulous tracts, or lymph-gland involvement, the tongue, if free from disease, may be passed, or, when the disease is slight and confined to the lymph glands, the head, including the tongue, may be passed after the affected glands have been removed and condemned.

Carcasses of animals affected with or showing **For statutory and source citations, see note to § 11.1. Page 33 lesions of any of the following-named diseases or conditions shall be condemned: **[Reg. 11, sec. 6] 11.15 Carcinoma or sarcoma; disposition of organs, parts, or carcasses affected. Any individual organ or part of a carcass affected with carcinoma or sarcoma shall be condemned. In case the carcinoma or sarcoma involves any internal organ to a marked extent, or affects the muscles, skeleton, or body lymph glands, even primarily, the carcass shall be condemned. In case of metastasis to any other organ or part of a carcass, or if metastasis has not occurred but there are present secondary changes in the muscles (serious infiltration, flabbiness, or the like), the carcass shall be condemned.*+ [Reg. 11, sec. 7] 11.16 Carcasses showing disease such as generalized melanosis, etc., affecting the system to be condemned. Carcasses of animals showing any disease such as generalized melanosis, pseudoleukemia, and the like, which affects the system of the animal, shall be condemned.** [Reg. 11, sec. 8] 11.17 Abrasions, bruises, tumors; abscesses, pus, etc.; disposition of carcasses and parts. All slight, well-limited abrasions on the tongue and inner surface of the lips and mouth, when without lymph-gland involvement, shall be carefully excised, leaving only sound, normal tissue, which may be passed. Any organ or part of a carcass which is badly bruised or which is affected by a tumor, an abscess, or a suppurating sore, shall be condemned; and when the lesions are of such character or extent as to affect the whole carcass, the whole carcass shall be condemned. Parts of carcasses which are contaminated by pus shall be condemned.*+ [Reg. 11, sec. 9] 11.18 Carcasses so infected that consumption of the meat may cause meat poisoning to be condemned. (a) All carcasses of animals so infected that consumption of the meat or meat food products thereof may give rise to meat poisoning shall be condemned. This includes all carcasses showing signs of either (1) Acute inflammation of the lungs, pleura, pericardium, peritoneum, or meninges. (2) Septicemia or pyemia, whether puerperal, traumatic, or without any evident cause. (3) Gangrenous or severe hemorrhagic enteritis or gastritis. (4) Acute diffuse metritis or mammitis. (5) Polyarthritis. Page 34 Phlebitis of the umbilical veins. **For statutory and source citations, see note to § 11.1.

(b) Immediately after the slaughter of any animal so diseased, the premises and implements used shall be thoroughly disinfected as prescribed elsewhere in the regulations in this subchapter. The part of any carcass coming into contact with the carcass or any part of the carcass of any animal covered by this section, other than those affected with the diseases mentioned in paragraph (a) (1), or with the place where such diseased animal was slaughtered, or with the implements used in the slaughter thereof, before thorough disinfection of such place and implements has been accomplished, or with any other contaminated object, shall be condemned. In case the contaminated part is not removed from the carcass within two hours after such contact the whole carcass shall be condemned.*t [Reg. 11, sec. 10] 11.19 Necrobacillosis, pyemia, septicemia; disposition of carcasses affected. From the standpoint of meat inspection, necrobacillosis (lip-and-leg ulceration) may be regarded as a local affection at the beginning, and carcasses in which the lesions are so localized may be passed for food if in a good state of nutrition, after removing and condemning those portions affected with necrotic lesions. On the other hand, when emaciation, cloudy swelling of the glandular organs, or enlargement and discoloration of the lymph glands are associated with the affection, it is evident that the disease has progressed beyond the condition of localization to a state of toxemia, and the entire carcass should therefore be condemned as both innutritious and noxious. Pyemia or septicemia may intervene as a complication of the local necrosis, and when present the carcass shall be condemned in accordance with § 11.14.*+ [Reg. 11, sec. 11] 11.20 Caseous lymphadenitis; disposition of carcasses and parts affected. (a) A thin carcass showing well-marked lesions in the viscera and the skeletal lymph glands, or such a carcass showing extensive lesions in any part shall be condemned. (b) A thin carcass showing well-marked lesions in the viscera with only slight lesions elsewhere or showing well-marked lesions in the skeletal lymph glands with only slight lesions elsewhere may be passed for sterilization. (c) A thin carcass showing only slight lesions in the skeletal lymph glands and in the viscera may be passed without restriction. (d) A well-nourished carcass showing well-marked lesions in the viscera and with only slight lesions elsewhere or showing well-marked lesions confined to the skeletal lymph glands with only slight lesions elsewhere may be passed without restriction. (e) A well-nourished carcass showing well-marked lesions in the viscera and the skeletal lymph glands may be passed for sterilization; but where the lesions in a well-nourished carcass are both numerous and extensive it shall be condemned. **For statutory and source citations, see note to § 11.1. Page 35 (f) All affected organs and glands of carcasses passed without restriction or passed for sterilization shall be removed and condemned. The term "thin" as used in this section shall not be held applicable to a carcass which is anemic or emaciated.*t [Reg. 11, sec. 12] 11.21 Icterus; disposition of carcasses affected. Carcasses showing any degree of icterus with a parenchymatous degeneration of organs, the result of infection or intoxication, and those which show an intense yellow or greenish-yellow discoloration without evidence of infection or intoxication, shall be condemned. Carcasses affected with icterus, the result of conditions other than those before stated in this section, but which lose such discoloration on chilling, shall be passed for food, while those which do not so lose such discoloration may be passed for sterilization. No carcass affected with icterus may be passed for food or for sterilization unless the final inspection thereof is completed under natural light.*+ [Reg. 11, sec. 13] 11.22 Urinal or sexual odor; disposition of carcasses. Carcasses which give off the odor of urine or a sexual odor shall be condemned. When the final inspection of such carcasses is deferred until they have been chilled, the disposal shall be determined by the heating test.** [Reg. 11, sec. 14] 11.23 Mange or scab; disposition of carcasses affected. Carcasses of animals affected with mange or scab in advance stages, or showing emaciation or extension of the inflammation to the flesh, shall be condemned. When the disease is slight, the carcass may be passed.*t [Reg. 11, sec. 15, par. 1] 11.24 Hogs affected with urticaria, tinea tonsurans, demodex folliculorum or erythema; disposition. Carcasses of hogs affected with urticaria (diamond skin disease), Tinea tonsurans, Demodex folliculorum, or erythema may be passed after detaching the affected skin, if the carcass is otherwise fit for food.*t [Reg. 11, sec. 15, par. 2] 11.25 Tapeworm cysts (cysticercus bovis); carcasses and parts of cattle infested with; disposition of; conditions under which refrigeration or sterilization permitted; calves excepted. (a) Carcasses of cattle (including the viscera) infested with tapeworm cysts known as Cysticercus bovis shall be condemned if the infestation is excessive or if the meat is watery or discolored. Carcasses shall be considered excessively infested if incisions in various parts of the musculature expose on most of the cut surfaces two or more cysts within an area the size of the palm of the hand. (b) A carcass in which infestation with Cysticercus bovis is limited to one dead and degenerated cyst may be passed for food after removal and condemnation of the cyst. (c) Carcasses of cattle showing a slight or moderate infestation other than that indicated in paragraph (b) but not so extensive as indicated in paragraph (a), as determined by a careful examination of the heart, muscles of mastication, diaphragm and its pillars, tongue, and of portions of the carcass rendered visible by the process of Page 36 *+For statutory and source citations, see note to § 11.1. dressing, may be passed for food after removal and condemnation of the cysts, with the surrounding tissues, provided the carcasses and parts, appropriately identified by retained tags, are held in cold storage at a temperature not higher than 15° F. continuously for a period not less than 6 days. As an alternative to retention in cold storage as herein provided, such carcasses and parts may be passed for sterilization. (d) Fats of carcasses passed for food or for sterilization under the provisions of paragraphs (b) and (c) may be passed for food provided they are melted at a temperature of not less than 140° F. The edible viscera, except the lungs and heart, of carcasses passed for food or for sterilization under the provisions of paragraphs (b) and (c) may be passed for food without refrigeration or other process of sterilization provided they are found to be free from infestation upon final inspection. The intestines, weasands, and bladders from beef carcasses, affected with Cysticercus bovis, which have been passed for food or for sterilization may be used for casings after they have been subjected to the usual methods of preparation and may be passed for such purpose upon completion of the final inspection. (e) The inspection for Cysticercus bovis may be omitted in the case of calves under 6 weeks old. The routine inspection of calves over 6 weeks old for Cysticercus bovis may be limited to a careful examination of the surface of the heart and such surfaces of the body musculature as are rendered visible by the process of dressing.

Prior to inspection the tongue shall be sufficiently detached 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 also shall be incised, splitting the entire external layer between the outer and intermediate fasciae. (b) Heart. The preparation and inspection of hearts shall conform to one of the following methods: (1) Method No. 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) Method No. 2. After the external surface of the heart has been inspected the organ shall be prepared for further inspection by an establishment employee severing its attachments and cutting through the interventricular septum and such other tissues as will permit him 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 *For statutory citation, see note to § 11.1. Page 37 |
