352 VETERINAEY STATE BOARD 



" (a) When there is a tuberculous or other cachexia, as shown by 

 ansemia and emaciation. 



"(b) When the lesions of tuberculosis are generalized. . . . 



"(c) When the lesions of tuberculosis are found in the muscles 

 or intermuscular tissue or bones or joints, or in the body lymphatic 

 glands as a result of draining the muscles, bones, or joints. 



"(d) When the lesions are extensive in one or both body cavities. 



"(e) When the lesions are multiple, acute, and actively pro- 

 gressive. (Evidence of active progress consists in signs of acute 

 inflammation about the lesions, liquefaction necrosis, or the pres- 

 ence of young tubercles.) 



"Rule B : An organ or a part of a carcass shall be condemned — • 



" (a) When it contains lesions of tuberculosis. 



" (b) When the lesion is immediately adjacent to the flesh, as is 

 the case of tuberculosis of the parietal pleura or peritoneum, not only 

 the membrane or part affected but also the adjacent thoracic or 

 abdominal wall is to be condemned. 



"(c) When it has been contaminated by tuberculous material, 

 through contact with the floor, a soiled knife, or otherwise. 



"(d) All heads showing lesions of tuberculosis shall be con- 

 demned. 



"(e) An organ shall be condemned when the corresponding 

 lymphatic gland is tuberculous. 



' ' Rule C : The carcass, if the tuberculous lesions are limited to 

 a single or several parts or organs of the body (except as noted in 

 Rule A), without evidence of recent invasion of tubercle bacilli into 

 the systemic circulation, shall be passed after the parts containing 

 the localized lesions are removed and condemned in accordance with 

 Rule B. 



' ' Rule D : Carcasses which reveal lesions more numerous than 

 those described for carcasses to be passed (Rule C) , but not so severe 

 as the lesions described for carcasses to be condemned (Rule A) , may 

 be rendered into lard or tallow if the distribution of the lesions is 

 such that all parts containing tuberculous lesions can be removed. 

 Such carcasses shall be cooked by steam at a temperature not lower 

 than 220° Fahrenheit for not less than four hours." 



What points determine whether a case of tuberculosis is generalized 

 or local ? 



The term "localized tuberculosis" is applied to cases where 

 there is an infection of a single part of the body with the corre- 

 sponding lymph-glands, or the infection of several parts of the 

 body without the concurrence of the large circulatory system.
