The carcase, if otherwise 



healthy, shall not be con-

it containing tuberculous 



lesions shall be seized.

(a) When the lesions are confined to 

 the lungs and the thoracic lym- 

 phatic glands 



(6) When the lesions are confined to 

 the liver 



(c) When the lesions are confined 



to the pharyngeal lymphatic 

 glands 



(d) When the lesions are confined to 



any combination of the fore- 

 going, but are collectively small 

 in extent 



' In viev? of the greater tendency to generahzation of tuberculosis in 

 the pig, we consider that the presence of tubercular deposit in any 

 degree should involve seizure of the whole carcase and of the organs. 



' In respect of foreign dead meat, seizure should ensue in every case 

 where the pleura has been " stripped." ' 



In connection with tuberculosis of the pig, there is a 

 feeling that the seizure of the whole carcase is unneces- 

 sary ; this question is now under consideration. 



Parasitic Diseases.- — There are certain parasitic conditions 

 of the body which affect its value as meat, or render it 

 completely unfit for food. 



We should unhesitatingly condemn any animal the flesh 

 of which contains any parasite transmissible to man. 

 Such parasites are : 



Cysticercus bovis, producing in man T. saginata. 

 Cysticercus cellulosce, producing in man T. solium. 

 Trichinosis, producing in man the same disease. 



The cysts in C. bovis vary from a millet seed to a small 

 pea, they are spherical or elliptical in shape, grayish in 

 colour, and when enucleated a cavity is left behind in the 

 muscle. The cyst contains the head of the future tape- 

 worm. The parasite only lives about six months in the 

 muscles of the ox; it then dies and becomes calcified. 

 Flesh with calcified cysts may be harmless, but is exces- 

 sively repugnant. 



The muscles most commonly affected are those at the 

 root and frenum of the tongue, the muscles of mastication,
