 era will soon return to the nest. 



Principles governing post-mortem inspection 

 have already been discussed. Briefly, extensive 

 changes in the meat or fat should cause condemna- 

 tion. Hog cholera lesions in the kidneys and 

 lymph glands do not condemn the carcass, al- 

 though in cholera-infected herds such lesions prac- 

 tically always establish its status as a virus car- 

 rier. Carcasses that show hog cholera lesions in 

 the kidneys, lymph glands and other organs as well 

 are not used for pork, but if the lesions are slight 

 in extent the fat may be rendered into lard. Most 

 hogs that appear well on foot pass post-mortem 

 inspection as well. 



Garbage Feeding 



Intimately bound up with meat inspection as it 

 applies to hog cholera is the subject of garbage 

 feeding. As we have already shown this prac- 

 tice is the final 'link in the chain which is respon- 

 sible for the introduction of cholera into so many 

 herds of hogs. If meat inspection regulations be- 

 come more stringent, garbage feeding becomes 

 less hazardous; if they become less stringent, or 

 if they are neglected altogether the risks from in- 

 fected pork trimmings in garbage increase. In 

 any event, chance alone decides when any par tic-
