HOG CHOLERA AND MEAT INSPECTION 227

 would prevail. 



Ante-mortem inspection could at least be made 

 to incriminate an entire shipment containing hogs 

 obviously infected with cholera to the extent of 

 requiring a more severe interpretation of lesions 

 in individuals contained in it. While it is true 

 that petechiae in the kidneys and peripheral hem- 

 orrhages in the lymph glands, for instance, may 

 be due to causes other than cholera, it is likewise 

 true that in shipments such as we have described 

 these lesions are, with negligible exceptions, con- 

 clusive evidence of the disease. 



License and control of garbage feeding estab- 

 lishments have much to recommend them. Sur- 

 rounding the average city, under present condi- 

 tions, are numerous small herds in which garbage 

 is being fed, and in each one lurks the danger of 

 an outbreak of hog cholera. If a licensing system 

 were in operation, instead of having many un- 

 known sources of infection without any control 

 whatever, we would have a limited number of 

 known sources, in which methods could be so regu- 

 lated as to minimize danger due to spread of the 

 infection. It would be possible to require immu- 

 nization of all hogs fed on garbage an advantage 

 rather than a burden to the individual feeder 

 and it would likewise be possible to govern the
