HOG CHOLERA. 
447 
The question may arise in some minds as to why uncooked 
kitchen refuse and garbage may give rise to the disease. In this 
connection it was quite often found by us that hotel kitchen 
refuse and garbage which was being fed to hogs contained quan¬ 
tities of pork products (especially sausage and pork cuttings). 
It also came to our notice that coincident with the appearance 
of this outbreak, large quantities of pork products from the 
United States had been imported into Winnipeg and that a dis¬ 
tribution of these pork products was made to certain other dis¬ 
tricts, viz., Kenora, Port Arthur and Fort William, and that 
shortly after the distribution of these products there followed, 
almost simultaneously, at each of these districts outbreaks of hog 
cholera, and it would therefore appear quite probable that the 
meats in question had been infected. 
The result of our investigations and inquiries, therefore, fur¬ 
nished very strong circumstantial evidence in support of the be¬ 
lief that many fresh outbreaks of hog cholera are started in subur¬ 
ban districts by feeding uncooked kitchen refuse and garbage 
containing pork or pork products to swine. 
Moore, of Cornell, refers to a serious affection other than 
hog cholera occurring among swine as the result of them being 
fed on kitchen refuse (containing certain alkalies. However, 
while kitchen refuse containing certain alkalies may no doubt be 
the cause of serious affections and losses among pigs, these al¬ 
kalies could not have been the cause of the losses occurring among 
the pigs in the cases referred to, as when hogs were introduced 
on to other premises, coming from any of these upon which this 
hotel swill was being fed, fresh outbreaks were started; showing 
that the disease was essentially of a contagious nature. Again on 
all premises which we kept under observation, where the hogs 
were being fed uncooked swill or kitchen refuse, sooner or later, 
the disease made its appearance and subsequently outbreaks oc¬ 
curred on other premises in close proximity. 
The disease having, in all likelihood, been introduced by this 
means, and involving premises over a considerable area, widely 
separated from each other, centers of infection were set up in 
many districts and serious outbreaks followed thereafter.
