HOG CHOLERA.

f Rutherford, in his report for 1910, refers to the possibility 
of outbreaks of hog cholera being started in suburban districts 
among swine being fed on uncooked garbage, and our experience 
and observations in connection with the recent outbreaks of hog 
cholera dealt with, indicate and support the theory as to fresh 
outbreaks originating from such a source. 
While the outbreaks dealt with by us in the district surround¬ 
ing Winnipeg furnished strong circumstantial evidence in sup¬ 
port of this theory, yet outbreaks at Kenora furnished even more 
striking illustration and convincing proof thereof. 
During October last some disease was reported as causing the 
loss of a number of hogs on the premises of a Mr. H.-- at 
Kenora and upon investigation it was found that the owner of 
these hogs conducted a hotel at Kenora and that the hogs were 
being fed on the swill and kitchen refuse from the hotel. The 
symptoms manifested by these hogs, as well as the post-mortem 
lesions, were characteristic of hog cholera. No fresh hogs had 
been introduced on to the premises in question for a period of one 
year prior to the time of the outbreak. Hogs were also found to 
be affected on the premises of three other owners, which were 
separated from each other by several miles, and upon each of 
which the swine were being fed uncooked swill and kitchen 
refuse obtained from hotels in Kenora. The disease manifested 
itself on all of these premises almost simultaneously without any 
possibility of the infection being introduced either by contact or 
intermediate means from each other’s premises. . 
O11 two other premises in the same district hog cholera was 
subsequently found to be in existence, but the infection in these 
cases was directly traceable to the introduction on to the prem¬ 
ises of hogs which were obtained from one of the parties already 
referred to. 
On further examination of all hogs on premises in the vicinity 
of Kenora, which were kept under observation and inspected at 
intervals covering a period of over three months, it was shown 
t See page 18 in the report of the Veterinary Director General for the year ending 
March 31, 1911.
