TUBERCULOSIS IN PIGS—CONTAGION FROM EATING AFFECTED 
MEAT. 
By Pkofessor C. C. Lyford, Minneapolis, Minnesota. 
On the 15th of May I made the trip to the farm in Anoka County, near 
Lally Lake, in company with S. D. Brumhall, Y.S., and Mr. Parker. There 
we found five sows who had twenty-nine sucklings pigs from two to four weeks 
old—which to ordinary observation would be considered in good health. Four 
of these sows were Poland China, the fifth, a Jersey Red. The latter showed a 
tendency to cough—though of so mild a nature that it might not be noticed 
under ordinary circumstances. All of them seemed to eat and feed well, and 
were in good health, excepting one of the Poland Chinas, which had had nine 
pigs two weeks before, and was thought to have run down on that account, 
showing no other signs of disease. 
At first it seemed a question as to how it had originated, but upon investiga¬ 
tion I found that there had been from twenty-two to twenty-five last spring 
pigs all apparently in good health, up to January 1st, prior to which time they 
had run together with fat cattle around farm buildings. During the latter part 
of December six pigs were sent to their farm some four miles away, the others 
still run with cattle as before. About the middle of January a steer about five 
years old became emaciated, the bowels being very loose for some weeks, and a 
cough having appeared. The animal was almost unable to get up, consequently 
was killed and thrown into a back yard for the pigs to eat. Upon examination 
of the steer the foreman of the farm reported that his lungs, liver, spleen and 
kidneys were studded with indications of tuberculi. 
During the month of February three to five barrows became weak, especially 
across the back, and either died or were killed. The foreman reports to have 
opened each of them, and in every case found lungs, liver, and kidneys with 
the same markings as those in the steer. Nothing more was thought of their 
cases until some two weeks ago (May) when eight hogs, apparently in good con¬ 
dition, were received by DeWitt & Sons, Minneapolis, which were killed and 
dressed, and in each and every case the lungs, spleen, and kidneys were more or 
less affected with tuberculi. These were reported having been examined by 
Inspector Davies, DeWitt and|Schwartzkopff. Specimens from the above cases I 
have for investigation. Some weeks prior to receiving the above shipment, six 
hogs were brought from the other farm, being from the litter, as before said, 
which were found in good health, and passed inspection. 
I might here state that we found a seven-year-old cow on the first farm, which 
had been farrow from the past year, being greatly emaciated and having a severe 
cough. This Mr. Parker consented to have killed for investigation. This was 
done and we found her a mass of the tuberculi. Her last calf was killed when a 
few weeks old for veal, and the cow, said to have taken cold at the time of 
calflng, which took place in a severe storm, was dried up and has since been in
