INSPECTION OF MEAT AND MILIv.

to kill at some central abattoir, or at most in two abattoirs, 
half the difficulty of inspection would be overcome. 
Tuberculosis is not by any means the only disease which 
may be transmitted to the human family through the meat 
supply. Lack of time, however, prevents me from more than 
touching upon some of them. Actinomycosis, a tumor-like af¬ 
fection found upon the jaws of cattle and' sometimes in the 
throat, lungs and tissues, often met with in the muscles of hogs 
on microscopic examination, is seen also occasionally in man. 
The infectious nature of this disease has been proven, as well 
as its identity in men and animals. 
Trichinosis is a parasitic disease more or less common in 
pigs, where the worm, of microscopic dimensions, is found 
curled up in the muscle. If not thoroughly cooked, the pork 
which contains trichinae is liable to affect the person who eats it. 
Tapeworm, a very common disease, can only be produced 
by the ingestion of partially cooked beef and pork,- which 
harbors it in its immature form. Of 1,037 hogs examined in 
Montreal by Dr. Osier and myself, 76 were infested with the 
cysticercus cellulosm, or immature form of the taenia solium, 
one of the most common tapeworms found in man. Circulars 
sent at this time to the physicians of the city revealed the fact 
that at that time no less than 200 persons were suffering from 
this disease. 
Whatever may be the difference of opinion as to the prob¬ 
ability of infection by the meat supply, no such difference of 
opinion exists as to the milk supply. Tubercle bacilli have 
been demonstrated in the milk from tuberculous cows, even 
when there were no lesions in the udder. Such milk is no 
doubt to blame for much of the tuberculosis seen in young 
children. Many diseases in children other than tuberculosis 
are oftentimes referable to milk. To control the milk supply, 
the cows from which it comes must be under some sort of 
supervision. Just how to do it with the best guarantee o^ 
safety, and with the least expense, is a matter to be determined 
upon. Perhaps some such system as the licensing of the dairies 
would solve the matter. Whatever may be determined upon, 
it is certain that this question must sooner or later demand 
the_considerate attention of the public.
