CONGRESS ON TUBERCULOSIS.

cheese manufactories. 
II. ON THE RISKS INVOLVED TO MAN FROM 
TUBERCULOUS ANIMALS (CO-OCCUPATION, 
MEAT, MILK). 
MEANS OF GUARDING AGAINST THEM. 
Conclusions : 
A. —The resemblance of tuberculosis in man and in mam¬ 
mals is no longer denied. Healthy cattle-sheds have been in¬ 
fected by lengthened occupation by consumptive cattle-men. 
The converse is equally possible, at least theoretically. If 
it is not thought possible to prohibit cattle-men from sleeping 
in cattle-houses containing tuberculous cows, the least that can 
be done is to warn the proprietors of the risks of this practice, 
and of the responsibility they may eventually incur. The 
nightly supervision of the suspected cow-shed can be effected 
by means of a glass building looking on to the cattle-sheds, but 
having no direct communication with them. 
B. —Meat obtained from tuberculous animals is rarely dan¬ 
gerous, and when it is dangerous it is only slightly so. The 
established regulations for the inspection of tuberculous meat 
would be sufficient to prevent even the shadow of danger, if 
such regulations were applied always and everywhere. 
Unfortunately this is not the case. 
The inspection of meat is organized only in a small number 
of large towns ; it ought to be done everywhere, in villages as 
well as in towns, and it should be everywhere forbidden to sell 
meat not bearing the stamp showing that it has been declared 
to be wholesome by a competent inspector. This inspection 
could be easily carried out, aud at little cost, on a similar plan 
to that adopted in Belgium for many years. 
C. —The milk giveu by tuberculous cows is rarely danger¬ 
ous, but when it is dangerous it is most often so in a very high 
degree ; hence the necessity of submitting cow-houses to a peri¬ 
odical inspection when the milk yielded is destined for public 
consumption. Cows being really only dangerous when they 
have a tuberculous udder, the inspector’s attention should be 
drawn to the state of the udder. Any cow showing clinical 
signs causing suspicion of the existence of a tuberculous masti¬ 
tis, or of serious visceral tuberculosis ought to be isolated at 
once, pending the making of a diagnosis, this being easily and
