WASHINGTON, D. c., June 27.-
The United States Department Of
Agriculture has issued bulletin
which points to the conclusion that
the real danger from tuberculous cat
tie lies In the manner in which the
germs Of tuberculosis are dissemin-
ated with their feces and that it is
almost entirely through this medium
that milk becomes infected with
tuberculosis. BY series of careful
tests at the Government Experiment
Station in Washington, DIR. E. C.
Schroeder and w. e. Cotton have
demonstrated that cattle discharge
germs of tuberculosis in very large
numbers to the extent very often Of
over thirty-seven million 1r one day
Not only animals which show physi-
cal signs Of tuberculosis, but also those
so slightly infected that the diagnosis
of tuberculosis depends entirely upon
the application OF the tuberculin test,
are said to be in this manner active.
and dangerous sources of infection. -
1t is pointed out that the dairymen
cannot afford to use precautions, the
cost of which is so great that their
applications would convert their bust
ness into philanthropic enterprise,
but that without such care it is prac-
tically impossible to prevent the en-
trance into the milk pail Of the germs
of tuberculosis which have been dis
charged by tuberculous cattle and
which are lodged on the COWS and in
and about the COW stables These
conclusions were reached after series
OF careful tests with a number of cows
which, though they had tuberculosis.
were said to be in better condition
than the majority Of dairy cows in
actual use on dairy farms. The slight
lnfrequent cough with which they:
were affected would not have attract,
ed the attention Of the casual observer
and might have been honestly attri-2
buted by most dairymen to dust in the
air Of the stable. For the most part
tuberculosis would not have been sus-
pected In the case of these animals
had they not been tested with tuber-
cul1n, a test, as 1t is said, not usually
made by the farmer until there Is
grave cause for the suspicion of tuber-
culosis. 3ss& :, ,::s 4 Il Il

ness was observed. This milk. was.
then injected into guinea pigs and it
was >found upon postmortem examin-s
alton that 16 Of the 46 killed had de-
Veloped tuberculosis. It is concluded
from these researches that milk from
tuberlulous cows with unaffected ud-
ders is free from Infection until it has
become contaminated with feces or:
some other material that contains
tubercle bacilli from the outside of the
cows or from their environment. It
Is not believed that tubercle bacilli
are eliminated with the milk from
tuberculous cows unless disease of the
udder or structures connected with It.
is present. This conclusion is drawn
from the present series of investiea-s
tions and is supported by earlier work
relative to the milk Of tuberculous
cows. The present Investigations in
clude only a few cows and a compara-
lively small number Of guinea pigs.
The earlier investigations extend over
dozen years, during which milk from
scores of tuberculous COWS was inject
ed into the abdominal cavities of hun
dreds OF guinea pigs.
The observations made are said to
denn1tely show That the frequency
with which milk contains tubercIe
bacilli is greatly underestinated, espe-
cially when it is milked in the Gus.
tomary way from tuberculcus cows
with healthy udders. or from entirely
healthy COWS in a tuberculous environ
ment.
AS no means are known by which IT
can be determined when cattle become
dangerous to the health Of persons or
animals, every cow affected with
tuberculosis must be regarded in the
opinion OF the government experts as
positively dangerous, In view of the
undoubted presence Of tuberculosis IN
very large number of cattle, whose
owners have no cause to suspect that
this is so. it is urged that every COW
should be periodically tested with
tuberculin. Every COW that reacts and
thus shows that she has tuberculosis
should at once, regardless Of her gem
eral appearance or condition, be re-S
moved from use as dairy COW and
from all contact with dairy cattle or
healthy animals. -. - - sss# s.s
