INSPECTION RULES
Governing Reflection si Neat Fron
Tubercular Animals.

DIR. B. F. Kaupp. who Is now Pathol-
ogist of the Veterinary Department OF
the Colorado Agricultural College
spent eight and one-half years as q
veterinary meat inspector for the
United States department Of agricul-
ture. The following is q discussion
by him of the fitness or unfitness Of
meat from cows in different stages ol
tuberculosis.
Two questions often arise: First Il
a COW has tuberculosis. does the milk
contain the tubercle germ? Second.
II COW reacts to the tuberculin test.
is the meat ut for food?
Answer to first question: It has
long been known to comparative
pathologists that IL the udder OF q
COW be tubercular that the milk will
contain the germs. and I have one
case ON record where = whole herd
OF pigs fed on such milk became in
fected with tuberculosis. II the I'D
der IL not tuberculous. will the milk
contain the germs? To determine this
matter positively. experiments were
conducted in the Pathological I.abora-
tory Of the United States Department
of Agriculture. These experiments
covered a period OF three years. The
conclusions Of these extensive experi-
ments are given on page SO Of Bulletin
No. A. U. 8. Department Of Agricul-
ture. which are as follows: THE tu-
bercle bacillus may be demonstrated
in milk from tuberculous cows when
the udders show no evidence Of the
disease"
The bacillus may be excreted from
such an udder in sufficient numbers
to produce infection In experimental
animals both by Injection and inocu-
lation.
From these accurate scientific in
vestigations we must regard the milk
OF a COW reacting to the tuberculin
test as dangerous.
In giving the results Of the accura-
cy OF the tuberculin test we find the
following In the same bulletin. quoted
from the same series OF experiments:
Thus out Of LAG cows injected, but
one reaction was considered ques-
tionable, and. as before stated. the
post mortem ON this animal indicated
that the cause Of this uncertainty was
due either to the minute size OF the
lesion. or the tendency toward en-
capsulation, or both"
In answer to the second question
we are often brought to face the pass
ing or condemnation OF q carcass Of
COW which has reacted to the tu-
berculIn test. AS I have conclusively
shown above that a COW will react to
the tuberculin test no matter what
stage Of development the disease may
be in. the only question left Is to find
the lesion or LESSONS and determine
whether or not 1t Is localized or gen.
eralized. II localized. the diseased
parts must be thoroughly removed
and the carcasses passed. II gener-
allied. II must be condemned and de-
stroyed.
tuberculosis, like actinomycosis
and many contagious diseases of
chronic type. has at first one point OF
infection, and after a long time be-
comes generalized. The localization
or generalization OF this disease can
only be told upon a careful examina-
ton of the organs. glands and other
tissues OF the body after death. Hence
the milk from a COW that has re-
acted to the tuberculin test is always
dangerous, but for food the veterin-
arian has only to determine whether
It Is generalized. or the germs have
entered the blood and started other
centers of disease which 1t will do as
soon as It enters.
The rulings OF the Bureau Of AMI
NAL Industry. u 8. Department Of
Agriculture will not be questioned.
for before these rules were formulated
every comparative pathologist in this
country and abroad was consulted a.
to his opinion az to the conditions un-
der which meat should be condemned.
The vetinary inspector knows the
tubercular lesions az localized. extern
sive, or generalized. and according to
ruling on page five Of B. A. I. Order
No. 125. U. 8. Department OF ASricul-
ture. an inspector has good authori-
ty OF the highest recognition to con-
denim the meat II the condition 10 in
an extensive or generalized one.
and to pass 1t II the lesion be small
and localized. and confined to one
body cavity. or II the lesion 10 thor
oughly calcified and encapsulated.
The meat inspector rules Of this
country. both municipal and federal.
