Such results are very significant, and indicate the importance of all
large corporations obtaining the service of systematic and periodic
bacteriological examination of the milk supply. Nor are the results
surprising, for when we remember the habits of the tubercle bacillus
we cannot conceive a more favourable nurture ground than the typical
byre. "Nothing worse than the insanitary conditions of the life of
the average dairy cow," says Sir George Brown, late of the Board of
Agriculture, "can be imagined." It will be obvious that the above facts
make it incumbent upon responsible authorities to see that not a stone
is left unturned to enforce cleanliness in all dairy work, isolation of
diseased cows, and strict treatment of all infected milk.
_Typhoid Fever._ Jaccoud in France and Hart in England have shown that
enteric fever (typhoid) is not infrequently spread by milk. An epidemic
affecting 386 persons in Stamford, Conn., U.S.A., was traced to milk,
97 per cent. of the cases coming from one single milk supply. Dr.
McNail recently recorded an outbreak of twenty-two cases of enteric,
due to a polluted milk supply.
Within the last twelve months much attention has been drawn to a milk
source of typhoid infection by the epidemic of typhoid at Bristol.
Dr. D. S. Davies has pointed out that a brook received the sewage of
thirty-seven houses, the overflow of a cesspool serving twenty-two
more, the washings from fields over which the drainage of several
others was distributed, and the direct sewage from at least one other,
and then flowed directly through a certain farm. The water of this
stream supplied the farm pump, and the water itself, it is scarcely
necessary to add, was highly charged with putrescent organic matter and
micro-organisms. This water was used for washing the milk-cans from
this particular farm, otherwise the dairy arrangements were efficient.
Part of the milk was distributed to fifty-seven houses in Clifton;
in forty-one of them cases of typhoid occurred. Another part of the
milk was sold over the counter; twenty households so obtaining it were
attacked with typhoid fever, and a number of further infections and
complications arose. This evidence would appear to support the fact
that milk may act in the same way, though not in such a high degree, as
water in the conveyance of typhoid fever.
