Since the first of June. 1917, the
Schenectady. N. Y. board of health has
required all milk and cream sold 10
be perfectly p%asteurized excepting
only certified milk.
On July %, 1916. the health com
m%issioners of Chicago issued order
that all milk coming into that city
must be pasteurized. Up to July II
there had been an increase of 1O4 per
cent In the death rate of babies In
that city over the death rate for the
same period in 1915. The commits
sion said, "Pasteurize." No excep-
ions were made. The rule included
all Chicago and all milk coming into
II. II was really the only way to pro-
tect the babies and check the mount
ing death rate. New York safe
guards its babies, so does Cincinnati,
Detroit. Indianapolis, Cleveland. Buf-
falo. Philadelphia. San Francisco and
a few other large cities.
The authorities of Bridgeport,
Conn, figured on a municipal pas
teurizing plant SO that the smaller
dealers might have their milk pas
teurized at a minimum figure when
pasteurization went into effect In
that city In July, 1917.
DR.. Blake, health commissioner OF
Baltimore. was presented with reso-
lutions from a delegation of doctors
recommending the passage of a law

Pasteurization received quite a
strong boost before the eyes OF the
public last summer when Nathan
Strauss, who has done more to intro
duce pasteurization in the United
States than any other individual,
made public a letter which pointed
out that not one of the $500 children
being fed on pa~steurized milk given
out at his eight milk stations had
contracted ~infantile paralysis. This
condition would indicate, he believes.
that impure milk might In some way
carry the disease. Following the
Strauss letter the Diet Kitchen Asso-
citation OF New York city, stated that
only two out of their 2.727 babies
had died OF the malady.
Pasteurized Milk Digestible.
1t has beer claimed by some that
pasteurized milk is less digestible
than raw milk-that the soluble al
bumen becomes insoluble: that part
of the ash, especially the lime salts,
is precipitated. and the casein is al
tered slightly in its physical makeup.
These changes do occur when milk
is heated to pasteurizing temperature
but the fact that they do take place
does not prove that because of these
changes the milk Is less digestible.
Experiments conducted by experts In
this country and in Europe with ba-
bies in the hospitals, also animals, do
not uphold these assumptions. In
fact the bulk of evidence points in
favor of the digestibility of p%asteur-
ICED milk-even the precipitation of
She lime salts by heat does not rem
der the mineral matter OF the milk
less digestible-the lime in the pas
teurized milk being utilized, digested
and assimilated quite as we'll as the
lime in the raw milk. The important
proteids, such as the amino acids
which are essential to the growing
child, and the presence of which i'm
milk places Ii above all other foods
at equal costs, with its ability to
stimulate growth of both bone and
muscle-are not affected by heat,
they remain unchanged. Even If
these changes of the physical and
chemical properties of the milk do oc-
cur, Ii does not necessarily follow
that the milk so changed is less di-
gestible.
But these changes take place only
when pasteurizing at too high a tenn
perature, and do not occur in milk
which is pasteurized to a temperature
OF las degrees and held for 80 min
utes. The pasteurization of milk per-
fectly p~asteurized does not impair 1t
for infant feeding.
Pasteurization Is Effective.
Another evidence of the effective
ness of pasteurization is illustrated
by a recent outbreak of typhoid fever
in Richmond, Cal. The head mixer
on a dairy farm supplying 80 gallons
of milk per day to this city had ty-
phoid fever and infected the milk so
hat IL cases of the disease developed
among the customers served with this
particular milk. The same dairy
supplied 900 gallons of milk per day
to the city of Berkeley, and no cases
of typhoid developed on the routes in
Berkeley. The Richmond supply was
sold raw, while that of Berkeley was
pasteurized.
A milk born outbreak of scarlet
fever in Bergen county, N. j., which
was reported in a recent number of
the Public Health News, was stopped
by pasteurization of the milk.
tuberculosis and septic sore throat

milk. or the diseases transmitted
through the medium of milk, typhoid
fever is the most important. Diph-
iberia and scarlet fever may also be
transmitted through infected milk.
