FIRST MILESTONE
PASSED BY POLK
COUNTY DAIRY CO.
Prosperous Growth Shown By
This Firm-First To Pasteur-
ize Milk In Lakeland

ed their products, Pasteurized Milk.
Purity Maid" ice cream and other
dairy products to the public.
The company is an organization OF
local people many of whom were in
the dairy business and felt that it
would be better to handle their milk
through central plant. giving the
people a more sanitary food and bet
ter service as well as creating an
outlet for their surplus milk in the
form of ice cream.
This was the first pasteurized milk
ever offered for sale in Lakeland and
it met with some opposition due to
the fact that some people did not I'M
derstand what was meant by pasteur
izatiOn.
What pasteurization means and the
origin of the term Copied from the
Circular No. 1S4 of the Department
of Agriculture, Bureau Of Animal In
dustry. Washington. D. c.
"Pasteurization as applied to milk
is the process of heating for Il long
or short period as the different meth.
DDS demand at temperatures usually
between $40 and 1S5 +. The process
must be followed by rapid cooling.
the term originated from the expert
ments of Pasteur, in France, from
1860 to 1864. on the diseases of wine.
in which he found that heating for
a few moments at a temperature OF
122 to $40 F.. was sufficient to pre-.
vent abnormal lamentations and
souring of the wine. A little later
Pasteur found that by a similar heat
ing beer gould be preserved from
souring. The application of the
process gave rise to the term pas
teurization."
Value of Pasteurization
The value of pasteurization from 4
sanitary standpoint is of the greatest
Importance when market milk is under
consideration.
In the first place, the pasteuriza-
ton of milk. when the process is pro-
perly performed affords protection
from pathogenic organisms. Such
disease-producin bacteria as Bacillus
tuberculosis. b. Typhi, 3. Diph-
therioe, and the dysentery bacillus
are destroyed, or at least have lost
their ability TO produce diseases. when
heated at lao f. for twenty minutes
or more. Although the infective
agent in scarlet fever is unknown,
epdemics of the disease have been
traced to milk supplies. and in such
cases pasteurization has been report
ed as a means of safeguarding the
public. with apparently satisfactory
results.
In the second place, pasteurization
causes a reduction of the infantile
death rate due to the ordinary intes-
final disturbances. Numerous expert
ments definitely prove the value of
pasteurization in this connection.
While it has not been possible TO
isolate any special organisms which
act as the causatiye agents in the
common infantile' intestinal troubles
other than the one producing dysen-
terry. il seems that high bacterial
numbers in the milk are associated
with such diseases. Commercial pas.
teuriZation as practiced at the pres
ent time with reasonable care de-
stroys about ninety-niue per cent of
the bacteria, but it does not prevent
the ultimate securing of milk, although
it does delay the process.
In this plant modern equipment
and methods are used. The milk is
first strained through many thick
nesses of absorbent cotton after which
it is handled entirely by machinery.
carried through sanitary tubes by reg
ular sanitary milk pumps and bottled
and capped automatically; even the
little cap on the bottle is made and

never touched by human hand.
Milk is received at this plant twice
cacn day and what is not sold as
fresh milk enc day is not used the
next hut goes to the ice cream depart
men.
Special care is taken as to the clean
illness of the plant and each time that
milk is handled the entire system,
is thoroughly washed with hot water
and Wyandotte washing powder then
rinsed and steriliZed with steam.
The management is always glad to
have visitors and will take pains to
explain the different machines and
processes and really prefers that they
come when the plant is in operation.
During the tourist season a number
ness from the north, east and west
were entertained here and some very
high compliments were received as
to the cleanliness and gncral appear
ances Of the plant and its equipment.
As to the Purity Maid' ice cream
it was a success almost Immediately
from the start and today in Lakeland
it is STANDARD equipment" at social
affairs as well as being handled by
all leading drug stores.
Or course the daily sales were
small at first but long before the
first year had rolled around they had
grown to a very substantial figure and
it is now being shipped as far north
AS Ocala and as far south as Fort
Myers and Bradentown as well as to
intermediate points.
Purity Maid" ice cream is very
rich in butter fat and other milk sol
ids. . special effort being made to
blend these with pure graduated SUI
gar. high grade vanilla and good ripe
fruit in the right proportion to make
dessert that is also an excellent
food
