Milk Supply.
There are no cowsheds or pasteurising plants in the district. All milk sold
in the district is special designated milk in sealed containers. There are four
dairies on the register and 26 persons are registered as distributors.

The following licences were issued:—

Milk Sampling.
Samples of milk submitted to chemical analysis totalled 69, and all proved
to be genuine. The samples gave the following averages:—
Fat—3.53% (standard 3.0%).
Solids not fat—8.74% (standard 8.5%).
Forty-eight samples of pasteurised milk and thirteen samples of tuberculin
tested (pasteurised) milk were submitted to the Phosphatase test and all satisfied
the test. Sixty of these samples also satisfied the Methylene Blue test, the testing
of the other sample being invalid as the atmospheric shade temperature at the time
was in excess of 65° F.
Nine samples of sterilised milk were examined and satisfied the Turbidity
Test.
Two samples of pasteurised milk were tested for tubercle bacilli with
negative results.
Ice-Cream.
There are no manufacturers in the district, but 75 premises are registered
for the sale of ice-cream, the shopkeepers obtaining their supplies from wellknown
manufacturers. In the great majority of cases the ice-cream is delivered
to the premises and sold in cartons or wrapped.
Forty-seven samples of ice-cream were taken and submitted to the
Methylene Blue test with the following results:—
Grade 1—28; Grade 2—16; Grade 3—nil; Grade 4—3.
Where samples were found to be in Grade 4 the dealers concerned were
given advice regarding precautions to be observed and in each case subsequent
samples were found to be satisfactory. In no case was ice-cream found to be
stored at a temperature exceeding 28° Fahrenheit.
