Milk Sampling.
Samples of milk submitted to chemical analysis totalled 60 and all proved
to be genuine. The samples gave the following averages:—
Fat—3.54% (standard 3.0%).
Solids not fat—8.85% (standard 8.5%).
Thirty-seven samples of pasteurised milk and fourteen samples of tuberculin
tested (pasteurised) milk were submitted to the Phosphatase test and they
all satisfied the test. Forty-five of these samples also satisfied the Methylene
Blue test, the testing of the other six samples 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.
Ice-Cream.
There are no manufacturers in the district, but a large number of premises
are registered for the sale of ice-cream, the shopkeepers obtaining their supplies
from well-known manufacturers. In the great majority of cases the ice-cream is
delivered to the premises and sold in cartons or wrapped.
Sixty-seven samples of ice-cream were taken and submitted to the
Methylene Blue test with the following results:—
Grade 1—54; Grade 2—8; Grade 3—4; Grade A—1.
Where samples were found to be in Grades 3 or 4 the dealers concerned
were given advice regarding precautions to be observed and in each case subsequent
samples were found to be satisfactory.
Slaughterhouses.
No animals were slaughtered in the district.
