Examination of Milk Samples.
Seventy-six samples of milk were submitted for examination
as follows :—
1. Pasteurised, Heat Treated and Sterilised Milk.
| Number of Samples | Phosphatase Test | Methylene Blue Test | ||
|---|---|---|---|---|
| Satisfactory | Unsatisfactory | Satisfactory | Unsatisfactory | |
| 66 | 66 | — | 61 | 5 |
2. Tuberculin Tested (Pasteurised) Milk.
| Number of Samples | Phosphatase Test | Methylene Blue Test | ||
|---|---|---|---|---|
| Satisfactory | Unsatisfactory | Satisfactory | Unsatisfactory | |
| 10 | 10 | — | 8 | 2 |
The failure of seven samples to pass the Methylene Blue
Test was due to the high atmospheric temperature when the
samples were taken in the month of September.
Samples taken in the previous month and the following
month were satisfactory.
3. Glass in School Milk.
Complaints were received that the bottled milk delivered
to a school by a local dairy contained varying amounts of
glass particles. Swift action was taken thoroughly to examine
and investigate the actual processing of milk at the dairy.
A hidden fault was discovered in the mechanism of the milk
bottle filling machine. The defect was immediately rectified
by renewal of the defective metal valve.
Further tests at the dairy and school proved the milk to
be free from the presence of glass.
ICE CREAM.
1. Registrations.
At the end of 1949, 147 premises had been registered in
accordance with Section 14 of the Food and Drugs Act, 1938.
On five of these premises ice cream could be manufactured.
