Examination of Milk Samples
One hundred and nine samples of milk were submitted for examination as follows
| Class of Milk. | Number of samples taken | Appropriate test applied | Number of Passed | samples Failed |
|---|---|---|---|---|
| Pasteurised | 77 | Phosphatase | 77 | - |
| Sterilised | 10 | Methylene Blue | 73 | 4 |
| Turbidity | * 10 | - | ||
| Tuberculin Teste (Pasteurised) | d 12 | Phosphatase | 12 | - |
| Methylene Blue | 12 | - | ||
| Tuberculin Teste (Farm Bottled) | d 10 | Methylene Blue | 3 | 7 |
| Total | 109 | 11 |
It will be noted that all the Pasteurised and Tuberculin
Tested (Pasteurised) Milks passed the phosphatase test and the
sterilised milks the turbidity test.
The failure of eleven samples to pass the methylene blue
test was mainly due to the high atmospheric temperature at the
time the samples were taken and in the case of one producer of
Tuberculin Tested (Farm Bottled) milk to the delay between the
time of production and delivery to the customer These
factors had an adverse effect upon the keeping qualities of
the milk. However, when further samples were taken the results
proved to be satisfactory.
