MILK SUPPLY
Food and Drugs (Milk Dairies and Artificial Cream)
Act 1950
Milk and Dairies Regulations 1949
The Milk (Special Designation) (Raw Milk)
Re gulations 1949
The Milk (Special Designation) (Pasteurised
and Sterilised Milk) Regulations 1949
Routine inspection of milk pasteuriser's and distributor's
premises reveals that the provisions of the various Regulations
are generally well observed.
The following licences to sell graded milks in the Borough were granted in 1952:-
| Grade of Milk | TYPE OF LICENCE | ||
|---|---|---|---|
| Dealers | Supplementary | Pasteuriser's | |
| Tuberculin Tested | 9 | 10 | - |
| Tuberculin Tested (Past) | 9 | - | |
| Pasteurised | 19 | 11 | 2 |
| Sterilised | 35 | 12 | - |
| 72 | 33 | ||
Examination of Milk Samples. One hundred and eighteen samples of milk were submitted for examination as follows:-
| Class of milk | No. of samples examined | Test applied | Number of Samples | |
|---|---|---|---|---|
| Passed | Failed | |||
| Pasteurised | 64 | Phosphatase | 64 | - |
| Methylene Blue | 64 | - | ||
| Sterilised | 7 | Turbidity | 7 | - |
| Tuberculin Tested (Pasteurised) | 15 | Phosphatase | 15 | - |
| Methylene Blue | 14 | 1 | ||
| Tuberculin Tested (Farm Bottled) | 32 | Methylene Blue | 25 | 7 |
| 118 | ||||
All Pasteurised and Sterilised Milks passed the prescribed
Tests. One Tuberculin Tested (Pasteurised) sample and seven
Tuberculin Tested (Farm Bottled) samples failed to pass the
Methylene Blue Test. Once again it would appear that the main
contributing factors to the failures were the high atmospheric
temperature when the samples were taken and the period between
the time of production and delivery of the farm bottled milk.
