MILK SUPPLY
Food and Drugs (Milk Dairies and Artificial
Cream Act 1950
Milk and Dairies Regulations 1949
The Milk (Special Designation) (Raw Milk)
Regulations IPh9
The Milk (Special Designation) (Pasteurised
and Sterilised Milk) Regulations 1969
Routine Inspection of milk pasteuriser's, dealers and
vendors premises has again revealed that the provisions of the
various Regulations are generally well observed.
The following licences to sell graded milks In the Borough were granted In 1951:-
| TYPE OF LICENCE | ||||
|---|---|---|---|---|
| Grade of Milk | Dealers Supplementary Pasteuriser's | |||
| Tuberculin Tested | 11 | 8 | - | |
| Tuberculin Tested (Past) | 6 | 2 | - | |
| Pasteurised | 19 | 10 | 2 | |
| Sterilised | 25 | 12 | - | |
| Total | 61 | 32 | 2 | |
Examination of Milk Samples
One hundred and two samples of milk were submitted for examination as follows:-
| Class of mine | No. of sair®les taken | Test applied | Number of samples | |
|---|---|---|---|---|
| Passed | Failed | |||
| Pasteurised | 62 | Phosphatase | 61 | 1 |
| Methylene Blue | 61 | 1 | ||
| Sterilised | 7 | Turbidity | 7 | - |
| Tuberculin Tested (Pasteurised) | 17 | Phosphatase | 17 | _ |
| Methylene Blue | 17 | - | ||
| Tuberculin Tested (Farm bottled) | 16 | Methylene Blue | 14 | 2 |
| TOTAL | 102 | 4 | ||
It will be noted that all samples of Tuberculin Tested and
Sterilised milks passed the prescribed tests. The failure of one
Pasteurised milk sample and two Tuberculin Tested (Farm Bottled)
Milk samples to pass the Methylene Blue Test was mainly due to
the high atmospheric temperature at the time the samples were
taken. It would appear that a further contributory cause In the
case of the farm bottled milk was the delay between the time of
production and delivery to the dairy.
