actual production of milk, and for licensing for the sale of Designated Milks.
Eighteen samples of milk have been taken, in course of delivery to the consumer, and submitted to the appropriate tests with the following results:-
| Designation | Samples Taken | Satisfactory | Unsatisfactory |
|---|---|---|---|
| Tuberculin Tested (Pasteurised) | 2 | 2 | Nil |
| Pasteurised | 11 | 10 | 1 |
| Pasteurised (Homogenised) | 2 | 2 | Nil |
| Pasteurised (Channel Islands) | 2 | 2 | Nil |
| Sterilised | 1 | 1 | Nil |
| Totals | 18 | 17 | 1 |
Regarding the one unsatisfactory sample, this satisfied the Phosphatase Test,
indicating that it has been properly processed, "but failed the Methylene Blue Test.
This would emply undue bacterial activity.
The matter was taken up with the Dairy Company concerned, who offered as
explanation that, by some mischance, the milk had been of a previous day's delivery
which should not have been re-issued to the roundsman. Further check samples
were satisfactory.
No official action was taken under Regulation 20 of the Milk and Dairies General
Regulations 1959, to stop or restrict the sale of milk.
No cases of disease were notified which could be attributed to the consumption
of infected milk.
Eleven Dealer's Licences and twenty-one Supplementary Licences were granted for the retail sale of milk under the Milk (Special Designation) (Raw Milk) Regulations, 1949 and 1950, and the Milk (Special Designation) (Pasteurised and Sterilised Milk) Regulations, 194-9 and 1950, viz:-
| I Designation | Dealer's Licences. | Supplementary Licences. |
|---|---|---|
| Tuberculin Tested | 3 | 7 |
