Milk Supply
Carshalton is a Specified Area for the purposes of the Milk (Special
Designations) (Specified Areas) Order, 1951, and hence all milks sold in
the district must be "Designated" milk. The whole of Surrey is now an
"Attested Area" and the herds are presumably free from tuberculosis.
Milk Distributors
The number of Milk Distributors registered under the Milk and Dairies (General) Regulations, 1959, is 15. Designated licences issued during the year were as follows:—
| Designation | Number of Distributors Holding Licences | No. of Licences in force on 31.12.60 |
|---|---|---|
| Principal Licences — | ||
| Sterilised | 13 | 16 |
| Pasteurised | 9 | 18 |
| Tuberculin Tested | 8 | 17 |
| Supplementary Licences — | ||
| Sterilised | 6 | 10 |
| Pasteurised | 5 | 9 |
| Tuberculin Tested | 5 | 9 |
Bacteriological Examination of Milk
One hundred and seventy-two samples of milk were procured and
submitted for bacteriological examination. The milks were sold under
the Milk (Special Designations) Regulations and all complied with the
prescribed Regulations.
Classification of the milk samples and the results of the tests are as follows:—
| Designation under which sold | No. of samples | Methylene Blue Test | Phosphatase Test | Turbidity Test | |||
|---|---|---|---|---|---|---|---|
| Satisfactory | Unsatisfactory | Satisfactory | Unsatisfactory | Satisfactory | Unsatisfactory | ||
| Pasteurised | 99 | 99 | — | 99 | — | — | — |
| T.T. Pasteurised | 59 | 59 | — | 59 | — | — | — |
| Sterilised | 14 | — | — | — | 14 | ||
| 172 | 158 | — | 158 | — | 14 | ||
Biological Testing oj Milk
With the success of the campaign for the eradication of tubercle
from the herds in Surrey, it is no longer necessary to carry out biological
testing of milk except when T.T. milk is sold in the raw state. The
three farms in the district produce T.T. milk but all is heat-treated before
sale.
