The Milk (Special Designations) (Specified Area) Order 1951
came into operation on the 1st October, 1951, and from that date
all milk sold by retail in the Borough must be "designated milk,"
i.e., Tuberculin Tested, Pasteurised or Sterilised Milk.
Sixty-three samples of milk and cream were taken and submitted
to the Methylene Blue and Phosphatase Tests at the Public
Health Laboratory, Ealing.
The results were as follows:
| Designation | Samples | Phosphatase | Methylene Blue | ||
|---|---|---|---|---|---|
| Passed | Failed | Passed | Failed | ||
| Pasteurised | 49 | 46 | 3 | 49 | — |
| T.T. Pasteurised | 2 | 2 | — | 2 | — |
| Heat Treated ... | 5 | 4 | 1 | 5 | — |
| Undesignated ... | 5 | 4 | 1 | 5 | — |
| Cream | 2 | 2 | — | 2 | — |
| 63 | 58 | 5 | 63 | — | |
Subsequent samples were taken from the suppliers of the 5
samples which failed the Phosphatase Test, and these proved
satisfactory.
In addition, 250 samples of Pasteurised Milk from processing
plants in the Borough were taken by the Officers of the County
Council who are the licensing authority under the Milk (Special
Designations) Regulations. Of these 12 failed the Methylene Blue
Test and 2 failed the Phosphatase Test.
Ice Cream.
The 293 registered ice cream premises in the Borough were
all visited during the year and the source of supply checked. It
was found that their ice cream is obtained from one of the 7
registered manufacturers in the Borough or of the 24 manufacturers
from outside the Borough. Samples from each of these 31 manufacturers
were taken once or more during the year, a total of 103
samples of ice cream, ice cream constituents and ice lollies being
submitted for bacteriological examination.
