29 samples of milk were submitted to the County
Laboratory as follows :—
| Tuberculin Tested Pasteurised | 10 |
| Pasteurised | 11 |
| Sterilised | 8 |
Of these, 1 pasteurised and 2 tuberculin tested pasteurised
failed to satisfy the Methylene Blue Test.
The Dairies concerned were contacted and their attention
drawn to the unsatisfactory results.
Although these samples were procurred during the morning
delivery, it was thought that the time lag between
pasteurisation and delivery may have had some bearing on
the result, and the suppliers were asked to investigate the
matter from this angle.
Since then all samples from the same source have satisfied
the tests.
ICE CREAM (HEAT TREATMENT) REGULATIONS,
1947—1952.
There is only one manufacturer of ice cream in the
area, and as a complete cold mix is used, heat treatment is
not necessary.
40 samples of ice cream submitted for examination during the year were graded as follows:—
| Grade 1 | 32 |
| Grade II | 4 |
| Grade III | 3 |
| Grade IV | 1 |
In the case of the Grade IV sample, which concerned
ice cream manufactured from a complete cold mix, a visit
was paid to the premises and the method of manufacture and
storage checked. Advice was given to the manufacturer and
as a result subsequent samples showed considerable improvement,
the bulk of them being Grade I.
