MILK SAMPLES
Twenty-one samples of milk were submitted for bacteriological examination as below:-
1. Pasteurised Milk.
| No.of Samples | Below 100,000 bacteria per millilitre 9 | Coliform Test | Phosphatase Test | ||
|---|---|---|---|---|---|
| Satisfactory | Unsatisfactory | ||||
| 9 | Above 100,000" bacteria per millilitre | 5 | 4 | 9 | - |
2. Tuberculin Tested (Pasteurised)
| No. of Samples | Below 30,000 bacteria per millilitre 1 | Coliform Test | Phosphatase Test | ||
|---|---|---|---|---|---|
| - | - | Satisfactory | Unsatisfactory | ||
| 3 | Above 30,000 bacteria per millilitre 2 | 2 | 1 | 3 | - |
3. Ordinary Milk
| No, of Samples | Total bacteria per millilitre | Coliform test | ||||
|---|---|---|---|---|---|---|
| Under 50,000 | 50,000-100,000 | Over 1,000,000 | - | - | ||
| 9 | 6 | 2 | 1 | 6 | 3 | |
The Methylene Blue (Reductase) Test was satisfactory in all
but one of the 21 samples.
The "Ordinary" milk samples were from flash pasteurised or
pasteurised (unlicensed) supplies. In these cases the
phosphatase test was not satisfied in two samples of the flash
pasteurised milk. With these two exceptions the presence of
B. Coli in all the samples appears to be due to postpasteurising
processes.
ICE CREAM
At the end of 1944, 106 premises had been registered in
accordance with Section 14 of the Pood and Drugs Act, 1938.
On ten of these premises ice cream could be manufactured.
Owing to the war-time ban upon the manufacture and sale of
ice-cream it was not necessary to visit these premises during
1944. In view of the removal of this ban at the end of the
year a resumption of the inspections will take place in 1945
and the Register will be revised.
