During the year 42 samples of milk were sent to the Public Health Laboratory at Epsom and the following is a tabulated statement of the results:-
| Phosphatase Test | Methylene Blue Test | Turbidity Test | |||||
|---|---|---|---|---|---|---|---|
| Pass | Fail | Pass | Fail | Void | Pass | Fail | |
| Pasteurised | 34 | *34 | 3 | 3 | — | ||
| Sterilised | 2 | ||||||
*Including 11 samples which passed the modified
Methylene Blue Test for dispensers.
The three samples shown as void were due to the atmospheric
shade temperature during the period of storage exceeding 70 F. so
that the methylene blue test was not applied.
