(a) A sample taken at any time during the period from 1st May to
31st October inclusive shall be kept at atmospheric shade temperature
until 9.30 a m on the following day
(b) A sample taken at any time during the period from 1st November to
30th April inclusive shall be kept in its original container, or in a sterile
3oz sample bottle at atmospheric shade temperature until 5 0 p.m. on the
day of sampling and thereafter at a constant temperature of 65°F+ 2°F
until 9.30 a m on the following day.
The Methylene Blue test shall be begun between 9.30 a.m. and 10,0 a.m.
on the day after the sample is taken, but the test shall NOT be applied if
during the period of storage at atmospheric shade temperature this
temperature at any time exceeds 70°F, The test shall be deemed to be
satisfied by milk which fails to decolourise methylene blue in thirty
minutes.
Six samples of Tuberculin Tested (Farm Bottled) Milk failed the test.
The dairy companies concerned were notified immediately of the failures in
order that the matter could be taken up with the responsible producers as
speedily as possible
The 'Phosphatase' test for Pasteurised Milk shall be deemed to be
satisfied by milk which gives a reading of 10 ug or less of p-nitrophenol/ml
of milk Seventy eight samples were subjected to this test and found to be
satisfactory.
CHEMICAL ANALYSIS OF MILK AND CREAM SAMPLES
MILK
Forty-two formal and twenty-five informal samples of milk were taken
for chemical analysis: all were found to be genuine
Seventeen samples of 'Channel Island' milk contained satisfactory
averages of 4 64% milk fat and 8.99% milk solids other than milk fat; fifty
other samples of milk contained satisfactory averages of 3 66% milk fat
and 8.71% milk solids other than milk fat
The results were well above the minimum standard of 4% milk fat
laid down in the Milk and Dairies (Channel Islands and South Devon Milk)
Regulations 1956; and of 3% milk fat and 8.5% milk solids other than milk
fat required under The Sale of Milk Regulations, 1939.
