MILK SUPPLY (Cont.)
3. Milk Sampling - (Cont)
All samples conformed to the required standard, except one
sample of tuberculin tested milk from a vending machine which had
failed the methylene blue test. This failure was taken up with
the producer concerned and check samples taken. The explanation
was an error in servicing the machine by a relief worker during the
holiday period. The Council decided that a warning letter be sent
to the producer concerned.
The phosphatase test indicates that pasteurisation has been
properly carried out; the methylene blue test is used to determine
cleanliness and keeping quality; the turbidity test is a check on
sterilisation and the T.B. test ia for the purpose of detecting
tubercle bacilli. 12 of the T.B.(Raw Milk; samples for T.B. test
were taken at farms in the Borough.

The Public Health Laboratory Service advises that owing to
the numerous factors governing the hygienic quality of ice cream
it is unwise to pay too much attention to the bacteriological
results on any single sample. Judgment should be based rather
on a series of samples. It is suggested that over a six monthly
Period, 50% of a vendor's samples should fall into grade 1,80%
into grades 1 or 2, not more than 20% into grade 3 and none into
grade 4.
The results above show that a very high standard of hygienic
quality is being maintained both by manufacturers and retailers.
There is now no ice cream manufactured within the Borough.
