FOOD AND FOOD PREMISES
33
Milk
Of the 453 samples of milk, 199 were submitted to the phosphatase
test, 214 to the methylene blue reduction test, and 23 to the turbidity
test. All these samples have been reported as complying with the
prescribed tests.
Fifteen samples of raw milk were examined for the presence of
Mycobacterium tuberculosis and Brucella abortus. In each case
negative results were obtained.
Of two samples submitted on receipt of complaints of ratepayers
both complaints were found to be justified.
Fresh Cream
Twentyfive samples were examined for the presence of pathogenic
organisms. All were reported free of contamination.
Synthetic Cream
Seventytwo samples were examined for the presence of pathogenic
organisms. All were reported free of contamination, with the exception
of two, both of which had high bacterial counts and nonfaecal
coli. These have since been rechecked and found free of
contamination.
Cake Fillings
Fortyfive samples from six shops were examined for the presence
of pathogenic organisms. Thirtynine of these were reported free
of contamination. In the remaining six staphylococcus aureus was
found. The cake fillings manufactured at the six shops have been
rechecked and found free of contamination.
Artesian Well Water
Sixteen samples were submitted for examination, eleven were
reported satisfactory, of the remaining five, all had a small plate
count and three of these contained nonfaecal coli. The five have
been rechecked and four of them are now satisfactory. The water
from the remaining well is not now being used for drinking purposes.
Icecream
During the year 80 samples of icecream were tested in accordance
with the technique suggested by the Ministry of Health and Public
Health Laboratory Service. In two cases the laboratory was unable
to carry out the methylene blue reduction test due to the presence
in the icecream of certain colouring matters. These samples were
examined at the Public Health Laboratory, Camberwell.
