It will be observed from the above table that nine of the eleven
samples gave unsatisfactory results.
Bacillus Coliform was present in each of these nine samples, and
excessive bacteria (exceeding 200,000 per millimetre) was present in one
sample.
Particulars relating to the unsatisfactory samples were forwarded to
the authorities concerned with the production of the milk in question and
the co-operation of their Inspectors was obtained with regard to conditions
affecting the milk supply on the producers premises.
(b) Food and Drugs Act, 1938.- Thirty-six samples of food, including
twenty-two samples of milk, were obtained for analysis. Thirty-three of
the samples were reported by the Public Analyst as being genuine. The
three unsatisfactory samples were of milk found to be deficient in fat to
the extent respectively of 5, 8 and IS per cent, of the minimum quantity
of fat proper to normal milk as indicated in the Sale of Milk Regulations.
In connection with unsatisfactory samples of milk, four " Appeal to
Cow " samples were taken by arrangement with the authority concerned,
which on analysis were found to be naturally deficient in fat, containing
2.65, 2.75, 2.80 and 2.90 per cent, respectively, thus exonerating the vendor
from the suspicion of fat extraction raised on the basis of the Regulations.
Ice Cream.—The number of premises registered for the purpose of
manufacture and sale of ice cream within the district remained at seventyeight,
but little, if any, ice cream was on sale at many of these premises
during the year.
No samples of ice cream were taken.
(c) Meat and Other Foods.—The Government meat distributing depot
was under constant supervision during the year, and a total of 322 inspections
were made. The total quantity of meat, including offal, condemned
as unfit for human consumption amounted to two tons, six hundredweights.
