EXAMINATION OF MILK.
(A) Chemical.—Nine samples, all of which were procured formally, were found to be
adulterated, giving a percentage of milk adulteration of 3.0 compared with 5.7 for 1924.
There were two prosecutions and penalties were imposed in each case, and in seven instances
the vendors were cautioned.
The following table shows the percentage of fat contained in each of the 295 samples
of milk examined. Three out of this number contained fat in amounts below the point which
presumes adulteration, i.e., 3 per cent. The highest amount of fat contained in any sample
was 6 .9 per cent. :—

The practice of making special enquiries with reference to the samples which contained
a percentage of fat exceeding 4.2 has been continued. Fourteen were of milk obtained in
the course of delivery at Railway Stations, four of which were from Jersey cows and the
amount of fat, therefore, was not excessive. Nine samples were taken from shop counter
pans and it is more than probable that neglect of proper stirring by the retailer accounted
for the excessive fat content.
THE PUBLIC HEALTH (CONDENSED MILK) REGULATIONS, 1923.
Forty samples of condensed milk were taken and submitted to the Public Analyst.
Thirty-four separate Brands were examined, as follows :—
Condensed Full Cream Milk Sweetened 10
Condensed Skimmed or Machine Skimmed Milk Sweetened 27
Condensed Skimmed Milk Unsweetened 1
Condensed Full Cream Milk Unsweetened 2

In no instance was the condensed milk found to be below the required standard, but in
three cases the labels were not in conformity with the Regulations.
PUBLIC HEALTH (MILK AND CREAM) REGULATIONS, 1912 & 1917.
During 1925, 295 samples of Milk were examined under these Regulations, and all were
found to be free from preservative.
Eleven samples of cream (not preserved) were purchased, four of which were certified to
contain Boric Acid and in no instance was the amount in excess of that permitted by the
Regulations for Preserved Cream. Of these four samples, two were informal, and two formal,
purchased from the same vendors respectively. Explanations in each case were submitted
to the effect that through inadvertance a declaration was omitted from the bill of fare.
Fourteen samples of Preserved Cream were obtained and found to comply with the
Regulations as to labelling and the amount of preservative permitted.
In no instance did the fat content of Preserved Cream fall below 35 per cent.
No contravention of the other requirements relating to preserved cream was found.
All the samples of Cream and Preserved Cream were certified to be free from thickening
substances.
