amongst his staff or customers must be reported to me immediately it came to his
notice. No case was so reported.
The herd at the farm was later examined by a Veterinary Surgeon and declared
to be healthy, and the supply of milk to the City was consequently resumed.
No further case of a similar nature came to my notice during the year.
PUBLIC HEALTH (MILK AND CREAM) REGULATIONS, 1912 AND 1917.
REPORT FOR THE YEAR ENDED 31st DECEMBER, 1922.
From the subjoined table it will be noted that of the 219 samples of milk
purchased within the City in no instance did the Analyst report that a preservative
had been added, neither did he indicate the addition of any colouring matter.
In no instance were " appeal to cow " samples obtained.
13 samples of cream were purchased in addition to the milk samples for examination
under the Milk and Cream Regulations, 1912 and 1917. Six of these
samples were purchased as cream (not preserved cream). On examination it was
found that in two instances such cream did actually contain preservative, namely,
boric acid. The purchases were made from the same shop, the first one having been
purchased informally, and in consequence of the small amount of preservative
discovered a second formal sample was taken. One of these contained 0.18 per
cent. and the other half that amount. The explanation submitted by the vendor
was accepted and no proceedings resulted.
Seven samples of preserved cream were obtained and in all instances the cream
was found to contain above 35 per cent. of fat. In two instances, however, the
amount of preservative was found to exceed that permitted by the Regulations
but not to any very serious extent. In both instances it was below 0.5 per cent.,
which was the former standard.
In one of these instances the seller still retained on his announcements the
percentage 05 per cent. which was permitted by previous regulations.
It will be remembered that the amount now permissible is 0.4 per cent.
Explanations were sought and were accepted by the Committee.
In no instance was evidence discovered of the addition of a thickening substance
to cream.
