SECTION E—WATER SUPPLY—MILK—FOOD AND
DRUGS ACT—FOOD INSPECTION
E (1) Water supply
The Borough is served throughout by the Metropolitan
Water Board, the water containing some 30.8 degrees of
hardness.
Almost without exception, the supply is led direct into
the premises served. Two monthly samples have been forwarded
to the appropriate Laboratory for bacteriological
examination, with satisfactory results.
The former chemical accretion in water service pipes at
Coronation Court and which was characterised by green and
blue discolouration in kettles due to the deposition of calcium
carbonate coloured by the small admixture of copper carbonate,
now appears to be wholly neutralized. The copper
carbonate content was attributed to the new lead, galvanised
iron, and copper service pipes, and the gradual build up
of calcium carbonate in the interior of the pipes seems to
have mitigated the discolouration. Samples of water at this
source now produce satisfactory results.
E (2) Milk supply
E(2)a Food and Drugs Act 1955. Section 37. The Milk
(Special Designations) (Specified areas) Order 1951.
By virtue of the above Order which came into operation
on 1st October, 1951, all the milk supply is specially
designated.
During the summer, it was found that the overlapping
caps on bottles utilised by one dairy company were so faintly
franked that the appropriate designation was very difficult
to discern. The matter was immediately brought to the notice
of the company concerned as a result of which an improvement
was effected with regard to the franking of designations
on caps.
E 2(b) The Milk (Special Designation) (Raw Milk) Regulations,
1949 and 1954. The Milk (Special Designation)
(Pasteurised and Sterilised Milk) Regulations, 1949 to 1953.
The designations applicable to milk sold in the
Borough are limited to "Pasteurised," "Sterilised." and
"Tuberculin Tested." Pasteurised milk must be bottled at
the premises at which it is heat treated. There are no pasteurisers
and milk bottling establishments situated in the Boroug
