It would seem that the low incidence of unsatisfactory samples is indicative
that manufacturers, importers and traders of food and drugs in this country
are kept aware of their responsibilities by the surveillance of the sampling legislation
and procedures.
(ii) Bacteriological
Water Supply: Five samples of water supplied to the Borough by the Metropolitan
Water Board and the South Essex Waterworks Company were taken and
found satisfactory.
Swimming Baths: Monthly samples from the Public Swimming Baths and
those in our schools were taken in order to ensure that they were suitable for
the purpose of swimming. A total of 63 samples were taken during 1969 and all
were found satisfactory.
In addition, numerous bath-side tests for PH and chlorine content were
made with the Lovibond comparator.

Milk: 33 samples of milk were taken from school*, milk-roundsmen and
vending machines. Two samples of pasteurised milk failed the Methylene Blue
Reduction test.
(c) Inspection of Food:
The constant inspection of food premises whether retail, wholesale, manufacturing
or hawkers has been maintained during the year to ensure that food for
sale or manufacture or preparation for sale is fit for human consumption.
There ate no slaughter houses or knackers yards within the borough, but
there are several large wholesale food depots, and a meat depot and cold store.
Very frequent inspections are made of these premises.
With the growth of "container* food traffic from the continent, the duties of
the public health inspectors under the Imported Food Regulations is likely to
increase. Inspections previously carried out by port health inspectors are now
being carried out at the destination of the "container*, usually a wholesale food
depot.
