Milk is checked for any contamination by atomic fall-out or
the carry over of antibiotics. Labels are checked for any misleading
claims.
The story goes on "Foods and Drugs Sampling" — it
must be continuous — it must keep pace with our everchanging
civilization and culture. Statistics as indicated in the appendix
can only give a glimmer of the full story.
(ii) Bacteriological
Water Supply: Seven 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
36 samples were taken during 1967 and all were found satisfactory.
Ice Cream: Samples of ice cream were taken. These were
largely from itinerant traders, for very obvious reasons.

Milk: 25 samples of milk were taken from schools, milkroundsmen
and vending machines. All were found satisfactory.
Liquid Egg: Samples were taken but difficulty was experienced
in interpreting the results of some of these. The presence of
other substances found in a bakehouse causes a sample to fail
the presribed test, but this failure doesn't mean that proper
pasteurisation has not been carried out.
The question of routine bacteriological sampling of foodstuffs
has been considered but very little has been done because
the existing public health laboratories are already overworked.
The laboratory which serves this area is at Chelmsford,
and the time-distance factor also raises further difficulties.
