3. The water supplied has no plumbo solvent action but
samples are tested for presence of metals.
4. No action has been required in respect of contamination
of the water. All water is chlorinated before distribution
and all new and repaired mains are chlorinated before being
restored to use.
5. With the exception of two or three outlying cottages, all
the houses in the area are supplied from the public water
mains. Only two houses are supplied by a common standpipe.
These two cottages, which are now condemned, are
occupied by three people.
Food Poisoning.
Fourteen unrelated cases of food poisoning have been
notified during the year. Investigations were made but the
sources of infection were not ascertained.
In addition to the above-mentioned cases, two small outbreaks
occurred at a factory canteen involving eight and
fourteen people, none of whom were actually notified. Investigations
were hampered by the paucity of evidence. In
the first incident food poisoning organisms (salm typhimurium)
were isolated from one case only and in the second
outbreak CI. Welchii which was present in nine of the
cases was thought to be the causative organism.
Establishments for Massage and Special Treatment
One establishment was licensed under Sections 355-357
of the Middlesex County Council Act, 1944.
Conclusion
In conclusion I should like to thank the members of the
Committee for the support which they have given me during
the year and also Mr. Bell and the staff of the department
for their able and willing assistance.
