Hampstead Heath Fair.
As usual members of the Inspectorial staff and their assistants were
on duty throughout the Easter, Whitsun and August Bank Holiday fairs.
Some idea of the intensive work involved in sampling alone on these
fair days may be gauged from the fact that no less than 101 articles of
food and drink were submitted to bacteriological examination and 79 to
chemical analysis. Included in these figures are 38 samples of Ice-cream
which were submitted to the "Methylene Blue" test. It is interesting
to compare the improvements over the years since more intensive
inspection began as illustrated by the following table: —

These results are significant in the light of the gradually improving
hygienic conditions we have been able to secure over the period since
1948, viz.:-
