In addition to my inspections the Sanitary Inspectors made 96 inspections of
milk premises and it is satisfactory to record that it was not found necessary to
serve notice for sanitary defects or breach of the Orders in any case.
Itinerant Milk Vendors.
In connection with the sale of milk in the Borough by itinerant vendors, it
is our practice, when such milk sellers are not registered by the Council, to
communicate with the Medical Officer of Health of the district in which the
vendor states he is registered, or in which is situated the address appearing on
the harrow, in order to obtain confirmation of registration and ascertain whether
tlui premises of the milk seller, where the milk is stored, utensils cleansed, etc.,
are in a satisfactory state.
In one such case last year, it was found that the itinerant vendor was not
registered for the address given, but as this milk seller was not again observed
selling milk in the Borough no further action could be taken.
Residue from Millt Clarifiers.
As it would seem probable that pigs have been infected with tuberculosis as
a result of feeding with infected milk and slime from clarifiers, enquiry was made
at the various establishments in the Borough where milk is cleansed by clarifiers
to ascertain what is done with the residue after the milk has been passed through
the cleansers. It was found in one case that this residue is at once destroyed by
burning in a furnace used in connection with a pasteurising plant, in a!! other cases
it is at once washed down the drains.
Bacteriological Examination of Milk.
Twenty-five samples of milk were examined for the presence of tubercle bacilli; six
of these were also examined to ascertain the number of organisms per cubic centimetre
and the smallest volume containing B. coli.
Examinations for tubercle bacilli were carried out by animal inoculation ; four of
the samples examined were found to contain tubercle bacilli.
