Dairies, Cowsheds and Milkshops.
The number of registered dairies and milkshops in the Borough at the end of the
year was 129. Seven retail dairies and milkshops were newly registered, and two
removed from the register. In eight other cases alterations in the register became
of necessary on change to ownership.
In addition to my inspections the Sanitary Inspectors made 98 inspections of
these premises. No notice had to be served for sanitary defects or breaches of
regulations.
From time to time itinerant vendors, other than those registered in connection
with premises within the Borough area, sell milk in the Borough. In these cases it
is our practice to communicate with the Medical Officer of Health of the district
from which the itinerant dealer comes in order to ascertain that the milkseller is
registered as required by the Milk and Dairies Order.
Residue from Milk 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; five
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.
