61 samples were taken for bacteriological test, 4 of which did not comply with the prescribed conditions.
The Express Dairy Co., Ltd., to whom the Pasteuriser's Licence was issued, ceased to use their premises at 163,
Harrow Road in the latter part of the year for the heat treatment of milk.
Ice Cream.—The Ice Cream (Heat Treatment etc.) Regulations came into operation on the 1st May, 1947. In brief,
these require that the ingredients of ice cream shall be heat treated after being mixed, and that the mixture shall be cooled
until the freezing process is begun. After freezing, the ice cream must not be sold unless it has been kept
at a temperature of not more than 28°F.; but if its temperature has risen above 28°F. it must be heat treated again
and then be kept at not more than 28°F. after having been frozen. This, however, does not apply to what is known
as a "complete cold mix." Thermometers are required to be used for indicating and recording temperatures. It is
not yet possible to enforce this requirement owing to the difficulty of obtaining the instruments.
No bacteriological standard of cleanliness has been provided for in the Regulations, there being still no reliable
test which would justify its use in law. A form of the methylene blue test has, however, been adapted for testing ice
cream for bacterial cleanliness, and if, out of the four grades recommended, ice cream fails consistently to reach grades
I and II, it is considered reasonable to presume defects of manufacture or handling calling for investigation.

WORK OF THE LADY SANITARY INSPECTORS.—
Infectious Disease.—The two Lady Sanitary Inspectors visit cases of infectious disease other than typhus, smallpox,
puerperal fever and pyrexia, infective enteritis, summer diarrhoea and tuberculosis, and one of them also acts in a
supervisory capacity at the medicinal baths. The following table gives an indication of the nature of their work.
