RAW MILK SUPPLIES - BRUCELLA ABORTUS
There is only one farm engaged in milk production in the borough. As a result of a
a request from the Public Health Laboratory Service, sampling of raw milk for the
detection of brucella abortus organisms was carried out directly from the farm during
1969. A total of 10 samples was taken and all were found to be negative for this
organism by the ring test.
ICE CREAM
During the year 9 premises were added to the register for the sale and storage of
ice cream, leaving a total at the end of the year of 498 premises registered for sale
and storage and seven premises for manufacture.
Throughout the year, routine inspections at regular intervals were made to manufacturers' premises to ensure compliance with the requirements of the Pood Hygiene and Ice Cream (Heat Treatment) Regulations. Systematic sampling of ice cream and ice lollies was carried out, details of which are as follows:-
