HYGIENE OF FOOD
Food Poisoning
Of the 9 cases notified as food poisoning, 5 were confirmed bacteriologically as Salmonella
Typhimurium. Three of these cases occurred in one family.
Personal Hygiene
The free washing facilities in the public conveniences, which were brought into operation
in September, 1950, continued to be available throughout 1958. During that period 10,100
paper towels were issued free, and also 3,626 linen towels, which were provided at a cost of
2d. per person.
Milk
The following licences under the Milk (Special Designation) (Raw Milk) Regulations,
1949 and 1950, and Milk (Special Designation) (Pasteurised and Sterilised Milk) Regulations,
1949 and 1950, were issued:—
for the sale of Tuberculin Tested Milk 22
for the sale of Pasteurised Milk 25
for the sale of Sterilised Milk 23
Supplementary Licences 18
88
Ice Cream
The Ice Cream (Heat Treatment, etc.) Regulations, 1947-1952. As there were no
manufacturers in the Borough, temperature control observations, as laid down in these
Regulations, were not required. Routine work was carried out under Article 4 of the 1947
Regulations to check the conservation of ice-cream in cinemas.
Food Sampling
The bacteriological analyses of 202 food samples, taken during the year, were carried
out by the Public Health Laboratory Service.
156 of these specimens were ice-cream samples, covering 9 makes of ice-cream, and
following bacteriological analyses the ice-creams were graded as follows:—
Excellent 73
Satisfactory 56
Doubtful 6
Unsatisfactory 21
In the Ealing Laboratory, which serves the Department for bacteriological investigations,
the standard is bacteriological, whereas over the rest of the county the standard is a chemical
one, the Methylene Blue Test. Our tests are more exacting, and although comparatively we
may show worse figures, in fact we are applying better control.
44 samples were taken of Imitation Cream. The results of these were all satisfactory.
Two samples of Pork Brawn and two samples of cooked mutton were tested. All were
satisfactory.
One sample of domestic tank water, and three samples of water from the Paddling Pool
were tested during the year. All tests were satisfactory.
