Milk
137 samples of graded milks were taken and submitted
to the Public Health Laboratory Service at Epsom.
Of these only one sample of pasteurised (South Devon)
milk failed the methylene blue test.
Ice Cream
These samples were graded at follows:—
Provisional Grades | 1 | 1 & 2 | 3 | 4 |
---|---|---|---|---|
Samples taken (Total 79) | 50 | 67 | 9 | 3 |
% of total samples | 63.29 | 84.80 | 11.39 | 3.79 |
No. in which Coliforms present in 1/10 ml. | 3 | 9 | 6 | 2 |
% in which Coliforms present | 6 | 13.43 | 66.66 | 66.66 |
No. in which Faecal B. Coli present | 1 | 3 | 3 | — |
% in which Faecal B. Coli present | 2 | 4.47 | 33.33 | — |
These results showed a marked improvement on
those for the previous year and there are several factors
contributing to this. A much larger proportion of the
ice cream sold in the district was wrapped, partly due,
I believe, to our activities in previous years, the increased
supplies of ice cream by reputable companies whose
names are well known and preferred by the public and
thirdly, many of the less reliable manufacturers appear to
have gone out of business or at least are not supplying ice
cream to Feltham.
In all cases notification of the results of sampling
was given to the manufacturer, the retailer and the
Authority in whose district the ice cream was manufactured,
and it was found that many manufacturers
appreciated receiving good results as well as unsatisfactory
ones.
