(b) Licences in respect of premises in the Borough

(c) Supplementary licences to sell milk from
premises outside the Borough 7
During the year, 189 samples of specially designated milk were
purchased and submitted to bacteriological examination for the
purpose of ascertaining whether they conformed to the standards
laid down in the Order. Fifteen samples of "Pasteurised," two
of "Tuberculin Tested," one of "T.T. (Certified)" and one of "T.T.
(Pasteurised)" milk did not conform to the standards for these
grades of milk. The vendors concerned furnished explanations,
which were accepted, as to why the milk did not conform to the
standards. Further samples of milk obtained from these firms at
later dates proved to be satisfactory.
In addition to the examination of Pasteurised milk mentioned
above, all samples of this grade of milk are examined by the
Phosphatase Test for efficiency of Pasteurisation, and samples
reported positive by this test are specially examined for the presence
of Tubercle Bacilli. Thirty-seven samples were so examined during
the year with a negative result in each case.
Milk Supplied to Hospitals and Schools.—Samples of the milk
supplied to the London County Council's hospitals and schools in
the Borough are taken periodically and submitted to bacteriological
or chemical examination.
