Normally a supply of pasteurised milk is insisted upon if such is available. Failing this tuberculin tested milk is approved. School milk supplies are sampled regularly, every supply being sampled at least twice a term, and every school sampled at least once each year. Raw milks are examined bacteriologically (for cleanliness) and biologically (for the presence of tubercle bacilU and brucella organisms). Pasteurised milks are submitted to the Phosphatase test for the efficiency of the pasteurising process and the Methylene Blue test for cleanliness. In the case of unsatisfactory samples of raw milk the supplier and/or the producer are notified together with the Divisional Milk Officer of the Ministry of Agriculture, Fisheries and Food. Repeat samples are taken and failing any improvement alternative suppliers are found. Unsatisfactory samples of pasteurised milk processed at dairies licensed by the County Council are investigated by the County Health Inspectors for both Methylene Blue and Phosphatase test failures. Where the dairy is not licensed by the County Council, samples failures are re¬ ported to the Medical Officer of Health of the licensing authority con¬ cerned for appropriate action. One thousand and eighty-five samples were collected from schools during 1962. The following table shows the results of tests carried out:— Samples examined Passed Failed Methylene Blue test 1,085 1,036 43 (9 T.T. (6 void due to high 2 T.T. (Pasteur- atmospheric shade ised) temperature) 32 Pasteurised) Phosphatase test 1,024 1,024 Nil Biological examination a) Tubercle bacilli 45 45 Nil b) Brucella abortus 45 44 1 Once again it is pleasing to note that none was found positive for tubercle, and in fact there have been no positive samples since 1953. One sample of raw T.T. milk was reported to be infected with Brucella abortus. An alternative supply of milk to the school was arranged immediately until resampling showed the milk to be satisfactory. The same procedure was adopted in the case of another school milk supplier when a retail (“Street”) sample was found to be infected with Brucella abortus but in this case a permanent alternative supply of pasteurised milk was arranged.
