Samples were procured from the Companies supplying milk under the Council’s sub¬ sidised scheme and from carts in course of delivery in the City proper. Regular weekly samples were also obtained from a metropolitan hospital. The results of the examinations show a slight improvement on the previous two years, al¬ though there is still no sign of the gradual improvement which was recorded up to the earl^ years of the war. Seventy (70) samples, or 27 per cent of the total, were higher than the standard tentatively accepted as reasonable. Three (3) samples were found to be infected with the streptococci of mastitis, whilst ten (10) showed evidence of excessive bacterial contamination. The whole of the samples submitted to the laboratory were from pasteurised milk, all of which were subjected to the phosphatase test, with the following results: No. of Complied wi th railed to RCE samples i the test Percentage comply Percentage All Sources . 257 213 83% 44 17.0% Subsidised Milk ... 84 78 92.9% 6 7.1% Metropolitan Hospital . . 44 42 95.5% 2 4.5% Carts in course of delivery and other sources 129 93 72.0% 36 28.0%
