Routine inspection of all dairy farms in the milk shed is maintained, and all possible assistance is given where the dairy farmer may be having difficulty in meeting our standards. LABORATORY REPORT The number of retail bottled samples taken during the year either from delivery wagons or at the plants was 523. These samples were examined for butterfat content, solids-not-fat, sediment and flavor. Methylene blue tests were also run on them. Over half the samples were submitted to test for bacteria count and all those exceeding 50,000 given a re-test as soon as possible. The pasteurized milk was also tested at least twice a month by means of the phosphatase test to ensure adequacy of pasteurization. The results of these tests are shown in tabular form. In the first table the bacterial results of all retail samples are classified. The ten examinations which were spoiled by the growth of spreaders are excluded in arriving at the proportion in each group.
