"With the steadily increasing recognition of the importance of clean milk and the greater insistence which distributors and the public at large are placing upon sanitary quality, it is becoming more and more incumbent on milk producers to improve the general quality of machine-drawn milk. With the hope of aiding in this direction through a study of the sanitary aspects of the milking machine problem facing Canadian producers, the investigations outlined in the present bulletin were undertaken at the Central Experimental Farm and continued from 1926 to 1928. It was planned to study the relative importance of the various factors concerned in the production of high grade milk by machine, and to compare and develop methods for the satisfactory control of bacterial contamination"--Introd., p. 4. gccst Dairy industry gccst Milk gccst Bacteriology Johns, C.
