The production of sanitary milk. — A study of the production of 

 sanitary milk and of the relations of the consuming public to this 

 production have received much attention during the past two or 

 three years. It seems to be very important in the interests of the 

 economy of production to know what factors in the drawing and 

 handling of milk have the most influence upon its germ content. 

 It is, of course, essential that dairy animals be healthy and that 

 persons dangerous to the sanitary quality of the milk be not per- 

 mitted in the stable, or be in any way connected with the handling 

 of milk. The studies that have been carried on by the Station have 

 pertained rather to barn conditions. Conclusions as to the effect of 

 the use of small-mouthed pails for milking, and of the milking 

 machine, upon the germ content of the milk, have been presented 

 in former reports. 



In Bulletin No. 365 are shown the results of studies on the 

 effect of protecting the milk pails from accidental contamination 

 after they have been thoroughly steamed; of whitewashing, and 

 otherwise thoroughly renovating the interior of the stable; of clip- 

 ping the udder, flank and adjoining portions of the cow; of cleaning 

 the cow with a vacuum cleaner at the rate of one cow per minute, 

 as compared with hand-cleaning at the rate of two cows per 

 minute, and of cooling and straining the milk.
