 by the Bureau of Chemistry of the U. S. Department of Agriculture in the 

 course of an investigation under the Food and Drugs Act of the milk supply 

 of a large middle western city. The methods and equipment used by 32 dealers 

 in washing cans are noted. Eight washed by pouring washing solutions from 

 one can to the next. Only one used hot water, and two clean water for wash- 

 ing. The cans were steamed in 23 dairies, but in no case was the steaming 

 effective. Three had what was considered a complete equipment, a tank with 

 mechanical brush, rinsing tank, steam jet, and air blast.
