260 Principles of Legislative Milk Control. 



perature to 45 F. shall be used, and aerators shall be so situated 

 that they can be protected from flies, dust, and odors. The milk 

 shall be cooled immediately after being milked, and maintained 

 at a temperature between 35 and 45 F. until delivered to the 

 consumer. 



37. Sealing of bottles. Milk, after being cooled and bottled, 

 shall be immediately sealed in a manner satisfactory to the com- 

 mission, but such seal shall include a sterile hood which com- 

 pletely covers the lip of the bottle. 



38. Cleaning and sterilizing of bottles. The dairy building 

 shall be provided with approved apparatus for the cleansing and 

 sterilizing of all bottles and utensils used in milk production. 

 All bottles and utensils shall be thoroughly cleaned by hot water 

 and sal soda, or equally pure agent, rinsed until the cleaning 

 water is thoroughly removed, then exposed to live steam or boil- 

 ing water at least 20 minutes, and then kept inverted until used, 

 in a place free from dust and other contaminating materials. 



39. Utensils. All utensils shall be so constructed as to be 

 easily cleaned. The milk pail should preferably have an elliptical 

 opening 5 by 7 inches in diameter. The cover of this pail should 

 be so convex as to make the entire interior of the pail visible and 

 accessible for cleaning. The pail shall be made of heavy seamless 

 tin, and with seams which are flushed and made smooth by solder. 

 Wooden pails, galvanized-iron pails, or pails made of rough, 

 porous materials, are forbidden. All utensils used in milking 

 shall be kept in good repair. 



40. Water supply. The entire water supply shall be abso- 

 lutely free from contamination, and shall be sufficient for all dairy 

 purposes. It shall be protected against flood or surface drainage, 

 and shall be conveniently situated in relation to the milk house. 



41. Privies, etc., in relation to water supply. Privies, pig- 

 pens, manure piles, and all other possible sources of contamina- 

 tion shall be so situated on the farm as to render impossible the 

 contamination of the water supply, and shall be so protected by 

 use of screens and other measures as to prevent their becoming 

 breeding grounds for flies. 



42. Toilet rooms. Toilet facilities for the milkers shall be 

 provided and located outside of the stable or milk house. These 

 toilets shall be properly screened, shall be kept clean, and shall 

 be accessible to wash basins, water, nail brush, soap and towels, 

 and the milkers shall be required to wash and dry their hands 

 immediately after leaving the toilet room. 



Transportation. 



43. In transit the milk packages shall be kept free from dust 

 and dirt. The wagon, trays, and crates shall be kept scrupulously 

 clean. No bottles shall be collected from houses in which com- 

 municable diseases prevail, unless a separate wagon is used and
