CERTIFIED MILK 499 



into the barn only immediately before the feeding hour, which shall follow the 

 milking. 



18. Only those foods shall be used which consist of fresh, palatable, or 

 nutritious materials, such as will not injure the health of the cows or un- 

 favorably affect the taste or character of the milk. Any dirty or moldy food 

 or food in a state of decomposition or putrefaction shall not be given. 



19. A well-balanced ration shall be used, and all changes of food shall be 

 made slowly. The first feedings of grass, alfalfa, ensilage, green corn, or other 

 green feeds shall be given in small rations and increased gradually to full ration. 



20. Exercise. All dairy cows shall be turned out for exercise at least two 

 hours in each twenty-four in suitable weather. Exercise yards shall be kept 

 free from manure and other filth. 



21. Washing of Hands. Conveniently located facilities shall be provided 

 for the milkers to wash in before and during milking. 



22. The hands of the milkers shall be thoroughly washed with soap, 

 water, and brush and carefully dried on a clean towel immediately before 

 milking. The hands of the milkers shall be rinsed with clean water and 

 carefully dried before milking each cow. The practice of moistening the 

 hands with milk is forbidden. 



23. Milking Clothes. Clean overalls, jumper, and cap shall be worn 

 during milking. They shall be washed or sterilized each day and used for 

 no other purpose, and when not in use they shall be kept in a clean place, 

 protected from dust and dirt. 



24. Things to be Avoided by Milkers. While engaged about the dairy or 

 in handling the milk employees shall not use tobacco nor intoxicating liquors. 

 They shall keep their ringers away from their nose and mouth, and no milker 

 shall permit his hands, fingers, lips, or tongue to come in contact with milk 

 intended for sale. 



25. During milking the milkers shall be careful not to touch anything 

 but the clean top of the milking stool, the milk pail, and the cow's teats. 



26. Milkers are forbidden to spit upon the walls or floors of stables, or 

 upon the walls or floors of milk houses, or into the water used for cooling the 

 milk or washing the utensils. 



27. Fore-milk. The first streams from each teat shall be rejected, as this 

 fore-milk contains large numbers of bacteria. Such milk shall be collected 

 into a separate vessel and not milked on to the floors or into the gutters. The 

 milking shall be done rapidly and quietly, and the cows shall be treated kindly. 



28. Milk and Calving Period. Milk from all cows shall be excluded for 

 a period of forty-five days before and seven days after parturition. 



29. Bloody and Stringy Milk. If milk from any cow is bloody and stringy 

 or of unnatural appearance, the milk from that cow shall be rejected and the 

 cow isolated from the herd until the cause of such abnormal appearance has 

 been determined and removed, special attention being given in the meantime 

 to the feeding or to possible injuries. If dirt gets into the pail, the milk shall 

 be discarded and the pail washed before it is used. 



30. Make-up of Herd. No cows except those receiving the same super- 

 vision and care as the certified herd shall be kept in the same barn or brought 

 in contact with them. 



31. Employees Other than Milkers. The requirements for milkers, rela- 

 tive to garments and cleaning of hands, shall apply to all other persons hand- 

 ling the milk, and children unattended by adults shall not be allowed in the 

 dairy nor in the stable during milking. 



32. Straining and Strainers. Promptly after the milk is drawn it shall 

 be removed from the stable to a clean room and then emptied from the milk 

 pail to the can, being strained through strainers made of a double layer of 

 finely meshed cheesecloth or absorbent cotton thoroughly sterilized. Sev- 

 eral strainers shall be provided for each milking in order that they may be 

 frequently changed. 



33. Dairy Building. A dairy building shall be provided which shall be 

 located at a distance from the stable and dwelling prescribed by the local 

 commission, and there shall be no hogpen, privy, or manure pile at a higher 

 level or within 300 feet of it.
