1. Pastures or paddocks. Pastures or paddocks to which the 

 cows have access shall be free from marshes or stagnant pools, crossed 

 by no stream which might become dangerously contaminated, at suffi- 

 cient distances from offensive conditions to suffer no bad effects from 

 them, and shall be free from plants which affect the milk deleteriously. 



2. Surroundings of buildings. The surroundings of all buildings 

 shall be kept clean and free from accumulations of dirt, rubbish, de- 

 cayed vegetable or animal matter or animal waste, and the stable 

 yard shall be well drained. 



3. Location of buildings. Buildings in which certified milk is 

 produced and handled shall be so located as to insure proper shelter 

 and good drainage, and at sufficient distance from other buildings, 

 dusty roads, cultivated and dusty fields, and all other possible sources 

 of contamination; provided in the case of unavoidable proximity 

 to dusty roads or fields, the exposed side shall be screened with cheese- 

 cloth. 



4. Construction of stables. The stables shall be constructed so as 

 to facilitate the prompt and easy removal of waste products. The 

 floors and platforms shall be made of cement or other nonabsorbent 

 material and the gutters of cement only. The floors shall be properly 

 graded and drained, and the manure gutters shall be from 6 to 8 inches 

 deep and so placed in relation to the platform that all manure will 

 drop into them.
