of all of the annual, semiannual, and other official tuberculin tests 

 which are made and keep copies of the same on file and compile 

 them annually for the use of the association. 



55. Disposition of coivs sick with diseases other than tuber- 

 culosis. Cows having rheumatism, leucorrhea, inflammation of 

 the uterus, severe diarrhea, or disease of the udder, or cows that 

 from any other cause may be a menace to the herd shall be re- 

 moved from the herd and placed in a building separate from that 

 which may be used for the isolation of cows with tuberculosis, 

 unless such building has been properly disinfected since it was 

 last used for this purpose. The milk from such cows shall not 

 be used nor shall the cows be restored to the herd until permission 

 has been given by the veterinary inspector after a careful physical 

 examination. 



56. Notification of veterinary inspector. In the event of 

 the occurrence of any of the diseases just described between the 

 visits of the veterinary inspector, or if at any time a number of 

 cows become sick at one time in such a way as to suggest the 

 outbreak of a contagious disease or poisoning, it shall be the duty 

 of the dairyman to withdraw such sickened cattle from the herd, 

 to destroy their milk, and to notify the veterinary inspector by 

 telegraph or telephone immediately. 



57. Emaciated cows. Cows that are emaciated from chronic 

 diseases or from any cause that in the opinion of the veterinary 

 inspector may endanger the quality of the milk, shall be removed 

 from the herd. 



Bacteriological Standards. 



58. Bacterial counts. Certified milk shall contain less than 

 10,000 bacteria per cubic centimeter when delivered. In case a 

 count exceeding 10,000 bacteria per cubic centimeter is found, 

 daily counts shall be made, and if normal counts are not restored 

 within 10 days the certificate shall be suspended. 



59. Bacterial counts shall be made at least once a week. 



60. Collection of samples. The samples to be examined shall 

 be obtained from milk as offered for sale and shall be taken by a 

 representative of the milk commission. The samples shall be 

 received in the original packages, in properly iced containers, and 

 they shall be so kept until examined, so as to limit as far as 

 possible changes in their bacterial content. 



61. For the purpose of ascertaining the temperature, a sep- 

 arate original package shall be used, and the temperature taken 

 at the time of collecting the sample, using for the purpose a 

 standardized thermometer graduated in the centigrade scale. 



62. Interval betiveen milking and plating. The examinations 

 shall be made as soon after collection of the samples as possible, 

 and in no case shall the interval between milking and plating the 

 samples be longer than 40 hours.
