218 MANUAL OF MILK PRODUCTS 



54. The proper designated officers of the American Association of 

 Medical Milk Commissions should receive copies of reports 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 cows sick with diseases other than tuberculosis. — 

 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 removed 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 occur- 

 rence 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 in- 

 spector 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 ex- 

 ceeding 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 repre- 

 sentative 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 separate 

 original package shall be used, and the temperature taken at the time 

 of collecting the sample, using for the purpose a standardized ther- 

 mometer graduated in the centigrade scale.
