TUBERCULIN TEST ORDINANCES. 75 



' ' Identification of dairy cattle. That all cows on dairy farms produc- 

 ing milk for the District of Columbia be tagged, tattooed, or otherwise 

 marked for purposes of identification. 



' ' Tuberculin testing or pasteurization required. That all milk pro- 

 duced for use in the District of Columbia shall either come from cattle- 

 free from tuberculosis as shown by the tuberculin test, which tuberculin 

 test shall be repeated at least once every year, or be subjected to pas- 

 teurization under the supervision of the health department in case the 

 herd is not tuberculin tested. 



' ' New dairy cattle to be tuberculin tested. That hereafter no addition 

 .shall be made to any herd producing milk for use in the District of Col- 

 umbia, whether such herd has or has not been tuberculin tested, unless 

 the cattle so added have been tested with tuberculin and found to be free 

 from tuberculosis. 



" Neiu licentiates to have herds tuberculin tested. That hereafter no 

 license shall be granted to produce milk for use in the District of Col- 

 umbia unless the herd by which such milk is to be produced has been 

 found by the tuberculin test to be free from tuberculosis." 



The compulsory pasteurization of all the milk supply of a 

 city will be attended with difficulties, but these are slight as 

 compared with those associated with the enforcement of a 

 tuberculin test ordinance. Chicago has adopted the scheme 

 of enforcing the tuberculin test, with the alternative of pas- 

 teurizing the milk. 



Test by city official. The testing of cattle is best carried on 

 by a veterinarian employed by the municipality. It is highly 

 desirable that he be paid well enough to warrant devoting his 

 time exclusively to the work in hand. The requirements of 

 the work, even in a small city, call for the undivided attention 

 of one man for milk inspection and tuberculin testing. vThere 

 should be a decided increase in the budget allotments of munic- 

 ipalities for the proper enforcement of tuberculin test ordi- 

 nances, f The important requirement is that the inspector 

 should noYbe engaged in private practice and consequently 

 dependent upon the good will of the dairymen. The customary 

 system of paying a moderate salary for a portion of the time- 

 of a practicing veterinarian is detrimental to efficient work for 

 the municipality. If the application of the tuberculin test is 

 made optional with the veterinarian, the test will certainly not 

 be made. The veterinarian can not do his full duty without
