286 THE MILK SITUATION IN THE DISTBICT OF COLUMBIA. 



RULES REGULATING THE TUBERCULIN TESTING OF Cows. 



Rule 1. Who may make the test. Tuberculin tests made on animals supply- 

 ing the city of Chicago with milk or milk products may be made by licensed 

 graduate veterinarians, Federal or State veterinarians, Federal, State, or city 

 dairy and milk inspectors, and by persons regularly employed by the Chicago 

 department of health for that purpose. 



Rule 2. The test to be employed. The regular injection method of tuberculin 

 testing shall be employed. The temperature shall be taken at least four times 

 on the day preceding the inoculation and at least six times on the day following 

 the inoculation, at not less that two-hour intervals. A rise of 2 over the aver- 

 age temperature on the day preceding the inoculation shall be considered a posi- 

 tive test. If a rise of from 11 to 2 is obtained, the results shall be considered 

 doubtful and the animal subjected to a later retest. Animals that have been 

 added to the herds within the last six weeks shall be tested by the ordinary 

 injection test supplemented by Calmette's ophthalmic test, and a positive result 

 with either one or the other shy 11 condemn the animal. The department of 

 health shall have the power to require the retesting of all animals submitted for 

 milk supply by the Calmette ophthalmic method or any other method to be de- 

 cided on in the future. 



Rule 3. The numbering and tagging of animals. All tested animals shall bear 

 an indestructible tag indicating the series, and also the number assigned to the 

 animal. Tags placed by Federal, State, and municipal inspectors will designate 

 by abbreviations or otherwise the series represented. Veterinarians supplying 

 the numbered tags must have their initials or some other distinctive mark ap- 

 pear on the tag with the number to indicate the series. 



Rule 4. Statement to be submitted. A statement must be filed with the divi- 

 sion of milk inspection for every tuberculin-tested animal supplying the city of 

 Chicago with milk or milk products. This statement must indicate the number 

 and series given to the animal, which number and series must correspond with 

 the tag or mark worn by the animal. This statement must also state the age 

 and color of the animal and any other distinctive marks shown by the animal. 

 In addition the statement mustfShow the temperature record of the animal on 

 the days preceding and following the test, the date and the exact time of taking 

 these temperatures, and the date and time of making the injection and amount 

 and kind of tuberculin used ; the name of the owner and the signature of the 

 person making the test, together with the official capacity of said person or per- 

 sons making the test and their address. The statement submitted shall also 

 indicate the date of the last tuberculin test made upon the animal and the method 

 of making this test, and the length of time that the animal has been in the herd.
