DISEASES OF SWINE 477 



Regulation 48. Swine which are not diseased with hog cholera 

 or swine plague and which have not been exposed to the infection 

 thereof may be shipped from one State or Territory or the District 

 of Columbia without restriction by the regulations of the Secretary 

 of Agriculture, and subject only to such restrictions as may be im- 

 posed on the shipment by State or Territorial or District of Columbia 

 officers at destination. 



Regulation 49. Public stock yards shall be considered in- 

 fected and no swine shall be shipped therefrom for feeding or stock- 

 ing purposes. No diseased swine shall be shipped from the stock 

 yards, but shall be slaughtered, subject to condemnation on post- 

 mortem inspection ; and all swine in a certain lot or shipment shall 

 be considered diseased when one or more of them show evidence 

 of the disease. Swine that are not diseased and have been merely 

 exposed by being in the yards may be shipped to a recognized 

 slaughtering center for immediate slaughter. Where, however, a 

 part of the yard is set apart for the reception of uninfected ship- 

 ments of swine and is kept free of infection, swine may be shipped 

 from such part without restriction. Should such part be contam- 

 inated by the introduction of diseased swine, said animals shall be 

 immediately removed therefrom, and the chutes, alleys, and pens 

 occupied by them thoroughly cleaned and disinfected as herein- 

 after provided; 



Regulation 50. Cars and other vehicles and pens or yards 

 which have contained diseased or exposed swine shall be cleaned 

 and disinfected as soon as possible after unloading. Cars shall 

 not be removed before the inspector has had time to ascertain the 

 condition of the animals and give notice that the cars must be 

 cleaned and disinfected. Cleaning and disinfection shall be done 

 by first removing all litter and manure and then saturating the 

 interior surfaces of the cars and the woodwork, flooring, and ground 

 of the chutes, alleys, and pens with a 5 per cent solution of 100 

 per cent carbolic acid in water, with sufficient lime to show where 

 it has been applied. (Ind. B. 113.) 



TUBERCULOSIS. 



Cause of Increasing Heavy Losses. Tuberculosis in the hu- 

 man family has been lessening materially during the past fifteen 

 years, but reports from the various meat-packing centers of the 

 country fail to show the same encouraging condition regarding 

 tuberculosis in hogs during the same space of time. It must be 

 admitted that reports have come from several localities during 

 the past four years showing a decrease in the number of tuberculosis 

 swine sent to market, but a review of the collected records of the 

 country at large shows an increase rather than a decrease in the num- 

 ber of swine affected. Indeed, there is probably no disease of hogs, 

 not even excepting hog cholera, which is causing heavier losses to the 

 hog raiser than tuberculosis, and it is also the cause of great loss to 

 the packers and of much anxiety to the veterinary inspector of meats. 

 Until recent years tuberculosis had been looked upon as of uncom- 

 mon occurence, and only of importance from a meat-inspection
