118 ANNUAL REPORT OF THE 0£E. Doc. 



The tenth Order of General Quarantine became efifective May 1, 

 1915. It still held in quarantine portions of Allegheny, Butler, 

 Chester, Erie, Jefferson, Lebanon, Philadelj)hia, Schuylkill, Warren 

 and Westmorland counties. 



During the latter part of April the disease broke out in portions 

 of Philadelphia. In this territory about 30,000 hogs are kept and fed 

 principally on garbage. In one herd a few hogs were observed that 

 showed suspicious symptoms of foot-and-mouth disease. There were 

 about three hundred hogs, one cow and two calves on this premise. 

 The cow and two calves showed no symptoms of the disease. A good 

 sized vesicle on the nose of one of the hogs was ruptured and the con- 

 tents rubbed into the mouths of the three bovine animals. They 

 never developed the disease and according to the owner's statement 

 had not been sick or showed any suspicious symptoms, yet he re- 

 ported that his hogs had been showing somewhat similar symptoms 

 for the past month. From the fact that the cattle showed no lesions 

 of the disease and developed no symptoms from the test applied to 

 them, there was some doubt whether the disease might be due to other 

 causes. About the same time a similar condition of affairs was 

 observed in two adjoining herds of hogs. In order to make sure 

 of the diagnosis, it was decided to place test animals on one of these 

 places. A cow and a yearling bull from the State Farm, where the 

 disease had not existed, were taken to these premises. Material was 

 obtained from an unbroken vesicle on the nose of one of the pigs 

 and injected intravenously into each of the bovine animals. In about 

 forty-eight hours both animals showed well marked lesions of foot- 

 and-mouth disease. Their temperatures were high, they were slob- 

 bering, smacking the lips, vesicles in the mouth and well marked 

 foot lesions. All diseased animals in this section were then promptly 

 destroyed and those in the infected herds which showed no symptoms 

 of disease were sent to a slaughter house. 3,153 hogs were killed 

 on account of this outbreak. A careful observation was kept over 

 the balance of the hogs in this territory and no more trouble de- 

 veloped. It is remarkable under tlie conditions that more of these 

 hogs did not develope foot-and-mouth disease. 



The source of infection in this outbreak was not positively traced. 

 It might have come from garbages but is more likely to have been 

 brought there by hog dealers and the owners themselves as some of 

 them were known to have been at the various slaughter houses dur- 

 ing the time animals from quarantined areas were being slaughtered. 

 A general quarantine was placed on all territory south of Washington 

 Avenue and between the Delaware and Schuylkill rivers. 



The eleventh Order of General Quarantine became effective June 1, 

 1915. This placed an embargo against all shipments from the State 

 of Kentucky. It was done for the reason that the disease was found 

 in two shipments of hogs that arrived in Philadelphia from Kentucky 

 the latter part of May. It released all territory in the State except 

 portions of Allegheny, Erie, Philadelphia, Schuylkill and Warren 

 counties. 



At this time the officers of the County Fairs desired information 

 in reference to holding their fall exhibition. The following instruc- 

 tions were sent to the Secretary of each County Organization : 



"The State Livestock Sanitary Board has decided to allow the exhibition of 

 cloven footed animals at Agricultural Fairs in territory that is not under State 

 Quarantine for foot and mouth disease. No cloven footed animals will be permitted
