APHTHOUS FEVER 



By C. J. MARSHALL, 8tate Veterinarian. 



In the Fall of 1908 there was an outbreak of the Foot-and-Mouth 

 Disease in Pennsylvania. It originated in Michigan and was carried 

 to various parts of Pennsylvania by cattle shipped from Buffalo. 

 There were eight points of infection received about the same time. 

 The infection extended over an area of one hundred miles in length 

 and in the part of the state where animal husbandry is most ex- 

 tensively practised. The infection was found on one hundred farms. 

 One thousand three hundred and twenty head of cattle, 877 swine, 

 52 sheep and 3 goats were diseased or exposed to the infection. They 

 are appraised at |57,702.49, promptly killed, buried and the premises 

 were disinfected. The cost of disinfection averaged about |100 per 

 herd. All told this outbreak cost a little over |86,000. The Federal 

 Bureau of Animal Industry paid two-thirds of the appraised value 

 of the livestock destroyed and the cost of disinfection. The State 

 paid the balance. It required three months to stamp out the disease 

 at that time. The State was then free from Aphthous Fever for a 

 period of six years. 



The recent outbreak was discovered on two farms in Lancaster 

 county and in one cow in the Union Stockyards at Pittsburg on Oc- 

 tober 24, 1914. The infection has existed in something over 630 

 herds in 27 counties in Pennsylvania since that time. Infection was 

 carried from the stockyards in Chicago through Pittsburg and Lan- 

 caster to various places in Pennsylvania in a period of less than two 

 weeks. Five days previous to October 24th we were notified that 

 the disease had been diagnosed in two counties in southern Michigan 

 and two other counties in northern Indiana. In the meantime our 

 cattle shippers, commission men and over eight hundred veterinarians 

 had been warned that the disease had been found in this country and 

 that all should be on the lookout for symptoms of Aphthous Fever. 

 In many cases infected herds were located and quarantined before 

 suspicious symptoms had been observed. Seven administration dis- 

 tricts had been established in the infected territory with the head 

 office at Harrisburg. Each district was in charge of an experienced 

 agent of the federal and state government. The federal inspectors 

 were appointed agents of the State Livestock Sanitary Board and
