CONTROL SERIES BULLETIN No. 48 JULY, 1929 



Eradication of Puilorum Disease 

 in Massachusetts 



(Bacillary White Diarrhea) 

 1928-1929 



By W. R. Hinshaw, E. F. Sanders, and G. L. Dunlap 



This is the ninth annual progress report on the eradication of puilorum 

 disease in Massachusetts under the Poultry Disease Elimination Law of 

 1919. Eradication rather than control has now become the objective of 

 this service. The basic disease eradication principle is the recognition of 

 and the removal of every infected individual on the premises. 



Annual testing of the entire flock; retesting infected flocks within the 

 season, until a non-reacting report is obtained; an increasing number of 

 poultrymen buying new stock from non-reacting 100 per cent tested flocks; 

 and a continued yearly increase in number of birds tested, with a constant 

 increase in the percentage of poultry population in non-reacting flocks, all 

 point to progress in eradication.
