Increased Efforts Toward Pulloriiin Disease Kradiealiuii: The testing 

 results of tested (locks and the piillorum diagnoses in the diagnostic laboratories 

 continue to show progress in the reduction and eradication of pullorum disease. 

 Every effort should be made to follow through on every known case of pullorum 

 disease and to institute measures that will prevent the further dissemination of the 

 infection and to hasten its complete elimination. The following recommendations, 

 approved by the Massachusetts Federation of Poultry Associations, may serve as a 

 basis for a general eradication program. 



I. Handling of flocks with acute outbreaks: 



A. Affected chicks should be destroyed or reared for broilers. If early 

 liquidation is not possible, then infection should be eliminated through 

 short interval retesting. 



B. In adult flocks special precautionary measures should be instituted 

 to prevent the disease from spreading within the flock or to other flocks. 



1. Flocks in the acute stage of the disease should not be sold. 



2. Affected pens should be isolated if possible. 



3. Medication should be given under the supervision of competent 

 persons. 



4. After the disease has subsided the flock should either be sold or 

 tested at short intervals. 



C. The use of drugs in an acute outbreak should be exercised only upon 

 recommendation by competent persons. 



II. Handling of infected tested breeding flocks: 



A. Flock owners desiring official recognition are compelled to eradicate 

 the disease from their flocks. 



B. Infected breeding flocks whose owners do not wish to receive official 

 recognition should be subjected to a planned eradication program. 



III. Specific sanitary and control measures: 



A. Upon identification of infection, effective plans should be applied re- 

 garding movement and sale of stock. 



1. Infected semi-mature and mature flocks should be slaughtered 

 when sold. 



2. Reactors should be removed and sold for slaughter as soon as 

 possible. 



3. Immediately upon detection of infection in breeder and commer- 

 cial hatcheries, effective plans should be instituted to prevent the 

 further spread of the disease. 



B. Sanitary conditions consistent with a sound eradication program 

 • should be maintained on all contaminated premises. 



C. Only flocks that meet the qualifications of the pullorum-passed and 

 pullorum-clean grades should be permitted to produce hatching eggs.
