3. Every reactor, regardless of its value, should be removed from the premises 

 for slaughter immediately upon receipt of the report. 



4. Offal from all birds dressed for market or home consumption as well as 

 dead birds that are not fit for consumption should be burned. 



5. The poultry houses, runs, and equipment, should be thoroughly cleaned 

 and disinfected immediately after removal of reactors. Provide an empty pen 

 to each house to facilitate cleaning and disinfection during the winter months. 

 Use disinfectants approved by the United States Department of Agriculture. 



6. Birds removed from the premises to egg-laying contests, exhibitions, etc., 

 should be held in quarantine and determined free of disease before they are re- 

 admitted into the flock. 



7. Purchase of stock in the form of adults, chicks, and eggs should be from 

 known pullorum-disease-free flocks. Consult your county agent regarding 

 additions or replacements in your flock. 



8. Eggs should not be saved for hatching until after a flock has been tested 

 and all the infected birds removed. Early pullet testing will permit early hatch- 

 ing. 



9. Fresh and infertile eggs from unknown or infected sources should not be 

 fed to chickens or exposed to animals such as crows, sparrows, and skunks that 

 may carry or spread the infection. 



10. Poultrymen should not custom hatch for untested or injected flocks 

 (including fowl other than chickens). 



11. Owners of pullorum-disease-free flocks should not have hatching done 

 where infected eggs or stock may be found. 



12. Poultrymen should not buy feed in bags that have been used or exposed 

 to infection. (Such bags if properly disinfected will be safe for further use.) 



13. Poultrymen should regard fowl other than chickens as a possible source of 

 puUorum infection unless tested and found free from puUorum disease. 



14. Poultrymen should not use equipment that has been exposed to or con- 

 taminated with infective material unless it is properly cleaned and sterilized or 

 disinfected. 



Testing of Fowl Other Than Chickens 



A total of 17,249 samples collected from fowl other than chickens was tested 

 during the past year. Turkey samples numbered 17,224, among which were 

 1.56 percent reactors. The infection was confined to three out of the 59 flocks. 

 These three flocks were retested and further reactors were detected. The per- 

 centage of reactors detected among the retests was 1.68. One large infected flock 

 was retested, which accounts for a higher percentage of reactors among the re- 

 tests than among the total tests. 



The response of infected turkey flocks to retesting is different from that usually 

 observed ampng chickens. Many doubtful reactions are encountered in in- 

 fected turkey flocks which appear infrequently or not at all in non-infected flocks. 

 However, puUorum infection in turkey breeding flocks can be controlled and 

 eliminated through retesting, although more retests may be required than in the 

 case of chickens. 



Turkey breeders should recognize the necessity of exercising every precaution 

 in establishing and maintaining puUorum-free flocks. Some owners resort to the 

 whole blood test for determining the puUorum status of a flock. Laboratory and 

 field evidence to date has shown that the whole blood test is not reliable in the 

 testing of turkeys for puUorum disease.
