Table 3. The Incidence of "Breaks" Observed During the 

 Past Twelve Years 



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. An empty pen to each 

 house should be provided to facilitate cleaning and disinfection during the 

 winter months. Disinfectants approved by the United States Department 

 of Agriculture should be used. 



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

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

 readmitted into the flock. 



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

 known pullorum-disease-free flocks. The Massachusetts Department of 

 Agriculture, 41 Tremont Street, Boston, should be consulted regarding addi- 

 tions or replacements in the 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 

 hatching. 



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

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

 skunks that may carry or spread the infection. 



10. Poultrymen should not custom-hatch for untested or infected flocks (in- 

 cluding 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. (Suth bags if properly disinfected will be safe for further use.)
