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

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

 mitted 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 additions 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 permit hatching 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 

 pullorum infection unless tested and found free from pullorum 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 dis- 

 infected.
