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

 puUorum 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 

 disinfected. 



TESTING OF FOWL OTHER THAN CHICKENS 



During the past year 22,914 samples from fowl other than chickens, including 

 15,989 turkeys, 5,653 pheasants, 844 quail, 285 partridge, 76 ducks, 32 geese, 23 

 pigeons, 7 guinea fowl, and 5 pea fowl, were tested. No reactors were detected. 



NONREACTING FLOCKS CLASSIFIED BY COUNTIES 



This is the first season in the entire testing history that all tested flocks have 

 been classified as nonreacting. A total of 269 nonreacting flocks, representing 

 1,008,750 birds, was identified in 11 counties, as listed in table 4. A total of 260 

 flocks was 100 percent tested, whereas 9 flocks were partially tested. The latter 

 group constituted 11,968 birds in six counties. Partial flock testing is not recom- 

 mended to determine the true status of a flock. It is encouraging that 98.81 percent 

 of all birds tested are in 100 percent nonreacting flocks, and it is hoped that in the 

 near future all flocks will be 100 percent tested. 



It was stated in previous sections that only one flock revealed infection which 

 was eliminated through retesting. The laboratory appreciates the splendid co- 

 operation received from the flock owners in the attempts to eradicate the disease. 

 It is hoped that flock owners will continue to cooperate to the fullest extent in order 

 that the disease may be eradicated from the Massachusetts poultry industry.
