Non-Reacting and Positive Flocks Classified by Counties 



Table 4 gives the distribution of non-reacting and positive flocks by counties. 

 No reactors were found among 295 one hundred percent tested and 22 partially 

 tested flocks. The total number of birds in the 100 percent tested non-reacting 

 flocks was 583,733 and in the partially tested non-reacting group, 16,874. Wor- 

 cester, Essex, Middlesex, Bristol, and Plymouth Counties led, in the order listed, 

 in the number of non-reacting flocks and birds. In Barnstable, Berkshire, Dukes, 

 and Franklin Counties all flocks were 100 percent tested. 



A total of 15 infected flocks which were distributed among eight counties was 

 detected. Three counties had one infected flock each, three counties two each, 

 and two counties three each. Norfolk County had the largest number of birds 

 in infected flocks. Fewer infected flocks and birds in such flocks are listed than 

 were listed in the previous report. 



The results in this table show that non-reacting stock is available in all of the 

 counties listed. Flock owners with infected flock? should make every effort 

 possible to eliminate their infected flocks or birds and replace them with puUorum- 

 free stock. It is hoped that some day the number of infected flocks will be in- 

 significant. This can be accomplished only through systematic, conscientious 

 testing and the adoption of measures designed to eliminate the infection and to 

 prevent the reintroduction of the disease.
