During the 1957-58 testing season, a total of 324 chicken, turkey, and 

 pheasant flocks was tested. Among 1,040,027 samples tested, 0.0009 per- 

 cent was positive, which is a definite decrease over the percentage (0.01) 

 positive in the previous season. Only one infected breeding flock was 

 detected which constituted a "break." At the close of the season all flocks 

 were classified as negative. This is the first season in the testing history 

 that 100 percent of all birds tested are in nonreacting flocks.
