for breeding purposes, and the birds from such a 

 flock that are killed for food should be inspected 

 by a competent veterinarian, so that none may be 

 used for food purposes that are diseased to such 

 an extent as to render the food unfit for human 

 consumption. 



All birds in a flock infected with tuberculosis 

 that die should be cremated to prevent further 

 spread of the disease from that source. All drop- 

 pings and cleanings from the henhouse and runs 

 should be disinfected with calcium chloride, a five 

 per cent solution of carbolic acid or other reliable 

 disinfectant before spreading on the fields.
