82.2—Criteria for determining birds or poultry to be infected with, exposed to, or free from END.
(a)
The determination that birds or poultry are infected with END must be made by either a Federal veterinarian or a State veterinarian. 1 They will base that determination on one or more of the following factors: clinical evidence (signs, post-mortem lesions, and history of the occurrence of END); diagnostic tests; 2 or epidemiological evidence (evaluation of clinical evidence and the degree of risk posed by the potential spread of END based on population and exposure factors, including evaluation of whether the birds and poultry have had the opportunity to be in contact with birds or poultry infected with END or with excrement from birds or poultry infected with END, or if the birds and poultry have shared feed or water with birds or poultry infected with END).

(b)
The determination that birds or poultry are exposed to END must be made by either a Federal veterinarian or a State veterinarian. They will base that determination on an evaluation of all related circumstances, including: the proximity of the birds or poultry to birds or poultry infected with END, to excrement from birds or poultry infected with END, and to other material touched by birds or poultry infected with END; the number of birds or poultry infected with END to which the birds or poultry were exposed; the species involved; the virulence of the END to which the birds or poultry were exposed; and the length of time the birds or poultry were in contact with birds or poultry infected with END, and to material touched by birds or poultry infected with END. Birds or poultry determined to be exposed to END will continue to be treated as exposed unless they are subsequently determined to be infected with END or until either a Federal veterinarian or a State veterinarian finds them to be free of END based on one or more of the factors listed in paragraph (a) of this section.
