Federal representative. An individual employed and authorized by the Federal government to perform the tasks required by this subpart.

Federal veterinarian. A veterinarian employed and authorized by the Federal government to perform the tasks required by this subpart.

Hatching eggs. Eggs in which birds or poultry are allowed to develop.

Infected. Affected by the virus or bacterium that causes the specified disease.

Interstate. From one State into or through any other State.

Known to be exposed. Determined by either a Federal veterinarian or a State veterinarian to be at risk of developing Newcastle disease because of association with birds or poultry infected with Newcastle disease, excrement from birds or poultry infected with Newcastle disease, or other material touched by birds or poultry infected with Newcastle disease, or because there is reason to believe that association has occurred with Newcastle disease or vectors of Newcastle disease, as determined by either a Federal veterinarian or a State veterinarian.

Moved. Shipped, transported or otherwise moved, or delivered or received for movement, by any person.

Newcastle disease. Newcastle disease is an acute, rapidly spreading, and usually fatal viral infection of poultry caused by an avian paramyxovirus serotype 1 that meets one of the following criteria for virulence: The virus has an intracerebral pathogenicity index (ICPI) in day-old chicks (Gallus gallus) of 0.7 or greater; or multiple basic amino acids have been demonstrated in the virus (either directly or by deduction) at the C-terminus of the F2 protein and phenylalanine at residue 117, which is the N-terminus of the F1 protein. The term “multiple basic amino acids” refers to at least three arginine or lysine residues between residues 113 and 116. In this definition, amino acid residues are numbered from the N-terminus of the amino acid sequence deduced from the nucleotide sequence of the F0 gene; 113-116 corresponds to residues −4 to −1 from the cleavage site. Failure to demonstrate the characteristic pattern of amino acid residues as described above may require characterization of the isolated virus by an ICPI test. A failure to detect a cleavage site that is consistent with virulent strains does not confirm the absence of a virulent virus.

Official seal. A serially numbered metal or plastic strip, consisting of a self-locking device on one end and a slot on the other end, that forms a loop when the ends are engaged and that cannot be reused if opened, or a serially numbered, self-locking button that can be used for this purpose.
