Genetically susceptible exposed animal.

Genetically susceptible exposed animal. Excluding low-risk exposed animals, any exposed animal or embryo that is also:
(1) A genetically susceptible animal; or
(2) A sheep or sheep embryo of genotype AV QR that the Administrator has determined is epidemiologically linked to a scrapie-positive RR or QR sheep, to a flock that the Administrator has determined may be affected by valine-associated scrapie (based on an evaluation of the genotypes of the scrapie-positive animals linked to the flock), or to a scrapie type to which AV QR sheep are susceptible; or
(3) A sheep or sheep embryo of genotype AA QR that the Administrator has determined is epidemiologically linked to a scrapie-positive RR or AA QR sheep or to a scrapie type to which AA QR sheep are susceptible; or
(4) A sheep or sheep embryo of genotype RR that the Administrator has determined is epidemiologically linked to a scrapie-positive RR sheep or to a scrapie type to which RR sheep are susceptible.
(5) Note: In this definition, R refers to codon 171 and A refers to codon 136, and Q represents any genotype other than R at codon 171 and V represents any genotype other than A at codon 136.
