Section 345IAC5-2-21. "Genetically less susceptible exposed sheep", "genetically resistant exposed sheep", "genetically susceptible animal", and "genetically susceptible exposed animal" defined

   (a) "Genetically less susceptible exposed sheep" means the following:

(1) Any exposed AA QR sheep or embryo unless it is epidemiologically linked to a scrapie-positive RR or AA QR sheep.

(2) Any exposed AV QR sheep unless it is epidemiologically linked to a scrapie-positive RR, QR, AV QQ, or VV QQ sheep.

  (b) "Genetically resistant exposed sheep" means any exposed RR sheep or embryo that was not designated exposed because of exposure to, or the presence in a flock of, a scrapie-positive RR sheep.

  (c) "Genetically susceptible animal" means any of the following:

(1) A goat or goat embryo.

(2) A QQ sheep or sheep embryo.

(3) A sheep or embryo of undeterminable genotype.

(4) A genetically susceptible exposed animal.

  (d) "Genetically susceptible exposed animal" means any exposed animal or embryo other than a low-risk exposed animal that is one (1) of the following:

(1) A goat or goat embryo.

(2) A QQ sheep or sheep embryo.

(3) A sheep or embryo of undeterminable genotype.

(4) An AV QR sheep or sheep embryo that is epidemiologically linked to a scrapie-positive RR, QR, AV QQ, or VV QQ sheep, including a AV QR sheep or sheep embryo epidemiologically linked to a positive animal for which the 136 codon type either cannot be determined or is unavailable at the time of depopulation.

(5) An AA QR sheep or sheep embryo that is epidemiologically linked to a scrapie-positive RR or AA QR sheep.

(6) An RR sheep or sheep embryo that is epidemiologically linked to a scrapie-positive RR sheep.
