VSFCP National Standards (Revised June 2017)

National Standards Index

5. Program Specific Pathway 2A—Third Eyelid

Note: This pathway is not available to goats.

5.1

A blood sample is collected from all animals older than 14 months and submitted for genotyping by a CFIA-approved laboratory. Samples (e.g. blood samples) required for genotyping must be taken by a veterinarian accredited to deliver the VSFCP or a third party under the supervision of a veterinarian accredited to deliver the VSFCP (e.g. a veterinary student, a technician).

5.2

All animals 14 months of age or older, that are determined to have the 171QQ (136AA 171QQ, 136AV 171QQ, 136VV 171QQ) genotype, must have a sample of lymphoid tissue collected from the third eyelid by the accredited veterinarian on contract and subjected to testing for scrapie by a laboratory approved by the CFIA for that purpose. A minimum of 50 animals must be biopsied in order to continue in this pathway.

5.3

If all laboratory tests for scrapie are negative, the flock may officially apply to enter the VSFCP and, if accepted, enter at
level B.

5.4

Commencing upon acceptance into the program, brain samples from all sheep/goats over 12 months of age that die on the farm (deadstock) must be submitted for scrapie testing by a CFIA-approved laboratory. If no suitable samples have been submitted for testing for a period of time equal to or exceeding 12 months, at least one animal 18 months of age or older, which has resided in the flock/herd for no less than 18 months, is to be humanely destroyed (in any manner: slaughter, euthanasia) and a sample submitted for testing. If the flock is genotyped, then select a genetically susceptible animal to be humanely destroyed for testing.

Alternatively if no suitable samples have been submitted for testing for a period of time equal to or exceeding 12 months, an enrolled producer may be permitted to remain on the program without advancing to the next level for one additional year (allowing time to raise an animal for slaughter and testing). For certified producers, they would incur a one year status penalty dropping them from certified to Level A.

5.5

Standards 4.6 to 4.12 for the introductions of animals, embryos and semen are applicable to this pathway.

5.6

For application to advance to level A, any breeding sheep that were purchased from other farms prior to entering the VSFCP but were not 14 months or older (and thus did not have the third eyelid test) at the time of the first testing must now be subject to genotyping and third eyelid testing as per steps 5.1 and 5.2 above. The results must be submitted along with the annual report and the request to advance to level A.

5.7

The flock may advance to the certified level as per pathway 1. Once a flock has reached the certified level, it maintains this level provided that the requirements for this level (deadstock surveillance, acquisitions) are met. An annual request, with the accompanying annual report including animal inventory and all supporting documentation, must be submitted to the status assessor.

Program Specific Pathway 2B—RAMALT Biopsy

Note: This pathway is available to sheep and goats. Start at 5.10 if dealing with a goat herd on this pathway.

5.8

A blood sample is collected from all sheep older than 12 months and submitted for genotyping by a CFIA-approved laboratory. Samples (e.g. blood samples) required for genotyping must be taken by a veterinarian accredited to deliver the VSFCP, or a third party under the supervision of a veterinarian accredited to deliver the VSFCP (e.g. a veterinary student, a technician).

5.9

All sheep 12 months of age or older that are determined to have the 171QQ (136AA 171QQ, 136AV 171QQ, 136VV 171QQ) genotype must have a RAMALT biopsy collected by the accredited veterinarian on contract and be subjected to testing for scrapie by a laboratory approved by the CFIA for that purpose. A minimum of 50 sheep must be biopsied in order to continue in this pathway.

5.10

All goats 12 months of age or older must have a RAMALT biopsy taken by the accredited veterinarian on contract and subjected to testing for scrapie by a laboratory approved by the CFIA for that purpose. A minimum of 50 goats must be biopsied in order to continue in this pathway.

5.11

If all laboratory tests for scrapie are negative, the flock/herd may officially apply to enter the VSFCP and, if accepted, enter at level B.

5.12

Upon acceptance into the program, brain samples from all sheep or goats over 12 months of age that die on the farm (deadstock) must be submitted for scrapie testing by a CFIA-approved laboratory. If no suitable samples have been submitted for testing for a period of time equal to or exceeding 12 months, at least one animal 18 months of age or older, which has resided in the flock/herd for no less than 18 months, is to be humanely destroyed (in any manner: slaughter, euthanasia) and a sample submitted for testing. If the flock is genotyped, then select a genetically susceptible animal to be humanely destroyed for testing.

Alternatively if no suitable samples have been submitted for testing for a period of time equal to or exceeding 12 months, an enrolled producer may be permitted to remain on the program without advancing to the next level for one additional year (allowing time to raise an animal for slaughter and testing). For certified producers, they would incur a one year status penalty dropping them from certified to Level A.

5.13

Standards 4.6 to 4.12 for the introductions of animals, embryos and semen are applicable to this pathway.

5.14

To apply to advance to level A, any breeding animals that were purchased from other farms prior to entering the VSFCP, but were not 12 months or older (and thus did not have a rectal biopsy) at the time of the first testing, must be subject to genotyping and rectal biopsy (if sheep), as set out in 5.8 and 5.9, and rectal biopsy (for goats), as set out in 5.10. These results must be submitted, along with the annual report and the request to advance to level A.

5.15

The flock/herd may advance to the certified level as per pathway 1. Once a flock/herd has reached the certified level, it maintains this level provided that the requirements for this level (deadstock surveillance, acquisitions) are met. An annual request, with the accompanying annual report including animal inventory and all supporting documentation, must be submitted to the status assessor.
