Preliminary activities

1. Obtain and read chapter 13 Chronic Wasting Disease Herd Certification of the Accredited Veterinarian's Manual, including the National Standards for the Chronic Wasting Disease Herd Certification Programs (CWD HCP).

2. Schedule a meeting with the local Canadian Food Inspection Agency (CFIA) district veterinarian to review the terms and conditions for accreditation, and discuss the duties and procedures that the accredited veterinarian must follow for the delivery of a CWD HCP. This will include a review of the regional CWD HCP requirements.

3. A tutorial or a review of the transmissible spongiform encephalopathy (TSE) brain and lymph node sampling techniques in cervids is suggested at this time. Videos of TSE sampling techniques are available through the Public Health Agency of Canada's training platform. To access the videos:

  1. go to the website
  2. choose desired language
  3. create an account
  4. fill in your profile
  5. you will receive an email to complete your registration
  6. complete the registration using the enrolment key C64A0123
  7. go to

4. Establish a valid accreditation agreement with the CFIA for the delivery of the CWD HCPs. For more information on the Accredited Veterinarian program, see chapter 1 of the Accredited Veterinarian's Manual.

5. Advise the cervid owner/cervid farm operator to contact the regional administrator (RA) to learn the requirements to participate in, advance, and maintain certification in the regional CWD HCP. Contact information for the current regional administrators is found in Appendix A of chapter 13 of the Accredited Veterinarian's Manual.

6. Discuss the requirements of the CWD HCP with the owner/cervid farm operator. Assess the facilities, herd management, and record-keeping practices to gauge the degree to which the producer can be successful, and to identify any changes in record keeping or management that are necessary to meet CWD HCP requirements.

Note: The National Standards detail the minimum requirements of the CWD HCPs. Certain regions in Canada may have a standard that is higher than what is set out in the national standards. Obtain a copy of the regional CWD HCP from the regional administrator noting any differences in requirements over and above what is detailed in this manual. Periodically (at least once a year) speak with the regional administrator to obtain any updates to the regional program.

General responsibilities

7. The accredited veterinarian's role in delivery of a CWD HCP is vital. The accredited veterinarian works closely with the owner/cervid farm operator to ensure that all CWD HCP requirements are met. Responsibilities of the accredited veterinarian include:

See section 1.4, Program Delivery of the National Standards for more information on the roles and responsibilities of accredited veterinarians.

8. The CWD HCPs are carried out in co-operation with cervid owners, cervid farm operators, accredited veterinarians, provincial/territorial governments, industry stakeholder organisations, approved laboratories and the CFIA. The roles assumed by each of these organizations may vary in different provinces of Canada. Roles and responsibilities of each of these partners are listed in the CWD HCP National Standards:

Annual inspections, inventories, and annual report

Annual inspection

9. The accredited veterinarian must visit the enrolled herd at least once a year to conduct the annual inspection. The annual inspection must occur within 3 months of the anniversary date, and includes visual inspection of the premises, observing the general health of the herd, and verifying compliance to all regional CWD HCP requirements. See Section 4.1.2 of the National Standards for more information on the annual inspection.

Inventories

10. An inventory must be conducted every year and must occur within 3 months of the anniversary date.

The third-party inventory is conducted at least every 2 years. The third-party inventory is conducted by the accredited veterinarian or by an approved third party (for example, animal health technician, provincial/territorial staff, CFIA inspector/veterinarian). See Section 1.4, Program Delivery, of the National Standards for more information on approved third parties.

The third-party inventory identifies all cervids on the premises. All cervids 12 months of age or older must be individually inspected and all identification devices must be recorded.

A producer inventory is conducted in the years when a third-party inventory is not required. The producer inventory may identify the cervids by the use of unique identification devices (such as dangle tags) which are visible at a distance. The producer inventory may be conducted by the owner/cervid farm operator.

11. The reconciliation of inventories must be verified by the accredited veterinarian. Reconciliation of the current inventory with the previous year's inventory will account for every cervid 12 months of age or older and include supporting documentation, such as status certificates for introductions of live cervids and embryos, laboratory reports, bills of purchase and sale, and cervid movement permits.

See Section 3.11 of the National Standards for more information on documentation requirements and Section 4.1.1 for more information on inventories.

Annual report

12. The annual report is the responsibility of both the accredited veterinarian and the owner/cervid farm operator. The annual report contains the annual inspection report, the reconciliation of the inventories with supporting documentation, laboratory reports, and documentation related to biosecurity.
See Section 4.1.3 of the National Standards for more information on the annual report.

When the accredited veterinarian is satisfied that the annual report adequately documents all CWD HCP requirements, the report is signed and forwarded to the status assessor. The annual reported must be submitted within 3 months of the anniversary date.

CWD surveillance

13. Testing is the most important CWD HCP pillar. All cervids 12 months of age or greater that die, are humanely euthanized, or are hunted on farm must be tested for CWD. Until January 1, 2020, less than 100% of all cervids 12 months of age or greater that are slaughtered must be tested. See section 4.2.1 of the National Standards for more information on the testing requirements.

Laboratories approved by the CFIA for CWD testing are listed in Appendix D of chapter 13 of the Accredited Veterinarian's Manual.

14. The obex of the medulla and the retropharyngeal lymph node must both be submitted for CWD testing. See Appendix B of chapter 13 of the Accredited Veterinarian's Manual for sampling procedures.

15. The head of the cervid may be submitted directly to a CFIA-approved laboratory by the owner/cervid farm operator or the accredited veterinarian may collect tissue samples for submission to the laboratory. In all cases, heads or tissue samples should be chilled or frozen immediately upon being found. The head of the cervid must bear all identification in situ and all samples must be accompanied by identification.

Note: Required samples removed from the head by anyone other than an accredited veterinarian, appropriate provincial staff, provincial laboratory, or a CFIA veterinarian/inspector will not be considered as submitted.

Sick animals

16. Owners/cervid farm operators are required to report to their accredited veterinarian any illness in a cervid 12 months of age or greater that lasts longer than 2 weeks, except a physical injury. The accredited veterinarian is responsible for monitoring the outcome of the case and reporting the case to the CFIA is CWD is a differential diagnosis.

Note: CWD is a reportable disease. If an animal exhibits signs for which CWD is a differential diagnosis, the local CFIA district office must be contacted.

Limited entry

17. Introductions to the herd of live cervids and embryos can only be from herds at an equivalent or higher CWD HCP status. Appropriate documentation is required for every cervid that is born on or enters the herd.

See Section 4.3, Enrolled Herd of the National Standards for more information regarding the restrictions on introductions to the herd.

Biosecurity

18. The accredited veterinarian will work with the owner/cervid farm operator to develop a biosecurity plan tailored to the operation. The biosecurity plan must address risks posed by inadequate fencing, feed storage, feed sources, water sources, vehicles, taxidermy and carcasses, and previously owned equipment.

See Section 4.4, Biosecurity of the National Standards for more information regarding biosecurity requirements.
