Memorandum to: Network Laboratories and Regional Administrators and Status Assessors for the Chronic Wasting Disease Voluntary Herd Certification Program (CWD VHCP)


Subject: Update to clarify current samples collected, diagnostic test used, reporting, and approved laboratories on the CWD VHCP.


Background Since the CWD VHCP was established in 2002, there have been many developments, including updates to the samples collected, the diagnostic screening test used, and approved laboratories on this program.


This directive provides a summary to all parties of the laboratory changes that should be in place since the release of the original national standards, to ensure that all procedures and reporting reflect the current sampling and testing, and submission to the appropriate laboratory. These changes are reflected in the CWD VHCP Module 13 of the Accredited Veterinarian's Manual.


Effective Date: Immediately


Both the obex and the retropharyngeal lymph nodes (RPLN) must be submitted for all farmed cervids tested for CWD.


The primary target tissue tested for all members of the family Cervidae (with the exception of members of the genus Odocoileus), such as elk, red deer, reindeer, sika deer, and fallow deer, is the obex of the medulla.


The primary target tissue tested for Odocoileus species (including white-tailed deer and mule deer) is the RPLN.


The additional submitted tissues will be frozen and held by the laboratory until the initial test is completed.


The standard screening test for the CWD VHCP is currently the Bio-Rad ELISA, and reporting should reflect this.


Effective immediately, please ensure that the results of analysis for CWD are reported as follows.


Results of Analysis on Samples Submitted for CWD via Bio-Rad ELISA Testing


Tested: CWD not detected


(Where the specimen submitted contained the correct target tissue for the species being tested.)


The sample should be reported as follows: "Bio-Rad ELISA was negative for disease specific PrP (PrPCWD). Based on the tissue available for testing, this animal was unlikely to have died from CWD."


Tested: CWD not detected in secondary target tissue


(Where the specimen submitted did not contain the primary target tissue identified for the species being tested.)


The sample should be reported as follows: "Bio-Rad ELISA was negative for disease specific PrP (PrPCWD). Based on the tissue available for testing, this animal was unlikely to have died from CWD."


This may include the following:


samples from white-tailed and mule deer where the RPLN was not submitted but obex and/or brain is available for testing;


samples from elk where the obex was not submitted but the RPLN or another area of the brain is available for testing


Submitted: Unsuitable for testing


(Where the specimen submitted did not have identifiable brain or RPLN tissue available for testing, and a report for analysis is completed.)


The sample should be reported as "Submitted: Unsuitable for testing." This should be followed with an explanation as to the cause for this result.


This may include the following:


samples where tissues other than brain/obex or RPLN are received;


samples where a skull/head is submitted but no testable tissues are present. Note: For the purposes of testing under the CWD VHCP, all samples being reported as "Tested: CWD not detected" and "Tested:


CWD not detected in secondary target tissue" will be considered as "tested" when the herd is assessed for advancement within the program.


The following are the network laboratories currently approved by CFIA for CWD testing using Bio-Rad ELISA.


Note: The term "Recognized laboratories" has been changed to "CFIA approved laboratories."


Agri-Food Laboratories Branch TSE Laboratory 6909 – 116th Street Edmonton, Alberta T6H 4P2


Animal Health Laboratory Laboratory Services (University of Guelph) Ontario Veterinary College Building 49, Box 3612 Guelph, Ontario N1H 6R8


Manitoba Agriculture, Food and Rural Initiatives Veterinary Services Branch Veterinary Diagnostic Services 545 University Crescent Winnipeg, Manitoba R3T 5S6


Ministère de l'Agriculture des Pêcheries et de l'Alimentation du Québec (MAPAQ) (French only) Laboratoire d'epidemiosurveillance animale du Québec 3220 Sicotte Street Saint-Hyacinthe, Quebec J2S 7X9


Prairie Diagnostic Services Room 2604, Diagnostic Immunology Laboratory 52 Campus Drive Saskatoon, Saskatchewan S7N 5B4


This directive will remain in effect until the CWD VHCP National Standards are updated to reflect these changes, or until it is superseded by another directive. If you or your staff members have any concerns or questions, please contact Dr. Amanda Amaratungaor Dr. Aru Balachandran to discuss.


Sincerely,


Dr. Penny Greenwood National Manager Disease Control and Animal Welfare Terrestrial Animal Health Division
