Chronic wasting disease is a transmissible spongiform
encephalopathy (TSE) affecting cervids, which is wide-
spread in North America but which has never been
reported to date in the Community.

On 3 June 2004, the European Food Safety Authority
(EFSA) published an opinion recommending that a
targeted surveillance should be undertaken of cervids in
the Community. The aim of such surveillance would be
to detect
the possible presence of TSEs in cervids.
Accordingly, provision should be made for Member
States to carry out surveys in line with that opinion.

Regulation (EC) No 999/2001 lays down rules for the
prevention, control and eradication of TSEs in animals.
That Regulation, as amended by Regulation (EC) No
1923/2006 lays
for monitoring
programmes for TSEs in cervids. Accordingly, it is now
possible to provide for surveys for TSEs in cervids to be
carried out by Member States in this Decision.

Those surveys should include wild and farmed deer
species. Since wild deer should primarily be sampled
during the hunting season which is of limited duration,
in order
time to
to allow Member States sufficient
achieve target numbers of samples, this Decision should
therefore apply following the adoption of Regulation (EC)
No 1923/2006 amending Regulation (EC) No 999/2001.

ANNEX II

Minimum requirements for a survey to detect the presence of chronic wasting disease in cervids

1. Sampling by target Member States of target species

(a) The target Member States, shall take samples for testing for chronic wasting disease (CWD) in accordance with
Table 1 for their wild red deer and white-tailed deer population and table 2 for their farmed red deer population.

Those samples may be taken from all target groups in the target Member States.

(b) The competent authority of the target Member States shall take into consideration the following criteria when

deciding upon the sample selection sampling for target species:

(i) all cervids must be over 18 months of age; the age shall be estimated on the basis of dentition, obvious signs

of maturity, or any other reliable information;

(ii) in the case of healthy shot cervids, samples must be taken in particular from male cervids;

(iii) in the case of healthy slaughtered cervids, samples must be taken in particular from older male and female

cervids.

(c) The competent authority of the target Member States shall take into consideration exposure to the following

potential risk factors, where present, when deciding upon the sample selection for target species:

(i) densely populated deer areas;

(ii) high scrapie incidence;

(iii) high BSE incidence;

(iv) cervids which have consumed potentially TSE-contaminated feeding stuffs;

(v) cervids on farms or in regions where imports from regions affected by CWD of cervids or their products have

been recorded in the past.

(d) The competent authority of the target Member States shall use random sampling to select target species for

sampling.

2. Sampling for CWD in all cervid species by all Member States

All Member States shall take samples for CWD from clinical/sick cervids and fallen/culled cervids, as a priority, as well
as from road-injured or killed cervids of all cervid species. The competent authority of the Member States shall
endeavour to maximise awareness of these cervids and to ensure that as many such cervids are tested for CWD as
possible.

3. Sampling and laboratory testing

A sample of obex shall be collected and tested for each cervid in the samples referred to in points 1 and 2 of this
Annex. At least a portion of each sample shall be kept fresh or frozen until a negative result is obtained, in case
bioassay is required.

The competent authority of the Member States must refer to point 3 of Chapter C of Annex X to Regulation EC
(No) 999/2001 for guidance on methods and protocols.

Rapid tests as referred to in point 4 of Chapter C of Annex X to Regulation EC (No) 999/2001 used for transmissible
spongiform encephalopathy (TSE) detection in obex of bovine or small ruminant animals shall be considered suitable
for use in the sampling referred to in points 1 and 2 of this Annex. Member States may also use immunohisto-
chemistry for screening purposes for which purpose they shall satisfy a proficiency test by the Community Reference
Laboratory. Where a Member State is unable to confirm a positive rapid test result, they shall send adequate tissue to
the CRL for confirmation. In the case of positive findings of TSE, the protocol as provided for in point 3.2, (c)(i) and
(ii), Chapter C of Annex X to Regulation EC (No) 999/2001 shall apply.

4. Genotyping

The prion protein genotype shall be determined for each positive finding of TSE in cervids in accordance with the
guidelines of the Community Reference Laboratory for TSEs.

ANNEX III

Measures following testing of cervids

1. Where a cervid intended to be placed on the market for human consumption has been selected for testing for CWD,
the Member States shall ensure the traceability of that carcase and ensure that it is not released for commercial sale
until a negative result to the rapid test has been obtained.

2.

Insofar as possible, and whenever point 1 applies, the hunter, gamekeeper or farmer, where known, shall be informed
when samples are submitted for testing for CWD and the results of a positive rapid test communicated as soon as
possible by authorised means.

3. The Member States shall reserve the right to retain material for further diagnostic or research purposes until a negative

result to the rapid test for CWD has been obtained.

4.

Insofar as possible, except for the material to be retained for further diagnostic or research purposes, all parts of the
body of a cervid found positive to the rapid test, including the hide, shall be directly disposed of in accordance with
Articles 4(2)(a), (b) or (e) of Regulation (EC) No 1774/2002 (1).
