| Detailed Reports |
- When the first case of CWD was diagnosed in an elk on a game farm in
Canada in early 1996 (in an animal imported from the USA in 1989), the
herd was put into isolation. Other disease control measures included
tracing other animals which had been part of the same shipment from
the USA and incineration of the carcass of the affected elk. (W27.01May96.cwd1)
- Four herds in Saskatchewan were quarantined following detection of
CWD in one animal from each herd. (W27.03Sept00.CWD1)
- A herd of elk in Nebraska, in which CWD was detected, was
quarantined and monitored for additional cases of CWD for three years.
After that time, no more cases having been detected, the quarantine
was lifted. (N8.18.w9)
- Infected farmed populations are quarantined. (J40.66.w1)
- Quarantine is one control option for captive cervids (the other
being depopulation). (P10.67.w1)
- It has been suggested in the proposed USDA program for management of
CWD in farmed deer and elk that a certification status could be
provided for producers who maintain their herds for a minimum of five
years with no evidence CWD. (D110.w3)
- Proposed herd management plan from the USDA would include provisions
for depopulation or quarantine. (D110.w3)
- In the Multi-state Plan (in preparation), which is being developed
by a number of states including Colorado, Wyoming, Nebraska and South
Dakota, it is recommended that live free-ranging deer and elk from
areas in which CWD is known to occur should not be translocated
from those areas (except for research purposes) and further that
caution should be employed when considering translocation of live
free-ranging deer and elk from areas in which CWD is not known to
occur. (D109)
- No transplantation of live deer or elk out of the CWD zone in
Wyoming will be allowed except for research purposes. (D114.w3)
- It has been recommended by the Wyoming Game and Fish Department that
complete carcasses not be transported out of the CWD-endemic
zone and that the only parts of the carcass which should be
removed from the zone are "cut and wrapped meat, boned meat,
animal quarters or other portions with no part of the spinal column or
head attached, hides without the head, cleaned (no meat or other
tissue attached) skull plates with antlers attached, antlers with no
meat or other tissue attached." (D114.w3)
- The head (brain, eyes, tonsils, various lymph nodes), spinal cord, spleen and various lymph nodes in the body are most likely to
contain infectivity (J40.66.w1,
D118,
W402.24Mar03.CWD1)
and transport of these, particularly from
CWD-endemic areas, should be avoided. (D118)
- Parts of the carcass which it is generally considered may be
transported with minimal risk of transporting CWD infectivity include:
cut and wrapped meat, boneless meat, hides (without the head attached),
upper canine teeth, antlers (if skull plates are to remain attached to the antlers
these should be cleaned and disinfected before transportation) and
finished taxidermy heads. (D114.III.w3,
W402.24Mar03.CWD1,
W411.26Mar03.CWD3,
W425.27Mar03.CWD5)
Other TSE Diseases
Scrapie:
- Introduction of scrapie into a scrapie-free country, region or flock
could be prevented by prohibition of all movements of sheep and goats
and their products into the area or flock, except from a country known
to be scrapie-free. Some countries may allow entry of live animals but
an extended post-entry quarantine period, of five to seven years, may
be imposed, or the progeny only may be released from quarantine, again
after a prolonged time. (J64.11.w4)
