. Sask. farm | Wildlife official says disease must be taken seriously
Saskatchewan’s first chronic wasting disease case of the year has been
confirmed.
The Canadian Food Inspection Agency reported on its website that an elk
farm was confirmed as infected Feb. 3.
This brings the total number of domestic deer and elk herds in Canada to 71
since CWD was first documented in 1996.
A high of 21 cases was recorded in 2001, but most years since have averaged
three confirmations per year.
Terry Bolinger, regional director of the Canadian Wildlife Health
Co-operative in Saskatoon, warned against not taking the disease seriously just
because the number of cases is low.
“This problem is not going to go away. It’s well established in wildlife
populations so it is going to continue to be introduced into game ranches due to
contact with wildlife reservoirs,” said Bolinger.
“It indicates (the one case) that it’s smoldering along as a disease that
crosses into game ranches.… As it spreads more widely in the province, if they
don’t enhance their biosecurity around game ranches, I think those numbers will
start to increase again.”
CWD is a reportable disease under the Health of Animals Regulations, and
all suspected cases must be reported to the CFIA. Testing is mandatory in
Manitoba, Saskatchewan, Alberta and the Yukon. Reporting is voluntary in the
rest of Canada.
Bolinger said there’s evidence that the prevalence of CWD is increasing in
areas where it is established. There’s also confirmation that it’s spreading
further in Saskatchewan and Alberta.
There are also potential concerns beyond wild cervids.
“It’s transmissible to caribou, reindeer and they’ve detected it in moose
in other locations,” he said.
Bolinger said proposed strategies include reducing contact with wild
populations of deer and elk, but further research is needed on how to deal with
the disease in the wild.
One possible bright spot is research by the Vaccine Infectious Disease
Organization (VIDO-InterVac) in Saskatoon.
“There are some potential developments that might be useful in managing the
disease in game ranches and in the wild, but we don’t have any concrete
solutions at this stage.”

Domestic cervid herds confirmed to be infected with CWD in Canada in 2014
Date confirmed Location Animal type infected February 3 Saskatchewan Elk
Chapter 5 - Export to the U.S. 5.7 Cervids
Between 1996 and 2002, chronic wasting disease was diagnosed in 39 herds of
farmed elk in Saskatchewan in a single epidemic. All of these herds were
depopulated as part of the Canadian Food Inspection Agency’s (CFIA) disease
eradication program. Animals, primarily over 12 mo of age, were tested for the
presence CWD prions following euthanasia. Twenty-one of the herds were linked
through movements of live animals with latent CWD from a single infected source
herd in Saskatchewan, 17 through movements of animals from 7 of the secondarily
infected herds.
***The source herd is believed to have become infected via importation of
animals from a game farm in South Dakota where CWD was subsequently diagnosed
(7,4). A wide range in herd prevalence of CWD at the time of herd depopulation
of these herds was observed. Within-herd transmission was observed on some
farms, while the disease remained confined to the introduced animals on other
farms.
The CFIA’s eradication policy was developed in year 2000, based on the best
available information at that time. The working assumptions were the following:
CWD affects elk, mule deer, and white-tailed deer; the maximum incubation period
in cervids is 36 mo; clinical cases are infectious for up to 18 mo before death;
spread occurs primarily via direct contact; CWD prions are highly resistant to
degradation; and the environment can be a source of infection (15). The
classical disease control principles employed by the CFIA in the eradication
effort included the following: quarantine and depopulation of CWD-infected
herds; testing of euthanized animals > 12 mo of age; tracing of all contacts
to the infected herd; euthanasia and testing of animals in contact with infected
animals within 36 mo of CWD diagnosis; and surveillance of those in contact with
infected animals between 36 and 60 mo (4). These assumptions and policies appear
to have successfully controlled the spread of CWD in farmed elk in Canada
(4).

Chronic Wasting Disease (CWD) outbreaks and surveillance program in the
Republic of Korea Chronic Wasting Disease (CWD) outbreaks and surveillance
program in the Republic of Korea

Chronic wasting disease (CWD) has been recognized as an important prion
disease in native North America deer and Rocky mountain elks. The disease is a
unique member of the transmissible spongiform encephalopathies (TSEs), which
naturally affects only a few species. CWD had been limited to USA and Canada
until 2000. On 28 December 2000, information from the Canadian government showed
that a total of 95 elk had been exported from farms with CWD to Korea. These
consisted of 23 elk in 1994 originating from the so-called “source farm” in
Canada, and 72 elk in 1997, which had been held in pre export quarantine at the
“source farm”.Based on export information of CWD suspected elk from Canada to
Korea, CWD surveillance program was initiated by the Ministry of Agriculture and
Forestry (MAF) in 2001. All elks imported in 1997 were traced back, however elks
imported in 1994 were impossible to identify. CWD control measures included
stamping out of all animals in the affected farm, and thorough cleaning and
disinfection of the premises. In addition, nationwide clinical surveillance of
Korean native cervids, and improved measures to ensure reporting of CWD suspect
cases were implemented. Total of 9 elks were found to be affected. CWD was
designated as a notifiable disease under the Act for Prevention of Livestock
Epidemics in 2002. Additional CWD cases - 12 elks and 2 elks - were diagnosed in
2004 and 2005. Since February of 2005, when slaughtered elks were found to be
positive, all slaughtered cervid for human consumption at abattoirs were
designated as target of the CWD surveillance program. Currently, CWD laboratory
testing is only conducted by National Reference Laboratory on CWD, which is the
Foreign Animal Disease Division (FADD) of National Veterinary Research and
Quarantine Service (NVRQS). In July 2010, one out of 3 elks from Farm 1 which
were slaughtered for the human consumption was confirmed as positive.
Consequently, all cervid – 54 elks, 41 Sika deer and 5 Albino deer – were culled
and one elk was found to be positive. Epidemiological investigations were
conducted by Veterinary Epidemiology Division (VED) of NVRQS in collaboration
with provincial veterinary services. Epidemiologically related farms were found
as 3 farms and all cervid at these farms were culled and subjected to CWD
diagnosis. Three elks and 5 crossbreeds (Red deer and Sika deer) were confirmed
as positive at farm 2. All cervids at Farm 3 and Farm 4 – 15 elks and 47 elks –
were culled and confirmed as negative. Further epidemiological investigations
showed that these CWD outbreaks were linked to the importation of elks from
Canada in 1994 based on circumstantial evidences. In December 2010, one elk was
confirmed as positive at Farm 5. Consequently, all cervid – 3 elks, 11
Manchurian Sika deer and 20 Sika deer – were culled and one Manchurian Sika deer
and seven Sika deer were found to be positive. This is the first report of CWD
in these sub-species of deer. Epidemiological investigations found that the
owner of the Farm 2 in CWD outbreaks in July 2010 had co-owned the Farm 5. In
addition, it was newly revealed that one positive elk was introduced from Farm 6
of Jinju-si Gyeongsang Namdo. All cervid – 19 elks, 15 crossbreed (species
unknown) and 64 Sika deer – of Farm 6 were culled, but all confirmed as
negative. : Corresponding author: Dr. Hyun-Joo Sohn (+82-31-467-1867, E-mail:

snip...
5. On July 16, 2012, DNR received a notice from the Texas Veterinary
Medical Diagnostic Lab ("Texas Vet Lab”) that a sample from an adult male deer
killed at Pine Ridge tested presumptively positive for CWD. (DNR has an
agreement with the Texas Vet Lab to run these preliminary tests.) Because the
Texas Vet Lab found this presumptive positive result, protocols required the
sample to be sent to the National Veterinary Services Laboratory ("National
Lab”) in Ames, Iowa for final confirmation. On July 18, 2012, the National Lab
confirmed the positive CWD result in the deer.
6. On July 19, 2012, DNR notified the Brakkes of the positive test by
phone. Mr. Brakke was out of state.
snip...
12. The Brakkes depopulated the Hunting Preserve, as specified in the
Agreement, from September 10, 2012 to January 31, 2013. As part of this effort,
the Brakkes, the staff and their customers killed 199 captive deer and nine
captive elk. The DNR obtained 170 CWD samples. (Samples were not taken from
fawns and one adult female who was killed in a manner that made sampling
impossible.) Of these 199 deer, two additional adult male deer tested positive
for CWD. Information provided by the Brakkes confirmed that these two additional
deer originated from the Brakke Breeding Facility.
13. DNR installed, with the Brakke's permission, an interior electric fence
on October 1 and 2, 2012.
14. The Brakkes cleaned and disinfected, under DNR supervision, the feeders
and ground surrounding the feeders on April 5, 2013.
15. On April 26, 2013, the Brakkes hand-delivered a notice to the DNR’s
Chief of Law Enforcement Bureau, notifying the DNR that they would no longer
operate a hunting preserve on the Quarantined Premises. The Brakkes did not
reveal any plans to remove the fence around the Quarantined Premises or to
remove the gates to and from the Quarantined Premises in this April 26, 2013
letter.
16. On June 3, 2013, DNR became aware that sections of the exterior fence
surrounding the Quarantined Premises had been removed and that some, if not all,
of the exterior gates to and from the Quarantined Premises were open.
17. On June 4, 2013, DNR received reports from the public in the area that
four wild deer were observed inside the Quarantined Premises.
18. On June 5, 2013, DNR conducted a fence inspection, after gaining
approval from surrounding landowners, and confirmed that the fenced had been cut
or removed in at least four separate locations; that the fence had degraded and
was failing to maintain the enclosure around the Quarantined Premises in at
least one area; that at least three gates had been opened; and that deer tracks
were visible in and around one of the open areas in the sand on both sides of
the fence, evidencing movement of deer into the Quarantined Premises.

Wisconsin : 436 Deer Have Escaped From Farms to Wild
Date: March 18, 2003 Source: Milwaukee Journal Sentinel
Contacts: LEE BERGQUIST lbergquist@journalsentinel.com
State finds violations, lax record keeping at many sites, report says A
state inspection of private deer farms, prompted by the discovery of chronic
wasting disease, found that 436 white-tailed deer escaped into the wild,
officials said Tuesday
The Department of Natural Resources found that captive deer have escaped
from one-third of the state's 550 deer farms over the lifetime of the
operations. The agency also uncovered hundreds of violations and has sought a
total of 60 citations or charges against deer farm operators.
Hundreds of deer escape
The DNR found a total of 671 deer that escaped farms - 436 of which were
never found - because of storm-damaged fences, gates being left open or the
animals jumping over or through fences.
In one example in Kewaunee County, a deer farmer's fence was knocked down
in a summer storm. Ten deer escaped, and the farmer told the DNR he had no
intention of trying to reclaim them. The DNR found five of the deer, killed them
and cited the farmer for violation of a regulation related to fencing.
Another deer farmer near Mishicot, in Manitowoc County, released all nine
of his whitetails last summer after he believed the discovery of chronic wasting
disease was going to drive down the market for captive deer.
The DNR found 24 instances of unlicensed deer farms and issued 19
citations.
Game Farms Inspected
A summary of the findings of the Department of Natural Resources'
inspection of 550 private white-tailed deer farms in the state: The deer farms
contained at least 16,070 deer, but the DNR believes there are more deer in
captivity than that because large deer farms are unable to accurately count
their deer. 671 deer had escaped from game farms, including 436 that were never
found.
24 farmers were unlicensed. One had been operating illegally since 1999
after he was denied a license because his deer fence did not meet minimum
specifications.
Records maintained by operators ranged from "meticulous documentation to
relying on memory." At least 227 farms conducted various portions of their deer
farm business with cash. Over the last three years, 1,222 deer died on farms for
various reasons. Disease testing was not performed nor required on the majority
of deer. Farmers reported doing business with people in 22 other states and one
Canadian province. ..

Elk escape from captive cervid facility in Pennsylvania near West Virginia
border
SOUTH CHARLESTON, W.Va. – The West Virginia Division of Natural Resources
(WVDNR) has confirmed with officials from the Pennsylvania Department of
Agriculture (PDA) that at least two elk, including one adult bull and one cow,
have escaped from a captive cervid facility (deer and elk farms) in Greene
County, Pa. Greene County shares a common border with Marshall, Wetzel and
Monongalia counties in West Virginia. The elk escaped from a captive cervid
facility located approximately three miles from the West Virginia-Pennsylvania
border.
The PDA regulates captive cervid facilities in Pennsylvania. A
representative of the agency was unaware if the recent escaped elk were tagged.
The WVDNR regulates captive cervid facilities in West Virginia. In West
Virginia, all captive cervids in breeding facilities must be ear-tagged, and
there are currently no reported elk escapes from any facility in West Virginia.
A bull elk has been seen recently in Wetzel County, W.Va., according to
WVDNR officials. There have been no reports of cow elk sightings in either
Wetzel County, W.Va., or Greene County, Pa. No free-ranging wild elk live within
150 miles of Wetzel County. The elk sighted in Wetzel County is likely the
escaped animal from the captive facility in Pennsylvania.

Game Farm, CWD Concerns Rise at Boone and Crockett Club
Friday, March 28, 2014 Concerned about captive deer operations transmitting
diseases to wild herds, the Boone and Crockett Club now officially supports
state bans on commercial import and export of deer or elk.
The Club also opposes efforts to relax regulation of captive cervid
breeding operations or to remove management authority over such operations from
state wildlife agencies.
A full position statement, posted here, was passed at the Club’s December
meeting.
The Club’s concerns were reinforced at the recent Whitetail Summit hosted
by the Quality Deer Management Association (QDMA), the first summit to focus on
key issues and challenges facing free-ranging white-tailed deer.
“Of all the presentations, seminars and findings, I was most pleased to see
the attention given to the connections between chronic wasting disease (CWD) and
the game farming industry. This has been on our radar, and on the radar of QDMA,
other conservation groups, state agencies and sportsmen for quite some time,”
said Richard Hale, chairman of the Club’s Records Committee.
Hale added, “Congratulations to QDMA on one of the most impressive and
well-run summits I’ve had the pleasure of attending and for keeping this issue
front and center.”
CWD is a degenerative brain disease that affects elk, mule deer,
white-tailed deer, and moose. The disease can be transmitted by direct
animal-to-animal contact through saliva, feces and urine, and indirectly through
environmental contamination. CWD is fatal in deer, elk and moose, but there is
no evidence that CWD can be transmitted to humans, according to the CDC and The
World Health Organization.
Documented cases of CWD have been found in captive and/or wild deer and elk
in 22 states and two Canadian provinces. In some, but not all, cases where the
disease has been found in wild populations, the disease is present in captive
populations within these regions.
In 2002, the Boone and Crockett Club, Rocky Mountain Elk Foundation and the
Mule Deer Foundation formed the CWD Alliance. Its purpose was to pool resources,
share information and collaborate on ways to positively address the CWD issue.
Other organizations have since joined the Alliance, including QDMA and the
Wildlife Management Institute, which now administers the Alliance website
www.cwd-info.org.
“Evidence strongly suggests that captive animals infected with CWD can
serve as the source for the spread of the disease to other captive animals, and
between captive animals and wild populations,” said Hale. “To reduce the risk to
wild deer populations, several states passed laws prohibiting game farming or
live captive deer and elk importation, but now they are fighting efforts to
expand captive deer and elk breeding and shooting operations within their
jurisdictions. The captive cervid industry is persistent in proposing new
legislations to overturn these laws, or transfer the authority of captive deer
and elk from state fish and game agencies to their respective departments of
agriculture.”
No vaccine or treatment is available for animals infected with CWD and once
established in a population, culling or complete depopulation to eradicate CWD
has provided only marginal results. In fact, the prevalence of CWD is rising at
an alarming rate in some infected wild deer populations. Prevention is the only
truly effective technique for managing diseases in free-ranging wildlife
populations. Consequently, what can be done is minimizing the spread of CWD by
restricting intra- and interstate transportation captive, privately owned
wildlife, which frequently occurs in game farming.
boone and crockett club position statement
REGULATION OF GAME FARMS First Adopted December 7, 2013 - Updated December
7, 2013
Situational Overview
The captive cervid industry, also referred to as game farming, uses
artificial means to breed captive deer, elk, and other cervids for sale in
shooting preserve operations. These game farms commonly transport captive deer
and elk to other shooting preserves in a state or in other states.
Transportation of captive, game farm animals has been shown to increase the
risk of spreading parasites and infectious, diseases, such as chronic wasting
disease (CWD) and bovine tuberculosis, to other captive and wild cervids in new
locations. There is currently no way of testing live animals for CWD, and
infected animals show no signs for at least 16-18 months post-infection. There
is no vaccine, and despite fenced enclosures, captive animals often come in
contact with wild populations thereby spreading diseases. Once CWD is present,
the area cannot be decontaminated even if infected animals are removed. As a
result, many states have banned or are attempting to ban the importation of
captive cervids (as well as intact carcasses of hunter-killed, wild cervids) to
lower the risk of spreading CWD and other infectious diseases.
Position
The Boone and Crockett Club supports state bans on importing or exporting
captive deer and elk by game farming operations in order to protect the health
of native populations. The Club opposes any legislation aimed at relaxing
regulations governing captive cervid breeding operations or removing management
authority over such operations from state wildlife agencies. The Club does not
oppose the transportation of wild cervids by state agencies and non-governmental
organizations for the purpose of re-establishing wild game animals to their
historic, open ranges.
The breeding of captive deer, elk, and other cervids for profit to create
abnormally large “trophy” animals for fenced shoots under non-fair chase
conditions are addressed in the Boone and Crockett Club’s positions on “Genetic
Manipulation of Game” and “Canned Shoots.”

DEFRA U.K. What is the risk of Chronic Wasting Disease CWD being introduced
into Great Britain? A Qualitative Risk Assessment October 2012
snip...
In the USA, under the Food and Drug Administration’s BSE Feed Regulation
(21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin)
from deer and elk is prohibited for use in feed for ruminant animals. With
regards to feed for non-ruminant animals, under FDA law, CWD positive deer may
not be used for any animal feed or feed ingredients. For elk and deer considered
at high risk for CWD, the FDA recommends that these animals do not enter the
animal feed system. However, this recommendation is guidance and not a
requirement by law.
Animals considered at high risk for CWD include:
1) animals from areas declared to be endemic for CWD and/or to be CWD
eradication zones and
2) deer and elk that at some time during the 60-month period prior to
slaughter were in a captive herd that contained a CWD-positive animal.
Therefore, in the USA, materials from cervids other than CWD positive
animals may be used in animal feed and feed ingredients for non-ruminants.
The amount of animal PAP that is of deer and/or elk origin imported from
the USA to GB can not be determined, however, as it is not specified in TRACES.
It may constitute a small percentage of the 8412 kilos of non-fish origin
processed animal proteins that were imported from US into GB in 2011.
Overall, therefore, it is considered there is a __greater than negligible
risk___ that (nonruminant) animal feed and pet food containing deer and/or elk
protein is imported into GB.
There is uncertainty associated with this estimate given the lack of data
on the amount of deer and/or elk protein possibly being imported in these
products.
snip...
36% in 2007 (Almberg et al., 2011). In such areas, population declines of
deer of up to 30 to 50% have been observed (Almberg et al., 2011). In areas of
Colorado, the prevalence can be as high as 30% (EFSA, 2011).
The clinical signs of CWD in affected adults are weight loss and
behavioural changes that can span weeks or months (Williams, 2005). In addition,
signs might include excessive salivation, behavioural alterations including a
fixed stare and changes in interaction with other animals in the herd, and an
altered stance (Williams, 2005). These signs are indistinguishable from cervids
experimentally infected with bovine spongiform encephalopathy (BSE).
Given this, if CWD was to be introduced into countries with BSE such as GB,
for example, infected deer populations would need to be tested to differentiate
if they were infected with CWD or BSE to minimise the risk of BSE entering the
human food-chain via affected venison.
snip...
The rate of transmission of CWD has been reported to be as high as 30% and
can approach 100% among captive animals in endemic areas (Safar et al., 2008).
snip...
In summary, in endemic areas, there is a medium probability that the soil
and surrounding environment is contaminated with CWD prions and in a
bioavailable form. In rural areas where CWD has not been reported and deer are
present, there is a greater than negligible risk the soil is contaminated with
CWD prion.
snip...
In summary, given the volume of tourists, hunters and servicemen moving
between GB and North America, the probability of at least one person travelling
to/from a CWD affected area and, in doing so, contaminating their clothing,
footwear and/or equipment prior to arriving in GB is greater than negligible.
For deer hunters, specifically, the risk is likely to be greater given the
increased contact with deer and their environment. However, there is significant
uncertainty associated with these estimates.
snip...
Therefore, it is considered that farmed and park deer may have a higher
probability of exposure to CWD transferred to the environment than wild deer
given the restricted habitat range and higher frequency of contact with tourists
and returning GB residents.

11. 12 cases of CWD reported now from S. Dakota, at least 2 different
herds, seemingly 3-4 game farms, from 1 and 4.
Inactivation of the TSE Prion disease
Chronic Wasting Disease CWD, and other TSE prion disease, these TSE prions
know no borders.
these TSE prions know no age restrictions.
The TSE prion disease survives ashing to 600 degrees celsius, that’s around
1112 degrees farenheit.
you cannot cook the TSE prion disease out of meat.
you can take the ash and mix it with saline and inject that ash into a
mouse, and the mouse will go down with TSE.
Prion Infected Meat-and-Bone Meal Is Still Infectious after Biodiesel
Production as well.
the TSE prion agent also survives Simulated Wastewater Treatment Processes.
IN fact, you should also know that the TSE Prion agent will survive in the
environment for years, if not decades.
you can bury it and it will not go away.
The TSE agent is capable of infected your water table i.e. Detection of
protease-resistant cervid prion protein in water from a CWD-endemic area.
it’s not your ordinary pathogen you can just cook it out and be done with.
that’s what’s so worrisome about Iatrogenic mode of transmission, a simple
autoclave will not kill this TSE prion agent.

*** Chronic Wasting Disease Agents in Nonhuman Primates ***
*** our results raise the possibility that CJD cases classified as VV1 may
include cases caused by iatrogenic transmission of sCJD-MM1 prions or food-borne
infection by type 1 prions from animals, e.g., chronic wasting disease prions in
cervid. In fact, two CJD-VV1 patients who hunted deer or consumed venison have
been reported (40, 41). The results of the present study emphasize the need for
traceback studies and careful re-examination of the biochemical properties of
sCJD-VV1 prions. ***
