Regulations Issued to Protect NYS Deer Population from Chronic Wasting
Disease
Emergency Measures Restrict Importation of Certain Deer Species Disease
Could Devastate NY’s Deer Population and Result in Severe Economic Repercussions
on the State’s Sportsman Industry
The New York State Department of Agriculture and Markets and the Department
of Environmental Conservation today announced emergency regulations to prohibit
the importation of Chronic Wasting Disease (CWD) susceptible deer into the
State. The protection of the state’s deer population is important not only to
the balance of the ecosystem but also is critical to supporting the hundreds of
thousands of sportsmen and women whose recreational activities contribute some
$780 million in economic impact statewide.
“These emergency measures will help mitigate the risk of CWD taking a firm
hold here in New York State,” said State Acting Agriculture Commissioner James
B. Bays. “I’m a hunter and an avid outdoorsman, and keeping New York’s wild and
captive deer herds healthy will help protect multi-million dollar industries
that create jobs and provide recreational opportunities for hundreds of
thousands of New Yorkers. From our agency’s perspective, the most important
thing that we can do is limit the exposure of deer to CWD. That’s exactly what
these regulations will do.”
DEC Commissioner Joe Martens said, "New York State has a long tradition of
deer hunting and deer management. It is imperative that we remain vigilant and
prevent Chronic Wasting Disease from entering the State. These regulations will
bolster existing protections already in place in New York and help to maintain a
vibrant population of our most sought after game species. This show of
stewardship help will ensure that sportsmen and sportswomen continue to have
great deer hunting opportunities throughout the state."
The emergency regulations provide a ban on imports of specific species
between November 16, 2013 and August 1, 2018. These species include Rocky
Mountain elk, red deer, mule deer, black-tailed deer, white-tailed deer, sika
deer, and moose.
Currently 21 states including New York prohibit the importation of certain
species of live deer.
CWD is a fatal, neurologic disease to species of deer caused by a disease
agent called a prion, which eventually destroys the brain tissue of infected
animals. Prions are shed by infected animals in their saliva, feces and urine.
The time from infection to the first outward signs of illness (animals appear
weak and unsteady) may be two years or longer. Soil contaminated with CWD prions
cannot be decontaminated and can remain as a source of CWD exposure to wild deer
for years. At the present time, the only accepted means of diagnosis must be
performed after an animal suspected of being infected with CWD is dead.
The primary tool for preventing spread of CWD is the USDA Herd
Certification program, which requires herds that wish to ship animals interstate
to undergo a five year certification process involving surveillance testing and
maintenance of herd inventories. While the program has helped slow the spread of
CWD, it cannot guarantee that certified herds will remain CWD-free. Despite the
best efforts of qualified animal health professionals, CWD has arisen in four
new states (PA, MO, MN, IA) since 2010 and all were participating in the Herd
Certification program. The source of the most recent detection of CWD in both
captive and wild deer in Pennsylvania remains unknown twelve months after the
initial detection. Farms in other states purchased animals from the original
infected herd in Pennsylvania; some escaped and some remain unaccounted for.
Absent these regulations, states with potentially infected deer populations
would be allowed to export deer to New York.
“If we continue to allow imports, we could receive CWD exposed deer or elk
that originated in one state and subsequently passed through a facility in a
third state,” said State Veterinarian, Dr. David Smith. “That’s not a risk we’re
willing to take here in New York. CWD is extremely difficult to detect and
control and once present, the costs to the wild deer population, captive deer
owners, and the entire state are high. We do not want this disease proliferating
throughout our state’s valuable wild populations and captive deer herds. New
York will continue to work with stakeholders and animal health professionals as
these important regulations move forward.”
The costs of states to deal with outbreaks in CWD in terms of resources and
tax dollars are tremendous. Prevalence rates in some parts of Wisconsin are over
20 percent just 10 years after the introduction of CWD into the state, costing
the Wisconsin Department of Natural Resources $14 million the first year alone,
with much of the money pulled from other wildlife programs.
Furthermore, the economic impact that CWD could have on New York State is
considerable. Based on the most recent data, New York’s wild deer herds have a
$780.5 million economic impact in the state, while the economic impact of
captive deer is $13.2 million. There are an estimated 823,000 hunting licenses
in New York and the state ranks third in the nation in residential hunters. In
2011, New York was fourth in the nation in spending by hunters and generated an
estimated $290 million in state and local taxes.
According to the latest data, there are 433 facilities across New York
State that currently hold captive deer. Of these facilities, 25 imported a total
of 400 CWD-susceptible deer from January 1, 2011 through March 29, 2013.
New York will still permit the importation of deer semen for artificial
insemination. Zoos accredited by the Association of Zoos and Aquariums will also
be allowed to still import CWD-susceptible species.
Bruce L. Akey, MS DVM, executive director, Animal Health Diagnostic Center,
College of Veterinary Medicine, Cornell University, said: "The Cornell
University College of Veterinary Medicine Animal Health Diagnostic Center (AHDC)
includes internationally recognized experts on the transmission of disease and
the ecology of diseases in wildlife populations. Chronic Wasting Disease is a
serious threat to New York's wild white-tailed deer herd. With recent
confirmation of CWD in Pennsylvania, our disease specialists are very concerned
that CWD may once again be detected in New York. It is entirely appropriate that
New York's regulatory agencies, the Department of Agriculture and Markets and
the Department of Environmental Conservation, take all reasonable measures to
keep CWD out of New York. Given that there is no test currently available to
detect CWD in live animals prior to movement, strong prevention measures are the
only reasonable and economical way of managing CWD. Once CWD is confirmed in a
population of white-tailed deer, the ecological and economic consequences will
be catastrophic. We applaud the recent regulation prohibiting the importation of
live captive white-tailed deer, the highest known risk factor for CWD."
Chuck Parker, president, New York State Conservation Council, said: “The
New York State Conservation Council takes pride in being a major voice for the
Sportsmen in New York for over 80 years. All of our positions and policies are
the majority consensus of our membership. The voting representatives of the
NYSCC through the affiliations of their local clubs represent upwards of 330,000
sportsmen in this state. The whitetail deer population in New York is enjoyed by
sportsmen and outdoor enthusiast alike. The tradition of hunting has a proud
history in New York and still offers an excellent opportunity for the sportsmen
today. Along with the opportunity to hunt deer comes the economic impact to the
state of nearly $800 million from deer hunting. Chronic Wasting Disease, if it
was to be found in our wild deer population would create a serious
environmental, recreational, and economic impact in New York. The New York State
Conservation Council is strongly committed to supporting actions both by the
Department of Agriculture and Markets and the Department of Environmental
Conservation to ensure that Chronic Wasting Disease never again is found in New
York.”
Jason Kemper, chairman of the Conservation Fund Advisory Board, said: “The
New York State Conservation Fund Advisory Board makes recommendations to state
agencies on state government plans, policies, and programs affecting fish and
wildlife. The wild white-tail deer population is extremely valuable to the State
of New York, generating about $780 million annually by hunting and associated
businesses. License sales associated with deer hunting fund a majority of the
Department of Environmental Conservation’s fish and wildlife management
programs. The health and integrity of New York’s wild deer herd is vital to both
our natural and hunting heritage as well as our economy. We applaud actions
taken by the Department of Agriculture and Markets and the Department of
Environmental Conservation to implement all reasonable measures to prevent CWD
from ever again occurring in New York.”
Mike Fishman, president of the New York Chapter of The Wildlife Society,
said: "The New York Chapter of The Wildlife Society strongly supports the joint
regulatory efforts of the New York State Department of Environmental
Conservation and the New York State Department of Agriculture and Markets to
restrict the import of live, captive deer and other cervids to New York to
prevent the reintroduction of Chronic Wasting Disease (CWD). CWD poses a
significant threat to our wild deer populations. Reintroduction of the disease
could have disastrous consequences on an important ecological and economic
resource in New York. This restriction is a necessary conservation measure to
protect a very important wildlife resource."
Alan White, executive director of the Catskill Center, said: “The Catskill
Center supports efforts by both the Department of Agriculture and Markets, and
the Department of Environmental Conservation to reduce the chances that CWD
would ever again be found in New York State. We support the newly proposed
regulation to prohibit the importation of live captive white-tailed deer from
out of state. These captive deer are a known risk factor for the spread of CWD.
Deer hunting has deep and rich traditions in the Catskill Mountains, and it is
vital that we ensure that the health of New York’s wild white-tailed deer herd
is not compromised by CWD.” A public hearing is scheduled to discuss the
emergency regulations at noon on December 19, 2013 at the New York State
Department of Agriculture and Markets, 10B Airline Drive, Albany.

DEC Seeks Hunter Support to Keep Chronic Wasting Disease Out of New
York
The New York State Department of Environmental Conservation (DEC) reminds
hunters that Chronic Wasting Disease (CWD) continues to pose a potential threat
to New York's wild white-tailed deer herd, and hunters should take precautions
to prevent the spread of the disease. Late last year, CWD was found on a deer
farm in Pennsylvania and in early 2013, CWD was confirmed in Pennsylvania's wild
white-tailed deer herd.
"Preventing the introduction of Chronic Wasting Disease into New York is
vital to protecting our deer herds and is a high priority for DEC," said DEC
Commissioner Joe Martens. "DEC's deer management and outreach efforts work to
ensure the health of New York's deer herd and to protect the recreational and
viewing opportunities deer provide. The most effective way to protect New York's
deer herd is to keep CWD infectious material out of the state and hunters can
play an important role in this effort."
CWD is a highly contagious and deadly brain and nervous system disease that
affects deer, elk, moose and other members of the deer family. CWD is always
fatal and there are no vaccines or treatment available. The agent that causes
the disease is called a prion and it is virtually indestructible. Prions are
found in the lymph nodes, brain and spinal tissues of infected animals, which
can shed (spread) prions in their urine, saliva, and feces. Also, certain parts
of dead animals remain infectious on the landscape and in the soil for many
years. There is no evidence that CWD can infect humans, but DEC urges caution
when handling or processing CWD susceptible animals.
Individuals who hunt deer, elk or moose outside of New York should be
familiar with New York's CWD regulation (6 NYCRR Part 189) regarding the
importation of cervid carcasses and meat back into New York before returning
home. It is illegal to bring in whole carcasses from any CWD susceptible animal
taken at a shooting preserve or to bring in whole carcasses from any state or
province that has had CWD confirmed in wild or captive cervid herds. It is also
illegal to ship the unprocessed trophy head from those preserves or CWD positive
states or provinces. It is legal to import finished mounted heads, however. A
person may only bring back the meat, hide and antlers, and certain parts must be
removed before entering New York. A full list of prohibited parts can be found
on DEC's website.
Before leaving to hunt out-of-state:
•Know the CWD status of the state or province you plan to hunt in since it
can change at any time. For example, four additional states became CWD positive
in 2012 (Iowa, Michigan, Missouri, and Pennsylvania). •If caught in possession
of an illegal carcass with the prohibited parts in New York, the carcass will be
confiscated and destroyed (including antlers, hide and meat). •Know if the state
or province you hunt in requires CWD samples to be submitted after harvest and
before you return home. •Plan accordingly for how to handle an animal if your
hunt is successful. •Locate meat processors in the state or province where you
are hunting ahead of time so you can get your carcass processed quickly and
legally before returning to New York. •If you decide to process your own
animals, de-boning or quartering deer, elk or moose is easy if you plan ahead
and have proper equipment. You can find "how to" videos on the internet before
you go hunting. •If you intend to have a trophy mounted, you will need to know
how to prepare the hide, cape and antlers to eliminate potentially infectious
CWD material. •Proper handling of wild meat and the trophy will eliminate all
the prohibited parts required by New York's CWD regulation.
DEC recommends that hunters dispose of any cervid carcass waste, even from
New York deer, into a proper waste stream either by putting butcher scrap in
with household trash or otherwise ensuring it ends up in a licensed landfill.
Landowners may dispose of their own deer on their property, but it is illegal in
all cases for deer cutters (meat processors/butchers) and taxidermists to
dispose of waste generated from their business in any way other than a landfill
or rendering facility.
DEC also recommends that people not use real deer urine-based lures because
CWD can be transmitted through infected deer urine. Deer urine, used in
commercial lures or scents, originates from captive deer on deer farms. In many
cases, the urine from multiple deer farms is combined for commercial use. If
there are CWD prions in the urine-based product it can contaminate the soil and
potentially spread CWD to deer in that hunting area. If healthy animals ingest
enough infectious CWD material, it could result in the establishment or spread
of the disease. There are proven synthetic deer lure alternatives available on
the market.
Every year hunters in New York are found in possession of deer or other
cervid carcasses taken out-of-state. Many of these were imported illegally.
Bringing in animals from CWD positive states or provinces and discarding the
scrap on the landscape increases the risk that CWD will become re-established in
New York.
This disease threatens the deer herd for every hunter and could jeopardize
the quality of the hunting experience forever. In some states where the disease
is well established, deer herds are experiencing infection rates as high as 50
percent in older age bucks and nearly 30 percent in the overall herd. New York
is fortunate that CWD was not verified in any additional deer since the initial
discovery in Oneida County in 2005. DEC remains vigilant about keeping CWD out
of the state and continues to monitor the latest science about the disease to
help keep New York's herds healthy.

DEC Adopts Chronic Wasting Disease Regulations in Response to Pennsylvania
Discovery
The New York State Department of Environmental Conservation (DEC) has
adopted changes to its Chronic Wasting Disease (CWD) regulations that prohibit
people from importing into New York state certain parts of white-tailed deer or
elk taken in the state of Pennsylvania, DEC Commissioner Joe Martens announced
today. This revision finalizes the emergency rule implemented last
October.
The first case of CWD in the state of Pennsylvania was confirmed by the
Pennsylvania Department of Agriculture last fall. In response, DEC implemented
an emergency rule to protect New York's valuable wild white-tail deer population
by prohibiting the importation of the following parts of hunter-killed deer or
elk taken in Pennsylvania: brain, eyes, spinal cord, tonsils, intestinal tract,
spleen or retropharyngeal lymph nodes.
"As is the case with many other states where CWD has been identified,
hunters who take a deer or elk in Pennsylvania must remove the prohibited parts
before entering New York state," DEC Commissioner Martens said. "Most successful
hunters will opt to butcher a deer or elk and put the meat in a cooler before
traveling back to New York."
DEC has conducted an extensive surveillance program since CWD was first
confirmed in New York in 2005 and has not discovered any additional cases of CWD
since then. CWD is a contagious neurological disease affecting deer, elk and
moose. It causes a characteristic spongy degeneration of the brains of infected
animals resulting in emaciation, abnormal behavior, loss of bodily functions and
death.
It is not known exactly how CWD is transmitted. The infectious agent may be
passed from animal to animal through feces, urine or saliva. The minimal
incubation period between infection and development of the clinical disease
appears to be about 16 months. The maximum incubation period is unknown, as is
the point at which shedding of the CWD agent begins during the prolonged course
of infection.
The movement of infectious material may be one route of transmission. This
amendment to the CWD regulations will prohibit the importation of those parts of
a deer or elk where the disease is most likely to be found. While the exact
health risks of consuming meat from an animal infected with CWD are unknown, DEC
advises hunters not to consume the meat of any animal that acts abnormal and to
exercise precautions when butchering animals, such as using rubber or latex
gloves.
Additional information about CWD and New York's CWD Regulation can be found
on DEC's website.
PART 189: CHRONIC WASTING DISEASE
Status of CWD
No new Chronic Wasting Disease (CWD) cases have been identified in New York
since 2005.
CWD Timeline in New York
Below are details on the initiation of DEC's CWD surveillance program,
information on the first case of CWD in New York and actions taken by DEC to
minimize its spread.
2002
•New York initiated a statewide CWD surveillance program in response to the
first detection of the disease in western states of North America.
2003
•DEC initiated Part 189: Chronic Wasting Disease regulations to reduce the
risk of bringing the disease into New York and to minimize its spread if it was
detected in our state.
2005
•In early April, the first case of CWD was confirmed in five white-tailed
deer from two captive breeding facilities in Oneida County. •After detection, a
containment area was imposed around the infected area in Madison and Oneida
counties (Wildlife Management Unit 6P), with a mandatory deer check for
harvested deer. •An intensive monitoring program was established by DEC to
sample deer in the infected area. Monitoring efforts for the month of April
resulted in testing 290 deer samples from Oneida County, 2 from Madison County
and 25 from Hamilton County. •In late April, two wild white-tailed deer were
confirmed to have CWD within the infected area.
2009
•Mandatory testing of deer from the Oneida/Madison county containment area
ended, with routine testing to continue statewide.
2010
•More than 31,000 wild white-tailed deer were tested statewide from 2002
through 2010. •In July, the Oneida/Madison containment area was lifted as no new
cases of CWD were detected

Positive Case of CWD Found in Oneida County Deer
Mandatory Testing Protocols Find CWD in a Captive White-Tailed Doe
-------------------------------------------------
The 1st positive case of chronic wasting disease (CWD) in New York State
has been confirmed in a white-tailed doe from a captive herd in Oneida County.
CWD is a transmissible disease that affects the brain and central nervous system
of deer and elk. There is no evidence that CWD is linked to disease in humans or
domestic livestock other than deer and elk.
The animal that tested positive for CWD was a 6-year-old white-tailed doe
that was slaughtered from a captive herd in Oneida County as part of the State's
mandatory CWD surveillance and testing protocols. Preliminary tests performed at
the New York State Veterinary Diagnostic Laboratory at Cornell University
determined the presumptive positive, which was confirmed late yesterday by the
National Veterinary Services Laboratory in Ames, Iowa. The New York State
Department of Agriculture and Markets has officially quarantined the index herd
in which the positive deer was found, and will depopulate and test all deer on
the premises. Other herds associated with the index herd have also been
quarantined and an investigation has been initiated to find and test any
susceptible deer that came into contact with the index herd and to assess the
health and environmental risks associated with such establishments. The
Department of Environmental Conservation (DEC) will conduct intensive monitoring
of the wild deer population surrounding the index herd to ensure CWD has not
spread to wild deer.
CWD is a transmissible spongiform encephalopathy (TSE) of deer and elk.
Scientific and epidemiological research into CWD is ongoing. To date, research
shows that the disease is typified by chronic weight loss, is always fatal, and
is transmissible between susceptible species. CWD has only been found in members
of the deer family in North America, which include white-tailed deer, mule deer,
elk and moose.
CWD has been detected in both wild and captive deer and elk populations in
isolated regions of North America. To date, CWD has been found in Colorado,
Illinois, Kansas, Minnesota, Montana, Nebraska, New Mexico, Oklahoma, South
Dakota, Utah, Wisconsin and Wyoming in the United States, and in Saskatchewan
and Alberta in Canada.
Establishing the known CWD health status of captive and wild cervid
populations is a critical component for controlling CWD. In New York, the
responsibility for controlling CWD is shared between the State Department of
Agriculture and Markets, DEC, and the U.S. Department of Agriculture's (USDA)
Animal and Plant Health Inspection Service (APHIS).
New York's cooperative, active surveillance program serves as a model for
the nation in CWD control. The State Department of Agriculture and Markets
monitors the health and movement of all captive deer and elk for the presence of
common livestock diseases, including CWD. In July 2004, the Department initiated
the CWD Enhanced Surveillance and Monitoring Program, which requires captive
deer and elk herd owners to take various actions, including routine sampling and
testing, animal identification and an annual herd inventory. Since the inception
of testing for CWD in 2000, 681 captive deer and elk have been tested and found
negative for CWD. DEC issues licenses to individuals who possess, import or sell
white-tailed deer. DEC also routinely tests New York's wild deer population.
Following the discovery of CWD in Wisconsin, DEC implemented a statewide
surveillance program in April 2002 to test wild white-tailed deer for the
presence of CWD. Samples are collected and sent to an approved USDA laboratory
for analysis. To date, DEC has taken samples from 3457 wild white-tailed deer,
including 40 from the county where the positive deer was found. All samples from
wild white-tailed deer have tested to date have been negative for CWD. DEC will
also implement precautionary regulations limiting transportation and possession
of whole carcasses and some parts of wild deer taken near the location of the
captive herd. These regulations will be similar to those currently in place for
importation of carcasses and parts of deer into New York.
DEC has also implemented regulations restricting various activities to help
control CWD within the State, including restrictions on the importation of live
deer and elk, deer feeding, importation and possession of certain deer parts and
carcasses, and transportation of deer and elk carcasses through New York
State.
USDA APHIS supports individual State programs by providing funding for CWD
prevention and surveillance. USDA APHIS reimburses states conducting CWD testing
on their wild and captive cervid population and also provides indemnification
dollars for captive herds that must be destroyed due to the presence of
CWD.
New York State has 433 establishments raising 9600 deer and elk in
captivity. In the wild, DEC estimates there are approximately one million deer
statewide.

[This is the 1st time CWD has been found in New York State. This is a blow
to the NY cervid industry. Undoubtedly, in addition to the actions identified in
the press release, NY will be examining how the positive deer came to be in New
York State. Was the animal imported from a previously positive region? Was this
a case of spontaneous disease? The officials will be conducting a very thorough
investigation. - Mod.TG]

The New York State Department of Environmental Conservation today
announced that it has received the remainder of test results for chronic wasting
disease (CWD) that were part of intensive sampling efforts in central New York.
DEC has received 2 positive results for the disease out of 292 wild deer
sampled.
The 1st positive result in a wild deer was announced on 27 Apr 2005, and
came from a yearling white-tailed deer sampled from the Town of Verona, Oneida
County. The 2nd positive result is from a 3-year-old doe (female), located
within a mile of the location where the initial positive result was detected.
The sample tissues were tested at the State's Veterinary Diagnostic Laboratory
at Cornell University. These are the 1st known occurrences of CWD in wild deer
in New York State. DEC implemented intensive monitoring efforts after CWD was
found in 2 captive white-tailed deer herds in Oneida County, the 1st incidents
of CWD in New York State. On 8 Apr 2005, the State Department of Agriculture and
Markets (DAM) completed testing of the captive deer and found a total of 5
positive results for CWD in the 2 captive herds.
DEC, along with the U.S. Department of Agriculture's Wildlife Services
program, completed intensive monitoring on 30 Apr 2005. The effort resulted in
290 samples of wild deer from Oneida County, 2 from neighboring Madison County,
and 25 wild deer from the Town of Arietta, Hamilton County. Since 2002, DEC has
conducted statewide sampling of wild deer for CWD. When combined with sampling
efforts in Oneida and Hamilton Counties, DEC has collected more than 3700
samples from wild white-tailed deer.
DEC and DAM will continue public outreach to interested parties in central
New York to help educate citizens on CWD and to discuss next steps to be taken.
The agencies will hold a public meeting on Thu 12 May 2005, at 7 p.m. in the
Vernon-Verona-Sherrill High School Auditorium, located on State Highway 31 in
the Town of Verona. In addition, DEC and DAM will conduct additional outreach
and continue to aggressively pursue inspection and enforcement across the State.
DAM continues to investigate, sample and test white-tailed deer from 2 captive
herds directly associated with the 2 herds that were confirmed positive for CWD
in Oneida County. Results for these sampling efforts will be announced when
available.
Statewide sampling for CWD -- which has resulted in more than 1000 tests
each year -- will be increased to closely monitor the distribution and
prevalence of CWD in wild deer. In addition, DEC has implemented emergency
regulations regarding the handling, transport and management of deer in the
State. The emergency regulations are currently in effect and represent an
aggressive response to the recent discovery of chronic wasting disease (CWD) in
Oneida County. DEC's emergency regulations are designed to ensure the proper
handling of deer and prevent further spread of CWD in the wild herd. The
emergency regulations are effective for 90 days. In addition, DEC will begin the
process of developing permanent regulations, which will appear in the State
Register and include a 45-day public comment period.
CWD is a transmissible disease that affects the brain and central nervous
system of certain deer and elk. There is no evidence that CWD is linked to
disease in humans or domestic livestock other than deer and elk. More
information on CWD can be found at DEC's website at <http://www.dec.state.ny.us/website/dfwmr/wildlife/deer/currentcwd.html>

HD.13: CWD infection in the spleen of humanized transgenic mice
Liuting Qing and Qingzhong Kong
Case Western Reserve University; Cleveland, OH USA
Chronic wasting disease (CWD) is a widespread prion disease in free-ranging
and captive cervid species in North America, and there is evidence suggesting
the existence of multiple CWD strains. The susceptibility of human CNS and
peripheral organs to the various CWD prion strains remains largely unclear.
Current literature suggests that the classical CWD strain is unlikely to infect
human brain, but the potential for peripheral infection by CWD in humans is
unknown. We detected protease-resistant PrpSc in the spleens of a few humanized
transgenic mice that were intracerebrally inoculated with natural CWD isolates,
but PrpSc was not detected in the brains of any of the CWD-inoculated mice. Our
ongoing bioassays in humanized Tg mice indicate that intracerebral challenge
with such PrpSc-positive humanized mouse spleen already led to prion disease in
most animals.
***These results indicate that the CWD prion may have the potential to
infect human peripheral lymphoid tissues.

Background. Bovine spongiform encephalopathy (BSE) is a known zoonotic
prion disease, resulting in variant Creurzfeldt- Jakob disease (vCJD) in humans.
In contrast, classical scrapie in sheep is thought to offer little or no danger
to human health. However, a widening range of prion diseases have been
recognized in cattle, sheep and deer. The risks posed by individual animal prion
diseases to human health cannot be determined a priori and are difficult to
assess empirically. The fundamemal event in prion disease pathogenesis is
thought to be the seeded conversion of normal prion protein (PrPC) to its
pathological isoform (PrPSc). Here we report the use of a rapid molecular
conversion assay to test whether brain specimens from different animal prion
diseases are capable of seeding the conversion of human PrPC ro PrPSc.
Material and Methods. Classical BSE (C-type BSE), H-type BSE, L-type BSE,
classical scrapie, atypical scrapie, chronic wasting disease and vCJD brain
homogenates were tested for their ability to seed conversion of human PrPC to
PrPSc in protein misfolding cyclic amplification (PMCA) reactions. Newly formed
human PrPSc was detected by protease digestion and western blotting using the
antibody 3F4.
Results. C-type BSE and vCJD were found to efficiently convert PrPC to
PrPSc. Scrapie failed to convert human PrPC to PrPSc. Of the other animal prion
diseases tested only chronic wasting disease appeared to have the capability ro
convert human PrPC to PrPSc. The results were consistent whether the human PrPC
came from human brain, humanised transgenic mouse brain or from cultured human
cells and the effect was more pronounced for PrPC with methionine at codon 129
compared with that with valine.
Conclusion. Our results show that none of the tested animal prion disease
isolates are as efficient as C-type BSE and vCJD in converting human prion
protein in this in vitro assay.
***However, they also show that there is no absolute barrier ro conversion
of human prion protein in the case of chronic wasting disease.

*** The potential impact of prion diseases on human health was greatly
magnified by the recognition that interspecies transfer of BSE to humans by beef
ingestion resulted in vCJD. While changes in animal feed constituents and
slaughter practices appear to have curtailed vCJD, there is concern that CWD of
free-ranging deer and elk in the U.S. might also cross the species barrier.
Thus, consuming venison could be a source of human prion disease. Whether BSE
and CWD represent interspecies scrapie transfer or are newly arisen prion
diseases is unknown. Therefore, the possibility of transmission of prion disease
through other food animals cannot be ruled out. There is evidence that vCJD can
be transmitted through blood transfusion. There is likely a pool of unknown size
of asymptomatic individuals infected with vCJD, and there may be asymptomatic
individuals infected with the CWD equivalent. These circumstances represent a
potential threat to blood, blood products, and plasma supplies.

the original posting at http://muledeercountry.com/forum/desert-mule-deer/texas/.
Wildlife officials are reminding mule deer hunters and landowners in far
West Texas about the protocols developed as part of Texas Parks and Wildlife
Department’s (TPWD) Chronic Wasting Disease management plan. The plan includes
mandatory check stations for harvested mule deer taken inside the CWD
Containment Zone, which covers portions of Hudspeth, Culberson, and El Paso
counties. See map of CWD zones at http://www.tpwd.state.tx.us/cwd.
The management plan was implemented after CWD was detected in tissue
samples from two mule deer in far West Texas during the summer of 2012. Those
were the first cases of CWD detected in Texas deer.
Nearly 300 tissue samples were collected from hunter harvested mule deer
from the Trans Pecos ecoregion during the 2012-13 season for CWD testing. Texas
A&M Veterinary Medical Diagnostic Laboratory and National Veterinary
Services Laboratories (NVSL) confirmed CWD in four of those samples. All
CWD-positive deer were harvested within the CWD Containment Zone.
Of 298 deer sampled during last hunting season, 107 were harvested in the
Containment Zone, 93 were harvested in the adjacent High Risk Zone, 25 were
harvested in the Buffer Zone, and 73 deer were harvested outside of the CWD
zones. Nineteen of the samples collected from the Containment Zone were from
deer harvested in the Hueco Mountains.
Hunters taking mule deer inside the Containment Zone during the 2013
general mule deer hunting season, Nov. 22 – Dec. 8, are required to submit their
harvest (unfrozen head) for CWD sampling at mandatory check stations within 24
hours of harvest.
“We recommend hunters in the Containment Zone and High Risk Zone quarter
deer in the field and leave all but the quarters, backstraps, and head at the
site of harvest if it is not possible to bury the inedible carcass parts at
least 6 feet deep on the ranch or take them to a landfill,” said Shawn Gray,
Mule Deer Program Leader for TPWD.
Mandatory check stations will be open from 9 a.m. to 9 p.m. Nov. 22 – Dec.
9. Stations will be located in Cornudas at May’s Café (on US 62-180) and in Van
Horn at Van Horn Convention Center (1801 West Broadway).
Hunters who harvest deer in the Containment Zone outside the general season
under the authority of MLDP (Managed Lands Deer Permits) will need to call TPWD
at (512) 221-8491 the day the deer is harvested to make arrangements to have the
deer sampled for CWD.
In addition to protocols within the Containment Zone, TPWD has established
check stations for voluntary CWD sampling for deer harvested in other parts of
West Texas. Biologists have been collecting mule deer harvest data in the region
since 1980 and this year CWD sampling will be offered in addition to age and
weight measurements.
Voluntary check stations will be established at the following locations
during the first three weekends of the general season, Saturday through Monday
(Nov. 23–25, Nov. 30–Dec. 2 and Dec. 6–8), from 9 a.m. – 5 p.m. Saturday and
Sunday and 9 a.m. – 1 p.m. Monday:
Midland at Naturally Fresh (Deer Processor) (1501 Elwyn)
Bakersfield at Chevron Station (south of I10; Exit 294)
Sanderson at Slim’s Auto Repair (823 West Oak; Intersection of US 90 and
285)
Alpine at Hip-O Taxidermy (east side of town on US 90, across from Dairy
Queen)
All deer brought to the check stations this season will be aged as part of
our CWD surveillance. Additional biological information such as antler
measurements and field dressed weights will also be collected as time
allows.
TPWD has tested almost 30,000 wild hunter-harvested and road-killed deer in
Texas since 2002. The captive-deer industry in Texas has submitted more than
7,400 CWD test results as well.
“CWD has not been detected anywhere outside of the Hueco Mountains,” said
Mitch Lockwood, Big Game Program Director with TPWD. “But adequate surveillance
in that part of West Texas depends on check stations and we appreciate the
cooperation and active participation of hunters and landowners in this area.

Dear Dr. Singletary,
In Fiscal Year 2001, seven deer from Texas were tested by the National
Veterinary Services Laboratory (NVSL) for CWD (5 fallow deer and 2 white-tailed
deer). In Fiscal Year 2002, seven elk from Texas were tested at NVSL (no deer).
During these two years, an additional six elk and one white-tailed deer were
tested at the Texas Veterinary Medical Diagnostic Laboratory (TVMDL). In Fiscal
Year 2002, four white-tailed deer (free-ranging clinical suspects) and at least
eight other white-tailed deer have been tested at TVMDL. One elk has been tested
at NVSL. All of these animals have been found negative for CWD. Dr. Jerry Cooke
of the Texas Parks and Wildlife Department also has records of 601 clinically
ill white-tailed deer which were necropsied at Texas A&M during the late
1960's and early 1970's, and no spongiform encepalopathies were noted.
Thank you for your consideration.

In the Archives of Neurology you quoted (the abstract of which was attached

That assumption would be wrong. I encourage you to read the whole article

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

HD.13: CWD infection in the spleen of humanized transgenic mice
Liuting Qing and Qingzhong Kong
Case Western Reserve University; Cleveland, OH USA
Chronic wasting disease (CWD) is a widespread prion disease in free-ranging
and captive cervid species in North America, and there is evidence suggesting
the existence of multiple CWD strains. The susceptibility of human CNS and
peripheral organs to the various CWD prion strains remains largely unclear.
Current literature suggests that the classical CWD strain is unlikely to infect
human brain, but the potential for peripheral infection by CWD in humans is
unknown. We detected protease-resistant PrpSc in the spleens of a few humanized
transgenic mice that were intracerebrally inoculated with natural CWD isolates,
but PrpSc was not detected in the brains of any of the CWD-inoculated mice. Our
ongoing bioassays in humanized Tg mice indicate that intracerebral challenge
with such PrpSc-positive humanized mouse spleen already led to prion disease in
most animals. ***These results indicate that the CWD prion may have the
potential to infect human peripheral lymphoid tissues.

Background. Bovine spongiform encephalopathy (BSE) is a known zoonotic
prion disease, resulting in variant Creurzfeldt- Jakob disease (vCJD) in humans.
In contrast, classical scrapie in sheep is thought to offer little or no danger
to human health. However, a widening range of prion diseases have been
recognized in cattle, sheep and deer. The risks posed by individual animal prion
diseases to human health cannot be determined a priori and are difficult to
assess empirically. The fundamemal event in prion disease pathogenesis is
thought to be the seeded conversion of normal prion protein (PrPC) to its
pathological isoform (PrPSc). Here we report the use of a rapid molecular
conversion assay to test whether brain specimens from different animal prion
diseases are capable of seeding the conversion of human PrPC ro PrPSc.
Material and Methods. Classical BSE (C-type BSE), H-type BSE, L-type BSE,
classical scrapie, atypical scrapie, chronic wasting disease and vCJD brain
homogenates were tested for their ability to seed conversion of human PrPC to
PrPSc in protein misfolding cyclic amplification (PMCA) reactions. Newly formed
human PrPSc was detected by protease digestion and western blotting using the
antibody 3F4.
Results. C-type BSE and vCJD were found to efficiently convert PrPC to
PrPSc. Scrapie failed to convert human PrPC to PrPSc. Of the other animal prion
diseases tested only chronic wasting disease appeared to have the capability ro
convert human PrPC to PrPSc. The results were consistent whether the human PrPC
came from human brain, humanised transgenic mouse brain or from cultured human
cells and the effect was more pronounced for PrPC with methionine at codon 129
compared with that with valine.
Conclusion. Our results show that none of the tested animal prion disease
isolates are as efficient as C-type BSE and vCJD in converting human prion
protein in this in vitro assay. ***However, they also show that there is no
absolute barrier ro conversion of human prion protein in the case of chronic
wasting disease.

How and why some misfolded proteins become horizontally transmitted agents
and occasionally cross species barriers are issues fundamental to understanding
prion disease. Chronic wasting disease (CWD) of cervids is perhaps a prototype
of horizontal prion transmission, encompassing efficient mucosal uptake,
lymphoid amplification, neuroinvasion, peripheralization, and dissemination via
mucosal excretion. Efficient mucosal transmission of CWD in deer has been
demonstrated by oral, nasal, aerosol, and indirect contact exposure. In
addition, other studies (Mathiason CK, et al.) reported at the symposium support
a significant role for pre- and/or postnatal transmission of CWD from doe to
offspring. Accumulating, yet still incomplete, evidence also suggests that the
period of relatively covert CWD infection may be longer than originally thought.
Given the above, minimally invasive sensitive assays based on body fluids from
live animals would aid substantially in understanding the biology of CWD. We
have been applying seeded realtirne quaking-induced amplification of recombinant
PrP substrates (i.e., RT-QuIC methodology) to: (1) investigate antemortem CWD
detection, and (2) model PrP-based species barriers and trans-species
adaptation-topics we previously explored using sPMCA and in vivo bioassays. At
this symposium, we report sensitive and specific detection CWD prions in saliva,
urine, blood (Mathiason lab), and rectal and pharyngeal lymph node samples
(Haley NJ, et al.) from pre-symptomatic and symptomatic experimentally and
naturally exposed deer. Other ongoing studies are employing RT-QuIC methodology
to model amplification barriers among CWD, FSE, BSE, and CJD prions using
cervine, feline, bovine, human, and promiscuous rPrP substrates and the above
species prion seeds, cellular co-factors, and transgenic mice. Finally, in
collaboration with the Wisniewski laboratory, we are conducting of experimental
CWD vaccination studies in deer employing oral administration of an attenuated
Salmonella vector expressing cervid PrP epitopes.

While large quantities of protease resistant prion protein (PrPres) can be
demonstrated by western blot or IHC in lymphoid biopsies or post-mortem brain
tissues harvested from prion-infected animals, these conventional assays are
less reliable as means to detect the small quantities of prions thought to be
present in bodily fluids or associated with early and asymptomatic phases of TSE
disease. The Real Time-Quaking Induced Conversion (RT-QuIC) assay is capable of
detecting prions at concentrations below the level of sensitivity of
conventional assays and provides a real-time fluorescent readout negating the
use of proteases. We have made modifications to the RT-QuIC assay to utilize it
for the detection of PrPres in brain and blood harvested from various species
infected with prions. In this study, we analyzed CWD-infected deer and
CWD/TME-infected hamster whole blood to determine the effect of:
(1) various anticoagulants,
(2) freezing and
(3) NaPTA precipitation.
Brain tissue and blood collected from naive deer and hamsters served as
negative controls.
We were able to demonstrate amplifiable prions in
(1) brain and blood samples harvested from CWD/TME-infected animals,
(2) heparinized blood,
(3) frozen vs. fresh blood and
(4) NaPTA treated samples.
The RT-QuIC assay is able to detect PrPres in various species of animals
and shows promise as an antemortem diagnostic tool for blood-borne TSEs.

*** As Chronic Wasting Disease CWD rises in deer herd, what about risk for
humans?
Thursday, October 10, 2013
CJD REPORT 1994 increased risk for consumption of veal and venison and lamb
*** The potential impact of prion diseases on human health was greatly
magnified by the recognition that interspecies transfer of BSE to humans by beef
ingestion resulted in vCJD. While changes in animal feed constituents and
slaughter practices appear to have curtailed vCJD, there is concern that CWD of
free-ranging deer and elk in the U.S. might also cross the species barrier.
Thus, consuming venison could be a source of human prion disease. Whether BSE
and CWD represent interspecies scrapie transfer or are newly arisen prion
diseases is unknown. Therefore, the possibility of transmission of prion disease
through other food animals cannot be ruled out. There is evidence that vCJD can
be transmitted through blood transfusion. There is likely a pool of unknown size
of asymptomatic individuals infected with vCJD, and there may be asymptomatic
individuals infected with the CWD equivalent. These circumstances represent a
potential threat to blood, blood products, and plasma supplies.
