MADISON - Two deer have tested positive for chronic wasting disease, one
each in Portage and Juneau Counties, reports the state Department of Natural
Resources. These are the first positives in wild deer populations for both
counties.
“Any CWD positive in a new county is noteworthy, but neither of these
positives was completely unexpected,” said Kris Belling, DNR regional wildlife
program manager. “We’ve been performing surveillance in Juneau County due to the
proximity of the CWD management zone boundary and we’ve been sampling in Portage
County for 10 years after positives were discovered on a former game
farm.”
The two CWD-positive deer were harvested by gun hunters on Nov. 18 and
sampled by DNR staff. The Portage County positive was a 1.5-year-old doe,
harvested in deer management unit (DMU) 57A, close to the Mead Wildlife Area.
The central Juneau County deer was a 4-to 5-year-old buck, harvested in deer
management unit DMU 54B, less than two miles from the CWD management zone
boundary.
These sampling results do not change the remaining days of the late archery
hunting season nor does it change the current CWD management zone boundary.
Baiting and feeding of deer, as well as deer rehabilitation, is already banned
in these counties.
DNR has conducted annual surveillance in Portage County since 2002, when a
captive game farm in the southeast part of the county experienced CWD positives
in its herd. The disease was confirmed in a second captive herd in northwest
Portage County in 2008. Since 2002, 1,506 wild deer have been tested.
Juneau County was part of DNR’s “weighted” surveillance strategy, focusing
on older bucks because they have a higher probability of being infected with
disease. The weighted approach increases the likelihood of early detection in
periphery areas outside the CWD management zone.
“We thank all hunters who have brought deer in for voluntary CWD testing,”
said Belling. “This cooperation is essential for detecting and tracking the
prevalence of this disease.”
Sampling of deer in Juneau and Portage Counties is voluntary and will
continue through the end of the late archery hunt, Jan. 6. Juneau County area
bow hunters interested in having their deer sampled are encouraged to contact
Jon Robaidek, local DNR biologist at 608-339-4819. Portage County area bow
hunters can contact the Mead Wildlife Area office for more information on having
their deer sampled, 715-457-6771.
“It is too soon to draw any conclusions from these most recent positives,”
said Belling. “We will process remaining samples from these counties and discuss
next steps once all results are in. We will keep the public informed and
involved as we learn more.”

2010 WISCONSIN CAPTIVE DEER ESCAPES

C. & D. Captive Cervid and Law Enforcement Update (11:10 AM)- Warden
Pete Dunn gave the captive cervid farm update. There were 26 reported escape
incidents so far this year, this amounted to 20 actual confirmed escape
incidents because 3 were previously reported, 2 were confirmed as wild deer, and
1 incident was not confirmed. Approximately 30% of these escapes were caused by
gates being left open and the other 70% resulted from bad fencing or fence
related issues. The 20 actual confirmed escape incidents amounted to 77 total
animals. 50 of the escaped animals were recovered or killed and 27 were not
recovered and remain unaccounted for. Last year the CWD Committee passed a
resolution to require double gates, but this has not gone into effect yet.
Questions were raised by the committee about double fencing requirements? Pete
responded that double fencing has not been practical or accepted by the
industry. The DNR has the authority to do fence inspections. ?If a fence fails
to pass the inspection the fencing certificate can be revoked and the farmer can
be issued a citation. This year three citations and one warning have been issued
for escapes.
Pete reviewed the reporting requirements for escape incidents that these
must be reported within 24 hours. The farmer then has 72 hours to recover the
animals or else it will affect the farm’s herd status and ability to move
animals. Davin proposed in the 15 year CWD Plan that the DNR take total control
and regulatory authority over all deer farm fencing. Larry Gohlke asked Pete
about the reliability for reporting escapes? Pete said that the majority of
escapes were reported by the farmer, but it is very difficult to determine when
an escape actually occurred. Pete said that they are more concerned that an
escape is reported and not that it is reported at the exact time that it
happened.

THE states are going to have to regulate how many farms that are allowed,
or every state in the USA will wind up being just one big private fenced in game
farm. kind of like they did with the shrimping industry in the bays, when there
got to be too many shrimp boats, you stop issuing permits, and then lower the
exist number of permits, by not renewing them, due to reduced permits issued.
how many states have $465,000., and can quarantine and purchase there
from, each cwd said infected farm, but how many states can afford this for all
the cwd infected cervid game ranch type farms ???
11,000 game farms X $465,000., do all these game farms have insurance to
pay for this risk of infected the wild cervid herds, in each state ???

CHRONIC WASTING DISEASE CWD WISCONSIN Almond Deer (Buckhorn Flats) Farm
Update DECEMBER 2011
The CWD infection rate was nearly 80%, the highest ever in a North
American captive herd.
RECOMMENDATION: That the Board approve the purchase of 80 acres of land
for $465,000 for the Statewide Wildlife Habitat Program in Portage County and
approve the restrictions on public use of the site.

Synopsis
Occurrence, Transmission, and Zoonotic Potential of Chronic Wasting Disease
snip...
Most epidemiologic studies and experimental work have suggested that the
potential for CWD transmission to humans is low, and such transmission has not
been documented through ongoing surveillance (2,3). In vitro prion replication
assays report a relatively low efficiency of CWD PrPSc-directed conversion of
human PrPc to PrPSc (30), and transgenic mice overexpressing human PrPc are
resistant to CWD infection (31); these findings indicate low zoonotic potential.
However, squirrel monkeys are susceptible to CWD by intracerebral and oral
inoculation (32). Cynomolgus macaques, which are evolutionarily closer to humans
than squirrel monkeys, are resistant to CWD infection (32). Regardless, the
finding that a primate is orally susceptible to CWD is of concern...
snip...
Reasons for Caution There are several reasons for caution with respect to
zoonotic and interspecies CWD transmission. First, there is strong evidence that
distinct CWD strains exist (36). Prion strains are distinguished by varied
incubation periods, clinical symptoms, PrPSc conformations, and CNS PrPSc
depositions (3,32). Strains have been identified in other natural prion
diseases, including scrapie, BSE, and CJD (3). Intraspecies and interspecies
transmission of prions from CWD-positive deer and elk isolates resulted in
identification of >2 strains of CWD in rodent models (36), indicating that
CWD strains likely exist in cervids. However, nothing is currently known about
natural distribution and prevalence of CWD strains. Currently, host range and
pathogenicity vary with prion strain (28,37). Therefore, zoonotic potential of
CWD may also vary with CWD strain. In addition, diversity in host (cervid) and
target (e.g., human) genotypes further complicates definitive findings of
zoonotic and interspecies transmission potentials of CWD.
Intraspecies and interspecies passage of the CWD agent may also increase
the risk for zoonotic CWD transmission. The CWD prion agent is undergoing serial
passage naturally as the disease continues to emerge. In vitro and in vivo
intraspecies transmission of the CWD agent yields PrPSc with an increased
capacity to convert human PrPc to PrPSc (30). Interspecies prion transmission
can alter CWD host range (38) and yield multiple novel prion strains (3,28). The
potential for interspecies CWD transmission (by cohabitating mammals) will only
increase as the disease spreads and CWD prions continue to be shed into the
environment. This environmental passage itself may alter CWD prions or exert
selective pressures on CWD strain mixtures by interactions with soil, which are
known to vary with prion strain (25), or exposure to environmental or gut
degradation.
Given that prion disease in humans can be difficult to diagnose and the
asymptomatic incubation period can last decades, continued research,
epidemiologic surveillance, and caution in handling risky material remain
prudent as CWD continues to spread and the opportunity for interspecies
transmission increases. Otherwise, similar to what occurred in the United
Kingdom after detection of variant CJD and its subsequent link to BSE, years of
prevention could be lost if zoonotic transmission of CWD is subsequently
identified,...
