Chronic Wasting
Disease Tests Are Negative On Georgia Deer
With the
Georgia deer season just around the corner it is great to know
that the venison that you will harvest is safe from chronic
wasting disease. The Georgia Department of Natural Resources began
a five -year survey last fall in an attempt to determine if
Georgia’s white-tailed deer herd may have been infected with
Chronic Wasting Disease (commonly referred to as CWD). While DNR
currently has no evidence that the disease has made it into our
deer population, discoveries of the disease in Minnesota, New
Mexico and Wisconsin have proven that no state should consider
itself immune. To survey the deer herd, DNR hoped to collect
between several hundred samples of central nervous system tissue
from hunter-harvested deer last fall. Samples were tested at a
laboratory in Athens to determine if any of these animals show
signs of infection. You should not be surprised if you aren’t
familiar with CWD, it has only reached national prominence in the
past year or so although researchers have know of the disease for
about 30 years. The disease was previously known only in western
states of Colorado, Nebraska and Wyoming when last year it
suddenly turned up in routine samples taken in Wisconsin. This
alarming turn of events got national attention primarily for two
reasons. Unlike the spread of West Nile Virus which is gradually
being detected further and further west, CWD had t raveled a great
distance from the endemic area (where it had been known to exist
in a somewhat natural environment) with no warning signs. With no
live tests, no vaccines, no cure and a disease that always kills
animals that are infected, conservation agencies are concerned the
disease could ravage deer populations in the eastern US. Further
compounding the problem is that deer populations in the east may
be worse suited to naturally survive the infection due to
naturally higher deer densities (causing more rapid spread of
disease from animal to animal) and more wooded habitats making
sick deer harder to detect. CWD is one of a group of diseases
known as transmissible spongiform encephalopathies or TSEs. These
diseases can be given from one animal to the next and may not
cause the death of these animals for several years. Similar
diseases are known to occur in cattle (mad cow disease), sheep and
humans. Within an infected animal the disease causes proteins to
mutate and congregate in the brain of the animal. Holes form in
the brain around these congregations causing animals to behave
abnormally and ultimately die. The best protection for any deer
herd is to prevent the animals from being exposed.
DNRs survey
began last fall and included collection of hunter-harvested
animals. Collections were limited to six of the areas in Georgia
where the risk of introduction of CWD is considered highest.
Sampling for the first year will include sites in Dawson, Harris,
Peach, Marion, Oconee and Toombs Counties. Collection areas were
circular areas of a four-mile radius around facilities that have
purchased and imported deer in the recent past. While the purchase
of deer was legal for these facilities, the fact that these
animals may have been purchased through sale barns or other
locations where they were in contact with numerous other deer
makes these facilities higher risk than those which have not
acquired deer recently. DNR personnel will be contacting persons
in and around these areas of interest with instructions on sample
submittal for that area. DNR then processed the samples and
submitted the samples to the Southeastern Cooperative Wildlife
Disease Study laboratory in Athens, Georgia for analysis.
Even though
DNR is not expecting to find animals testing positive for CWD,
Georgians will benefit from knowing that our deer are being
sampled. If CWD is detected during the survey, Georgia will likely
benefit from the proactive survey and can take steps to control
the disease. DNR is asking Georgians to help protect against the
disease by reporting any deer that exhibit signs of excessive
salivation or urination, head tremors or emaciation to your local
DNR office. Hunters and wildlife enthusiasts alike can also help
by informing anyone who may consider illegally buying deer about
the risks of CWD and its potential impact to Georgia.
Now the first
results are in and Georgia is looking good! A total of 336 samples
were collected under this program. All samples have been tested.
The results from these samples are all non-detection of CWD. This
is certainly good news, but additional samples in future years
remain to be tested in accordance with our targeted surveillance
program.
Additionally,
necropsy animals are also being continuously submitted to
determine unexplained mortalities. Animals that were showing
clinical signs similar to those reported for CWD (excessive
salivation or urination, head tremors or emaciation) were also
tested for CWD. To date, all of these animals’ test results were
also non-detect. Again, these findings are good news and we will
continue testing suspect animals in future years. Now biologists
are suggesting that supplemental feeding of deer will increase
disease in deer. Reliable science provides support for a ban of
baiting and feeding of white-tailed deer to reduce disease risks
for Chronic Wasting Disease (CWD). Peer-reviewed research papers
published in reputable scientific journals indicate the following:
CWD is
transmitted laterally (live diseased deer infect other deer) ·
Deer can get CWD by ingesting something contaminated with the
disease prion · CWD prions may be shed in feces and saliva ·
Disease course and symptoms indicate high potential for
transmission where deer are concentrated Evidence from captive
situations indicates that deer can get CWD from highly
contaminated environments.
Baiting and
Feeding causes unnatural concentration of deer Reduction of
contact through a ban on baiting and feeding is likely very
important to eradicating or containing a CWD outbreak.
Baiting and
feeding continues to put Wisconsin’s deer herd at risk to other
serious diseases In addition, experts in CWD, wildlife disease and
deer nutrition support bans on baiting and feeding as part of a
comprehensive strategy to prevent and/or manage CWD.
Under a
baiting and feeding ban, disease outbreaks are more likely to be
smaller in scale and more apt to be contained or eliminated. With
the long CWD incubation period and other factors that make
discovery of a new outbreak difficult, an outbreak that is already
widespread when detected because of baiting and feeding may not be
able to be contained or eliminated. Gov. Sonny Perdue and House
Speaker Coleman Break Ground for New Public Fishing Area Anglers’
high hopes for future fishing opportunities became closer to
reality today as Governor Sonny Perdue, House Speaker Terry
Coleman and Senator Ross Tolleson broke ground during a ceremony
to mark the beginning of construction of the Ocmulgee Public
Fishing Area (PFA) in Bleckley and Pulaski counties. The Georgia
Department of Natural Resources, Wildlife Resources Division (WRD)
will construct and manage the proposed Ocmulgee PFA on the
state-owned Ocmulgee Wildlife Management Area. Plans for the area
include a main 106-acre lake, a separate three-acre kids fishing
lake, a boat ramp, two fishing piers, an office, storage
buildings, a pavilion/activity center and parking areas.
“Fishing is
big business in Georgia,” said Governor Sonny Perdue. “This new
fishing area will be a tremendous asset to Georgians around the
state, especially citizens in nearby Bleckley and Pulaski
counties.” “We are also pleased with WRD’s projections that the
new fishing area could generate approximately $862,000 in economic
activity each year,” added Governor Perdue.
Construction
on the lake has just begun and filling of the main lake should
take place through the spring of 2004. Fish stocking will occur
as the lake is filled and the population will develop for about a
year in the absence of fishing. If the project stays on schedule,
the PFA should be open for fishing in the spring of 2006. The kids
fishing lake will be opened as early as spring 2004 for special
events. The total cost for the proposed project including design,
wetland mitigation and archeological studies is approximately $4.2
million.
“I am very
excited about the building of this facility,” said Coleman. “The
most common reasons people do not fish and/or fish more often are
related to an inadequate supply of safe, well-managed public
fishing opportunities that are near to them. This PFA will be
within a one-hour drive of more than 100,000 anglers and 649,000
other citizens, many of who participate in some type of
wildlife-related recreation.”
It is
expected that the fishing success on this lake will be similar to
the Dodge County PFA, which has been very popular with anglers and
has even yielded a 15.5 pound largemouth bass. Hundreds of school
children will be introduced to fishing in the three-acre kids
fishing pond, which will be heavily stocked with fish to ensure
high catch rates for these young anglers. “Recent studies show
that spending time with family and friends is one of the most
important reasons people participate in fishing,” said Tolleson.
“At a time when parent/child family time has decreased
significantly, participating in outdoor recreation is one way to
strengthen the family as a unit and children as individuals.”
The main lake
will have numerous coves and points, creek channels, standing
timber and submerged humps for attracting fish. The deepest point
at the dam will be about 30 feet. The lake will be intensively
managed to provide the best possible fishing opportunities for
both bank and boat anglers. Input from local anglers and
information gathered at a public meeting have indicated that
crappie and trophy largemouth bass angling will be the primary
focus of the lake, with additional attention to bluegill,
shellcrackers and channel catfish. The area will be open from
sunrise to sunset all year long. Anglers 16 years of age or older
must possess a current Georgia fishing license and a Wildlife
Management Area (WMA) stamp in order to fish. Anglers in
possession of a one-day fishing license, Senior (65+) or Honorary
license do not have to possess a WMA stamp. Anglers may use up to
two fishing poles and any size outboard motor may be used at idle
speed.
