175 DEER TEST POSITIVE FOR CWD IN WISCONSIN

Posted Mar 18 2010 7:13pm
CWD Update: Disease Prevalence Rates Continue to Rise
News Release Published: March 15, 2010 by the South Central Region

Contact(s): Davin Lopez, CWD Project Leader, Madison: (608) 267-2948

MADISON – The Department of Natural Resources sampled and tested more than 7,100 deer during 2009 in the Chronic Wasting Disease-Management Zone (CWD-MZ), with 175 testing positive for CWD, the state agency announced today.

Test results for 2009 in the 210 square mile Western Core Area, which mainly encompasses western Dane and eastern Iowa counties, show that the overall trend in the prevalence rate – the percentage of deer testing positive for CWD – continues to increase. The Western Core Area has the highest prevalence rates in Wisconsin.

Since 2002 and despite yearly fluctuations, overall prevalence increases are apparent in all sex and age classes. Over the past eight years of DNR testing in the core area, prevalence in adult males has risen from about 10 percent to over 12 percent and in adult females from about 4 percent to about six percent. Prevalence in yearling males has increased from about 2 percent to about 4 percent and in yearling females from 2 percent to nearly 6 percent since 2002.

“Simply put, disease prevalence is higher in males than females and higher in adults than yearlings,” said Davin Lopez, DNR’s CWD project leader.

DNR biologists and technicians conducted aerial surveys this winter by helicopter and fixed wing aircraft in the CWD-MZ. The 2009 post hunt population in the CWD-MZ is estimated to be 164,300 compared to 176,300 in 2008 (minus 7 percent), about 185,000 in 2007 and 190,000 in 2006. The total deer harvest in the CWD-MZ in 2009 was 66,013.

DNR biologists know well that after eight years there’s still no easy answer to managing CWD, but they are firm in believing that based on all available evidence, the disease poses a significant threat to the long-term health of Wisconsin’s deer herd and that it is a statewide issue.

“We take our responsibility to manage the disease very seriously in order to try and protect this herd for future generations, the very definition of wildlife conservation. The goal is to minimize the distribution and intensity of CWD.”

“We must take a long-term view of disease management to accomplish this and as we revise our CWD Management Plan, we will again be looking at what this means in terms of different strategies,” added Lopez.

AS far as human transmission for CWD, you will just have to make your own minds up on that. In my opinion, there is as much evidence for transmission of cwd to humans, as there is for scrapie and BSE to humans. it's the friendly fire there from i.e. cwd exposure that concerns me the most, but the did not recall all this cwd positive elk meat FOR THE WELL BEING OF THE DEAD ELK ;

Potential Venison Exposure Among FoodNet Population Survey Respondents, 2006-2007

Ryan A. Maddox1*, Joseph Y. Abrams1, Robert C. Holman1, Lawrence B. Schonberger1, Ermias D.

The foodborne transmission of bovine spongiform encephalopathy to humans, resulting in variant Creutzfeldt-Jakob disease, indicates that humans can be susceptible to animal prion diseases. However, it is not known whether foodborne exposure to the agent causing chronic wasting disease (CWD) in cervids can cause human disease. The United States Foodborne Diseases Active Surveillance Network (FoodNet) conducts surveillance for foodborne diseases through an extensive survey administered to respondents in selected states. To describe the frequency of deer and elk hunting and venison consumption, five questions were included in the 2006-2007 FoodNet survey. This survey included 17,372 respondents in ten states: California, Colorado, Connecticut, Georgia, Maryland, Minnesota, New Mexico, New York, Oregon, and Tennessee. Of these respondents, 3,220 (18.5%) reported ever hunting deer or elk, with 217 (1.3%) reporting hunting in a CWD-endemic area (northeastern Colorado, southeastern Wyoming, and southwestern Nebraska). Of the 217 CWD-endemic area hunters, 74 (34.1%) were residents of Colorado. Respondents reporting hunting were significantly more likely to be male than female (prevalence ratio: 3.3, 95% confidence interval: 3.1-3.6) and, in general, older respondents were significantly more likely to report hunting than younger respondents. Venison consumption was reported by more than half (67.4%) of the study population, and most venison consumers (94.1%) reported that at least half of their venison came from the wild. However, more than half (59.1%) of the consumers reported eating venison only one to five times in their life or only once or twice a year. These findings indicate that a high percentage of the United States population engages in hunting and/or venison consumption. If CWD continues to spread to more areas across the country, a substantial number of people could potentially be exposed to the infectious agent.

Dear Sir/Madam,

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

attached to your email), we did not say CWD in humans will present like

variant CJD.

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

article and call me if you have questions or need more clarification

(phone: 404-639-3091). Also, we do not claim that "no-one has ever been

infected with prion disease from eating venison." Our conclusion stating

that we found no strong evidence of CWD transmission to humans in the

article you quoted or in any other forum is limited to the patients we

investigated.

that it is not dangerous to humans is thin.

Chronic wasting disease (CWD) of deer and elk is endemic in a tri-corner area of Colorado, Wyoming, and Nebraska, and new foci of CWD have been detected in other parts of the United States. Although detection in some areas may be related to increased surveillance, introduction of CWD due to translocation or natural migration of animals may account for some new foci of infection. Increasing spread of CWD has raised concerns about the potential for increasing human exposure to the CWD agent. The foodborne transmission of bovine spongiform encephalopathy to humans indicates that the species barrier may not completely protect humans from animal prion diseases. Conversion of human prion protein by CWD-associated prions has been demonstrated in an in vitro cell-free experiment, but limited investigations have not identified strong evidence for CWD transmission to humans. More epidemiologic and laboratory studies are needed to monitor the possibility of such transmissions.

Suggested citation for this article

The transmission of the prion disease bovine spongiform encephalopathy (BSE) to humans raises concern about chronic wasting disease (CWD), a prion disease of deer and elk. In 7 Colorado counties with high CWD prevalence, 75% of state hunting licenses are issued locally, which suggests that residents consume most regionally harvested game. We used Colorado death certificate data from 1979 through 2001 to evaluate rates of death from the human prion disease Creutzfeldt-Jakob disease (CJD). The relative risk (RR) of CJD for CWD-endemic county residents was not significantly increased (RR 0.81, 95% confidence interval [CI] 0.40-1.63), and the rate of CJD did not increase over time (5-year RR 0.92, 95% CI 0.73-1.16). In Colorado, human prion disease resulting from CWD exposure is rare or nonexistent. However, given uncertainties about the incubation period, exposure, and clinical presentation, the possibility that the CWD agent might cause human disease cannot be eliminated.

TEN KANSAS DEER CONFIRMED POSITIVE IN CWD TESTS

http://chronic-wasting-disease.blogspot.com/2010/03/ten-kansas-deer-confirmed-positive-in_04.html



In Confidence - Perceptions of unconventional slow virus diseases of animals in the USA - APRIL-MAY 1989 - G A H Wells

3. Prof. A Robertson gave a brief account of BSE. The US approach was to accord it a very low profile indeed. Dr. A Thiermann showed the picture in the ''Independent'' with cattle being incinerated and thought this was a fanatical incident to be avoided in the US at all costs. BSE was not reported in the USA.

snip...

CWD occurred principally in two locations, this one at Sybille and in a similar faccility at Fort Collins, Colorado, some 120 miles southwest. It was estimated that in total probably 60-70 cases of CWD have occurred.

It was difficult to gain a clear account of incidence and temporal sequence of events (-this presumably is data awaiting publication - see below) but during the period 1981-1984, 10-15 cases occurred at the Sybille facility.

The moribidity amongst mule deer in the facilities ie. those of the natural potentially exposed group has been about 90% with 100% mortality.

snip...

Spraker suggested an interesting explanation for the occurrence of CWD. The deer pens at the Foot Hills Campus were built some 30-40 years ago by a Dr. Bob Davis. At or abut that time, allegedly, some scrapie work was conducted at this site. When deer were introduced to the pens they occupied ground that had previously been occupied by sheep.
