Depopulation Plan Being Developed for Captive Deer Facility in Macon County after second CWD positive confirmation

December 30, 2011


Depopulation Plan Being Developed for Captive Deer Facility in Macon County


The Missouri Department of Agriculture is finalizing a depopulation and management plan for an approximately 3,000 acre captive wildlife hunting facility in northern Missouri following two positive tests for Chronic Wasting Disease. The facility, operated by Heartland Wildlife Ranches, LLC, is home to white-tail deer, elk and red deer.


The plan includes a requirement to depopulate and test all remaining animals for CWD, as well as restrictions on the future movement of animals into the facility. The plan follows multiple positive CWD tests indentified through random surveillance and extends the facility's current quarantine until all animals have been depopulated and tested for the disease.


In October, MDA received results from the USDA National Veterinary Services Laboratory in Ames, Iowa indicating that a captive white-tail deer harvested in the Macon County facility tested positive for CWD. The animal that tested positive was inspected as part of the State's CWD surveillance and testing program. A second positive test result on a captive white-tail deer within the same facility was verified late this week.


"This plan is an important step forward as we continue working to ensure that this situation is addressed quickly and effectively and that the health of Missouri's cervids is protected from this disease," said State Veterinarian Dr. Linda Hickam.


The State's CWD Contingency Plan was developed in 2002 and revised in 2003 by the Cervid Health Committee, a task force comprised of industry representatives, veterinarians and staff from the departments of Agriculture, Conservation and Health and Senior Services and the U.S. Department of Agriculture.


In February 2010 a case of CWD was confirmed in Linn County on a captive hunting preserve operated by the same entity, Heartland Wildlife Ranches, LLC. The Linn County facility was depopulated and no further infection was identified at that facility.


CWD is transmitted by live animal to animal contact or soil to animal contact. The disease was first recognized in 1967 in captive mule deer in the Colorado Division of Wildlife captive wildlife research facility in Fort Collins, Colorado. CWD has been documented in deer and/or elk in Colorado, Illinois, Kansas, Maryland, Michigan, Minnesota, Montana, Nebraska, New Mexico, New York, North Dakota, Oklahoma, South Dakota, Utah, Virginia, West Virginia, Wisconsin, and the Canadian Provinces of Alberta and Saskatchewan. There has been no evidence that the disease can be transmitted to humans.


CWD is a neurological disease found in deer, elk and moose; it has not been reported in humans or non-cervid animals.


For more information on CWD, contact Missouri's State Veterinarian Dr. Linda Hickam at (573) 751-3377 or visit the Department online at http://www.mda.mo.gov.

Chronic Wasting Disease discovered on game farm Saskatchewan Wednesday Dec. 21, 2011

Chronic Wasting Disease discovered on game farm

CTV Saskatoon

Date: Wednesday Dec. 21, 2011 5:55 PM CST

Chronic wasting disease has been discovered on another game farm in Saskatchewan. It is the fourth case in the province so far this year.

The latest case involves a white tail deer from a farm in the Prince Albert area. The animal was discovered to be carrying the disease through a mandatory testing program for all animals over the age of 12 months that die on farms.

Canada Food Inspection Agency scientists say the disease poses very little risk to humans.

However, they say to prevent the spread of CWD to other animals or farms it is necessary to slaughter the entire herd.

Alex McIsaac, from CIFA, says slaughter is the only way to do an accurate test. "Unfortunately we don't have a live animal test at this time so that's the only way we can determine how far it has spread, unfortunately it's by destroying animals and using this post-mortem sample."

Saskatchewan deer tests positive for fatal disorder

CWD case doesn't raise concern with CFIA

Reported by Brent Bosker First Posted: Dec 20, 2011 8:46am

Chronic Wasting Disease (CWD) has resurfaced in Saskatchewan.

According to the Canadian Food Inspection Agency (CFIA), a white tail deer tested positive for the fatal disorder last month on a farm in the Prince Albert district.

The farm where the deer tested positive has been quarantined and the remainder of the herd will be destroyed.

The case isn’t raising any concern with the CFIA who monitors and investigates cases.

“Basically this is about what we would expect to see,” said Alex McIsaac, veterinarian disease control specialist with CFIA.

“We find these cases through surveillance … it’s a mandatory requirement for cervid producers in Saskatchewan to submit heads from animals over 12 months of age that die unexpectedly,” McIssac said.

CWD is a degenerative disease that affects the central nervous system of cervids such as elk, moose and deer.

The disease is a spongy type of legion on the brain that McIssac said causes a number of symptoms.

“We would see a lack of coordination, difficulty walking, separation from herd (so now they don’t feel they’re a part of the herd they’re a little nervous about where they are), excess of salivation (so they drool a lot), depression … and unusual behavior.”

This case comes six months after the last case was reported and is the fourth one this year.

Since surveillance began in 1996 there have been 66 cases across Canada, predominantly in Saskatchewan.

Saskatchewan had five cases in 2010 and two in 2009.

Herds infected with Chronic Wasting Disease in Canada in 2011

The CFIA works with provincial governments and industry to conduct regular CWD surveillance. Ongoing provincial surveillance for CWD varies with each particular province's perceived threat and infection status. Testing is mandatory in Manitoba, Saskatchewan, Alberta and the Yukon; it is voluntary elsewhere.

In addition, CWD is a reportable disease under the Health of Animals Regulations. This means that all suspected cases must be reported to the CFIA.

The following table lists domestic cervid herds confirmed to be infected with CWD in Canada in 2011.

Current as of: 2011-11-30

SCRAPIE CANADA UPDATE Current as of 2010-07-31

The following table lists sheep flocks and/or goat herds confirmed to be infected with scrapie in Canada in 2010.

Current as of: 2010-07-31

http://nor-98.blogspot.com/2010/08/scrapie-canada-update-current-as-of.html



Increased Atypical Scrapie Detections

Press reports indicate that increased surveillance is catching what otherwise would have been unreported findings of atypical scrapie in sheep. In 2009, five new cases have been reported in Quebec, Ontario, Alberta, and Saskatchewan. With the exception of Quebec, all cases have been diagnosed as being the atypical form found in older animals. Canada encourages producers to join its voluntary surveillance program in order to gain scrapie-free status. The World Animal Health will not classify Canada as scrapie-free until no new cases are reported for seven years. The Canadian Sheep Federation is calling on the government to fund a wider surveillance program in order to establish the level of prevalence prior to setting an eradication date. Besides long-term testing, industry is calling for a compensation program for farmers who report unusual deaths in their flocks.

The most recent assessments (and reassessments) were published in June 2005 (Table I; 18), and included the categorisation of Canada, the USA, and Mexico as GBR III. Although only Canada and the USA have reported cases, the historically open system of trade in North America suggests that it is likely that BSE is present also in Mexico.

CWD UTAH San Juan deer hunting unit

Posted Friday, 23 December 2011 14:49

Chronic Wasting Disease in new area


Disease doesn't affect people, but it's fatal to deer


A deer infected with chronic wasting disease has been found in a new area in Utah. That's not a surprise, though — the new area is next to an area where the disease has been for years.

Technicians at the Utah Veterinary Diagnostic Laboratory in Logan have finished testing tissue samples taken from more than 1,200 deer, elk and moose this fall.


Hunters across Utah took the animals, and biologists with the Division of Wildlife Resources collected the samples.


One of the deer that was taken on the San Juan deer hunting unit in southeastern Utah tested positive for the disease. This is the first time a deer from the unit has tested positive for chronic wasting disease (CWD).


Leslie McFarlane, wildlife disease coordinator for the DWR, says she's not surprised that a deer from the San Juan unit tested positive for CWD. "We've found deer with CWD on the La Sal Mountains," she says. "The La Sal Mountains are just north of the San Juan unit."


Most deer are disease free


Fortunately for Utah's deer herds, CWD is not widespread in Utah.


Since 2002, almost 19,000 deer have been tested in the state. Of the nearly 19,000 deer, only 54 tested positive for CWD.


The 54 deer came from three major areas in Utah:


Area Number of deer


Southeastern Utah 38


Central Utah 10


Northeastern Utah 6


One elk, no moose


To date, only one elk — a cow taken on the La Sal Mountains in November 2009 — has tested positive for the disease.


CWD has never been found in a moose in Utah.

NATURAL RESOURCES BOARD AGENDA ITEM

SUBJECT: Information Item: Almond Deer Farm Update

FOR: DECEMBER 2011 BOARD MEETING

TUESDAY

TO BE PRESENTED BY / TITLE: Tami Ryan, Wildlife Health Section Chief

SUMMARY:

2.8.2

Item No.

In April 20 II, the Natural Resources Board approved the Department purchase of a former deer farm known as Buckhorn Flats in Portage County. Following acquisition the property officially became a Bureau of Wildlife Management program property. Staff in the Bureau's Wildlife Health Section, the West Central District, and Northeast District have taken steps towards public outreach with the local community, developed a property managment plan and biosecurity protocols, are working towards the installation of a secondary fence, and are awaiting research proposals that will advance the scientific understanding of Chronic Wasing Disease.

CORRESPONDENCE/MEMORANDUM-------------

DATE: November 21, 20 ll FILE REF: 2300

TO: Natural Resources Board

FROM: Cathy Stepp

SUBJECT: Almond Deer Farm Update

The first case of Chronic Wasting Disease (CWD) among Wisconsin's farm-raised deer occurred in a white-tailed deer buck shot by a hunter at the property (formerly known as Buckhorn Flats) in September 2002. This situation prompted the eventual depopulation of the entire farm. The deer, a mix of does and yearlings, were destroyed on January 17, 2006- 4 years later- by U.S. Department of Agriculture shooters under a USDA agreement with the farm owner. Sixty of the 76 animals tested positive for CWD. The 76 deer constituted the breeding herd in the breeding facility on the farm. The property also had a hunting preserve until 2005. Four deer, two does and two fawns, the only deer remaining in the former preserve, were killed and tested as well. CWD was not detected in those animals. The total number of deer to test positive from this farm from the initial discovery to final depopulation is 82. The nearly 80% prevalence rate discovered on Buckhorn Flats is the highest prevalence recorded in any captive cervid operation in North America.

The DNR acquired the property on April 13, 20ll. After extensive consideration and pursuit of several options, it was decided that purchasing the property and subsequent management of the property is the only realistic option to keep the fences intact. Wisconsin's wild white-tailed deer herd is one of the state's most valuable natural resources, and those deer are a valuable resource of recreational, economic, and ecological significance to all citizens of the state. CWD is a serious long-term threat to Wisconsin's deer herd and the future of Wisconsin's hunting traditions. Over 1,200 free-ranging deer have been tested since 2002 in Portage County with no detections of CWD. We have very high levels of confidence that CWD does not occur in the free-ranging herd in this area. This is of particular significance considering this farm is located 60 miles north of any known occurrence of CWD in wild deer.

The Hall farm is the most concerning of the depopulated game farms in Wisconsin because of its potential high level of soil contamination. Similar concerns exist to some degree for all nine positive farms and any future farms in which CWD positive cervids are found. However, Buckhorn Flats is a unique situation due to the nearly 80% prevalence rate that occurred there, which is the highest infection rate in a captive cervid farm in North America and perhaps the world. The property has undergone cleaning and disinfection per USDA guidelines. Under the established premise plan, no species of cervids could be brought onto the property for five years, and fences were to be maintained to keep free-ranging deer from entering the property. The premise plan expired on May 24, 20ll. Despite this five year premise plan and site decontamination, the department had serious concerns over the bioavailability of infectious prions at this site to free-ranging white-tailed deer should the fences be removed or otherwise compromised.



Based on current scientific knowledge, CWD prions are known to persist in the environment for at least 3 years and potentially much longer. Evidence of environmental transmission was documented in a Colorado research facility where mule deer became infected with CWD. Furthermore, the likely transmission of CWD via soil is corroborated by recent studies that show that prions bind to soil components with high affinity and are not easily removed by water. These findings suggest that soil may contribute more significantly to TSE transmission than previously recognized.



Department Actions to Date

The DNR has taken steps to inform the public regarding the background of the Almond Farm as well as future plans for the property. A secondary fence, research, and occupancy of the house are all topics of interest. A description of each topic is identified below:

A. A Property Management Plan was developed to provide a background and future plans for the property. Chapters within the plan include a description of the property, research opportunities, facilities, public communications, and biosecurity protocols (see attachment).

B. The DNR held a public meeting the evening of July 28th at the Almond-Bancroft School to discuss the recent acquisition of the deer farm formerly known as Buckhorn Flats. Twenty-nine people signed in and stayed for the 2-hour duration including local deer farmers, conservation congress delegates, etc. Following 45 minutes of presentation, the meeting focused on the question and answer period. The DNR also asked for public input regarding how they could help in varying capacities at the Almond Farm (see attachment).

C. The DNR will begin timber removal from outside the fence this winter. Timber removal from inside the fence has begun with hazardous trees removed. The construction of a second fence 10 – 12 feet outside the present fence will begin in the spring. This will add an additional level of security for keeping wild deer from entering the farm and maintain the integrity of the perimeter (see attachment).

D. The DNR plans to use the Almond Farm as a CWD research facility. Because the question of how long a contaminated site is a risk to deer is of national and international interest, there may be opportunities for research and funding at this facility. One way to potentially assess whether there is a risk to deer from the Almond Farm is to conduct bioassays focusing on prions persisting in soil and what role environmental contamination plays in disease transmission. A proposal is pending from the University of Wisconsin – Stevens Point that concerns prion degradation via composting. The group is seeking additional funding from the University of Wisconsin – Madison and representatives in Canada. USGS is also contemplating a proposal contingent on funding from their pending federal budget. Any proposed research that includes bringing captive cervids onto the property will be thoroughly reviewed by the CWD Research Committee consisting of the Wildlife Health Team, the Wildlife Policy Team, and Department administration as well as external CWD experts prior to permission being granted to ensure that the health of the wild deer herd will not be endangered. The double fencing described above will be critical to minimize the risk of ingress of free-ranging and egress of any experimental captive cervids. E. The house is rented and currently occupied by a Northeast district wildlife employee. The Lessee agrees to perform weekly fence inspections to insure that the fence integrity has not been compromised. The Lessee also pays for all utilities, and will provide lawn care, snow removal, gutter cleaning, and other miscellaneous maintenance as needed. In exchange for these services the monthly rental fee has been waived. It is agreed that the Lessor and the Lessee shall review said waiver of the monthly rental charge at the end of every twelve months that this lease is in effect (see attachment).

CHAPTER ONE

BACKGROUND ; SUPPORTING

INFORMATION

Background

The first case of CWD among Wisconsin’s farm-raised deer occurred in a white-tailed deer buck shot by a hunter at Buckhorn Flats in September 2002. This situation prompted the eventual depopulation of the entire farm. The deer, a mix of does and yearlings, were destroyed on January 17, 2006 by U.S. Department of Agriculture shooters under a USDA agreement with the farm owner, Stan Hall. Tissue samples were sent to the Wisconsin Veterinary Diagnostic Laboratory for initial screening tests and to the USDA National Veterinary Services Laboratories in Ames, Iowa, for confirmation.

These laboratory results show that 60 of the 76 animals tested positive for chronic wasting disease. The 76 deer constituted the breeding herd on Hall’s farm. He also operated a hunting preserve on the property until 2005. Four deer, two does and two fawns, the only deer remaining in the former preserve, were killed and tested as well. CWD was not detected in those animals. The total number of deer to test positive from this farm from the initial discovery to final depopulation is 82. The CWD infection rate was nearly 80%, the highest ever in a North American captive herd.

The property has undergone cleaning and disinfection as per USDA guidelines. Under an established premise plan, no species of cervids could be brought onto the property for five years, and fences must be maintained to keep wild deer from entering the property so long as the property remained under current ownership. The premise plan expired on May 24, 2011.

Despite the five year premise plan and site decontamination, The WI DNR has concerns over the bioavailability of infectious prions at this site to wild white-tail deer should these fences be removed. Current research indicates that prions can persist in soil for a minimum of 3 years. However, Georgsson et al. (2006) concluded that prions that produced scrapie disease in sheep remained bioavailable and infectious for at least 16 years in natural Icelandic environments, most likely in contaminated soil. Additionally, the authors reported that from 1978-2004, scrapie recurred on 33 sheep farms, of which 9 recurrences occurred 14-21 years after initial culling and subsequent restocking efforts; these findings further emphasize the effect of environmental contamination on sustaining TSE infectivity and that long-term persistence of prions in soils may be substantially greater than previously thought. Evidence of environmental transmission also was documented in a Colorado research facility where mule deer became infected with CWD in two of three paddocks where infected deer carcasses had decomposed on site 1.8 years earlier, and in one of three paddocks where infected deer had last resided 2.2 years earlier (Miller et al. 2004).

Environmental contamination has been identified as a possible cause of recurrence of CWD-infection on elk farms in Canada, when elk were reintroduced one year after depopulation, clean up and disinfection. To date, 8 CWD infected farms remain under CFIA (government of Canada) quarantine indefinitely and will not be allowed to repopulate with cervids until there is additional research on detection of prions in soils and better understanding of the duration of persistence of disease-causing prion post depopulation of CWD-infected cervid farms (Douglas, CFIA, pers. comm.).

Furthermore, the likely transmission of CWD via soil is corroborated by recent studies showing long-term persistence of prions in soil, that prion binds to soil components with high affinity and is not easily removed by water, and that oral prion disease transmission may be enhanced when bound to soil (Johnson et al. 2006, Schramm et al. 2006, Johnson et al. 2007). These findings suggest that soil may harbor more TSE infectivity and contribute more significantly to TSE transmission than previously recognized. These studies highlight the concerns about the risk of transmission via environmental contamination beyond five years and that efforts should be made to prevent freeranging deer from coming into contact with these contaminated facilities.

CHAPTER TWO

OBJECTIVE FOR PROPERTY

Maintain the Perimeter Deer Fence

The primary reason for DNR purchase of the property is to ensure that the deer fence remains intact, preventing wild deer from accessing the prion infected property. The DNR has an ethical and financial responsibility to maintain the fences until the science offers a solution for assessing the risk of remediating the site. The fence will be inspected frequently and repaired as needed.

It is desired to construct a second deer proof fence outside of the existing fence as further insurance for the property. The land immediately outside of the current fence will be cleared of all trees and brush to prepare of installation of the fence and allow vehicle access between the fences. It is hoped that land clearing will be completed in the fall of 2011 with the new fence being constructed as soon as conditions permit in 2012, however, the timing is contingent on funding.

Research Opportunities

The DNR plans to use the Almond Farm as a CWD research facility. Because the question of how long a contaminated site is a risk to deer is of national and international interest, there may be opportunities for research and funding at this facility. One way to potentially assess whether there is a risk to deer from the Almond Farm is to conduct bioassays, either on site or at an alternate location, to monitor for disease transmission. Any proposed research that includes bringing captive cervids onto the property will be thoroughly reviewed by the CWD Research Committee consisting of the Wildlife Health Team, the Wildlife Policy Team, and Department administration as well as external CWD experts prior to permission being granted to ensure that the health of the wild deer herd will not be endangered. The double fencing described above will be critical to minimize the risk of ingress of free-ranging and egress of any experimental captive cervids.

CHAPTER THREE

BIOSECURITY PROTOCOLS

The “Almond Farm” owned by the Wisconsin DNR is a CWD prion contaminated facility, and specific guidelines for apparel and equipment sanitization must be followed to prevent prion contamination outside of the contaminated facility. Sanitization guidelines for equipment and surfaces are based upon recommendations from the American Association of Veterinary Laboratory Diagnosticians: Laboratory Safety and Waste disposal Committee and Pathology Committee 2004 publication, “Best Management Practices for Handling Suspect Biosafety Level 2 Animal Transmissible Spongiform Encephalopathy (TSE) Diagnostic Samples. (Scrapie, Chronic Wasting Disease and Transmissible Mink Encephalopathy) In Animal Health Laboratories” These guidelines are as follows:

General Apparel Guidelines

Facilities should have dedicated PPE (Personal Protective Equipment) that stays on site, and should not be removed under any circumstance. Examples of this are as follows: Boots/overshoes, gloves, eye and ear protection, coveralls, etc.

Anyone entering either facility that chooses to not wear dedicated reusable PPE shall be required to utilize disposable PPE that must be disposed of after each daily use. Examples of acceptable disposable PPE are: Tyvek coveralls, disposable gloves, plastic boot covers, etc.

Any personal footwear not left on site must be sanitized utilizing a 50/50 bleach/water solution*.

Personnel Entry/Exit

Upon entry into contaminated areas, personal footwear should be either removed and replaced by dedicated facility boots, or must be covered with plastic boot covers.

Personal clothing should be covered by putting on disposable Tyvek coveralls to prevent clothing contamination.

If contaminated material will be handled, hands should be covered with latex/nitrile gloves.

Prior to exiting contaminated areas of the facility, all persons must walk through a 50/50* bleach/water solution if boots are worn, or boot covers must be removed and disposed of.

All contaminated disposable apparel must be removed prior to exiting the facility.

Trash receptacles for disposable clothing, gloves, and boot covers should be lined and emptied daily, with liners being tightly sealed and placed directly into closed dumpsters designated for waste disposal in a sanitary landfill.

Equipment Sanitization

All tools, instruments, surfaces, and equipment that have been used in potentially contaminated areas of the facility should be sanitized using a 50/50 bleach/water solution*.

Tools or instruments that come into contact with blood, other bodily fluids, or tissues from potentially positive animals should be soaked in a 50/50 bleach/water solution for 60 minutes to be fully disinfected.

All equipment used on site must be sanitized prior to being transferred to alternate locations (preferably, equipment used on site will be kept on-site).

Equipment that is intended to be moved from the property can only enter on frozen snow covered ground.

Equipment that may be moved between facilities (skid steer, ATV’s, etc.) must be pressure-washed on site prior to movement.

* 50/50 (1:1) Bleach/water solution is a chemically approved and proven method of sanitizing surfaces, sampling/necropsy instruments, and footwear. By using a 50/50 solution, the concentration of chlorine is @20,000 ppm, which is required to neutralize prions to an acceptable level of biosafety. For more information on recommended sanitization procedures, refer to: BEST MANAGEMENT PRACTICES FOR HANDLING SUSPECT BIOSAFETY LEVEL 2 ANIMAL TRANSMISSIBLE SPONGIFORM ENCEPHALOPATHY (TSE) DIAGNOSTIC SAMPLES (SCRAPIE, CHRONIC WASTING DISEAS E AND TRANSMISSIBLE MINK ENCEPHALOPATHY) IN ANIMAL HEALTH LABORATORIES: AAVLD BMP CWD scrapie FINAL 18 Feb 2004.pdf

> > >  The CWD infection rate was nearly 80%, the highest ever in a North American captive herd.


Despite the five year premise plan and site decontamination, The WI DNR has concerns over the bioavailability of infectious prions at this site to wild white-tail deer should these fences be removed. Current research indicates that prions can persist in soil for a minimum of 3 years.


However, Georgsson et al. (2006) concluded that prions that produced scrapie disease in sheep remained bioavailable and infectious for at least 16 years in natural Icelandic environments, most likely in contaminated soil.


Additionally, the authors reported that from 1978-2004, scrapie recurred on 33 sheep farms, of which 9 recurrences occurred 14-21 years after initial culling and subsequent restocking efforts; these findings further emphasize the effect of environmental contamination on sustaining TSE infectivity and that long-term persistence of prions in soils may be substantially greater than previously thought. < < <


SEEMS Wisconsin may have to have a 5 year CWD plan of quarantine and disinfection for the whole state of Wisconsin, and that probably is not near long enough. it may take decades, if Wisconsin can ever be cleaned up at all.

SUBJECT: Public input sought on future of CWO-tainted deer farm


BAD CLAlRE - Neighbors and others interested ill the deer farm formerly known as Buckhorn Flats are invited to a public meeting on the future ofthe property, now owned by the state Department of Natural Resources.


The open house meeting will mil 6-8 p.m. Thursday, July 28, in the auditorium at the Almond- Bancroft School at 1336 Elm Street in Almond, Background on the property, now called the Almond Deer Farm, will be provided, and the public is invited to ask questions and offer input 011 the management of the site,


The first case of CWD, 01' chronic wasting disease, among Wisconsin farm-raised deer was discovered on this property in September 2002. CWD, which affects deer and elk, is a contagious and always fatal brain disease for which there is no cure. The discovery o.f CWD on this property led .to the . depopulation of the entire deer herd on the farm.


In the end, 82 of the deer killed and removed tested positive for CWD. This is an 80 percent infection rate, the highest rate ofCWD infection recorded in North America, and possibly in the world.


The property is located along the east side of3rd Street, about one mile north and west of the Village of Almond in Portage County. The DNR purchased the 80~acre property this past spring for $465,000. There are 25 acres of cropland and 55 acres of woodland. About 65 acres are fenced, the area previously used as a deer farm. The property includes a single-family residence and a storage shed located outside of the fence.


Research indicates prions, proteins associated with the disease, can persist in soil for a minimum of three years and perhaps much longer. Prions that cause scrapie, a CWD-Iike disease in sheep and goats, have remained available and infectious for up to 16 years. DNR officials believe there is all unacceptable risk that CWD prions would infect wild white-tailed deer around this site if the fences would be removed. Since the previous owners were selling the property, and there is no continuing obligation to maintain the fence, wildlife officials concluded the best available option was to acquire the property.


similar if less acute concerns exist for all nine deer farms in Wisconsin that have tested positive for CWD. Because the question of how long a contaminated site is a risk to deer is of national and international 'interest there will be a number of opportunities for research at the Almond farm. Plans include building a second fence, if funding is available, to provide a secondary barrier and further reduce the risk of disease transmission to the wild deer herd. In addition, DNR officials must decide whether to maintain ownership of the house and lot.


The primary reason for DNR purchase ofthe property is to ensure that the deel-,fence remains intact, preventing wild deer from accessing the property and becoming infected. The pNR has an ethical and financial responsibility to maintain the fences until science offers a solution for assessing the risk 01' remediating the site. The fence will be inspected frequently.

*** 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.

Environmental Sources of Scrapie Prions

SNIP...

Some unofficial information from a source on the inside looking out -

Confidential!!!!

As early as 1992-3 there had been long studies conducted on small pastures containing scrapie infected sheep at the sheep research station associated with the Neuropathogenesis Unit in Edinburgh, Scotland. Whether these are documented...I don't know. But personal recounts both heard and recorded in a daily journal indicate that leaving the pastures free and replacing the topsoil completely at least 2 feet of thickness each year for SEVEN years....and then when very clean (proven scrapie free) sheep were placed on these small pastures.... the new sheep also broke out with scrapie and passed it to offspring. I am not sure that TSE contaminated ground could ever be free of the agent!! A very frightening revelation!!!

----------

You can take that with however many grains of salt you wish, and we can debate these issues all day long, but the bottom line, this is not rocket-science, all one has to do is some experiments and case studies. But for the life of me, I don't know what they are waiting on?

Accelerated shedding of prions following damage to the olfactory epithelium

ABSTRACT

In this study we investigated the role of damage to the nasal mucosa in the shedding of prions into nasal fluids as a pathway for prion transmission. Here we demonstrate that prions can replicate to high levels in the olfactory sensory epithelium (OSE) in hamsters and that induction of apoptosis in olfactory receptor neurons (ORNs) in the OSE resulted in sloughing off of the OSE from nasal turbinates into the lumen of the nasal airway. In the absence of nasotoxic treatment olfactory marker protein (OMP), which is specific for ORNs, was not detected in nasal lavages. However, after nasotoxic treatment that leads to apoptosis of ORNs both OMP and prion proteins were present in nasal lavages. The cellular debris that was released from the OSE into the lumen of the nasal airway was positive for both OMP and the disease-specific isoform of the prion protein, PrPSc. Using the real time quaking-induced conversion assay to quantify prions, a 100- to 1,000-fold increase in prion seeding activity was observed in nasal lavages following nasotoxic treatment. Since neurons replicate prions to higher levels than other cell types and ORNs are the most environmentally exposed neurons, we propose that an increase in ORN apoptosis or damage to the nasal mucosa in a host with a pre-existing prion infection of the OSE could lead to a substantial increase in the release of prion infectivity into nasal fluids. This mechanism of prion shedding from the olfactory mucosa could contribute to prion transmission.

Survival and Limited Spread of TSE Infectivity after Burial

Karen Fernie, Allister Smith and Robert A. Somerville The Roslin Institute and R(D)SVS; University of Edinburgh; Roslin, Scotland UK

Scrapie and chronic wasting disease probably spread via environmental routes, and there are also concerns about BSE infection remaining in the environment after carcass burial or waste 3disposal. In two demonstration experiments we are determining survival and migration of TSE infectivity when buried for up to five years, as an uncontained point source or within bovine heads. Firstly boluses of TSE infected mouse brain were buried in lysimeters containing either sandy or clay soil. Migration from the boluses is being assessed from soil cores taken over time. With the exception of a very small amount of infectivity found 25 cm from the bolus in sandy soil after 12 months, no other infectivity has been detected up to three years. Secondly, ten bovine heads were spiked with TSE infected mouse brain and buried in the two soil types. Pairs of heads have been exhumed annually and assessed for infectivity within and around them. After one year and after two years, infectivity was detected in most intracranial samples and in some of the soil samples taken from immediately surrounding the heads. The infectivity assays for the samples in and around the heads exhumed at years three and four are underway. These data show that TSE infectivity can survive burial for long periods but migrates slowly. Risk assessments should take into account the likely long survival rate when infected material has been buried.

Envt.16: Soil Properties as a Factor in CWD Spread in Western Canada

Alsu Kuznetsova,† Tariq Siddique and Judd Aiken

University of Alberta; Edmonton, AB Canada†Presenting author; Email: alsu@ualberta.ca

Soil can serve as a stable reservoir for infectious prion proteins (PrPSc). Soils are diverse and complex, varying in clay, silt, sand and organic components. We have shown that PrPSc binds clay minerals avidly, an interaction that considerably enhances prion infectivity. Conversely quartz sand bound PrPSc less avidly. These studies would suggest that soils with lower clay and higher sand content bind prions less avidly and do not enhance infectivity to the same level as clay-rich soils. We hypothesize that clay content of a soil plays an integral role in the spread of CWD. In this study, we present the soil properties in the western Canada. Soils of the CWD-region generally are similar in texture, clay mineralogy and soil organic matter content. In total these soils can be characterized as clay loamy, montmorillonite (smectite) with 6–10 % organic carbon. The major soils in the CWD-region are Chernozems, present in 60% of total area. These soils have a humic horizon in which organic matter has accumulated (1–17% organic C). Solonetzic soils are also common to Alberta and Saskatchewan. We suggest that the greatest risk of CWD spread in western Canada is restricted to clay loamy, montmorillonite soils with humus horizon. Such soils are predominant in the southern region of Alberta, Saskatchewan and Manitoba, but are less common in northern regions of the provinces.

Envt.28: High Survival Rates of TSE Infectivity Buried in Two Soil Types Allister J. Smith The Roslin Insitute; Roslin, UK Email: allister.smith@roslin.ed.ac.uk Two field experiments nearing completion are investigating the migration and/or persistence of TSE infectivity in the soil environment, either buried within bovine heads or buried without containment. In the first experiment five pairs of bovine heads, spiked with mouse-passaged BSE (301V) macerate, were buried within lysimeters containing either clay or sandy soil. A pair of unspiked bovine heads was also buried to act as controls. Pairs of heads have been exhumed annually during which a corer is used to take soil samples above, surrounding and below the head. Any brain material within the head is recovered during dissection. The soil samples have undergone protein extraction, and the extracts along with the brain material have been assayed for infectivity by bioassay in VM mice. Bioassay results from the first experiment show that for all four years most of the intracranial brain samples have been positive for TSE infectivity in both the clay and sandy soil. There is little change in the survival curves between years 1 and 4 indicating little reduction in the amounts of infectivity over time. There has been very limited infectivity found in samples surrounding the heads buried in the sandy soil, but infectivity has been found in the soil samples surrounding the clay heads and the levels increase slightly from years one to four, presumably as the heads have decomposed. In a parallel experiment a bolus of infectivity (301V) was placed in the centre of two large lysimeters, containing either clay or sandy soil. Over the course of four years, core samples have been taken at eight time points, on the vertical and at 3 distances from the centre. These samples have been assayed for infectivity and to date only one sample from the sandy soil has produced pathological evidence of TSE disease in one mouse. In order to ascertain whether any of the bolus remained at the end of the experiment, we collected a much larger central core (d = 16 cm) and extracted samples for bioassay, concentrating on the core portions that correlated to the original bolus location. The samples from these core portions caused disease in a high proportion of mice (bioassay still in progress), with apparently higher infectivity levels in the clay soil, so far. This result indicates that there has been very little migration of TSE infectivity without containment in either clay or sandy soil and that there has been little reduction in titre with time.

Envt.29: Time-Dependent Decline in PrPTSE Desorption from Soil Particles Christen B. Smith,1,† Clarissa J. Booth,2 Kartik Kumar2 and Joel A. Pedersen1–3 1Environmental Chemistry and Technology Program; 2Molecular and Environmental Toxicology Center; 3Department of Soil Science, University of Wisconsin; Madison, WI USA †Presenting author, Email: cmbell@wisc.edu Environmental routes of transmission are implicated in epizootics of sheep scrapie and chronic wasting disease in deer, elk, and moose. Strong evidence suggests that soil may serve as an environmental reservoir of prions, which can persist in the environment for years. The disease-associated form of the prion protein (PrPTSE) readily attaches to soil particle surfaces. Prior studies reported reduced PrPTSE recovery from experimentally spiked soils after longer contact times, which in some cases has been interpreted as degradation of PrPTSE. Here, we investigate PrPTSE desorption from sterilized and untreated soil particles as a function of protein-soil contact time. Soil particles were sterilized by autoclaving or g-irradiation. Desorption of PrPTSE from whole soils, montmorillonite clay, and quartz sand was analyzed by immunoblotting following 1-, 7-, and 14-day contact times. We found that PrPTSE recovery from both sterile and untreated soil samples declined significantly with contact time suggesting the strengthening of protein-particle interactions over time. Recovery of PrPTSE from whole soils declined to a larger extent than did that from montmorillonite and quartz sand possibly reflecting the contribution of particle-associated natural organic matter to the mechanisms of PrPTSE attachment. The influence of PrPTSE-soil particle attachment on oral disease transmission warrants investigation.

Detection of Protease-Resistant Prion Protein in Water from a CWD-Endemic Area

Chronic wasting disease (CWD) is the only known transmissible spongiform encephalopathy affecting free-ranging wildlife. Experimental and epidemiological data indicate that CWD can be transmitted horizontally and via blood and saliva, although the exact mode of natural transmission remains unknown. Substantial evidence suggests that prions can persist in the environment, implicating it as a potential prion reservoir and transmission vehicle. CWD- positive animals can contribute to environmental prion load via biological materials including saliva, blood, urine and feces, shedding several times their body weight in possibly infectious excreta in their lifetime, as well as through decomposing carcasses. Sensitivity limitations of conventional assays hamper evaluation of environmental prion loads in water. Here we show the ability of serial protein misfolding cyclic amplification (sPMCA) to amplify minute amounts of CWD prions in spiked water samples at a 1:1 x106 , and protease-resistant prions in environmental and municipal-processing water samples from a CWD endemic area. Detection of CWD prions correlated with increased total organic carbon in water runoff from melting winter snowpack. These data suggest prolonged persistence and accumulation of prions in the environment that may promote CWD transmission.

snip...

The data presented here demonstrate that sPMCA can detect low levels of PrPCWD in the environment, corroborate previous biological and experimental data suggesting long term persistence of prions in the environment2,3 and imply that PrPCWD accumulation over time may contribute to transmission of CWD in areas where it has been endemic for decades. This work demonstrates the utility of sPMCA to evaluate other environmental water sources for PrPCWD, including smaller bodies of water such as vernal pools and wallows, where large numbers of cervids congregate and into which prions from infected animals may be shed and concentrated to infectious levels.

The most frightening thing I have read all day is the report of Gambetti's finding of a new strain of sporadic cjd in young people...Dear God, what in the name of all that is holy is that!!! If the US has different strains of scrapie.....why????than the UK...then would the same mechanisms that make different strains of scrapie here make different strains of BSE...if the patterns are different in sheep and mice for scrapie.....could not the BSE be different in the cattle, in the mink, in the humans.......I really think the slides or tissues and everything from these young people with the new strain of sporadic cjd should be put up to be analyzed by many, many experts in cjd........bse.....scrapie Scrape the damn slide and put it into mice.....wait.....chop up the mouse brain and and spinal cord........put into some more mice.....dammit amplify the thing and start the damned research.....This is NOT rocket science...we need to use what we know and get off our butts and move....the whining about how long everything takes.....well it takes a whole lot longer if you whine for a year and then start the research!!! Not sure where I read this but it was a recent press release or something like that: I thought I would fall out of my chair when I read about how there was no worry about infectivity from a histopath slide or tissues because they are preserved in formic acid, or formalin or formaldehyde.....for God's sake........ Ask any pathologist in the UK what the brain tissues in the formalin looks like after a year.......it is a big fat sponge...the agent continues to eat the brain ......you can't make slides anymore because the agent has never stopped........and the old slides that are stained with Hemolysin and Eosin......they get holier and holier and degenerate and continue...what you looked at 6 months ago is not there........Gambetti better be photographing every damned thing he is looking at.....

Okay, you need to know. You don't need to pass it on as nothing will come of it and there is not a damned thing anyone can do about it. Don't even hint at it as it will be denied and laughed at.......... USDA is gonna do as little as possible until there is actually a human case in the USA of the nvcjd........if you want to move this thing along and shake the earth....then we gotta get the victims families to make sure whoever is doing the autopsy is credible, trustworthy, and a saint with the courage of Joan of Arc........I am not kidding!!!! so, unless we get a human death from EXACTLY the same form with EXACTLY the same histopath lesions as seen in the UK nvcjd........forget any action........it is ALL gonna be sporadic!!!

And, if there is a case.......there is gonna be every effort to link it to international travel, international food, etc. etc. etc. etc. etc. They will go so far as to find out if a sex partner had ever traveled to the UK/europe, etc. etc. .... It is gonna be a long, lonely, dangerous twisted journey to the truth. They have all the cards, all the money, and are willing to threaten and carry out those threats....and this may be their biggest downfall...

Thanks as always for your help. (Recently had a very startling revelation from a rather senior person in government here..........knocked me out of my chair........you must keep pushing. If I was a power person....I would be demanding that there be a least a million bovine tested as soon as possible and agressively seeking this disease. The big players are coming out of the woodwork as there is money to be made!!! In short: "FIRE AT WILL"!!! for the very dumb....who's "will"! "Will be the burden to bare if there is any coverup!"

again it was said years ago and it should be taken seriously....BSE will NEVER be found in the US! As for the BSE conference call...I think you did a great service to freedom of information and making some people feign integrity...I find it scary to see that most of the "experts" are employed by the federal government or are supported on the "teat" of federal funds. A scary picture! I hope there is a confidential panel organized by the new government to really investigate this thing.

You need to watch your back........but keep picking at them.......like a buzzard to the bone...you just may get to the truth!!! (You probably have more support than you know. Too many people are afraid to show you or let anyone else know. I have heard a few things myself... you ask the questions that everyone else is too afraid to ask.)

EFSA Journal 2011 The European Response to BSE: A Success Story

snip...

EFSA and the European Centre for Disease Prevention and Control (ECDC) recently delivered a scientific opinion on any possible epidemiological or molecular association between TSEs in animals and humans (EFSA Panel on Biological Hazards (BIOHAZ) and ECDC, 2011). This opinion confirmed Classical BSE prions as the only TSE agents demonstrated to be zoonotic so far but the possibility that a small proportion of human cases so far classified as "sporadic" CJD are of zoonotic origin could not be excluded. Moreover, transmission experiments to non-human primates suggest that some TSE agents in addition to Classical BSE prions in cattle (namely L-type Atypical BSE, Classical BSE in sheep, transmissible mink encephalopathy (TME) and chronic wasting disease (CWD) agents) might have zoonotic potential.

Docket Management Docket: 02N-0276 - Bioterrorism Preparedness; Registration of Food Facilities, Section 305

Comment Number: EC –254

Accepted - Volume 11

Sources: World Trade Atlas What is the level of passenger traffic arriving in the United States from the affected country? Approximately 185,000 direct flights from Greece arrived to US airports in fiscal year 2000. Also, an unknown number of passengers from Greece arrived via indirect flights. Under APHIS-PPQ's agriculture quarantine inspection monitoring, 584 air passengers from Greece were sampled for items of agricultural interest in fiscal year 2000. Of these passengers, 14 carried meat (non-pork) items that could potentially transmit pathogens that cause BSE; most passengers carried from one to two kilograms (kg) of meat, although one passenger in November 1999 carried 23 kg of meat in a suitcase. Florida, Massachusetts, and New York were the reported destinations of these passengers. None of the passengers with meat items reported plans to visit or work on a ranch or farm while in the US.

Greetings list members, i just cannot accept this;

> 23 kg of meat in a suitcase (suitcase bomb...TSS)

> The data do not provide a species of origin code for these

> products, therefore they may not contain any ruminant product.

what kind of statement is this? how stupid do they think we are? it could also very well mean that _all_ of it was ruminant based products !
