Texas 5th Captive Herd Depopulated This Year Due To Positive CWD TSE Prion
Deer herd killed
Fifth ranch in 2026 depopulated by TPWD

LONE STAR OUTDOOR NEWS
A Callahan County white-tailed deer breeding ranch had its deer herd completely wiped out in August after a 13-year-old doe tested positive for chronic wasting disease.
The facility was the fifth ranch that has had its deer herd killed by Texas Parks and Wildlife Department due to positive CWD tests this year. Of the 198 deer killed after the initial positive test, none came back positive for CWD, according to official records.
"Facility received notice July 10, 2026, that a deer) was CWD suspect positive and the post-mortem sample was being sent to (the lab) for confirmation. On July 23, 2026, (the doe) was confirmed CWD positive in the obex and retropharyngeal lymph node tissue," according to the TPWD Disease Management Plan for the facility.
The facility was placed on restricted movement status and given an option for TPWD to kill the herd, which came with an indemnity payment from the USDA, or choose another mitigation route by isolating bucks on a separate facility or breed WD-resistant strains into their herd, which is both time consuming and difficult. The ranch took the option to liquidate the herd, according to TPWD.
USDA's Department of Agriculture Animal and Plant Health Inspection Service was allocated $12 million dollars to reimburse ranchers and deer breeders from the impact of CWD. The organization can allocate up to $3,000 per live deer.
TPWD's Big Game Program Director Kory Gann said although mid-August is not an ideal time to depopulate a herd, it needed to be done before an Aug. 15 deadline with USDA so they could get the ranch owner indemnity money before the fiscal year expired for USDA.
"They gave us a tight deadline for the facility to receive funds by the end of September," Gann said. "We did what we needed to do."
It's a bit of a mystery how a 13-year-old doe suddenly shows up with a positive CWD test in a penned area with many other deer, yet none of the others tested positive. "We are seeing different services bringing these prions into facilities," Gann
said. "Vet services, artificial inseminations, using the same utensils on animals to perform work, it can happen a lot of different ways. We are detecting it earlier and earlier by improving testing methods, but it is concerning how it appears."
This year's five-ranch total comes on the heels of the Kerr Wildlife Management Area depopulating its research facility several years ago when a test, later found to be a possible false positive, was found and the herd was killed.
"TPWD staff are disappointed to abruptly end nearly 50 years of white-tailed deer research that has significantly influenced deer management in Texas and across the country" said John Silovsky, Wildlife Division director in late 2023. "Staff will continue to investigate opportunities to enhance the understanding of this insidious disease in both captive environments and free-ranging populations."
TPWD killed the Kerr WMA herd before the final test results came back from lowa.
Texas Tech University is working on a patent for a live testing method, although it could be years before it is used as a legitimate test for CWD. Currently, the only approved testing has to come from a dead deer.

it will be a blessing to finally get a certified, and validated, Live, CWD TEST, for Cervid, to stop the _necessity_ of killing a cervid to test for CWD.
for all the naysayers that think CWD TSE Prion is a hoax, conspiracy, insurance companies, money grab, or that deer don’t die from CWD, i beg to differ…terry

Texas Kimble County Farm Chronic Wasting Disease CWD TSE Prion Approximate Herd Prevalence 12%
SUMMARY MINUTES OF THE 407th COMMISSION MEETING Texas Animal Health Commission
September 22, 2020
Chronic Wasting Disease (CWD):
A new CWD positive breeding herd was disclosed in February 2020 in Kimble County. This herd depopulation was completed in July 2020. Including the two index positive deer, an additional eight more positive deer were disclosed (approximate herd prevalence 12%). Since July 2015 and prior to this discovery, five positive captive breeder herds have been disclosed and four of those are in Medina County. One herd in Lavaca and three herds in Medina County were depopulated leaving one large herd in Medina County that is managed on a herd plan. A new zone was established in Val Verde County in December 2019 as a result of a positive free-ranging White-tailed Deer (WTD). A second positive WTD was also disclosed in February 2020 in the same area.
SUMMARY MINUTES OF THE 407th COMMISSION MEETING – 9/22/2020
Scrapie: The flock identified in April 2016 remains under quarantine in Hartley County.

APHIS’ voluntary national CWD Herd Certification Plan (HCP) helps States, Tribes, and the cervid industry control CWD in farmed cervids by allowing the interstate movement only from certified herds considered to be low risk.
Currently, 30 States participate in the national CWD HCP: 29 have Approved Status and 1 has Provisional Approved Status. States that meet the CWD HCP requirements have Approved Status and States that do not meet CWD HCP program requirements but have developed a work plan and time frame with APHIS to complete those requirements have Provisional Approved Status.
In FY 2015, the program tested approximately 20,000 farmed cervids for CWD and identified eight new CWD positive farmed white-tailed deer herds – one in Utah, one in Pennsylvania, two in Ohio, two in Wisconsin, and two in Texas.
APHIS depopulated five of these herds (Pennsylvania, Utah, and one each in Wisconsin, Texas, and Ohio). Six elk herds in Colorado, four elk herds in Nebraska, one white-tailed deer herd in Wisconsin and one white-tailed deer herd in Texas remained in quarantine at the end of FY 2015.
APHIS also provided indemnity for and was the lead agency for the depopulation and disposal of four large CWD infected farmed cervid herds in Pennsylvania, Ohio, Utah, and Texas. In cooperation with the National Agricultural Statistics Service, APHIS conducted the first national study of the U.S. farmed-cervid industry in FY 2015. The study provides baseline industry statistics, a description of production practices and challenges, producer-reported disease occurrences, and an overview of health management and biosecurity practices.

2015 Explanatory Notes Animal and Plant Health Inspection Service
In FY 2013, the program tested approximately 18,100 farmed cervids for CWD, a fatal, degenerative disease that affects the central nervous system and lymphoid system of cervids. Through this routine surveillance, no new CWD cases were reported in farmed cervids in FY 2013. The last CWD positive herd was reported in FY 2012 in an Iowa white tail deer herd. Twelve positive herds remain (seven elk herds in Colorado, three elk herds in Nebraska, one white tail deer herd in Iowa, and one red deer herd in Minnesota).

2014 Explanatory Notes Animal and Plant Health Inspection Service
In 2007, the cervid industry in the United States included 5,600 deer farms and 1,900 elk farms with an economic value of $894 million that supported nearly 30,000 jobs.
APHIS’ main cervid activities are testing approximately 15,000 captive cervids for tuberculosis each year and supporting the chronic wasting disease (CWD) herd certification program (HCP). The joint tuberculosis (TB) and brucellosis proposed rule will represent significant changes to TB activities in captive cervids when implemented; it proposes to bring cervids into the regulatory program for brucellosis, as requested by stakeholders. As a result, surveillance will be enhanced and the number of captive cervids that are tested for TB annually is expected to increase. In 2014, APHIS will implement a survey to evaluate the effectiveness and impact of new APHIS regulations on the industry. Additionally, approval for a new diagnostic test for TB in captive cervids is expected to occur by FY 2013. The CWD HCP allows participating States to enroll herd owners

to meet minimum Federal standards to achieve and maintain a herd certification status. APHIS approves State applications for the national voluntary CWD herd certification program, conducts periodic reviews to ensure compliance, and supports confirmatory testing of presumptive CWD cases.
snip…
Without continued program funding, there would be a reduced preparedness, surveillance, and response to equine/cervid health issues that could increase the likelihood of disease spread resulting in larger and more serious disease outbreaks, lack of national standards leading to a patchwork of State level requirements which diminish interstate commerce, and loss in international credibility regarding U.S. animal health status.
Approximately 59 percent of the Equine and Cervid Health funding will be used for salaries and benefits, less than 1 percent for cooperative agreements and programmatic contracts, and the remaining supports normal operating costs such as travel, supplies, rent and utilities.
Reduce lower priority program activities (-$1.295 million) APHIS will reduce lower priority equine and cervid program activities in 2014, including eliminating Federal contributions for addressing CWD.
CWD is a degenerative neurological illness affecting elk and deer (cervids) in North America.
***> APHIS has determined that continued efforts to manage CWD are not practical and therefore considers this to be a low priority for the Agency.
***> On August 13, 2012, the rule that established uniform standards for a voluntary Federal-State cooperative CWD HCP and interstate movement requirements became effective. Implementation of the interstate movement of cervids was implemented in December 2012.
***> Many States have herd certification programs in place, and the incidence of CWD detections in farmed cervids is decreasing.
***> With the regulatory framework in place, continued APHIS activity, while useful, is no longer essential.
Stakeholders can continue to carry on program activities. The success of the voluntary HCP is based upon cooperation and shared responsibility among the Federal government and State and local interests. However, since these are local or regional disease spread issues, State and local governments are better positioned to take a more active role and to better anticipate and plan for local or regional needs. APHIS will continue to conduct higher priority equine and cervid health activities and address concerns when identified. APHIS will reassign staff years to other Equine and Cervid Health activities as practical and reduce the overall staff years by eliminating the positions when vacancies arise. Reduction in Agency-level operating expenses (-$66,000) A reduction of $66,000 is requested for this line item related to Agency-level cost savings measures and operating efficiencies. Please refer to second paragraph on page 18-18.

=====
i remember…
***> The occurrence of CWD must be viewed against the contest of the locations in which it occurred. It was an incidental and unwelcome complication of the respective wildlife research programmes. Despite its subsequent recognition as a new disease of cervids, therefore justifying direct investigation, no specific research funding was forthcoming. The USDA viewed it as a wildlife problem and consequently not their province!” page 26.

***> TRUCKING CWD TSE PRION
“CWD spreads among wild populations at a relatively slow rate, limited by the natural home range and dispersed nature of wild animals.”
***> NOW HOLD YOUR HORSES, Chronic Wasting Disease CWD of Cervid can spread rather swiftly, traveling around 50 MPH, from the back of truck and trailer, and Here in Texas, we call it ‘Trucking CWD’…
Preventive Veterinary Medicine Volume 234, January 2025, 106385
Use of biosecurity practices to prevent chronic wasting disease in Minnesota cervid herds
Vehicles or trailers that entered the farm were used to transport other live cervids, cervid carcasses, or cervid body parts in past 3 years in 64.3 % (95 % CI 46.3–82.3) of larger elk/reindeer herds compared to 13.6 % (95 % CI 4.7–22.4) of smaller deer herds.
Snip…
Identifying the exact pathway of initial CWD transmission to cervid herds is often not possible, in part due to many potential pathways of transmission for the infection, including both direct and indirect contact with infected farmed or wild cervids (Kincheloe et al., 2021). That study identified that transmissions from infected farmed cervids may occur from direct contact with the movement of cervids from one herd to another and from indirect contact with the sharing of equipment, vehicles, clothing, reproductive equipment, and potentially through semen or embryos.
https://www.sciencedirect.com/science/article/abs/pii/S016758772400271X
“Chronic Wasting Disease (CWD) is a fatal neurological disease and can devastate deer populations by silently spreading through direct animal contact and contaminated environments. Without close monitoring, illegal movement of captive deer increases the risk of introducing CWD to areas it is not known to exist, potentially leading to widespread outbreaks which will impact more than just the health of Texas deer.”

CWD, Seeing is believing Videos Part 1, Part 2
The below video series is provided by the Mississippi State Deer Lab with many contributing Partners. Click image to find all videos in the series.
Seeing is Believing is a two part documentary film that hopes to increase awareness about chornic wasting disease (CWD). Although most hunters and landowners may never witness a clinically ill animal in an area with high CWD prevalence, the documentary demonstrates how CWD is certainly present, explains why it is a major concern, and how stakeholders are key to managing the disease. Colorado Parks and Wildlife (CPW) developed these films in partnership with the Wyoming Game and Fish Department, Chronic Wasting Disease Alliance, Colorado Department of Agriculture, Animal and Plant Health Inspection Service, and multiple private conservation organizations.

''Free Ranging Deer, Dr. Deyoung looked at Genetics of this free ranging deer and what he found was, that the genetics on this deer were more similar to captive deer, than the free ranging population, but he did not see a significant connection to any one captive facility that he analyzed, so we believe, Ahhhhhh, this animal had some captive ahhh, whatnot.''

''Free Ranging Deer, Dr. Deyoung looked at Genetics of this free ranging deer and what he found was, that the genetics on this deer were more similar to captive deer, than the free ranging population, but he did not see a significant connection to any one captive facility that he analyzed, so we believe, Ahhhhhh, this animal had some captive ahhh, whatnot.''

***> 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!!!

Chronic Wasting Disease CWD TSE Prion
THE CWD TSE Prion aka mad cow type disease is not your normal pathogen.
The TSE prion disease survives ashing to 600 degrees celsius, that’s around 1112 degrees farenheit.
You cannot cook the TSE prion disease out of meat. In fact new data now shows that exposure to high temperatures used to cook the meat increased the availability of prions for in vitro amplification.
you can take the ash and mix it with saline and inject that ash into a mouse, and the mouse will go down with TSE.
Prion Infected Meat-and-Bone Meal Is Still Infectious after Biodiesel Production as well.
the TSE prion agent also survives Simulated Wastewater Treatment Processes.
IN fact, you should also know that the TSE Prion agent will survive in the environment for years, if not decades.
you can bury it and it will not go away.
The TSE agent is capable of infected your water table i.e. Detection of protease-resistant cervid prion protein in water from a CWD-endemic area.
it’s not your ordinary pathogen you can just cook it out and be done
and so it seems…2026
CWD, So, this is what we leave our children and grandchildren?

Detection of prions in soils contaminated by multiple routes
Results: We are able to detect prion seeding activity at multiple types of environmental hotspots, including carcass sites, contaminated captive facilities, and scrapes (i.e. urine and saliva). Differences in relative prion concentration vary depending on the nature and source of the contamination. Additionally, we have determined that prion seeding activity is retained for at least fifteen years at a contaminated site following attempted remediation.
Conclusions: Detection of prions in the environment is of the utmost importance for controlling chronic wasting disease spread. Here, we have demonstrated a viable method for detection of prions in complex environmental matrices. However, it is quite likely that this method underestimates the total infectious prion load in a contaminated sample, due to incomplete recovery of infectious prions. Further refinements are necessary for accurate quantification of prions in such samples, and to account for the intrinsic heterogeneities found in the broader environment.

Chronic wasting disease (CWD) prion detection in environmental and biological samples from a taxidermy site and nursing facility, and instruments used in surveillance activities
Available online 9 April 2025
Highlights
• CWD prions were identified in a taxidermy and deer nursing facility.
• Contaminated samples included waters, soils, dermestid beetles, domestic flies and a dumpster.
• Surgical instruments used to collect deer samples can get contaminated with CWD prions.
• Some of the infectious particles are readily released from surgical instruments when washed.
• Our results suggest that taxidermy practices actively contribute in the spreading of CWD.

In summary, the information provided in this report demonstrate how anthropogenic activities, specifically taxidermy practices, animal processing, and rehabilitation of CWD susceptible species, may facilitate CWD transmission through the environmental dissemination of CWD prions. This study, along with future research efforts characterizing the overall level of infectivity, provides relevant information on managing CWD and to control its rapid geographic expansion. …

Chronic wasting disease detection in environmental and biological samples from a taxidermy site
Results: The PMCA analysis demonstrated CWD seeding activity in some of the components of this facility, including insects involved in head processing, soils, and a trash dumpster.
Conclusions: Different areas of this property were used for various taxidermy procedures. We were able to detect the presence of prions in
i) soils that were in contact with the heads of dead animals, ii) insects involved in the cleaning of skulls, and iii) an empty dumpster where animal carcasses were previously placed.
This is the first report demonstrating that swabbing is a helpful method to screen for prion infectivity on surfaces potentially contaminated with CWD. These findings are relevant as this swabbing and amplification strategy may be used to evaluate the disease status of other free-ranging and captive settings where there is a concern for CWD transmissions, such as at feeders and water troughs with CWD-exposed properties. This approach could have substantial implications for free-ranging cervid surveillance as well as in epidemiological investigations of CWD.

Artificial mineral sites that pre-date endemic chronic wasting disease become prion hotspots
The Ames Research and Educational Center property, centrally located within the CWD zone of southwest Tennessee, contains 49 historical mineral supplementation sites that were decommissioned in 2012. Here, we demonstrate that 32 of the 49 (65%) mineral sites within Ames established prior to the regional CWD outbreak, serve as foci of environmental PrPCWD contamination. Detection of PrPCWD in soils from these artificial mineral sites was dependent on site-specific management efforts. Soil physical properties were very similar across sites and no correlation between PrPCWD detection and soil physical properties was found. The detection of PrPCWD in soils at attractant sites within an endemic CWD zone significantly advances our understanding of environmental PrPCWD accumulation dynamics, providing valuable information for advancing adaptive CWD management approaches.

Conclusions: These studies demonstrate: (a) CWD prion excretion occurs throughout infection; (2) PRNP genotype (GG≫GS/NT) influences the excreta shedding; and (3) detection sensitivity in excreta can vary with different RT-QuIC protocols. These results provide a more complete perspective of prion shedding in deer during the course of CWD infection.

Cases of CWD in Minnesota have risen considerably over the last few years, raising wildlife, environmental, and public health concerns. Infectious prions, such as those causing CWD, enter the environment through bodily fluids or decomposing carcasses of infected individuals and can persist for at least fifteen years in soil and water. Previous studies have shown strong prion sorption to various mineral particles in soils. Through field observation and laboratory experimentation, we observed that prions readily partition to the particulate fraction of environmental waters, suggesting that hydrological transport of prions is likely sediment-facilitated. To effectively contain the spread of CWD through the environment, it is imperative to predict prion transport times and pathways in the context of specific landscape and watershed conditions. Our purpose is to characterize the hydrological transport of prions through watersheds at multiple scales. Through spatial analysis, we mapped surface flow pathways from CWD hotspots in Minnesota to identify how they overlap with major rivers and regions of high soil erosion. Based on in-stream measurements and sediment characterization, we used empirical equations to predict sediment mobilization conditions and transport rates in CWD-contaminated regions with diverse flow regimes. In order to model subsurface prion transport, we began conducting flow-through column experiments testing various flow rates and soil matrices.

Chronic wasting disease affects deer, elk and similar animals in the United States and a few other countries.
The disease hasn't been shown to infect people.
However, it might be a risk to people if they have contact with or eat meat from animals infected with CWD.
we know now from laboratory scientific, transmission studies, CWD, TSE, Prion, will transmit, by oral routes to, Cattle, Pigs; Sheep, Cervid, and Primates. i can still remember, from early BSE days, very frightening stuff.

KEY POINTS
Chronic wasting disease affects deer, elk and similar animals in the United States and a few other countries.
The disease hasn't been shown to infect people.
However, it might be a risk to people if they have contact with or eat meat from animals infected with CWD.

Detection of Chronic Wasting Disease Prions in Raw, Processed, and Cooked Elk Meat, Texas, USA
Snip…
Of note, our data show that exposure to high temperatures used to cook the meat increased the availability of prions for in vitro amplification. Considering the potential implications in food safety and public health, we believe that the findings described in this study warrant further research. Our results suggest that although the elk meat used in this study resisted different manipulations involved in subsequent consumption by humans, their zoonotic potential was limited. Nevertheless, even though no cases of CWD transmission to human have been reported, the potential for human infection is still unclear and continued monitoring for zoonotic potential is warranted.

Detection of chronic wasting disease prions in processed meats
Results: Our results show positive prion detection in all the samples analyzed using deer and elk substrates. Surprisingly, cooked meats displayed increased seeding activities. This data suggests that CWD-prions are available to people even after meats are processed and cooked.
Conclusions: These results suggest CWD prions are accessible to humans through meats, even after processing and cooking. Considering the fact that these samples were collected from already processed specimens, the availability of CWD prions to humans is probably underestimated.

DETECTION OF CHRONIC WASTING DISEASE PRIONS IN PROCESSED MEATS.
In this study, we analyzed different processed meats derived from a pre-clinical, CWD-positive free-ranging elk. Products tested included filets, sausages, boneless steaks, burgers, ham steaks, seasoned chili meats, and spiced meats. CWD-prion presence in these products were assessed by PMCA using deer and elk substrates. Our results show positive prion detection in all products. To confirm the resilience of CWD-prions to traditional cooking methods, we grilled and boiled the meat products and evaluated them for any remnant PMCA seeding activity. Results confirmed the presence of CWD-prions in these meat products suggesting that infectious particles may still be available to people even after cooking. Our results strongly suggest ongoing human exposure to CWD-prions and raise significant concerns of zoonotic transmission through ingestion of CWD contaminated meat products.

Transmission of prion infectivity from CWD-infected macaque tissues to rodent models demonstrates the zoonotic potential of chronic wasting disease.
Further passage to cervidized mice revealed transmission with a 100% attack rate.
Our findings demonstrate that macaques, considered the best model for the zoonotic potential of prions, were infected upon CWD challenge, including the oral one.
The disease manifested as atypical in macaques and initial transgenic mouse transmissions, but with infectivity present at all times, as unveiled in the bank vole model with an unusual tissue tropism.

Transmission of the chronic wasting disease agent from elk to cattle after oronasal exposure
Justin Greenlee, Jifeng Bian, Zoe Lambert, Alexis Frese, and Eric Cassmann Virus and Prion Research Unit, National Animal Disease Center, USDA-ARS, Ames, IA, USA
Aims: The purpose of this study was to determine the susceptibility of cattle to chronic wasting disease agent from elk.
Materials and Methods: Initial studies were conducted in bovinized mice using inoculum derived from elk with various genotypes at codon 132 (MM, LM, LL). Based upon attack rates, inoculum (10% w/v brain homogenate) from an LM132 elk was selected for transmission studies in cattle. At approximately 2 weeks of age, one wild type steer (EE211) and one steer with the E211K polymorphism (EK211) were fed 1 mL of brain homogenate in a quart of milk replacer while another 1 mL was instilled intranasally. The cattle were examined daily for clinical signs for the duration of the experiment. One steer is still under observation at 71 months post-inoculation (mpi).
Results: Inoculum derived from MM132 elk resulted in similar attack rates and incubation periods in mice expressing wild type or K211 bovine PRNP, 35% at 531 days post inoculation (dpi) and 27% at 448 dpi, respectively. Inoculum from LM132 elk had a slightly higher attack rates in mice: 45% (693 dpi) in wild type cattle PRNP and 33% (468) in K211 mice. Inoculum from LL132 elk resulted in the highest attack rate in wild type bovinized mice (53% at 625 dpi), but no K211 mice were affected at >700 days. At approximately 70 mpi, the EK211 genotype steer developed clinical signs suggestive of prion disease, depression, low head carriage, hypersalivation, and ataxia, and was necropsied. Enzyme immunoassay (IDEXX) was positive in brainstem (OD=4.00, but non-detect in retropharyngeal lymph nodes and palatine tonsil. Immunoreactivity was largely limited to the brainstem, midbrain, and cervical spinal cord with a pattern that was primarily glia-associated.
“Conclusions: Cattle with the E211K polymorphism are susceptible to the CWD agent after oronasal exposure of 0.2 g of infectious material.”
Strain characterization of chronic wasting disease in bovine-PrP transgenic mice
Conclusions: Altogether, these results exhibit the diversity of CWD strains present in the panel of CWD isolates and the ability of at least some CWD isolates to infect bovine species. Cattle being one of the most important farming species, this ability represents a potential threat to both animal and human health, and consequently deserves further study.

Preliminary Outbreak Assessment
Chronic wasting disease prions in cervids and wild pigs in North America
26 January 2026
Disease report
Chronic wasting disease (CWD) is a fatal neurodegenerative disease of cervids, such as deer, elk, moose and reindeer. It is caused by prions – infectious proteins that cause normal cellular prion proteins to misfold (CIDRAP, 2025). The disease is widespread in captive and free-ranging cervids in North America (Figure 1). For the first time, CWD prions have also been detected in the tissues of wild pigs (Sus scrofa) caught in CWD-affected areas of the USA (Soto et al. 2025). This discovery emerged from a study designed to investigate potential interactions between wild pigs and CWD prions, as wild pigs often coexist with cervids, which can shed prions into the environment. The following assessment discusses the epidemiology of CWD in North America and the detection of CWD prions in wild pigs. It also considers the potential implications for Great Britain.
Conclusion
CWD has continued to spread among captive and free-ranging cervids in North America since it was first detected in the 1960s. The finding of CWD prions in wild pigs in the USA suggests they could contribute towards transmission of the disease, influencing its epidemiology, geographic distribution and interspecies spread. However, further research is needed to confirm this. CWD has never been reported in Great Britain and the current risk of CWD prions being introduced into Great Britain’s wild pig or cervid population ranges from very low to negligible.
Readers are reminded to be vigilant for signs of CWD. Information on how to spot the disease can be found here. Suspected cases must be reported immediately to the Defra Rural Services Helpline on 03000 200 301. In Wales, call 0300 303 8268. In Scotland, contact your local Field Services Office. Failure to do so is an offence. We will continue to monitor the situation.

Chronic Wasting Disease CWD vs Scrapie TSE Prion
https://www.ars.usda.gov/research/publications/publication/?seqNo115=410511
Detection of infectivity in orally inoculated pigs using mouse bioassay raises the possibility that naturally exposed pigs could act as a reservoir of CWD infectivity. Currently, swine rations in the U.S. could contain animal derived components including materials from deer or elk. In addition, feral swine could be exposed to infected carcasses in areas where CWD is present in wildlife populations. The current feed ban in the U.S. is based exclusively on keeping tissues from TSE infected cattle from entering animal feeds. These results indicating the susceptibility of pigs to CWD, coupled with the limitations of the current feed ban, indicates that a revision of the feed ban may be necessary to protect swine production and potentially human health.

Title: Differentiation of scrapie from chronic wasting disease in white-tailed deer
Accomplishments
1. 01 Determined that white-tailed deer (WTD) infected with scrapie from sheep can transmit the disease to other deer under conditions mimicking natural exposure. It has long been suggested that prion disease in deer (chronic wasting disease (CWD)) was caused by the prion agent from sheep. The prion disease that affects sheep, scrapie, has been recognized for hundreds of years. However, chronic wasting disease, a similar disease found in WTD, has only been recognized since the 1960s. ARS researchers in Ames, Iowa, showed that white-tailed deer sick with scrapie from sheep can infect other deer under conditions mimicking natural exposure. Furthermore, this work shows that CWD is difficult to differentiate from WTD infected with scrapie. WTD scrapie prions accumulate in the lymphoreticular system in a manner similar to CWD, meaning that environmental contamination may occur through feces, saliva, and other body fluids of scrapie affected WTD as has been shown for CWD. The presence of WTD infected with scrapie could confound mitigation efforts for chronic wasting disease. This information informs regulatory officials, the farmed cervid industry, and officials tasked with protecting animal health such as state Departments of Agriculture, Natural Resources, or Parks and Wildlife with regard to a disease similar to CWD but arising from sheep scrapie that could be present in WTD that have contact with scrapie affected sheep and/or goats.

ARS researchers in Ames, Iowa, showed that white-tailed deer sick with scrapie from sheep can infect other deer under conditions mimicking natural exposure. Furthermore, this work shows that CWD is difficult to differentiate from WTD infected with scrapie. WTD scrapie prions accumulate in the lymphoreticular system in a manner similar to CWD, meaning that environmental contamination may occur through feces, saliva, and other body fluids of scrapie affected WTD as has been shown for CWD. The presence of WTD infected with scrapie could confound mitigation efforts for chronic wasting disease. This information informs regulatory officials, the farmed cervid industry, and officials tasked with protecting animal health such as state Departments of Agriculture, Natural Resources, or Parks and Wildlife with regard to a disease similar to CWD but arising from sheep scrapie that could be present in WTD that have contact with scrapie affected sheep and/or goats.
