Chronic Wasting Disease Detected in Sutton County Deer Breeding Facility, marking the second facility where CWD has been detected in the county

June 27, 2024

Media Contact: TPWD News, Business Hours, 512-389-8030

AUSTIN — Texas Parks and Wildlife Department (TPWD) received confirmation of one case of Chronic Wasting Disease (CWD) in a Sutton County deer breeding facility, marking the second facility where CWD has been detected in the county, located in the Edward Plateau region of Texas.

A two-year-old female white-tailed deer tested positive using postmortem testing conducted to meet CWD surveillance requirements for the facility. Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) initially analyzed the samples, and the National Veterinary Services Laboratory in Iowa confirmed the CWD detection.

CWD has an incubation period that can span years, so the first indication of the disease in a herd is often found through routine surveillance testing rather than observed clinical signs. Early detection and proactive monitoring improve the state’s response time to the detection of CWD and can greatly reduce the risk of further disease spread. TPWD reminds all deer breeders of requirements to report mortalities within seven days of detection and submit CWD test samples within seven days of collection.

CWD is a fatal neurological disease found in certain cervids including deer, elk, moose and other members of the deer family. This slow, progressive disease may not produce visible signs in susceptible species for several years after infection. As the disease process continues, animals with CWD may show changes in behavior and appearance. Clinical signs may include progressive weight loss, stumbling or tremors with a lack of coordination, loss of appetite, teeth grinding, abnormal head posture and/or drooping ears, and excessive thirst, salivation or urination.

In Texas, the disease was first discovered in 2012 in free-ranging mule deer along a remote area of the Hueco Mountains near the Texas-New Mexico border. CWD has since been detected in Texas captive and free-ranging cervids, including white-tailed deer, mule deer, red deer and elk.

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.



In the case of the Brooks County breeding facility, department records indicate that the facility has within the last five years transferred 1,057 deer to 51 deer breeding facilities, five Deer Management Permit (DMP) sites, and 77 release sites located in a total of 67 counties, as well as to three destinations in Mexico.

In the case of the Frio County breeding facility, department records indicate that the facility has "certified herd" status under the TAHC herd certification program and within the last five years has transferred 627 deer to 46 deer breeding facilities, two nursing facilities, two DMP sites, and 29 release sites located in a total of 41 counties.

In the case of the Zavala County breeding facility, department records indicate that within the last five years the facility has transferred 276 deer to three deer breeding facilities, one DMP facility, and 21 release sites located in a total of 14 counties.

In the case of the Kimble County breeding facility, the facility was the source or destination for 282 deer, including deer sent to seven release sites.

In the case of the Cherokee County breeding facility, the facility received 17 deer from four breeding facilities but did not transfer deer to another breeding facility or release site.

The breeding facilities, nursing facilities, DMP facilities, and release sites that have received deer from the positive facilities are directly connected to those facilities and are of epidemiological concern. These facilities are by current rule also prohibited from receiving or transferring deer unless and until epidemiological investigation determines that Movement Qualified (MQ) status can be restored. Deer breeding facilities that received deer from one or more of the directly connected breeding facilities (referred to as "Tier 1" facilities) are indirectly connected to the positive facilities and are of epidemiological concern because they have received exposed deer that were in a trace-out breeding facility.

The recent detections of CWD in breeding facilities located in Brooks, Frio, Zavala, Kimble, and Cherokee counties are part of an ongoing outbreak of CWD in deer breeding facilities.

Since March 29, 2021, CWD has been detected in 15 counties.

In 2023 alone, CWD has been detected in 12 deer breeding facilities located in nine counties.

Prior to 2021, CWD was detected in six deer breeding facilities located in four counties.

In response to the magnitude and the potential severity of this situation, the emergency rules require the ante-mortem testing of test eligible deer prior to transfer from a breeding facility to another breeding facility.

The emergency action is necessary to protect the state's white-tailed deer populations, as well as associated industries.


TAHC 2 does tested positive and additional testing resulted in 3 subsequent CWD detections Edwards County Deer Breeding Facility

Chronic Wasting Disease Detected in Edwards County Deer Breeding Facility

AUSTIN, TX – Texas Parks and Wildlife Department (TPWD) and Texas Animal Health Commission (TAHC) received confirmation of two cases of chronic wasting disease (CWD) in an Edwards County deer breeding facility, marking the first detections in the county.

A pair of two-year-old does tested positive using antemortem testing conducted to meet CWD surveillance requirements for deer. Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) initially analyzed the samples, and the National Veterinary Services Laboratory in Iowa confirmed the CWD detection. Proactive removal of deer penned with the positive deer and additional testing resulted in three subsequent CWD detections.

Terrible news. I hate to keep saying, but I told them so. I keep telling them so.

They better get a handle on the BSE 589.2001 FEED REGULATIONS, and make changes ASAP?

300NG is enough by oral route to transmit Cwd to Cervid.

I started warning about this around 2013 or so…

Abstract

Using a prion amplification assay, we identified prions in tissues from wild pigs (Sus scrofa) living in areas of the United States with variable chronic wasting disease (CWD) epidemiology. Our findings indicate that scavenging swine could play a role in disseminating CWD and could therefore influence its epidemiology, geographic distribution, and interspecies spread.

Chronic wasting disease (CWD) is a prion disease of particular concern because of its uncontrolled contagious spread among various cervid species in North America (https://www.usgs.gov/media/images/distribution-chronic-wasting-disease-north-america-0External Link), its recent discovery in Nordic countries (1), and its increasingly uncertain zoonotic potential (2). CWD is the only animal prion disease affecting captive as well as wild animals. Persistent shedding of prions by CWD-affected animals and resulting environmental contamination is considered a major route of transmission contributing to spread of the disease. Carcasses of CWD-affected animals represent relevant sources of prion infectivity to multiple animal species that can develop disease or act as vectors to spread infection to new locations.

Free-ranging deer are sympatric with multiple animal species, including some that act as predators, scavengers, or both. Experimental transmissions to study the potential for interspecies CWD transmissions have been attempted in raccoons, ferrets, cattle, sheep, and North American rodents (3–7). Potential interspecies CWD transmission has also been addressed using transgenic (Tg) mice expressing prion proteins (PrP) from relevant animal species (8). Although no reports of natural interspecies CWD transmissions have been documented, experimental studies strongly suggest the possibility for interspecies transmission in nature exists (3–7). Inoculation and serial passage studies reveal the potential of CWD prions to adapt to noncervid species, resulting in emergence of novel prion strains with unpredicted features (9–11).

Wild pigs (Sus scrofa), also called feral swine, are an invasive population comprising domestic swine, Eurasian wild boar, and hybrids of the 2 species (12). Wild pig populations have become established in the United States (Appendix Figure 1, panel A), enabled by their high rates of fecundity; omnivorous and opportunistic diet; and widespread, often human-mediated movement (13). Wild pigs scavenge carcasses on the landscape and have an intimate relationship with the soil because of their routine rooting and wallowing behaviors (14). CWD prions have been experimentally transmitted to domestic pigs by intracerebral and oral exposure routes (15), which is relevant because wild pigs coexist with cervids in CWD endemic areas and reportedly prey on fawns and scavenge deer carcasses. Considering the species overlap in many parts of the United States (Appendix Figure 1, panel B), we studied potential interactions between wild pigs and CWD prions.

Snip…

Conclusions

In summary, results from this study showed that wild pigs are exposed to cervid prions, although the pigs seem to display some resistance to infection via natural exposure. Future studies should address the susceptibility of this invasive animal species to the multiple prion strains circulating in the environment. Nonetheless, identification of CWD prions in wild pig tissues indicated the potential for pigs to move prions across the landscape, which may, in turn, influence the epidemiology and geographic spread of CWD.

and Drug Administration's BSE Feed Regulation (21 CFR 589.2000) Singeltary Another Request for Update 2023

The infamous 1997 mad cow feed ban i.e. Food and Drug Administration's BSE Feed Regulation (21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin) from deer and elk is prohibited for use in feed for ruminant animals. With regards to feed for non-ruminant animals, under FDA law, CWD positive deer may not be used for any animal feed or feed ingredients. For elk and deer considered at high risk for CWD, the FDA recommends that these animals do not enter the animal feed system. However, this recommendation is guidance and not a requirement by law.

***>However, this recommendation is guidance and not a requirement by law.

Bottom line, USA is testing so few cows for BSE (<25k tested annually)

BUT, even at those low testing figures, the USA did just confirm another case of BSE just here recently. Feed ban has failed terribly, and CWD is spreading in the USA, at an alarming rate. Recent transmission studies show oral transmission of CWD of Cervid to cattle. Studies also show links of sporadic CJD to BSE, Scrapie, and CWD. It’s a Whole new game of Prion poker now$$$
