Big CWD press release coming

[trophy8]

You mean how they're coincidentally geographically located all around the breeding facilities?

See the post below yours. CWD didn’t just show up in a breeder pen. Nor did those deer just appear in a pen. God created it. It is naturally occurring. I just want the breeder haters to use common sense instead of reacting based on emotion and self interest(not aimed at any one person)

And breeder operations are tested at a far high percentage compared to free range. Kinda like Covid. Run more tests. Find more positives.

This map from the link Flounder posted is interested. Especially the amount of places it’s found free range.

Something I find interesting is there are 2 epicenters in that map. One in the US and one in Canada. Are breeders sending deer from Colorado to Saskatchewan and vice versa on a regular basis?

Logically there is only two explanations that would make sense; CWD has been around forever and we have only recently been able to test for it and find it or it started in a pen in one of those places and the transfer of one to the other caused it.

I’d lean towards herd migrations spreading it. But I ain’t no scientist!

The new Kimble county ones are concerning to me and makes me wonder what they did with that facility. They are from facility number 6 which is where it was originally detected in Kimble county February of 2020. My understanding was the facility was depopulated. So, they either repopulated or never depopulated. If they did depopulate, why would you repopulate it so soon? TPWD continues to baffle me with their decisions.

Or it’s still in the ground. Curious on how long it stays alive

I’ve heard and read from 2 years to thousands of years... huge difference there. I’m not a scientist either haha

They are pretty sure it stays in the ground for a prolonged period (time they really don't know). That's why I am baffled that they would repopulate that ranch so soon. I would think a minimum of 5 years before repopulating would be more sensible. Maybe I answered my own question, sensible and TPWD often are mutually exclusive.

Voluntary Chronic Wasting Disease Herd Certification Program Annual Update, FY2020

Last Modified: Feb 9, 2021

Animal and Plant Health Inspection Service (APHIS) Veterinary Services

Annual Update from the Cervid Health Team

Voluntary Chronic Wasting Disease Herd Certification Program (HCP)

The APHIS National CWD Herd Certification Program (HCP) was implemented in 2014. It is a voluntary Federal-State-industry cooperative program administered by APHIS and implemented by participating States. The program provides uniform national herd certification standards that minimize the risk of spreading CWD in farmed cervid populations. Participating States and herd owners must comply with requirements for animal identification, fencing, recordkeeping, inspections/inventories, as well as animal mortality testing and response to any CWD-exposed, suspect, and positive herds. APHIS monitors the Approved State HCPs to ensure consistency with Federal standards through annual reporting by the States.

With each year of successful surveillance, herds participating in the HCP will advance in status until reaching five years with no evidence of CWD, at which time herds are certified as being low risk for CWD. Only farmed cervids from enrolled herds certified as low risk for CWD may move interstate. FY 2020 marks the eighth year that Approved States have submitted their CWD HCP annual reports to APHIS.

The current Cervid Health Program staff officers are as follows: Dr. Mark Lyons, Dr. Jennifer Siembieda, and Dr. Tracy Nichols

Voluntary Herd Certification Participation Summary

Currently, 28 States participate in the voluntary CWD Herd Certification Program encompassing 2,145 enrolled herds, of which, 1,723 had the certified status in the program.

1,616 enrolled deer herds, of which, 1,297 were certified

371 enrolled elk herds, of which, 328 were certified

147 enrolled mixed species herds, of which, 98 were certified

National CWD Tracking Map

https://tpwd.texas.gov/huntwild/wild/diseases/cwd/tracking/

“Regarding the current situation involving CWD in permitted deer breeding facilities, TPWD records indicate that within the last five years, the seven CWD-positive facilities transferred a total of 2,530 deer to 270 locations in 102 counties and eight locations in Mexico (the destinations included 139 deer breeding facilities, 118 release sites, five Deer Management Permit sites, and three nursing facilities).'' ...

It is apparent that prior to the recent emergency rules, the CWD detection rules were ineffective at detecting CWD earlier in the deer breeding facilities where it was eventually discovered and had been present for some time; this creates additional concern regarding adequate mitigation of the risk of transferring CWD-positive breeder deer to release sites where released breeder deer come into contact with free-ranging deer...

Texas Chronic Wasting Disease CWD TSE Prion Confirmed Positive Jumps By 91 Total To Date 361 Cases

[flounder9]

I’ve heard and read from 2 years to thousands of years... huge difference there. I’m not a scientist either haha

TRANSMISSIBLE SPONGIFORM ENCEPHALOPATHY TSE PRION MAD COW TYPE DISEASE

THE 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.

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 with.

***> that’s what’s so worrisome about Iatrogenic mode of transmission, a simple autoclave will not kill this TSE prion agent.

Stereotactic multicontact electrodes used to probe the cerebral cortex of a middle aged woman with progressive dementia were previously implicated in the accidental transmission of Creutzfeldt-Jakob disease (CJD) to two younger patients. The diagnoses of CJD have been confirmed for all three cases. More than two years after their last use in humans, after three cleanings and repeated sterilisation in ethanol and formaldehyde vapour, the electrodes were implanted in the cortex of a chimpanzee. Eighteen months later the animal became ill with CJD. This finding serves to re-emphasise the potential danger posed by reuse of instruments contaminated with the agents of spongiform encephalopathies, even after scrupulous attempts to clean them.

Should Property Evaluations Contain Scrapie, CWD, TSE PRION Environmental Contamination of the land?

***> 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!!!

Scrapie Agent (Strain 263K) Can Transmit Disease via the Oral Route after Persistence in Soil over Years

Published: May 9, 2007

snip...

Our results showed that 263K scrapie agent can persist in soil at least over 29 months. Strikingly, not only the contaminated soil itself retained high levels of infectivity, as evidenced by oral administration to Syrian hamsters, but also feeding of aqueous soil extracts was able to induce disease in the reporter animals. We could also demonstrate that PrPSc in soil, extracted after 21 months, provides a catalytically active seed in the protein misfolding cyclic amplification (PMCA) reaction. PMCA opens therefore a perspective for considerably improving the detectability of prions in soil samples from the field.

Rapid recontamination of a farm building occurs after attempted prion removal

Kevin Christopher Gough BSc (Hons), PhD Claire Alison Baker BSc (Hons) Steve Hawkins MIBiol Hugh Simmons BVSc, MRCVS, MBA, MA Timm Konold DrMedVet, PhD, MRCVS … See all authors

Abstract

The transmissible spongiform encephalopathy scrapie of sheep/goats and chronic wasting disease of cervids are associated with environmental reservoirs of infectivity. Preventing environmental prions acting as a source of infectivity to healthy animals is of major concern to farms that have had outbreaks of scrapie and also to the health management of wild and farmed cervids. Here, an efficient scrapie decontamination protocol was applied to a farm with high levels of environmental contamination with the scrapie agent. Post‐decontamination, no prion material was detected within samples taken from the farm buildings as determined using a sensitive in vitro replication assay (sPMCA). A bioassay consisting of 25 newborn lambs of highly susceptible prion protein genotype VRQ/VRQ introduced into this decontaminated barn was carried out in addition to sampling and analysis of dust samples that were collected during the bioassay. Twenty‐four of the animals examined by immunohistochemical analysis of lymphatic tissues were scrapie‐positive during the bioassay, samples of dust collected within the barn were positive by month 3. The data illustrates the difficulty in decontaminating farm buildings from scrapie, and demonstrates the likely contribution of farm dust to the recontamination of these environments to levels that are capable of causing disease.

This study clearly demonstrates the difficulty in removing scrapie infectivity from the farm environment. Practical and effective prion decontamination methods are still urgently required for decontamination of scrapie infectivity from farms that have had cases of scrapie and this is particularly relevant for scrapiepositive goatherds, which currently have limited genetic resistance to scrapie within commercial breeds.24 This is very likely to have parallels with control efforts for CWD in cervids.

Classical scrapie is an environmentally transmissible prion disease of sheep and goats. Prions can persist and remain potentially infectious in the environment for many years and thus pose a risk of infecting animals after re-stocking. In vitro studies using serial protein misfolding cyclic amplification (sPMCA) have suggested that objects on a scrapie-affected sheep farm could contribute to disease transmission. This in vivo study aimed to determine the role of field furniture (water troughs, feeding troughs, fencing, and other objects that sheep may rub against) used by a scrapie-infected sheep flock as a vector for disease transmission to scrapie-free lambs with the prion protein genotype VRQ/VRQ, which is associated with high susceptibility to classical scrapie. When the field furniture was placed in clean accommodation, sheep became infected when exposed to either a water trough (four out of five) or to objects used for rubbing (four out of seven). This field furniture had been used by the scrapie-infected flock 8 weeks earlier and had previously been shown to harbor scrapie prions by sPMCA. Sheep also became infected (20 out of 23) through exposure to contaminated field furniture placed within pasture not used by scrapie-infected sheep for 40 months, even though swabs from this furniture tested negative by PMCA. This infection rate decreased (1 out of 12) on the same paddock after replacement with clean field furniture. Twelve grazing sheep exposed to field furniture not in contact with scrapie-infected sheep for 18 months remained scrapie free. The findings of this study highlight the role of field furniture used by scrapie-infected sheep to act as a reservoir for disease re-introduction although infectivity declines considerably if the field furniture has not been in contact with scrapie-infected sheep for several months. PMCA may not be as sensitive as VRQ/VRQ sheep to test for environmental contamination.

Discussion

SNIP...

In conclusion, the results in the current study indicate that removal of furniture that had been in contact with scrapie-infected animals should be recommended, particularly since cleaning and decontamination may not effectively remove scrapie infectivity (31), even though infectivity declines considerably if the pasture and the field furniture have not been in contact with scrapie-infected sheep for several months. As sPMCA failed to detect PrPSc in furniture that was subjected to weathering, even though exposure led to infection in sheep, this method may not always be reliable in predicting the risk of scrapie infection through environmental contamination.

These results suggest that the VRQ/VRQ sheep model may be more sensitive than sPMCA for the detection of environmentally associated scrapie, and suggest that extremely low levels of scrapie contamination are able to cause infection in susceptible sheep genotypes.

Conclusions: Our studies showed that PrPCWD persist in 0.001% CWD contaminated soil for at least 4 year and natural CWD-affected farm soil. When cervid reintroduced into CWD outbreak farm, the strict decontamination procedures of the infectious agent should be performed in the environment of CWD-affected cervid habitat.

Flounder, I couldn't find the answer in the articles. Maybe I missed it. If they depopulate, how long before they can repopulate?

Understandable and I’m sorry to hear about your mother.

repopulation should never happen on a cwd tse prion infected farm, 100% scorched earth policy, they are only kidding themselves when they do not depopulate complete herds imo.

it should be imo, by what science is showing, at least 16 years, but i would go with the 21 years from what the study showed, i posted it below.

and for my private conversations ;

Should Property Evaluations Contain Scrapie, CWD, TSE PRION Environmental Contamination of the land?

***> 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 see here which farmed herd is depopulated or quarantined, and remember, a quarantined cwd infected herd is just a powder keg ready to go off, and will.

https://www.aphis.usda.gov/animal_health/animal_diseases/cwd/downloads/status-of-captive-herds.pdf

i remember a herd in Iowa farmed cwd infected herd, lot of court proceedings, lot of delay, only a few infected, yet while they played in the halls of justice, the cwd tse prion just kept spreading and spreading, there was a call to come cut the fences by local deer farmers, let the herd go before depopulation came. yet in the end, once depopulation occurred, there was a ***79.8 percent of the deer tested positive for the disease. i don't make this stuff up...

The flip side of the coin with that map, one could say:

the free range herds where breeding facilities are getting their deer from have naturally occurring CWD, therefore getting positives in their facilities.

Sure, problem is as soon as ONE breeder gets infected that way then they ship those deer all over the planet and we then end up with maps with dots everywhere being posted on forums.

What about the thousands of facilities not on the map with no cwd around. Your analysis is what I call a “convenient data extrapolation.”

Good thing they didn't buy a deer from an infected breeder. Those places are probably doing it right and keeping their herd healthy, kudos to them.

See the post below yours. CWD didn’t just show up in a breeder pen. Nor did those deer just appear in a pen. God created it. It is naturally occurring. I just want the breeder haters to use common sense instead of reacting based on emotion and self interest(not aimed at any one person)

And breeder operations are tested at a far high percentage compared to free range. Kinda like Covid. Run more tests. Find more positives.

I'd be perfectly content with CWD naturally occurring in NM or West Texas or wherever God put it (probably came from domestic sheep scrapies though eh so can we really blame God?) but now because of shipping deer all over the country I gotta test my deer to be sure I'm not eating an infected one.
