New TAHC Movement Requirements for Species Susceptible to Chronic Wasting Disease (CWD)
Texas Animal Health Commission (TAHC) July 3, 2013 New TAHC Movement
Requirements for Species Susceptible to Chronic Wasting Disease (CWD)
AUSTIN - The Texas Animal Health Commission (TAHC) has new intrastate
movement requirements in place for elk, red deer, Sika deer, moose and their
hybrids, all of which are considered susceptible to Chronic Wasting Disease
(CWD). White-tailed deer and mule deer are also susceptible species to CWD but
remain under the Texas Parks and Wildlife Department's movement
regulations.
The new TAHC movement rule replaces the previous rule which applied only to
elk and required testing animals based on the number being moved. The TAHC
worked closely with cervid industry representatives to develop new rules that
provide traceability and CWD surveillance of elk, red deer, Sika deer, moose,
and their hybrids, while removing the requirement to sacrifice healthy animals
for testing purposes.
When transporting CWD susceptible species, owners are required to apply an
official identification device to the animals being moved, complete and submit a
CWD Susceptible Species Movement Record, and provide a current estimated
inventory of the herd of origin. In addition, owners are required to provide
documentation of negative CWD test results on 20% of all eligible mortalities in
the herd on an annual basis to the TAHC. Eligible mortalities are those
occurring after June 12, 2013, (the effective date of the new rule), in herd
members 16 months of age and older, including hunter harvested animals and
animals sent to slaughter. The necessary forms, instructions, complete rule and
additional information may be obtained at the TAHC website or by contacting a
local TAHC Region Office.
Herd owners are not required to meet the 20% mortality testing requirement
when transporting animals to a state or federally inspected slaughter facility.
These animals count as eligible mortalities for the herd, however, so owners are
encouraged to test these animals as well as those harvested by hunters to ensure
the herd meets the 20% testing requirement for future movements. Negative CWD
results must be obtained on at least one out of five eligible mortalities to
qualify a herd to move live animals to another premise.
For a copy of the CWD Susceptible Species Movement Record (TAHC Form 13-05)
and the CWD Susceptible Species Inventory Record (TAHC Form 13-06), visit http://www.tahc.texas.gov/animal_health/cwd/cwd.html.
Instructions on how to fill out the forms are attached to the forms along with a
list of acceptable forms of individual identification. Forms may be filled out
online and emailed to CWD_movement@tahc.texas.gov or printed and mailed to the
TAHC Central Office in Austin at P.O. Box 12966, Austin, TX 78711-2966.
"With the disclosure of CWD in mule deer in the Hueco Mountains of Texas in
2012, coupled with the newly required designation of red Deer and Sika deer as
susceptible species, it is imperative that surveillance is increased in those
species and movement of those susceptible species be traceable", said Dr. Greg
Hawkins, TAHC Region 4 Director.
To read the rule in detail, visit www.tahc.texas.gov.
Founded in 1893, the Texas Animal Health Commission works to protect the
health of all Texas livestock, including: cattle, swine, poultry, sheep, goats,
equine animals, and exotic livestock.

Chronic Wasting Disease CWD TEXAS UPDATE ON REGULATION RULES
Sunday, June 09, 2013
Missouri House forms 13-member Interim Committee on the Cause and Spread of
Chronic Wasting Disease CWD
*** The potential impact of prion diseases on human health was greatly
magnified by the recognition that interspecies transfer of BSE to humans by beef
ingestion resulted in vCJD. While changes in animal feed constituents and
slaughter practices appear to have curtailed vCJD, there is concern that CWD of
free-ranging deer and elk in the U.S. might also cross the species barrier.
Thus, consuming venison could be a source of human prion disease. Whether BSE
and CWD represent interspecies scrapie transfer or are newly arisen prion
diseases is unknown. Therefore, the possibility of transmission of prion disease
through other food animals cannot be ruled out. There is evidence that vCJD can
be transmitted through blood transfusion. There is likely a pool of unknown size
of asymptomatic individuals infected with vCJD, and there may be asymptomatic
individuals infected with the CWD equivalent. These circumstances represent a
potential threat to blood, blood products, and plasma supplies.

Following its Discovery

DEFRA U.K. What is the risk of Chronic Wasting Disease CWD being
introduced into Great Britain? A Qualitative Risk Assessment October 2012
snip...
In the USA, under the 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.
Animals considered at high risk for CWD include:
1) animals from areas declared to be endemic for CWD and/or to be CWD
eradication zones and
2) deer and elk that at some time during the 60-month period prior to
slaughter were in a captive herd that contained a CWD-positive animal.
Therefore, in the USA, materials from cervids other than CWD positive
animals may be used in animal feed and feed ingredients for non-ruminants.
The amount of animal PAP that is of deer and/or elk origin imported from
the USA to GB can not be determined, however, as it is not specified in TRACES.
It may constitute a small percentage of the 8412 kilos of non-fish origin
processed animal proteins that were imported from US into GB in 2011.
Overall, therefore, it is considered there is a __greater than negligible
risk___ that (nonruminant) animal feed and pet food containing deer and/or elk
protein is imported into GB.
There is uncertainty associated with this estimate given the lack of data
on the amount of deer and/or elk protein possibly being imported in these
products.
snip...
36% in 2007 (Almberg et al., 2011). In such areas, population declines of
deer of up to 30 to 50% have been observed (Almberg et al., 2011). In areas of
Colorado, the prevalence can be as high as 30% (EFSA, 2011).
The clinical signs of CWD in affected adults are weight loss and
behavioural changes that can span weeks or months (Williams, 2005). In addition,
signs might include excessive salivation, behavioural alterations including a
fixed stare and changes in interaction with other animals in the herd, and an
altered stance (Williams, 2005). These signs are indistinguishable from cervids
experimentally infected with bovine spongiform encephalopathy (BSE).
Given this, if CWD was to be introduced into countries with BSE such as
GB, for example, infected deer populations would need to be tested to
differentiate if they were infected with CWD or BSE to minimise the risk of BSE
entering the human food-chain via affected venison.
snip...
The rate of transmission of CWD has been reported to be as high as 30% and
can approach 100% among captive animals in endemic areas (Safar et al., 2008).
snip...
In summary, in endemic areas, there is a medium probability that the soil
and surrounding environment is contaminated with CWD prions and in a
bioavailable form. In rural areas where CWD has not been reported and deer are
present, there is a greater than negligible risk the soil is contaminated with
CWD prion.
snip...
In summary, given the volume of tourists, hunters and servicemen moving
between GB and North America, the probability of at least one person travelling
to/from a CWD affected area and, in doing so, contaminating their clothing,
footwear and/or equipment prior to arriving in GB is greater than negligible.
For deer hunters, specifically, the risk is likely to be greater given the
increased contact with deer and their environment. However, there is significant
uncertainty associated with these estimates.
snip...
Therefore, it is considered that farmed and park deer may have a higher
probability of exposure to CWD transferred to the environment than wild deer
given the restricted habitat range and higher frequency of contact with tourists
and returning GB residents.

TEXAS border) posted by Ken Waldrup, DVM, PhD on December 15, 2003 at 3:43 pm:
HEllo Dr. Waldrup,
thank you for your comments and time to come to this board.
Ken Waldrup, DVM, PhD states;
> it is painfully obvious that you do not know or understand the natural
distribution of mule deer out there or the rights of the land owners in this
state...
TSS states;
I am concerned about all deer/elk not just mule deer, and the rights of
land owners (in the case with human/animal TSEs) well i am not sure of the
correct terminology, but when the States deer/elk/cattle/sheep/humans are at
risk, there should be no rights for land owners in this case. the state should
have the right to test those animals. there are too many folks out there that
are just plain ignorant about this agent. with an agent such as this, you cannot
let landowners (and i am one) dictate human/animal health, especially when you
cannot regulate the movement of such animals...
Ken Waldrup, DVM, PhD states;
> Deer and elk from the Guadalupe Peak National Park cannot be collected
with federal permission.
TSS states;
I do not understand this? so there is no recourse of action even if every
deer/elk was contaminated with CWD in this area (hypothetical)?
Ken Waldrup, DVM, PhD states;
> I am concerned about your insinuation that CWD is a human health risk.
We are at a stand-off - you have no proof that it is and I have no definitive
proof that it isn't. However I would say that the inferred evidence from
Colorado, Wyoming and Wisconsin suggests that CWD is not a human health concern
(i.e. no evidence of an increased incidence of human brain disorders within the
CWD "endemic" areas of these states)...
TSS states;
NEXT, let's have a look at the overall distribution of CWD in Free-Ranging
Cervids and see where the CWD cluster in NM WSMR borders TEXAS;
Current Distribution of Chronic Wasting Disease in Free-Ranging Cervids
NOW, the MAP of the Exoregion where the samples were taken to test for CWD;
CWD SURVEILLANCE SAMPLE SUBMISSIONS TEXAS
Ecoregions of TEXAS
IF you look at the area around the NM WSMR where the CWD cluster was and
where it borders TEXAS, that ecoregion is called Trans Pecos region. Seems if my
Geography and my Ciphering is correct ;-) that region only tested 55% of it's
goal. THE most important area on the MAP and they only test some 96 samples,
this in an area that has found some 7 positive animals? NOW if we look at the
only other border where these deer from NM could cross the border into TEXAS,
this area is called the High Plains ecoregion, and again, we find that the
sampling for CWD was pathetic. HERE we find that only 9% of it's goal of CWD
sampling was met, only 16 samples were tested from some 175 that were suppose to
be sampled.
AS i said before;
> SADLY, they have not tested enough from the total population to
> know if CWD is in Texas or not.
BUT now, I will go one step further and state categorically that they are
not trying to find it. just the opposite it seems, they are waiting for CWD to
find them, as with BSE/TSE in cattle, and it will eventually...

One major change that was adopted as a result of the new federal
regulations is the sample collection for diagnostic testing of CWD.
Under the old regulations, owners were only required to collect and submit
a sample of the obex (brainstem) to the laboratory for testing. The new federal
changes require owners to collect and submit a sample of both the obex and
retropharyngeal lymph nodes for a more complete diagnostic testing.
