Feds back Quebec R+D for SRM removal equipment
Dec 17, 2011 12:30 AM
A southern Quebec manufacturer of slaughter, cutting and deboning equipment has picked up over $400,000 in federal funds to develop new ways of removing specified risk materials (SRMs) from carcasses at abattoirs.
Industries Riopel, based at Vallee-Jonction, about 65 km southeast of Quebec City in the Chaudiere-Appalaches district, will get over $404,000 from the federal Slaughter Waste Innovation Program (SWIP), the government said Friday.
The SWIP funding is meant to back two separate research and development projects at Riopel to "maximize" the removal of SRMs and high-risk tissues from carcasses processed by Canadian abattoirs, the government said.
SRMs are the nervous-system tissues known to harbour the prions that cause bovine spongiform encephalopathy (BSE) in infected cattle.
The new SRM handling equipment Riopel is developing "will reduce waste materials and disposal costs, cutting back on the volume of SRM sent to landfills and also reduce greenhouse gas emissions associated with their transportation," the government said.
As well, the meat processing industry is expected to benefit from the "knowledge and expertise" related to SRM handling to be gained from the research aspect of the projects at Riopel, the government said.
"The new equipment being developed will also reduce the volume of (SRM) being disposed of, while at the same time ensuring compliance with Canada's regulatory requirements," local MP Maxime Bernier, the federal minister of state for small business and tourism, said in the government's release.
SWIP, budgeted for $40 million over three years, passed its third intake deadline on Oct. 31, to support research, development and commercialization or adoption of technologies and processes for SRMs' removal, disposal or use.
The program requires successful applicants to complete their projects before the end of March 2013.

Greetings Canadian Cattleman/woman et al,
I applaud your continued efforts to eradicate the BSE TSE prion agent from your Cattle, thus, removing any risk factors further for human infection there from. removing SRMs (specified risk materials) the most high risk materials that would contain the TSE prion agent. However, I kindly remind you that with these new atypical BSE strains, and SRMs there from, it would seem that there should be an enhancement of the SRM removal. some in the feed industry are wanting to relax these BSE feed rules, and this would be a terrible mistake, one that would take 30 years of trying to eradicate this TSE prion agent, it would take it back to day one. a foolish move indeed if it were to take place. I kindly wish to post below some new science on the TSE prion agent. please remember, the risk of Chronic Wasting Disease CWD in cervids to not only humans, but to livestock as well is very real, especially since we now know that CWD has mutated into a 2nd strain. do not let your guard down. sadly, the USA is still in denial mode about BSE or any type TSE in the USA livestock, and that should prove to the OIE and the world (with the existing evidence of flawed surveillance, and flawed feed ban to as late as 2007) that the USA is indeed at least still a BSE GBR 3 risk level. ...

Prion Uptake in the Gut: Identification of the First Uptake and Replication Sites
http://transmissiblespongiformencephalopathy.blogspot.com/2011/12/prion-uptake-in-gut-identification-of.html
Discussion: The C, L and H type BSE cases in Canada exhibit molecular characteristics similar to those described for classical and atypical BSE cases from Europe and Japan. This supports the theory that the importation of BSE contaminated feedstuff is the source of C-type BSE in Canada.
*** It also suggests a similar cause or source for atypical BSE in these countries.

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.

Abstract.
A distinct strain of scrapic identified in sheep of Norway in 1998 has since been identified in numerous countries throughout Europe. The disease is known as Nor98 or Not-98-like scrapic. among other names. Distinctions between classic scrapie and Nor98 scrapie are made based on histopathologv and immunodiagnostic results. There are also differences in the epidemiology, typical signalment, and likelihood of clinical signs being observed. In addition, sheep that have genotypes associated with resistance to classic scrapie are not spared from Nor98 disease. The various differences between classic and Nor98 scrapie have been consistently reported in the vast majority of cases described across Europe. The current study describes in detail the patholo gic changes and diagnostic results of the first 6 cases of' Nor98 scrapic disease diagnosed in sheep of the United States.
Key words: Hisiopathology: Nor98: PrP imniunolabeling; scrapie: sheep.

Results
Case I
The first case identified as consistent with Nor98 scrapie had nonclassic PrP distribution in brain tissue, no PrPSC in lymph tissue, and nonclassic migration of protein bands on a Western blot test. The animal was an aged, mottled-faced ewe that was traced back to a commercial flock in Wyoming. ...
Case 2
The second case was a clinically normal 8-year-old Suffolk ewe that had been in a quarantined flock for 5 years at a USDA facility in Iowa.
Case 3
A 16-year-old, white-faced, cross-bred wether was born to a black-faced ewe. He lived his entire life as a pet on a farm in California.
Case 4
The fourth case of Nor98 scrapie was identified in an approximately 8-year-old Dorset ewe that was born into a flock of approximately 20 ewes in Indiana.
Case 5
The fifth case was a clinically normal, approximately 3-year-old, white-faced, cross-bred ewe from an approximately 400 head commercial flock in Minnesota.
Case 6
The sixth case of Nor98 scrapie was identified in a 4-year-old, white-faced ewe that was purchased and added to a commercial flock in Pennsylvania

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.
SNIP...
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).

*** 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.

Infectivity in skeletal muscle of BASE-infected cattle

Groschup3, Anne Buschmann3, Cristina Casalone4, Maria Caramelli4, Salvatore Monaco5, Gianluigi Zanusso5, Fabrizio Tagliavini1 1Carlo Besta" Neurological Institute,Italy; 2IZS Brescia, Italy; 33FLI Insel Riems, D, Germany; 4CEA-IZS Torino, Italy; 5University of Verona, Italy
Background: BASE is an atypical form of bovine spongiform encephalopathy caused by a prion strain distinct from that of BSE. Upon experimental transmission to cattle, BASE induces a previously unrecognized disease phenotype marked by mental dullness and progressive atrophy of hind limb musculature. Whether affected muscles contain infectivity is unknown. This is a critical issue since the BASE strain is readily transmissible to a variety of hosts including primates, suggesting that humans may be susceptible.
Objectives: To investigate the distribution of infectivity in peripheral tissues of cattle experimentally infected with BASE. Methods: Groups of Tg mice expressing bovine PrP (Tgbov XV, n= 7-15/group) were inoculated both i.c. and i.p. with 10% homogenates of a variety of tissues including brain, spleen, cervical lymph node, kidney and skeletal muscle (m. longissimus dorsi) from cattle intracerebrally infected with BASE. No PrPres was detectable in the peripheral tissues used for inoculation either by immunohistochemistry or Western blot.
Results: Mice inoculated with BASE-brain homogenates showed clinical signs of disease with incubation and survival times of 175±15 and 207±12 days. Five out of seven mice challenged with skeletal muscle developed a similar neurological disorder, with incubation and survival times of 380±11 and 410±12 days. At present (700 days after inoculation) mice challenged with the other peripheral tissues are still healthy. The neuropathological phenotype and PrPres type of the affected mice inoculated either with brain or muscle were indistinguishable and matched those of Tgbov XV mice infected with natural BASE.
Discussion: Our data indicate that the skeletal muscle of cattle experimentally infected with BASE contains significant amount of infectivity, at variance with BSE-affected cattle, raising the issue of intraspecies transmission and the potential risk for humans. Experiments are in progress to assess the presence of infectivity in skeletal muscles of natural BASE.

Atypical BSE in Cattle
To date the OIE/WAHO assumes that the human and animal health standards set out in the BSE chapter for classical BSE (C-Type) applies to all forms of BSE which include the H-type and L-type atypical forms. This assumption is scientifically not completely justified and accumulating evidence suggests that this may in fact not be the case. Molecular characterization and the spatial distribution pattern of histopathologic lesions and immunohistochemistry (IHC) signals are used to identify and characterize atypical BSE. Both the L-type and H-type atypical cases display significant differences in the conformation and spatial accumulation of the disease associated prion protein (PrPSc) in brains of afflicted cattle. Transmission studies in bovine transgenic and wild type mouse models support that the atypical BSE types might be unique strains because they have different incubation times and lesion profiles when compared to C-type BSE. When L-type BSE was inoculated into ovine transgenic mice and Syrian hamster the resulting molecular fingerprint had changed, either in the first or a subsequent passage, from L-type into C-type BSE.
In addition, non-human primates are specifically susceptible for atypical BSE as demonstrated by an approximately 50% shortened incubation time for L-type BSE as compared to C-type. Considering the current scientific information available, it cannot be assumed that these different BSE types pose the same human health risks as C-type BSE or that these risks are mitigated by the same protective measures.
This study will contribute to a correct definition of specified risk material (SRM) in atypical BSE. The incumbent of this position will develop new and transfer existing, ultra-sensitive methods for the detection of atypical BSE in tissue of experimentally infected cattle.

Seven main threats for the future linked to prions
First threat
The TSE road map defining the evolution of European policy for protection against prion diseases is based on a certain numbers of hypotheses some of which may turn out to be erroneous. In particular, a form of BSE (called atypical Bovine Spongiform Encephalopathy), recently identified by systematic testing in aged cattle without clinical signs, may be the origin of classical BSE and thus potentially constitute a reservoir, which may be impossible to eradicate if a sporadic origin is confirmed.
***Also, a link is suspected between atypical BSE and some apparently sporadic cases of Creutzfeldt-Jakob disease in humans. These atypical BSE cases constitute an unforeseen first threat that could sharply modify the European approach to prion diseases.
Second threat
