Canada Creutzfeldt-Jakob disease surveillance system (CJDSS) report steady rise in cases as of January 2023 and STILL NO CASES REPORTED OF VPSPr CJD
wow, just wow, i don't know where to start with Canada and CJD and strange neurological conditions mounting.
seems the New Brunswick strange neurological cases of unknown origin just still will not go away, and CJD cases in Canada keep rising.

PLEASE NOTE, Canada does not mention VPSPr Variably protease-sensitive prionopathy and you can read why here ;
WHY do some countries count vpspr as sporadic cjd tse prion, and some countries don't?
THIS problem must be addressed immediately imo.
WE have the USA classifying Variably protease-sensitive prionopathy (VPSPr) (formerly known as Protease Sensitive Prionopathy) as sporadic Creutzfeldt Jakob Disease sCJD, and we have Canada not even mentioning in on there statistics links, like vpspr does not even exist, so this is a problem for any valid surveillance imo. IN fact, personal communication from Canada Surveillance et al;
QUOTE;
''Well Terry, we have the data. We simply do not report it separately because we do not believe it has any specific epidemiologic significance, including zoonotic transmission (this opinion is shared unanimously by the international CJD surveillance community, and was established very quickly after the discovery of VPSPr). The key reason in my mind why the US system reports it – in a footnote to their sporadic CJD data – is that they discovered it, and want to follow up on it publicly to validate the reality of their finding scientifically (which is distinct from its significance).''
''The simple answer to your question is that we do not track VPSPr separately, as we view is as a form of sporadic CJD with an unusual phenotype but no specific epidemiological significance. Even the USA surveillance figures do not report it separately.''
end
Hell of a way for a surveillance system for any country to look for any suspect unusual zoonosis zoonotic disease from any mutated TSE Prion strain from any species. ...terry

P.179: Sporadic Creutzfeldt-Jakob disease in Canada
Zheng Wang,1 Gerard Jansen,1,2 Stacy Sabourin,1 Rolande D’Amour,1 Tim Connolly,1 Jennifer Kruse,1 David J Knox,3 Neil R Cashman,4 and Michael B Coulthart1 1The Canadian Creutzfeldt-Jakob Disease Surveillance System; Public Health Agency of Canada; Ottawa, ON Canada; 2Department of Pathology; Ottawa Hospital; Ottawa, ON Canada; 3National Microbiology Laboratory; Public Health Agency of Canada; Winnipeg, MB Canada; 4Brain Research Centre; University of British Columbia; Vancouver, BC Canada
Background. Sporadic Creutzfeldt-Jakob Disease (sCJD) is a fatal, transmissible neurodegenerative disease. Systematic surveillance has repeatedly shown annual mortality in the range 1 to 2 per million population, has elucidated key characteristics of sCJD, and led to recognition of a new form of CJD, variant CJD (vCJD), which is associated with BSE. In 1998, Canada launched comprehensive national CJD surveillance to assess the characteristics of CJD in Canada, identify any acquired cases of CJD (such as vCJD, of which 2 imported cases have been identified in Canada to date), and mitigate public health risks. This study describes the epidemiology of sCJD in Canada from 1998 to 2012.
Methods. Case ascertainment was based on internationally accepted criteria. Demographic and medical information were collected by standardized questionnaire and medical chart review. Poisson regression and descriptive analysis were employed.
Results. A total of 563 sCJD deaths (definite: 462, probable: 101) in Canadian residents were registered from 1998 to 2012. Average annual sCJD mortality was 1.2 per million population, increasing gradually from 0.9 in 1999 to 1.7 in 2012 (P = 0.0004). All provinces saw average annual mortalities ranging from 1.0 to 1.6 (P = 0.25), except three territories where population is small (~25,000 to ~45,000) and no cases were identified. sCJD occurred at similar rates in males (1.1) and females (1.2) (P = 0.21). sCJD was rare under 50 years of age with only 11 cases identified (2.7%). Mortality increased after 50 and peaked at 7.4 per million in the 70–74 age group. Median age at death was 69 and median duration of illness was 4 months. Genotype at codon 129 (N = 358) revealed that the MM subgroup accounted for 223 (62%, median age at death: 69, duration: 4), the MV subgroup was 82 (23%, median age at death: 68, duration: 9), and the VV subgroup was 53 (23%, median age at death: 66, duration: 5). Results of molecular typing (Parchi Scheme) for 256 cases are; MM1: 140, MM2: 11, MV1: 28, MV2: 18, VV1: 5, VV2: 25, Mixture: 29.
Conclusion. Characteristics of sCJD in Canada are consistent with those observed in other countries. The increase in sCJD mortality can be partly attributed to increased awareness of CJD among Canadian clinicians. These findings support the conclusion that Canadian CJD surveillance system is sufficiently sensitive to accurately characterize the epidemiology of sCJD in Canada, and to detect potential additional cases of acquired CJD such as vCJD or human chronic wasting disease.

HD.18: Creutzfeldt-Jakob disease reporting in Canada
Zheng Wang,1 Gerard H. Jansen,1, 2 Elina Olsen,1 Rolande D’Amour,1 Stacy Sabourin,1 Tim Connolly,1 Jennifer Kruse,1 Neil Cashman3 and Michael Coulthart1 1Public Health Agency of Canada; Ottawa, ON CA; 2Department of Pathology; Ottawa Hospital; Ottawa, ON CA; 3Brain Research Centre; University of British Columbia; Vancouver, BC CA
Background. To deal with risks of infectious transmission of Creutzfeldt-Jakob disease (CJD), in 1998 the Government of Canada launched a prospective national CJD surveillance system (CJDSS). In 2000, CJD became nationally notifiable in Canada, and since then all Canadian Provinces and Territories (P/Ts) have made CJD reportable. It has been recognized that the CJDSS registers more cases of CJD than are reported to P/T Ministries of Health (PTMH). Because the CJDSS may not legally share personal information with PTMH, in 2008 the CJDSS began to systematically discuss the issue of CJD reporting with referring health care professionals (HCP). The present study was undertaken to estimate any changes in P/T CJD reporting from 2008, and to identify possible areas for further improvement.
Materials and Methods. P/T CJD data were retrieved from the Public Health Agency of Canada’s National Notifiable Disease System (NNDS) database, and compared with CJDSS data. CJDSS intake sheets were examined, to determine if the case had been reported to the PTMH at the time of notification.
Results. From 2005 to 2010, NNDS received complete data on CJD from 5 P/Ts. During the same period, 134 cases of CJD (probable or neuropathologically confirmed) were reported by the 5 P/Ts while 210 CJD deaths (probable or definite) were recorded in the CJDSS from the same 5 P/Ts. Between 2008 and 2010 there was an increase of ~48% in P/T CJD reports compared with the period 2005–2007. In contrast, the CJDSS registered only ~12% more CJD deaths between 2008 and 2010 compared with 2005–2007, supporting an interpretation of improved P/T reporting. Examination of intake sheets from 172 notifications that were made to the CJDSS from the same 5 P/Ts between 2008 and 2010 revealed that 30 were known to have been reported to PTMH at the time of referring (24 were CJD, 5 were non-CJD, and 1 was unclassifiable). 142 were not reported or had unknown reporting status. Reasons cited by HCPs for not reporting included (1) uncertainty of the CJD diagnosis; (2) uncertainty regarding responsibility for reporting; (3) lack of awareness that CJD is reportable; and (4) uncertainty regarding when or how to report.
Conclusion. The considerable increase of CJD reports in P/Ts since 2008 occurred concurrently with efforts of the CJDSS to engage HCPs on the issue of CJD reporting requirements. P/T CJD reports may include non-CJD cases. Inter-jurisdiction collaboration is underway to further improve CJD reporting.

OR-10: Variably protease-sensitive prionopathy is transmissible in bank voles

Background. Variably protease-sensitive prionopathy (VPSPr) is a recently described “sporadic”neurodegenerative disease involving prion protein aggregation, which has clinical similarities with non-Alzheimer dementias, such as fronto-temporal dementia. Currently, 30 cases of VPSPr have been reported in Europe and USA, of which 19 cases were homozygous for valine at codon 129 of the prion protein (VV), 8 were MV and 3 were MM. A distinctive feature of VPSPr is the electrophoretic pattern of PrPSc after digestion with proteinase K (PK). After PK-treatment, PrP from VPSPr forms a ladder-like electrophoretic pattern similar to that described in GSS cases. The clinical and pathological features of VPSPr raised the question of the correct classification of VPSPr among prion diseases or other forms of neurodegenerative disorders. Here we report preliminary data on the transmissibility and pathological features of VPSPr cases in bank voles.
Materials and Methods. Seven VPSPr cases were inoculated in two genetic lines of bank voles, carrying either methionine or isoleucine at codon 109 of the prion protein (named BvM109 and BvI109, respectively). Among the VPSPr cases selected, 2 were VV at PrP codon 129, 3 were MV and 2 were MM. Clinical diagnosis in voles was confirmed by brain pathological assessment and western blot for PK-resistant PrPSc (PrPres) with mAbs SAF32, SAF84, 12B2 and 9A2.
Results. To date, 2 VPSPr cases (1 MV and 1 MM) gave positive transmission in BvM109. Overall, 3 voles were positive with survival time between 290 and 588 d post inoculation (d.p.i.). All positive voles accumulated PrPres in the form of the typical PrP27–30, which was indistinguishable to that previously observed in BvM109 inoculated with sCJDMM1 cases.
In BvI109, 3 VPSPr cases (2 VV and 1 MM) showed positive transmission until now. Overall, 5 voles were positive with survival time between 281 and 596 d.p.i.. In contrast to what observed in BvM109, all BvI109 showed a GSS-like PrPSc electrophoretic pattern, characterized by low molecular weight PrPres. These PrPres fragments were positive with mAb 9A2 and 12B2, while being negative with SAF32 and SAF84, suggesting that they are cleaved at both the C-terminus and the N-terminus. Second passages are in progress from these first successful transmissions.
Conclusions. Preliminary results from transmission studies in bank voles strongly support the notion that VPSPr is a transmissible prion disease. Interestingly, VPSPr undergoes divergent evolution in the two genetic lines of voles, with sCJD-like features in BvM109 and GSS-like properties in BvI109.
The discovery of previously unrecognized prion diseases in both humans and animals (i.e., Nor98 in small ruminants) demonstrates that the range of prion diseases might be wider than expected and raises crucial questions about the epidemiology and strain properties of these new forms. We are investigating this latter issue by molecular and biological comparison of VPSPr, GSS and Nor98.

Background. Creutzfeldt-Jakob Disease (CJD) is a fatal, transmissible neurodegenerative disease with sporadic, genetic and acquired forms. In 1998, Canada launched comprehensive national CJD surveillance to assess the characteristics of CJD in Canada and its risks to the health of Canadians. This study describes the broad characteristics of CJD in Canada from 1998–2009.
Methods. Case ascertainment was based on internationally accepted criteria. Demographic information and risk-factor data were collected by standardized questionnaire and medical chart review. Poisson regression, descriptive analysis, and case investigation were employed.
Results. A total of 453 CJD deaths in Canadian residents were registered from 1998–2009. Four hundred and fifteen (92%) were sporadic (sCJD), 33 (7%) were genetic and five (1%) were acquired. Average annual sCJD mortality was 1.1 per million population, increasing gradually from 0.9 in 1999 to 1.4 in 2009 (P = 0.27). All provinces saw average annual mortalities ranging from 1.0 to 1.5 (P = 0.85), except three territories where population is small (~25,000 to ~45,000), sCJD occurred equally in both genders at 1.1. sCJD was rare under 50 years of age with only 11 cases identified (2.7%). Mortality increased after 50 and peaked at 8 per million in the 70–74 age group. Median age at death was 69 and median duration of illness was 4 months. Genetic TSE accounted for 33 deaths: 19 were GSS (P102L: 5, D202N: 2, P105T: 2, Q217R:1, A117V: 1, unknown mutation: 8); 13 were familial CJD (E200K: 9, D178N: 2, V203I: 1, V189I:1); one was FFI (D178N). Median age for genetic TSE was 59 and median duration of illness was 27 months. For the five acquired cases of CJD, four were associated with dura mater procedures (3 Lyodura, 1 Tutoplast) and were identified from 1998–2003 in patients aged 14–59. Investigation indicated the infections possibly occurred from 1981–1992 with incubation times from 10–16 years. One biochemically and neuropathologically confirmed variant CJD death occurred in 2002 in a person under 40 years old, likely acquired overseas.
Discussion and Conclusion. Characteristics of CJD in Canada are consistent with those observed in other countries. The increase in sCJD mortality can be at least partly attributed to increased awareness of CJD among referring clinicians. The finding of four dura matter associated CJD cases and one imported vCJD case in Canada demonstrate risks to Canadians from acquired CJD exist. Continued surveillance for iatrogenic risks and novel forms of CJD is warranted.

IF we look at sporadic incidence of CJD in UK from 1993 to 2003, the incidence rose from 37 in 1993 to 77 in 2003. THIS seems to show an increase to me? I do not understand the statement ;
However, in the period following the first published description of vCJD in 1996, there was no increasing trend in the reported annual number of U.K. sporadic CJD deaths (52).
IF we go further and look at some of the other documented BSE countries, you will the increase of sporadic CJD there as well ;

France from 35 to 108

Creutzfeldt Jacob Disease CJD TSE Prion December 2022 Annual Update
***Moreover, sporadic disease has never been observed in breeding colonies or primate research laboratories, most notably among hundreds of animals over several decades of study at the National Institutes of Health25, and in nearly twenty older animals continuously housed in our own facility.***
Even if the prevailing view is that sporadic CJD is due to the spontaneous formation of CJD prions, it remains possible that its apparent sporadic nature may, at least in part, result from our limited capacity to identify an environmental origin.
O.05: Transmission of prions to primates after extended silent incubation periods: Implications for BSE and scrapie risk assessment in human populations

Prion diseases (PD) are the unique neurodegenerative proteinopathies reputed to be transmissible under field conditions since decades. The transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that an animal PD might be zoonotic under appropriate conditions. Contrarily, in the absence of obvious (epidemiological or experimental) elements supporting a transmission or genetic predispositions, PD, like the other proteinopathies, are reputed to occur spontaneously (atpical animal prion strains, sporadic CJD summing 80% of human prion cases).
Non-human primate models provided the first evidences supporting the transmissibiity of human prion strains and the zoonotic potential of BSE. Among them, cynomolgus macaques brought major information for BSE risk assessment for human health (Chen, 2014), according to their phylogenetic proximity to humans and extended lifetime. We used this model to assess the zoonotic potential of other animal PD from bovine, ovine and cervid origins even after very long silent incubation periods.
*** We recently observed the direct transmission of a natural classical scrapie isolate to macaque after a 10-year silent incubation period,
***with features similar to some reported for human cases of sporadic CJD, albeit requiring fourfold long incubation than BSE. Scrapie, as recently evoked in humanized mice (Cassard, 2014),
***is the third potentially zoonotic PD (with BSE and L-type BSE),
***thus questioning the origin of human sporadic cases.
We will present an updated panorama of our different transmission studies and discuss the implications of such extended incubation periods on risk assessment of animal PD for human health.

***Transmission data also revealed that several scrapie prions propagate in HuPrP-Tg mice with efficiency comparable to that of cattle BSE. While the efficiency of transmission at primary passage was low, subsequent passages resulted in a highly virulent prion disease in both Met129 and Val129 mice.
***Transmission of the different scrapie isolates in these mice leads to the emergence of prion strain phenotypes that showed similar characteristics to those displayed by MM1 or VV2 sCJD prion.
***These results demonstrate that scrapie prions have a zoonotic potential and raise new questions about the possible link between animal and human prions.

WS-01: Prion diseases in animals and zoonotic potential
Transmission of the different scrapie isolates in these mice leads to the emergence of prion strain phenotypes that showed similar characteristics to those displayed by MM1 or VV2 sCJD prion.
These results demonstrate that scrapie prions have a zoonotic potential and raise new questions about the possible link between animal and human prions.
Title: Transmission of scrapie prions to primate after an extended silent incubation period)
*** In complement to the recent demonstration that humanized mice are susceptible to scrapie, we report here the first observation of direct transmission of a natural classical scrapie isolate to a macaque after a 10-year incubation period. Neuropathologic examination revealed all of the features of a prion disease: spongiform change, neuronal loss, and accumulation of PrPres throughout the CNS.
*** This observation strengthens the questioning of the harmlessness of scrapie to humans, at a time when protective measures for human and animal health are being dismantled and reduced as c-BSE is considered controlled and being eradicated.
*** Our results underscore the importance of precautionary and protective measures and the necessity for long-term experimental transmission studies to assess the zoonotic potential of other animal prion strains.

CFIA Canada Alberta Laboratory detection of atypical bovine spongiform encephalopathy
I remember another famous quote;
Alberta Premier Ralph Klein has taken aim at the owner of the province's infamous mad cow, saying a "self-respecting" rancher would not have taken the animal to slaughter but instead would have simply "shot, shovelled and shut up."
OIE ATYPICAL BSE 2019
the Group was of the opinion that it would be reasonable to conclude that atypical BSE is potentially capable of being recycled in a cattle population if cattle were to be exposed to contaminated feed. Therefore, the recycling of atypical strains in cattle and broader ruminant populations should be avoided. The Group acknowledged the challenges in demonstrating the zoonotic transmission of atypical strains of BSE in natural exposure scenarios. Overall, the Group was of the opinion that, at this stage, it would be premature to reach a conclusion other than that atypical BSE poses a potential zoonotic risk that may be different between atypical strains.

As a result, since atypical BSE can be reasonably considered to pose a potential background level of risk for any country with cattle, the recycling of both classical and atypical strains in the cattle and broader ruminant populations should be avoided.

Through August 2018, BSE surveillance has identified 26 cases in North America:
6 BSE cases in the United States and 20 in Canada.
Of the 6 cases identified in the United States, one was born in Canada; of the 20 cases identified in Canada, one was imported from the United Kingdom (see graph below).
BSE Cases Identified in Canadian-born Cattle
Update: February 12, 2015 a New Case of BSE Detected in Canada
The Canadian Food Inspection Agency (CFIA) external icon announced the confirmation of another bovine spongiform encephalopathy (BSE) in a beef cow from Alberta born in March 2009. See the CFIAexternal icon notice.
Based on the known or most likely year of birth, an average of 1.4 cases of BSE occurred among the group of animals born each year in Canada from 1991 through 2004. The highest reported number of cases by birth year in a single year, 3 BSE cases, occurred in 2000, 2001 and 2002. The most recently reported case extends the period of BSE transmission in Canada through at least the early half of 2009.

Canadian Food Inspection Agency Confirms Bovine Spongiform Encephalopathy (BSE) in Alberta
Canadian Food Inspection Agency Confirms Bovine Spongiform Encephalopathy (BSE) in Alberta The Canadian Food Inspection Agency (CFIA) has confirmed bovine spongiform encephalopathy (BSE) in a beef cow from Alberta. No part of the animal's carcass entered the human food or animal feed systems.
The Government of Canada is committed to protecting human and animal health and takes the management of BSE very seriously. Immediately upon confirmation of this case, the CFIA launched an investigation and is working closely with provincial and industry partners.
BSE is a progressive, fatal neurological disease in cattle. Canada's last confirmed BSE case was reported in 2011. This latest case was detected through the national BSE surveillance program, which continues to play an important role in Canada's strategy to manage BSE.
As part of the investigation, the CFIA is seeking to confirm the age of the animal, its history and how it became infected. The investigation will focus in on the feed supplied to this animal during the first year of its life. The Agency will also trace out all animals of equivalent risk. Equivalent risk animals will be ordered destroyed and tested for BSE.
Canada remains a "controlled BSE risk" country, as recognized by the World Organisation for Animal Health (OIE). Accordingly, this case should not affect current exports of Canadian cattle or beef.
The case will be reported to the OIE, in line with Canada's international obligations and our commitment to transparency. It will be reported on the CFIA website, as part of the Agency's monthly reportable diseases update.

Operator: Good afternoon, ladies and gentlemen. Bonjour, mesdames et messieurs. Welcome to the Canadian Food Inspection Agency's technical briefing on Bovine Spongiform Encephalopathy in Alberta. Bienvenue à la séance d'information technique sur le cas d'Encéphalopathie spongiforme bovine en Alberta. I would like to turn the meeting over to the technical briefing operator, Mr. Denis Schryburt. J'aimerais maintenant céder la parole au modérateur de cette séance, M. Denis Schryburt. À vous la parole, M. Schryburt. Please go ahead, sir.
Denis Schryburt: Thank you very much. Good afternoon and thank you for joining us today. My name is Denis Schryburt, Media Relations Officer at the Canadian Food Inspection Agency, and I'll be moderating today's technical briefing. I will begin by introducing our speakers who will make a short statement in both official languages and then open it up to the media for questions.
Our first speaker is Paul Mayers, Vice-President, Policy and Programs, followed by Dr. Martine Dubuc, Vice-President, Science, and Delegate for Canada for the World Organization for Animal Health.
Bonjour et merci de vous joindre à nous aujourd'hui. Mon nom est Denis Schryburt, agent des Relations avec les médias à l'Agence canadienne d'inspection des aliments, et j'animerais la séance d'information technique aujourd'hui. Je vais débuter par présenter nos porte-parole qui feront une brève déclaration dans les deux langues officielles et ensuite répondre à vos questions.
Notre premier porte-parole est Paul Mayers, vice-président, Politique et Programmes, suivi par Martine Dubuc, vice-présidente, science, et la délégué pour Canada pour l'Organisation mondiale de la santé animale.
I will now invite Paul Mayers to make a brief statement in English. Mr. Mayers.
Paul Mayers: Thank you, Denis. Good afternoon, everyone, and thank you for calling in today. We'd like to provide some information today on a developing animal health situation. The Canadian Food Inspection Agency has confirmed Bovine Spongiform Encephalopathy, also known as BSE, in a beef cow from Alberta.
First of all, no part of the animal's carcass entered the human food or animal feed system. Canada's suite of internationally recognized safeguards effectively protects the safety of food and animal feed. There is no risk to food safety.
The Government of Canada is committed to protecting human and animal health and takes the management of BSE very seriously. Immediately upon confirmation of this case, the CFIA launched an investigation and is working closely with provincial and industry partners. This investigation will follow the well-developed procedures we've employed in response to previous BSE cases.
Canada's last confirmed BSE case was reported in 2011. This latest case in Alberta was detected through the National BSE Surveillance Program, which is a program that continues to play an important part in Canada's strategy to manage BSE. The fact that we continue to see very high levels of producer participation in the surveillance program underscores the commitment present throughout the cattle and beef sectors to responsibly manage BSE.
The detection of a small number of additional BSE cases is not unexpected in the context of the 30,000 samples we take annually, as Canada continues our ongoing management of this disease.
As has been our practice for CFIA investigations of BSE cases, the Agency is seeking to confirm the age of the animal, its history and how it may have become infected. We're also working to trace out all animals of equivalent risk such as the animals that may have been exposed to the same feed as the infected animal in the first year of its life. Equivalent risk animals will be ordered destroyed, and they will be tested for BSE.
The CFIA will notify the World Organization for Animal Health, also known as the OIE, in line with Canada's international obligations and our commitment to transparency.
This finding should not affect Canada's status as a controlled BSE risk country as recognized by the OIE. Canada continues to effectively manage BSE through a series of integrated safeguards designed to protect both human and animal health. These include prohibiting risk materials from entering the human food and animal feed chains and testing cattle for BSE.
Again, the CFIA is strongly committed to protecting animal health. Our investigation is underway, and we are mobilizing all necessary resources to address this situation.
Thank you.
Denis Schryburt: Thank you, Mr. Mayers. Et maintenant j'invite Martine Dubuc à faire une déclaration en français. Mme Dubuc, s'il-vous-plaît.
Dr Martine Dubuc: Merci. Bonjour à tous, et merci de vous être joints à la téléconférence aujourd'hui. Nous aimerions vous donner aujourd'hui des renseignements sur une situation de santé animale en évolution.
L'Agence canadienne d'inspection des aliments a confirmé un cas d'Encéphalopathie spongiforme bovine, aussi connu sous le nom d'ESB, chez une vache de boucherie provenant de l'Alberta.

Bovine spongiform encephalopathy (BSE) cases have been confirmed in Canada in 2010. BSE is a reportable disease under the "Health of Animals Regulations." This means that all suspected cases must be reported to the CFIA. The following table lists individual animals confirmed to be infected with BSE in Canada in 2010, updated 28 Feb 2010:

The Badger has learned a new case of BSE was discovered 2 weeks ago, but the public was not informed as part of the government's new communication strategy. The decision not to announce new cases of BSE was made in August 2009, and the public was informed by the Canadian Food Inspection Agency (CFIA) online.
"The CFIA is committed to providing all stakeholders, including the general public, media and trading partners, with timely information about disease detections in farmed animals. As such, we have revised how we report online for disease detections in farmed animals to provide a more comprehensive view of Canada's animal health status. All confirmed cases of federally reportable diseases in farmed animals will be centrally located on our website. This information will be updated monthly," explained CFIA spokesperson Jenn Gearey.
The new communication strategy means journalists will not be notified when any new cases of BSE are discovered.
The latest finding of BSE -- Canada's 17th domestic case -- was announced to industry stakeholders, such as processors, on 25 Feb 2010, but not to the media or general public. And while the CFIA claims its reportable diseases page will be updated monthly, no new information has been posted since 31 Jan 2010.
The infection was detected through the national surveillance program in a 6-year-old black angus cow in the same general area of Alberta, home to most of Canada's BSE activity.
The last case discovered in Canada was in May 2009, the only occurrence that year. In 2008, there were 4 incidents; in 2007, there were 3, and in 2006, there were 5 cases of BSE.
Canada's international risk status has not been affected by the latest case.

Canada has confirmed its 17th case of mad cow disease, a finding that will delay any upgrade to its international risk status by one year, a top industry official said on Wednesday [10 Mar 2010].
The animal was born in February 2004, making it Canada's latest-born case of bovine spongiform encephalopathy (BSE). The new case pushes back the earliest date for an upgrade to Canada's controlled risk status from the World Organization for Animal Health (OIE) to 2016, said Ted Haney, president of the Canada Beef Export Federation.
A country cannot apply to upgrade to negligible status sooner than 11 years after the latest-born case of BSE. The process then takes about one year.
Canada, along with many other countries with controlled risk status from the OIE, can ship beef as long as it meets conditions such as disease surveillance.
The infected animal, which has been slaughtered, has not affected trade, Haney said.
The 2003 discovery of the 1st case of mad cow disease on a Canadian farm caused many countries to halt imports of Canadian beef. Most markets have since reopened, but the cattle industry remains in a slump due to other factors such as a strong Canadian dollar.
Mad cow disease is believed to be spread when cattle eat protein rendered from the brains and spines of infected cattle or sheep. Canada banned that practice in 1997.
The Canadian Food Inspection Agency tightened feed rules further in 2007 and said the moves should help eliminate the disease nationally within a decade, although the agency cautioned it still expected to discover the occasional new case.
CFIA spokeswoman Julie LePage confirmed the 17th case but could not provide details of the new case.
The CFIA notified cattle industry officials of the new case late last month [February 2010] but did not issue a news release, Haney said.

[While it may be CFIA's decision on how to notify the public, it may not be in the best interest as far as public relations are concerned. Also, the Reuters article does not make much sense. How can the OIE status change be delayed to 2016 if it is 11 years from the last case? From the CFIA website [article [1] in this posting], it appears the animal was confirmed positive on 25 Feb 2010. Thus, 11 years would be 2021. - Mod.TG] See Also 2009 ---- BSE, bovine - Canada (AB) 20090517.1841 BSE, bovine, 2008 - Canada: (AB, BC) CFIA reports 20090417.1459 2008 ---- BSE, bovine - Canada (04): (BC) 20081119.3648 BSE, bovine - Canada (03): (AB) 20080819.2580 BSE, bovine - Canada (02): (BC) 20080623.1941 BSE, bovine - Canada (AB) 20080226.0786 2007 ---- BSE, bovine - Canada (AB) (03) 20071218.4076 BSE, bovine - Canada (BC) 20070502.1430 BSE, bovine - Canada (AB) (02) 20070308.0813 BSE, bovine - Canada (AB) 20070208.0499 2006 ---- BSE, bovine - Canada (AB)(06) 20061227.3621 BSE, bovine - Canada (AB)(05) 20060825.2413 BSE, bovine - Canada (AB)(04) 20060823.2384 ...................................................tg/msp/lm

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.

BSE [bovine spongiform encephalopathy] case confirmed in Alberta
----------------------------------------------------------------
The Canadian Food Inspection Agency (CFIA) has confirmed bovine spongiform encephalopathy (BSE) in a 6-year-old beef cow from Alberta. No part of the animal's carcass entered the human food or animal feed systems.
The animal's birth farm has been identified, and an investigation is underway. The CFIA is tracing the animal's herdmates at the time of birth and examining possible sources of infection. The age and location of the infected animal are consistent with previous cases detected in Canada.
This case was detected through the national BSE surveillance program, which has been highly successful in demonstrating the low level of BSE in Canada. The program continues to play an important role in Canada's strategy to manage BSE.
Canada remains a Controlled Risk country for BSE, as recognized by the World Organisation for Animal Health (OIE). Accordingly, this case should not affect exports of Canadian cattle or beef.

New mad cow case found in Canada
--------------------------------
A new case of mad cow disease was confirmed in Canada, its 14th case since 2003.
Government inspectors say no part of the animal entered the human food system. The Canadian Food Inspection Agency (CFIA) says the disease was found in a 6-year-old beef cow. The agency did not say where the cow was born. The agency says it is tracing other cattle in the herd and is trying to determine how the cow became infected with the disease. They say the new case should not affect exports of Canadian cattle or beef.
Mad cow disease causes spongy holes in the brain. In people, a rare but fatal form of the disease has been linked to eating infected tissue from cows.
The inspection agency has said a ban on using animal materials in feed products has virtually eliminated the spread of BSE in Canada, but it said a small number of mad cow cases are still expected to surface.

Another mad cow case confirmed
------------------------------
A 6-year-old beef cow was confirmed Friday [15 Aug 2008] as the 13th case of mad cow disease in Alberta, the Canadian Food Inspection Agency said.
It is the 14th confirmed case of bovine spongiform encephalopathy, or BSE, in Canada.
"At this point, it is too early to say how it could have been infected," said Natalie Bragg, a veterinary program specialist with the food inspection agency.
The cow was born, raised, and died on the same farm in northern Alberta, Bragg said. The agency does not release specific locations of infected animals. The animal was euthanized after it became sick. A sample from the animal was tested twice and confirmed as carrying BSE on Friday [15 Aug 2008].
The agency said no traces of BSE made it into either human or animal food supplies. Bragg said the investigation is now focused on the feed on the farm, including how it was transported and stored. The animal was born after a 1997 ban on feed containing cattle or other ruminant parts was introduced.
The agency is also tracking all other animals that were born within a year, and on the same farm, as the dead cow.
Last month [July 2008], it was revealed that Alberta plans to test 50 per cent fewer cattle for BSE by stopping targeted tests of elderly bovines or those without proper documentation. The step was taken because animals that are 9 years old or older are far less likely to contract the diseases, the Alberta government said. Between 2004 and mid-2006, 54 per cent of cattle tested in the province were 9 years or older. 2 of those cows tested positive.
Alberta tests up to 30 000 cattle a year, roughly half of the national BSE monitoring.
Cattle industry officials downplayed the latest BSE discovery, saying it should have little impact on their business, including international beef exports. "So far there has been no major reaction and no markets have closed, and that's because we have kept our international clients educated," said Cam Daniels of Canada Beef Export Federation.
Daniels regularly travels to Japan, China, Mexico, Macau, the Middle East, and other places to talk to importers and distributors. "They understand clearly the control measures we have in place, and they know we're expecting more cases because we are working diligently to find them," he said.
While everyone looks forward to the time when mad cow is eradicated in Canada, some overseas clients view the climbing number of cases as positive right now because it means our surveillance programs are working, said Alberta Beef Producers spokeswoman Lori Creech. "They prefer we find them, rather than in the words of Ralph Klein, 'Shoot, shovel and shut up,' " she said.
"We are very transparent and open as a country. This latest case doesn't affect our status in the world at all because it's not unexpected that they would find another animal with BSE."
The World Organization for Animal Health (OIE) lists Canada as a controlled risk country for BSE.

December 2003, when the USDA et al lost it's supposedly 'GOLD CARD' ie BSE FREE STATUS (that was based on nothing more than not looking and not finding BSE), once the USA lost it's gold card BSE Free status, the USDA OIE et al worked hard and fast to change the BSE Geographical Risk Statuses i.e. the BSE GBR's, and replaced it with the BSE MRR policy, the legal tool to trade mad cow type disease TSE Prion Globally. The USA is doing just what the UK did, when they shipped mad cow disease around the world, except with the BSE MRR policy, it's now legal.Also, the whole concept of the BSE MRR policy is based on a false pretense, that atypical BSE is not transmissible, and that only typical c-BSE is transmissible via feed. This notion that atypical BSE TSE Prion is an old age cow disease that is not infectious is absolutely false, there is NO science to show this, and on the contrary, we now know that atypical BSE will transmit by ORAL ROUTES, but even much more concerning now, recent science has shown that Chronic Wasting Disease CWD TSE Prion in deer and elk which is rampant with no stopping is sight in the USA, and Scrapie TSE Prion in sheep and goat, will transmit to PIGS by oral routes, this is our worst nightmare, showing even more risk factors for the USA FDA PART 589 TSE PRION FEED ban.The FDA PART 589 TSE PRION FEED ban has failed terribly bad, and is still failing, since August 1997. there is tonnage and tonnage of banned potential mad cow feed that went into commerce, and still is, with one decade, 10 YEARS, post August 1997 FDA PART 589 TSE PRION FEED ban, 2007, with 10,000,000 POUNDS, with REASON, Products manufactured from bulk feed containing blood meal that was cross contaminated with prohibited meat and bone meal and the labeling did not bear cautionary BSE statement. you can see all these feed ban warning letters and tonnage of mad cow feed in commerce, year after year, that is not accessible on the internet anymore like it use to be, you can see history of the FDA failure August 1997 FDA PART 589 TSE PRION FEED ban here, but remember this, we have a new outbreak of TSE Prion disease in a new livestock species, the camel, and this too is very worrisome.WITH the OIE and the USDA et al weakening the global TSE prion surveillance, by not classifying the atypical Scrapie as TSE Prion disease, and the notion that they want to do the same thing with typical scrapie and atypical BSE, it's just not scientific.WE MUST abolish the BSE MRR policy, go back to the BSE GBR risk assessments by country, and enhance them to include all strains of TSE Prion disease in all species. With Chronic Wasting CWD TSE Prion disease spreading in Europe, now including, Norway, Finland, Sweden, also in Korea, Canada and the USA, and the TSE Prion in Camels, the fact the the USA is feeding potentially CWD, Scrapie, BSE, typical and atypical, to other animals, and shipping both this feed and or live animals or even grains around the globe, potentially exposed or infected with the TSE Prion. this APHIS Concurrence With OIE Risk Designation for Bovine Spongiform Encephalopathy [Docket No. APHIS-2018-0087], under it's present definition, does NOT show the true risk of the TSE Prion in any country. as i said, it's nothing more than a legal tool to trade the TSE Prion around the globe, nothing but ink on paper.AS long as the BSE MRR policy stays in effect, TSE Prion disease will continued to be bought and sold as food for both humans and animals around the globe, and the future ramifications from friendly fire there from, i.e. iatrogenic exposure and transmission there from from all of the above, should not be underestimated. ...

ONE final comment tonight, i just cannot take anymore. well, ill just let the facts speak for themselves, no need to even comment ;
Section 2. Testing Protocols and Quality Assurance Controls
In November 2004, USDA announced that its rapid screening test, Bio-Rad Enzyme Linked Immunosorbent Assay (ELISA), produced an inconclusive BSE test result as part of its enhanced BSE surveillance program. The ELISA rapid screening test performed at a BSE contract laboratory produced three high positive reactive results.40 As required,41 the contract laboratory forwarded the inconclusive sample to the APHIS National Veterinary Services Laboratories (NVSL) for confirmatory testing. NVSL repeated the ELISA testing and again produced three high positive reactive results.42 In accordance with its established protocol, NVSL ran its confirmatory test, an immunohistochemistry (IHC) test, which was interpreted as negative for BSE. In addition, NVSL performed a histological43 examination of the tissue and did not detect lesions44 consistent with BSE.
Faced with conflicting results, NVSL scientists recommended additional testing to resolve the discrepancy but APHIS headquarters officials concluded no further testing was necessary because testing protocols were followed. In our discussions with APHIS officials, they justified their decision not to do additional testing because the IHC is internationally recognized as the "gold standard." Also, they believed that conducting additional tests would undermine confidence in USDA’s established testing protocols.
