U.S. appeals court OKs Canada beef imports
Tue Aug 28, 2007 2:17 PM EDT

By Adam Tanner

SAN FRANCISCO (Reuters) - A U.S. appeals court gave the green light on
Tuesday to continued Canadian beef and cattle imports, rejecting a rancher
group's effort to impose a ban amid mad cow disease concerns.

The Montana-based Ranchers Cattlemen Action Legal Fund United Stockgrowers
of America (R-CALF) argued that live Canadian cattle posed a risk of mad cow
disease to the U.S. cattle herd and should be banned.

The U.S. Department of Agriculture said Canada had safeguards in place to
prevent the spread of the deadly disease, also known as bovine spongiform
encephalopathy (BSE).

"Having reviewed the merits of this case, we conclude that the agency
considered the relevant factors and articulated a rational connection
between the facts found and its decision to designate Canada a minimal-risk
country," Judge Cynthia Holcomb Hall wrote for the U.S. 9th Circuit Court of
Appeals.

The U.S. government imposed a ban on Canadian cattle after Canada found its
first domestic case of mad cow disease in 2003. It planned to reopen the
border in 2005 to imports of Canadian cattle, but R-CALF obtained a
temporary injunction from a federal court in Montana.

The USDA appealed to the 9th Circuit, which rejected R-CALF's arguments and
reopened the U.S. border to shipments of Canadian cattle. The Montana
federal court in 2006 also ruled in favor of the USDA.

A three-judge 9th Circuit panel based in San Francisco re-examined another
R-CALF appeal in its Tuesday ruling.

"R-CALF's extra-record evidence has failed to convince us that the agency's
review was unauthorized, incomplete, or otherwise improper," Judge Hall
wrote.

The decision went point by point through R-CALF's arguments but found fault
in them.

"The agency -- at the time it made its decision -- properly relied on
studies from both the World Organization for Animal Health and the Harvard
Center on Risk Analysis finding that feed bans were the most effective way
to prevent the spread of BSE," the court wrote. "It bears repeating that the
agency did not assume 100 percent effectiveness of its measures."

Mad cow disease has infected more than 187,000 cattle over the past two
decades, and about 150 people have died from a variant, Creutzfeld-Jakob
Disease, which has been linked to BSE-contaminated meat, the court wrote in
its summary of the case.

Shae Dodson, a spokeswoman for R-CALF, said the group's board would have to
vote whether to appeal the case to the U.S. Supreme Court.

EFSA Scientific Report on the Assessment of the Geographical BSE-Risk (GBR) of the United States of America (USA)
Last updated: 19 July 2005
Adopted July 2004 (Question N° EFSA-Q-2003-083)

Report
Summary
Summary of the Scientific Report

The European Food Safety Authority and its Scientific Expert Working Group on the Assessment of the Geographical Bovine Spongiform Encephalopathy (BSE) Risk (GBR) were asked by the European Commission (EC) to provide an up-to-date scientific report on the GBR in the United States of America, i.e. the likelihood of the presence of one or more cattle being infected with BSE, pre-clinically as well as clinically, in USA. This scientific report addresses the GBR of USA as assessed in 2004 based on data covering the period 1980-2003.

The BSE agent was probably imported into USA and could have reached domestic cattle in the middle of the eighties. These cattle imported in the mid eighties could have been rendered in the late eighties and therefore led to an internal challenge in the early nineties. It is possible that imported meat and bone meal (MBM) into the USA reached domestic cattle and leads to an internal challenge in the early nineties.

A processing risk developed in the late 80s/early 90s when cattle imports from BSE risk countries were slaughtered or died and were processed (partly) into feed, together with some imports of MBM. This risk continued to exist, and grew significantly in the mid 90’s when domestic cattle, infected by imported MBM, reached processing. Given the low stability of the system, the risk increased over the years with continued imports of cattle and MBM from BSE risk countries.

EFSA concludes that the current GBR level of USA is III, i.e. it is likely but not confirmed that domestic cattle are (clinically or pre-clinically) infected with the BSE-agent. As long as there are no significant changes in rendering or feeding, the stability remains extremely/very unstable. Thus, the probability of cattle to be (pre-clinically or clinically) infected with the BSE-agent persistently increases.

EFSA Scientific Report on the Assessment of the Geographical BSE-Risk (GBR) of Canada

Summary of the Scientific Report

The European Food Safety Authority and its Scientific Expert Working Group on the Assessment of the Geographical Bovine Spongiform Encephalopathy (BSE) Risk (GBR) were asked to provide an up-to-date scientific report on the GBR in Canada, i.e. the likelihood of the presence of one or more cattle being infected with BSE, pre-clinically as well as clinically, in Canada. This scientific report addresses the GBR of Canada as assessed in 2004 based on data covering the period 1980-2003.

The BSE agent was probably imported into the country middle of the eighties and could have reached domestic cattle in the early nineties. These cattle imported in the mid eighties could have been rendered in the late eighties and therefore led to an internal challenge in the early 90s. It is possible that imported meat and bone meal (MBM) into Canada reached domestic cattle and led to an internal challenge in the early 90s.

A certain risk that BSE-infected cattle entered processing in Canada, and were at least partly rendered for feed, occurred in the early 1990s when cattle imported from UK in the mid 80s could have been slaughtered. This risk continued to exist, and grew significantly in the mid 90’s when domestic cattle, infected by imported MBM, reached processing. Given the low stability of the system, the risk increased over the years with continued imports of cattle and MBM from BSE risk countries.

EFSA concludes that the current GBR level of Canada is III, i.e. it is confirmed at a lower level that domestic cattle are (clinically or pre-clinically) infected with the BSE-agent. As long as the system remains unstable, it is expected that the GBR continues to grow, even if no additional external challenges occur.

TSE UPDATE USA AUGUST 2007


AN update on cwd and other TSE in the USA. instead of another long winded
post (i do get long winded some times), i have posted links to TSE topics
that probably most of you are not aware of, most probably don't care. lot of
wasted days and wasted nights, a decade in december, but you only have to
see it once. take this with how ever many grains of salt you wish, but
please take it seriously. ...

thank you,

Transmissible Spongiform Encephalopathy update


Subject: Cross-sequence transmission of sporadic Creutzfeldt-Jakob disease
creates a new prion strain

Date: August 25, 2007 at 12:42 pm PST

snip...


In this study, the strain-dependent traits of sCJDMM1
prions were inherited through cross-sequence
transmission without any modification. The
humanized mice with 129V/V produced type 1 PrPres
after inoculation with sCJD-MM1 prions. Because
sCJD-VV1 cases are extremely rare (at most 1-2%
of the total number of sCJD cases) and characterized
by early onset (mean age at onset: 39.3 years) (5),

####################################

our results raise the possibility that CJD cases
classified as VV1 may include cases caused by
iatrogenic transmission of sCJD-MM1 prions or
food-borne infection by type 1 prions from animals,
e.g., chronic wasting disease prions in cervid. In fact,
two CJD-VV1 patients who hunted deer or
consumed venison have been reported (40, 41). The
results of the present study emphasize the need for
traceback studies and careful re-examination of the
biochemical properties of sCJD-VV1 prions.

###################################

In conclusion, cross-sequence transmission of
sCJD-VV2 prions generates a new prion strain with
altered conformational properties and disease
phenotypes as p-dCJD prions. Furthermore, the
newly generated prions have unique transmissibility
including the traceback phenomenon. In the future, if
atypical prion strains emerge through cross-sequence
transmission, especially from animals, traceback
studies will enable us to identify the origin of the
prions.
