Greetings USDA/APHIS et al,
I would kindly like to comment on OIE proposed guidelines.
AS I said before, OIE should hang up there jock strap now, since it appears they will buckle every time a country makes some political hay about trade protocol, commodities and futures. IF they are not going to be science based, they should do everyone a favor and dissolve there organization. THE reason most every country around the globe came down with BSE/TSE in their cattle, were due to the failed and flawed BSE/TSE testing and surveillance policy of the O.I.E. NOW, they don't even acknowledge atypical scrapie it seems, as one for concern $

Scientific Report of the European Food Safety Authority on the Assessment of the Geographical BSE Risk (GBR) of the USA Question number: EFSA-Q-2003-083
Adopted: 1 July 2004
Summary
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.

Annex to the EFSA Scientific Report (2004) 3, 1-17 on the Assessment of the Geographical BSE Risk of USA - 7 - 2.3
Overall assessment of the external challenge
The level of the external challenge that has to be met by the BSE/cattle system is estimated according to the guidance given by the SSC in its final opinion on the GBR of July 2000 (as updated in January 2002). Live cattle imports: In total the country imported 2038 (other sources) or 1128 (CD) live cattle from BSE risk countries other than Canada, of which 327 (other sources) or 323 (CD) came from the UK. From Canada the imports were >500,000 animals per year. The numbers shown in table 1 are the raw import figures and are not reflecting the adjusted imports for the assessment of the external challenge. Broken down to 5 year periods the resulting external challenge is as given in table 3. This assessment takes into account the different aspects discussed above that allow to assume that certain imported cattle did not enter the domestic BSE-cattle system, i.e. were not rendered into feed. In the case of the USA, all the animals for which tracing information showed that they were not rendered were excluded from the external challenge.
MBM imports:
In total the country imported 689 tons MBM (CD) or 2,230 tons MBM (other sources) from BSE risk countries other than Canada, of which 5 tons (CD) or 101 tons (other sources) were exported from the UK (UK export data). From Canada, the imports were about 30 000 tons per year. The numbers shown in table 2 are the raw import figures and are not reflecting the adjusted imports for the assessment of the external challenge. Broken down to 5 year periods the resulting external challenge is as given in table 3. This assessment takes into account the different aspects discussed above that allow to assume that certain imported MBM did not enter the domestic BSE/cattle system or did not represent an external challenge for other reasons. As it was illegal to export mammalian MBM from UK since 27/03/1996, exports indicated after that date should only have included non-mammalian MBM. In the case of the USA imported MBM from UK in 1989 and between 1997 and 1999 was not taken into account.
Feeding Use of MBM in cattle feed • Until 1997 ruminant MBM (RMBM) could legally be included in cattle feed and was indeed commonly fed to cattle of different age and type. Prior to the feed ban the US authorities estimated that 10% of all MBM would deliberately have been fed to cattle. Feed bans • A ban to feed (several types of) MMBM to ruminants was put in place in August 1997. Derogation from the ban was granted for pure porcine and equine protein (MBM) coming from designated (single species) rendering plants. This MMBM might still be fed to cattle. Therefore this feed ban is a ruminant to ruminant ban. • It is planned to prohibit the use of all mammalian and poultry protein in ruminant feed and prohibiting materials from non-ambulatory disabled cattle and dead stock from use in all animal feed.
Conclusion on the ability to avoid recycling
• Before 1997, US system would not have been able to avoid recycling of the BSEagent to any measurable extent. If the BSE-agent was introduced into the feed chain, it could have reached cattle.
• After the introduction of the 1997 ban in August 1997, the ability to avoid recycling of BSE-infectivity was somewhat improved. However, the rendering of ruminant material (including SRM and fallen stock) is inadequate (non pressurized), and cross-contamination potentials of cattle feed with other feeds remain.
• Therefore, the system is still unable to avoid recycling of BSE-infectivity if already present in the system or incoming.
Feeding
Until August 1997, RMBM was legally fed to cattle. Feeding was therefore "not OK". In August 1997 an RMBM-ban was introduced but feeding of non-ruminant MBM to cattle remained legal as well as feeding of RMBM to non-ruminant animals (farm animals and pets). An RMBM ban is difficult to maintain, as only labels can distinguish the various MMBMs. This makes control of the feed ban very difficult because analytical differentiation between ruminant and non-ruminant MBM is difficult if not impossible.
Due to the highly specialised production system in the USA, various mammalian MBM streams can be separated. Such a feed ban would therefore be assessed as "reasonably OK", for all regions where this highly specialised system exists. However, several areas in the USA do have mixed farming and mixed feed mills, and in such regions an RMBM ban would not suffice. Additionally, official controls for cattle feeds to control for compliance with the ban started in 2002. Thus, for the whole country, the assessment of the feeding after 1997 remains "not OK", but improving.
Rendering
The rendering industry is operating with processes that are not known to reduce
infectivity. It is therefore concluded that rendering was and is "not OK".
SRM-removal
SRM were and are still rendered for feed, as are (parts of) the fallen stock. SRMremoval
is therefore regarded as "not OK".
BSE-surveillance
Before 1989, the ability of the system to identify (and eliminate) BSE-cases was
limited. Since 1990 this ability is improved, thanks to a specific (passive) BSE
surveillance. The initiated introduction of active surveillance in risk populations
should improve the system significantly.
On the basis of the available information, it has to be concluded that the country's
BSE/cattle system was extremely unstable until today, i.e., it would have recycled and
amplified BSE-infectivity very fast, should it have entered the system. The stability of
the BSE/cattle system in the USA overtime is as given in table 4.
The present assessment modifies the stability assessment of the previous GBR report
in 2000 mainly due to a different perception of the impact of BSE surveillance on
stability and of the efficiency of the RMBM feed ban.

Moderate Possibly present
1991 to 1995
Very high

5. CONCLUSION ON THE GEOGRAPHICAL BSE-RISK
5.1 The current GBR as function of the past stability and challenge
• The current geographical BSE risk (GBR) level is III, i.e. it is likely but not
confirmed that domestic cattle are (clinically or pre-clinically) infected with the
BSE-agent.
Note1: It is also worth noting that the current GBR conclusions are not dependent on
the large exchange of imports between USA and Canada. External challenge due to
exports to the USA from European countries varied from moderate to high. These
challenges indicate that it was likely that BSE infectivity was introduced into the
North American continent.

The most recent assessments (and reassessments) were published in June 2005 (Table I; 18), and included the categorisation of Canada, the USA, and Mexico as GBR III. Although only Canada and the USA have reported cases, the historically open system of trade in North America suggests that it is likely that BSE is present also in Mexico.

8 June 1988 Internal CVL meeting to discuss the implications of BSE to Biologicals Products containing bovine extracted material (Annex 6). (YB 88/06.08/11.1-11.2) Following a detailed review of situation the following recommendations were made:
1. Specific concern over use of pituitary gland products by veterinary surgeons and companies. Paper to be produced for Tolworth (Veterinary Medicines Division).
2. Urgent review of all products both immunological and pharmaceutical for possible inclusion of ingredients of bovine origin.
3. Draft guidelines to be presented in full to the National Office of Animal Health (NOAH), the trade body representing the Veterinary Medicines part of the pharmaceutical industry, at next meeting on 11 July 1988

2. We have identified one problem over where we are unable to act and this is the use of gonadotrophins in embryo transfer work. Some veterinary surgeons are quite legally using this exemption from the Medicines Act contained in Section 9(2) to prepare gonadotrophins from pituitary glands from various species, including cattle. These hormones are used to stimulate superovulation in donor cows.
