EFSA ASSESSES GEOGRAPHICAL BSE RISK BSE/TSE: A Degenerating Brain Disease According to the World Health Organization (WHO), transmissible spongiform encephalopathies, known as TSEs, are a family of diseases in humans and animals characterised by spongy degeneration of the brain. Different strains of TSE affect different animals. Scrapie is common in sheep and goats.

The BSE crisis and other food scares undermined consumer confidence and triggered the complete overhaul of EU food safety policy. A new comprehensive and integrated approach to food safety was laid down in the White Paper on food safety. This new policy called for the separation of risk assessment from risk management through the creation of a new scientific body charged with providing independent and objective advice concerning risks associated with the food chain, paving the way for the establishment of the European Food Safety Authority in January 2002. In order to manage risks more effectively and ensure the highest level of consumer protection, over 80 different legislative measures were proposed based on a farm to fork approach. In order to address the emergence of mad cow disease, the European Commission introduced a comprehensive set of stringent Community measures to prevent, control and eradicate transmissible spongiform encephalopathies (TSEs) including BSE. Regulation Number 999/2001 establishes measures to limit the spread of the disease and monitor the trade of live animals and animal products. Annex II of the Regulation describes a process for determining a countrys BSE status. The first step involves the initial risk analysis, called Geographical Bovine Spongiform Encephalopathy Risk or GBR. In addition, criteria such as: training of veterinarians and personnel involved in animal trade and slaughter; reporting and examination of animals showing signs of BSE; level of BSE surveillance and monitoring; and laboratory analysis of samples collected are utilised to determine the BSE status of a given country. Herman Koëter EFSAs Deputy Executive Director and Director of Science BSE/TSE Assessment Team continued on page 2 EFSA news 2 Rocky Mountain elk can contract chronic wasting disease. Bovine spongiform encephalopathy (BSE) is a disease of the brain in cattle. It is now generally assumed that its human equivalent, variant Creutzfeldt-Jacob Disease (vCJD), is caused by transmission of BSE to humans. BSE is a fatal disease which has an average incubation period of four to five years. The cause of the disease is still being debated; however strong evidence supports the theory that the agent causing the disease is composed largely, if not entirely, of an abnormally folded protein, called a prion, which converts the normal form of the host protein into the pathological form. It is transmitted to cattle through feeding of BSE-contaminated meat and bone meal supplements. EFSAs BSE/TSE Assessment Team In 2003, the European Commission (EC) asked the European Food Safety Authority (EFSA) to reassess the Geographical Bovine Spongiform Encephalopathy Risk (GBR) for 13 different countries: Australia, Botswana, Canada, Costa Rica, El Salvador, Nicaragua, Namibia, Norway, Mexico, Panama, Swaziland, Sweden and the United States. GBR is a qualitative indicator of the likelihood that one or more cattle are infected with BSE, pre-clinically as well as clinically, at a given point in time, in a specific coun- EFSA assesses Geographical BSE Risk (continued from page 1) try. Where the presence of BSE is confirmed, the GBR gives an indication of the level of infection. To carry out this task, EFSAs Scientific Expert Working Group on the assessment of GBR analyses the most up-to-date scientific data. The TSE/BSE unit at EFSA assists, provides scientific support and co-ordinates the GBR evaluations carried out by external scientific experts. The EFSA team is led by veterinarian, Dr. Bart Goossens. Ir. Rozenn Saunier (microbiologist) and Dr. Wolfgang Gelbmann (veterinarian) provide further scientific support to the expert working group. Administrative assistance is ensured by Angela Cohen and Radika Potier. GBR Assessment The first priority of EFSAs Scientific Expert Working Group was to assess countries with no TSE-related import restrictions to the EU, ie the GBR I countries. The second priority was to determine the GBR of major EU trading partners classified as GBR II. Although the European Commission did not specifically request a GBR assessment for South Africa, the working group decided to do so as it was required in order to carry out those requested for three other countries in the Southern African Region: Botswana, Namibia, Swaziland. BSE Risk Re-assessed for Seven Countries In August, EFSAs Scientific Expert Working Group on Geographic BSE risk assessment issued seven scientific reports for Australia, Canada, Mexico, Norway, South Africa, Sweden and the United States of America. These assessments, which are based on the most recent scientific evidence, have concluded that Australia remains at GBR level I, meaning that the presence of BSE in domestic cattle is highly unlikely. Norway has been raised to level II, which means that the presence of BSE is unlikely, but not excluded. Sweden is unchanged at level II, while Canada and the United States have been raised to level III, which means the presence of BSE is likely, but not confirmed, or confirmed at a lower level. The group also evaluated the status of Mexico and South Africa, both classified as level III. The GBR assessments for the remaining countries will be finalised by the end of 2004. Presence of one or more cattle clinically or pre-clinically infected with the BSE agent in a geographical region/country Highly unlikely Unlikely but not excluded Likely but not confirmed or confirmed at a lower level Confirmed at a higher level GBR of the Country/Region Current status (status before) Australia (I) Norway (I), Sweden (II) Canada (II), Mexico (N/A), South Africa (N/A), USA (II) GBR level I II III IV The full reports of the GBR assessments conducted to date can be found in the Science section of the EFSA website, under Scientific Reports at: http://www.efsa.eu.int/science/efsa_scientific_reports/gbr_assessments/catindex_en.html Additional information on GBR can be found at: http://www.efsa.eu.int/press_room/press_release/575_en.html continued on page 3 EFSA assesses Geographical BSE Risk (continued from page 2) BSE/TSE Testing The testing of animals for BSE using a post mortem laboratory test is required to obtain a complete picture of the epidemiological situation of the disease in cattle. Apart from the removal of specified risk materials (SRMs like spinal cord, brain, eyes, parts of the intestines&) from cattle, sheep and goats - a measure which reduces up to 99% of TSE infectivity - TSE testing in animals is another important means of preventing entry of TSEs into the human food chain. Following a mandate from the European Commission, EFSA has set up a Scientific Expert Working Group on TSE testing which is evaluating new, rapid TSE post mortem tests for cattle and sheep as well as proposals for TSE tests on live animals. The availability of a rapid and accurate diagnostic ante mortem test would be a major advance in dealing with the problem of BSE and TSEs in general. With regard to epidemiological screening, it might in the future offer the possibility of reducing the number of animals to be culled (ie killed and destroyed so as to remove them from the food chain) after detection of one BSE-positive animal in the herd. However, in order to ensure consumer protection, any BSE test performed on live animals should be as reliable as the currently approved post mortem tests. EFSAs Scientific Expert Working Group on TSE testing has recently published two opinions on the design of a field trial protocol for the evaluation of new rapid BSE post mortem tests and for BSE testing in live animals. ?

Adopted July 2004 (Question N° EFSA-Q-2003-083) * 167 kB Report * 105 kB 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. http://www.efsa.eu.int/science/efsa_scientific_reports/gbr_assessments/573_en.html From: Terry S.

PLUS, if the USA continues to flagrantly ignore the _documented_ science to date about the known TSEs in the USA (let alone the undocumented TSEs in cattle), it is my opinion, every other Country that is dealing with BSE/TSE should boycott the USA and demand that the SSC reclassify the USA BSE GBR II risk assessment to BSE/TSE GBR III 'IMMEDIATELY'. for the SSC to _flounder_ any longer on this issue, should also be regarded with great suspicion as well. NOT to leave out the OIE and it's terribly flawed system of disease surveillance. the OIE should make a move on CWD in the USA, and make a risk assessment on this as a threat to human health. the OIE should also change the mathematical formula for testing of disease. this (in my opinion and others) is terribly flawed as well. to think that a sample survey of 400 or so cattle in a population of 100 million, to think this will find anything, especially after seeing how many TSE tests it took Italy and other Countries to find 1 case of BSE (1 million rapid TSE test in less than 2 years, to find 102 BSE cases), should be proof enough to make drastic changes of this system. the OIE criteria for BSE Country classification and it's interpretation is very problematic. a text that is suppose to give guidelines, but is not understandable, cannot be considered satisfactory. the OIE told me 2 years ago that they were concerned with CWD, but said any changes might take years. well, two years have come and gone, and no change in relations with CWD as a human health risk. if we wait for politics and science to finally make this connection, we very well may die before any decisions or changes are made. this is not acceptable. we must take the politics and the industry out of any final decisions of the Scientific community. this has been the problem from day one with this environmental man made death sentence. some of you may think i am exaggerating, but you only have to see it once, you only have to watch a loved one die from this one time, and you will never forget, OR forgive...yes, i am still very angry... but the transmission studies DO NOT lie, only the politicians and the industry do... and they are still lying to this day...TSS http://www.fda.gov/ohrms/dockets/dockets/03n0312/03N-0312_emc-000001.txt
