Bovine spongiform encephalopathy in the United States of America

(Date of previous case of bovine spongiform encephalopathy in the United States of America reported to the OIE: December 2003 [in an imported animal]).

Information received on 27 June 2005 from Dr Peter Fernandez, Associate Administrator, Animal and Plant Health Inspection Service (APHIS), United States Department of Agriculture (USDA), Washington, DC:

Report date: 27 June 2005.

A non-ambulatory or "downer" cow tested "inconclusive" for bovine spongiform encephalopathy (BSE) when tested by a rapid screening test in November 2004 but was confirmed positive in June 2005 using Western Blot test and an immunohistochemical test carried out at the OIE Reference Laboratory for BSE in Weybridge, United Kingdom.

As a downer, the cow was prohibited from entering the human food supply. The carcass of the animal was incinerated.

Source of outbreak or origin of infection: unknown or inconclusive. The affected cow was born before the United States instituted a ruminant-to-ruminant feed ban, which was placed in August 1997. The USDA has initiated an investigation to determine the animal’s herd of origin.

Encefalopatía espongiforme bovina en los Estados Unidos de América

(Fecha del último caso de encefalopatía espongiforme bovina en los Estados Unidos de América señalado a la OIE: diciembre de 2003 [en un animal importado]).

Traducción de información recibida el 27 de junio de 2005 del Dr. Peter Fernández, Administrador Asociado del Servicio de Inspección Zoosanitaria y Fitosanitaria (APHIS), Departamento Federal de Agricultura (USDA), Washington:

Fecha del informe: 27 de junio de 2005.

La prueba rápida de detección de la encefalopatía espongiforme bovina (EEB) que se realizó en noviembre de 2004 en una vaca incapaz de ponerse de pie no dió un resultado concluyente, pero el animal fue confirmado como positivo en junio de 2005 por la prueba de western blot y una prueba inmunohistoquímica, las cuales fueron llevadas a cabo en el Laboratorio de Referencia de la OIE para la EEB en Weybridge (Reino Unido).

En su cualidad de animal "caído", la vaca afectada ha sido excluida del consumo humano. Su cadáver ha sido incinerado.

Fuente del foco u origen de la infección: desconocida o no concluyente. La vaca afectada nació antes de que los Estados Unidos instauraran, en agosto de 1997, la prohibición de alimentar a rumiantes con proteínas derivadas de rumiantes. El USDA ha iniciado una investigación para determinar cuál era el rebaño de origen de este animal.

Encéphalopathie spongiforme bovine aux États-Unis d'Amérique

(Date du dernier cas d'encéphalopathie spongiforme bovine aux Etats-Unis d'Amérique signalé précédemment à l'OIE : décembre 2003 [chez un animal importé]).

Traduction d'informations reçues le 27 juin 2005 du Docteur Peter Fernandez, administrateur associé du service d'inspection zoosanitaire et phytosanitaire (APHIS), département fédéral de l'agriculture (USDA), Washington :

Date du rapport : 27 juin 2005.

Le test rapide de dépistage de l'encéphalopathie spongiforme bovine (ESB) appliqué en novembre 2004 à une vache incapable de se lever a fourni un résultat "non concluant", mais en juin 2005 l'épreuve du western blot et un test immunohistochimique (effectués par le Laboratoire de référence de l'OIE pour l'ESB à Weybridge Royaume-Uni), ont confirmé l'animal comme étant positif.

En tant qu'animal "couché", la vache atteinte avait d'ores et déjà été exclue du circuit de consommation humaine. Sa carcasse a été incinérée.

Source du foyer ou origine de l'infection: inconnue ou incertaine. La vache atteinte est née avant que les Etats-Unis n'instaurent, en août 1997, l'interdiction d'alimenter des ruminants avec des protéines issues de ruminants. L'USDA a débuté une enquête afin de rechercher le troupeau d'origine de cet animal.

THOSE OIE BSE GUIDELINES seem to be terribly flawwed and designed for the trading of all strains of TSEs now, since they went with USA protocols on the MMR regions. THE agent will spread even faster now... TSS

EFSA Scientific Report on the Assessment of the Geographical BSE-Risk (GBR) of the United States of America (USA)
Publication date: 20 August 2004
Adopted July 2004 (Question N° EFSA-Q-2003-083)


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.

Greetings FDA,


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
