SEAC 102nd Meeting on Wednesday 4 March 2009 (SEE DH risk assessment on sourcing and pooling plasma)


snip...



ITEM 3 - CURRENT ISSUES 8. SEAC was informed about the following issues: . A mother and son in Spain had died of variant Creutzfeldt-Jakob Disease (vCJD). This is the first recorded instance of more than one case of vCJD within one family. As both the mother and son lived in a region of Spain with a history of BSE, had frequently shared meals of cattle brain, and as no other risk factor has been identified, it seems most likely that both infections were acquired from dietary exposure. Furthermore, the similar times of onset of disease of the cases did not suggest transmission had occurred from one to the other.

21. A member asked if it was possible to translate the estimates of infectivity into a number of potential additional cases of vCJD. Dr Comer explained that such estimates would rely upon a number of assumptions where there would be large uncertainties, producing results with very large uncertainties. Human exposure expressed as bovine oral ID50 may be more easily understood, aiding decision making. A member noted that the possibility of human-to-human transmission made estimating the potential number of vCJD cases for a given level of dietary exposure to BSE more complex. Members agreed that it was important to communicate to consumers the reasons why such estimates are so difficult to make.

24. Dr Victor Del Rio Vilas (VLA) presented an overview of the study conducted between July 2005 and November 2007. The aim was to characterise cases of atypical scrapie, particularly with regard to their holdings of origin and to examine any association between variables related to the holdings and the occurrence of atypical scrapie. Forty case holdings and 119 control holdings were analysed. Data were collected from interviews with farmers with a questionnaire, producing 260 analytical variables. A statistical analysis of the data collected showed that a small number of variables, including certain animal feeds, were associated with an increase in the odds of atypical scrapie being present. Some variables appeared protective against atypical scrapie.

ISSUE


1. The Department for Environment, Food and Rural Affairs (Defra) has asked SEAC to consider a research article (Annex A) entitled "Idiopathic Brainstem Neuronal Chromatolysis (IBNC): a novel prion protein related disorder of cattle?" produced by the Veterinary Laboratories Agency.


2. Martin Jeffrey, the lead author of the article, will be present at the meeting to present an overview and answer questions.

0206290030: BRAINS OF BOVINE ANIMALS, EDIBLE, FROZEN

U.S. Domestic Exports: December 2004 and 2004 Year-to-Date, not Seasonally Adjusted


Greetings,

I find it very disturbing that the USA is exporting all these products all over the globe without proper testing for BSE/TSE. I wonder if the consumer in these countries know what they are getting?

WHO is to say that some of these nvCJD cases are not from imported USA product?
