§ Dr. StrangTo ask the Minister of Agriculture, Fisheries and Food what evidence she has that bovine spongiform encephalopathy is vertically transmissible, from cow to calf, or horizontally transmissible, from cow to cow.
§ Mrs. Gillian ShephardLaboratory-based studies and epidemiological analyses have provided no unequivocal evidence of either vertical or horizontal transmission of BSE. Research is continuing to address these questions and the results will be published in due course.
A letter published in the veterinary record of 12 February stated that the Ministry is aware of 534 confirmed cases of BSE that were offspring of dams which were confirmed cases. This in itself does not prove that transmission was from dam to calf since interpretation of data has been complicated by the fact that most of the positive offspring had also been exposed to ruminant protein.
§ Mr. MorleyTo ask the Minister of Agriculture, Fisheries and Food if she will list, by county, the number of cases of BSE in each month since January 1992.
§ Mr. SoamesThe numbers of cases of BSE in Great Britain listed by month of confirmation and county from January 1992 to January 1994 inclusive, are as follows:
