§ Mr. CohenTo ask the Minister of Agriculture, Fisheries and Food what information his Department has evaluated on the persistence of scrapie on lands used for the grazing of sheep. [24421]
§ Mrs. BrowningNo studies have been carried out on the persistence of scrapie on lands used for the grazing of sheep. On-going epidemiological studies into scrapie may, however, throw some light on the mechanism of infection. A paper by Wisniewski and others entitled "Mites as vectors for scrapie" which was published inThe Lancet on 20 April is currently being evaluated.
