§ Mr. HinchliffeTo ask the Minister of Agriculture, Fisheries and Food what information he has on experiments designed to determine whether vertical transmission of the scrapie agent can occur in sheep.
§ Mr. SoamesEvidence published in the early 1970s confirmed that the foetal membranes collected from scrapie-affected ewes were capable of transmitting infection to sheep and goats following oral challenge. Observations of scrapie incidence in well recorded flocks demonstrate a strong familial pattern of cases in female lines.
