HL Deb 15 January 2001 vol 620 c119WA
The Countess of Mar

asked Her Majesty's Government:

Upon what scientific evidence was based the statement made by the Minister of Agriculture, Fisheries and Food on Radio 4 on Monday 4 December that prion proteins were the infectious agents for BSE. [HL92]

The Minister of State, Ministry of Agriculture, Fisheries and Food (Baroness Hayman):

While there are a number of alternative theories as to the causal agents for BSE, the majority of the scientific evidence available points to the primary role of prion proteins. None of the ongoing studies on alternative theories has to date produced compelling evidence to suggest that prions are not implicated.
