LETTERS: Breathing in the BSE molecules

Sir: Godfrey Meynell (letter, 8 April) dwells on the virtues of organic farming. But if there is or has been a BSE risk arising from cattle, there must also be a BSE risk from eating "organic" vegetables which have been fertilised with bonemeal and ox-blood rather than chemical fertilisers. Or can the organic lobby give a categorical and scientific assurance that no one has been put at risk by eating organic food?
