HC Deb 25 March 2004 vol 419 c1000W
Mr. Paterson

To ask the Secretary of State for Environment, Food and Rural Affairs whetherM. bovis can survive in silage clamps. [158362]

Mr. Bradshaw

In a study ofM. bovis survival in silage, M. bovis was recovered from laboratory-prepared silage inoculated with 3.5x106 colony forming units of M. bovis after 24 hours. The organism was not recovered at six or 12 weeks after inoculation. This indicates that it is unlikely that M. bovis will survive the ensiling process for any length of time if silage is properly prepared.
