Dstl

Question: To ask the Secretary of State for Defence, if he will take steps to ensure that the new laboratory at DSTL Porton Down, as announced in The Defence Investment Plan, utilises human-relevant new approach technologies, rather than the use of animals.

Answer: Dstl is committed to the principles of Reduction, Replacement and Refinement (‘the 3Rs’) in its use of laboratory animals. The possibility of using alternative methodologies is considered as part of the initial planning of every proposed project, and Home Office licences for animal experimentation are only granted under ASPA if significant benefits will be gained from the research, and all alternative approaches have been carefully considered and implemented where scientifically feasible.
