    Hi GLP regs mention about separate storage/handling of test and control items. How about test and control animal groups? Is it permissable (if not best practice) to house test and control animals in the same pen? Can you advise of any regulations/advisory documents on this matter. Kind Regards Alan

    Dear Alan, Routinely, in large animal studies, there should be separation of control and treated animals. There may occasionally be only a small number of animals on test and therefore, if welfare requirements mean that the animals should be group housed then there maybe justification for this, depending on dose route. It might also be possible to house a non-study animal with the study animals for welfare reasons. This should be a discussion between your QA and your NACWO and the decision documented as to the agreed solution. Be careful with this, it is preferable to avoid this situation if at all possible.
