don't take this as fact or the rules to ad hear to
we did have sheep that were not mv accredited there was a gap betwean them going and mv accredited sheep comming on
to get us mv accredited the vet came blood sampled the 2 ewes sent the samples off the results were clear so we are now mv accredited
the farm was not inspected no extra fencing was erected
if you are mv accredited and non mv stock come on you are back to square one
but i have seen the division betwean mv/none mv flocks being just a farm road with none mv stock grazing up to the mv flock
as fronhaul has said best to contact SAC
