Dr. Damien Barrett:

It is not about labelling farmers. What we envisage is breeding animals being identified. The animals that are of biggest concern to us are breeding cows. Our residual infection modelling shows that the animals that are around for the long haul, the cows, carry a greater risk than the animals that are going to be slaughtered before they reach 30 months. If animals are to be categorised, it will be cows.
