Dr. Lynn Hillyer:

The way yards are selected for testing or inspection is on a risk basis. I have a database, which we have developed over the past couple of years, of all our licensed trainers and handlers. I use a traffic light system of red, amber and green to rank them. A red yard could be one where there has perhaps been a positive test, there is a concern or intelligence information has come in. A so-called red yard will be visited more frequently than a so-called green yard. Any yard that has never been inspected will be a so-called red yard, by definition, because we need to go in and establish whether there is a post-licensing issue.
