I extend my gratitude to everyone who has returned to the debate, as some hon. Members will have detected that I was getting towards the end of my contribution. I have gone through my notes to check whether I overlooked anything earlier.
To pick up on the point made by my hon. Friend the Member for The Cotswolds on the culls that have completed their four years, as I explained just before we suspended the debate, at the end of last year we consulted on having low-level maintenance culling to keep the population in check. That would very much be a small operation with much-reduced numbers—not like the
culls we had for the first four years. My hon. Friend also mentioned deer and other species, and he is right that wild deer can carry TB, but our veterinary advice is that their role in transmitting TB is significantly lower than that of badgers, because of their nature and how they move about. TB spreads less freely among deer, because badgers live underground in close proximity to one another. Nevertheless, deer are a potential concern, but we believe badgers to be far more prevalent in spreading the disease, and do so in far greater numbers, in particular in the south-west, the high-risk area, so that is where we are focusing our attention at the moment.
The hon. Member for Caithness, Sutherland and Easter Ross asked us to learn lessons from other parts of the UK. As I pointed out in his debate on badger culling and bovine TB, Scotland is officially TB-free, but Scotland has an incredibly low badger population. It is the only part of the UK not to have a large badger population.
In Northern Ireland, which was mentioned, the approach is to trap, test, and vaccinate or remove. We follow the evidence from that approach closely, but the difficulty is that there are no good diagnostics for picking up the disease, as I said earlier. The people in Northern Ireland might therefore release up to 40% of badgers that have the disease, although they would not have detected it. In addition, they could be vaccinating and re-releasing badgers that had already had the disease. That approach is by no means perfect, even though superficially it sounds logical.
The shadow Minister, the hon. Member for Workington (Sue Hayman), mentioned costs. All I can say is that in year 1, the costs were higher—a huge amount of surveillance and post-mortem testing was going on, we had the independent expert panel and policing costs were higher—but the costs have been reducing as we have rolled out the cull. We also have to put that in context: every year, the disease is costing us £100 million, so doing nothing is not an option.
