I know we all like to blame everything on DEFRA but this time I think we may be a bit wide of the mark.
Most of what we castigate DEFRA for regarding Bluetongue should really be laid at the door or the EU Agriculture Commission. In the first place, the EU laid down the guidelines under which the Bluetongue Control Strategy would operate. Each country had to come up with a strategy which suited it's own situation, but these had to be agreed with the Commission. The very fact that Bluetongue is a Notifiable Disease is a Commission decision, so any change in its status is not in the power of DEFRA, it can only influence but not determine.
One thing we all know about DEFRA is that they are pretty useless at communication. On the one hand Hilary Benn is quoted as saying that farmers will be allowed to purchase vaccine from a bank - the implication being that there will be no official vaccination programme. On the other hand, the feedback from industry stakeholders is that discussions are ongoing about an official vaccination programme in the Protection Zone (formerly Control Zone).
Perhaps what is envisaged is a formal policy in the PZ with farmers in the SZ allowed to buy vaccine if they wish. I don't know, any more than I know why Benn hasn't bothered to pick up on the confusion and clarify their intentions.
With regard to the burden of cost of the disease, whether caused by infected animals or by movement restrictions, yes, DEFRA are clear, it is an industry economic problem and we are on our own. This is no different from any other disease caused losses so what do we expect?
