People get things out of proportion. There's a lot of information specifically about badgers and TB here:

We were very successful in reducing the incidence of TB until the late 1970s but instead of pursuing the goal of entirely eradicating the disease we relaxed. I suspect farmers' representatives were successful in lobbying for the removal of many restrictions because it was costing them money, and this has allowed things to get out of hand. Pockets of TB have sprung up all over the place, and it's hard to see the need to point to wildlife as an explanation when potentially diseased cattle are routinely moved in lorries, often hundreds of miles, after being sold.
I'm personally far from convinced that the government have formed their policy purely on the basis of the evidence. Highly promising research on vaccination was abandoned, to my mind inexplicably. The proposed system of local organization for culling badgers is frankly laughable -- think Neighbourhood Watch meets Dad's Army. It's going to get worse before it gets better.
It probably isn't such a news-worthy topic.

Er, did we hijack this thread? Sorry. I like badgers, and I don't see why they should suffer for our mistakes.
