Will someone please explain to me how it was that in the 1950's, when the badger population was much lower than it is now - because we hunted them - we were able, using the same tests as today, to eliminate TB from the UK cattle herd? It took us a few years of regular testing and a lot of infected cattle were slaughtered. But government, vets and farmers working together achieved it. And a disease that had been the scourge of humans as well as cattle (because not all milk was pasteurised then and people caught TB from drinking it) disappeared from our shores.
So, I ask again - if fewer badgers enabled the elimination of cattle TB then, why wouldn't it do the same today?
