really pleased to see so many rational opinions on here 
I agree with northern lurker.
However, more needs to be done - much much more
TB testing of cattle needs to be done much more accurately. The percentage that come back as reactors is very high compared to the percentage of cattle that actually do have it. And they put them down, and restrict the farms anyway.
I can think of nothing more devastating than to lose your favourite cow, with no say over it, and then to find out it never had the disease anyway. And nobody thinks it matters because the gov paid you some paltry compensation that probably doesn't cover what it was worth, and even if it's economically fair - you can't replace that cow!
I think more should be being done to sort a viable, safe vaccine for the cattle themselves too.
I am unsure as to whether a badger cull will work tbh. Am aware of some schools of thought as to whether it will spread infected badgers to other areas.
Have no sympathy with protesters though, that purport to be animal lovers, that are happy to let 1000's of cattle die, and infected badgers infect many other animals......as a previous poster said, deer etc - and also domestic pets.
And who want to persecute honest people and landowners who believe they are trying to do the right thing.
