While some animal rights activists have long accepted that there is a link between bovine tuberculosis (TB in cattle) and badgers, others have argued that it was not proven. They felt that the culling of badgers to stop the spread of TB in cattle was not justified if a link was unproven. But direct evidence of the transmission of TB between badgers and cattle has now been found. DNA sequencing of the TB bacteria in cattle and in badgers has shown that the disease crosses species barriers. This latest discovery completely undermines the case of those who have opposed badger culling. To protect farmers from severe loss of their cattle and hence their livelihoods – and to protect one of our primary sources of meat and milk – the badger population should be culled.
