The Oxford Sandy Black Pig Group have populated an easy to use map of Abattoirs (aka Slaughterhouses) and Butchers in the UK. Each listing has been provided by one of our members so we know they cater for our rare breed OSB pigs.
If you need help with your butchery, these are the experts, but you can find a cutting list to help you here
If you have an Abattoir, Butcher, Slaughterhouse that caters for pigs (swine) that you have used, you can submit a listing here
