This document discusses Bull Boar sausages, a traditional Italian-Swiss sausage made in Australia that is at risk of becoming extinct. It is made of half beef and half pork with a secret recipe. A local butcher is trying to preserve the authentic recipe by selling and promoting the sausages to prevent imitators from threatening its quality. The document also mentions a controversy where a pig was set free from being used in the sausages by an animal rights activist student.
