Recognition as a spe- cialist by the Royal Vet- erinary College followed.
John’s specialty in pig medicine was registered by the Veterinary Sur- geons Board of Queens- land and is recognised nationally and in New Zealand.
In response to a ques- tion about antimicrobial medicines and pork pro- duction John wrote, “The health of the human race is largely determined by the production of healthy food.”
