Yes, Brucellosis was the disease I was worried about. A Texas rancher contracted it last year from a feral hog he butchered and it's no fun to deal with. Recommended now is use of latex gloves, limited contact with reproductive organs, and careful blood cleanup when butchering a hog. Cooked meat is no problem.
Hog hunting is fun for lots of folks, but their dogs end up with bad, often fatal, injuries. Releasing feral hogs, a nonnative and invasive species, into the wild is just wrong. Please remember "the wild" is shrinking every minute and wild creatures have no place to go.
Hogs are omnivores, and chicken would be on the menu if easily caught. I could see hogs breaking into a chicken house more for chicken feed than for chickens. Recently I watched an episode of an investigation of crimes show where a human body was disposed of in a hog pen. Domestic hogs, and no evidence left.
If you have ever driven across a field rooted by hogs, you will know one more reason why ranchers and farmers hate the creatures. And there are lots more reasons.
My grandson killed a young hog night before last with his .243. I told him to leave it lay. There are only two creatures that I would say that about - feral hogs and starlings. Wasting meat is not our way.
