Are humans making animals sick?

New evidence suggests that bacteria/pathogens now pass from humans to animals. In this case, a strain of bacteria has passed from humans to chickens. Tragically, this discovery means it's possible that animals could make humans sick. Combine this factor with the globalized production and distribution of animals for human consumption, and we've got a big, huge mess on our hands. And still, we're not addressing the root of the problem.
