This document summarizes Dr. Hayley MacGregor's research on the social dimensions of zoonoses (diseases that can be transmitted between animals and humans) in emerging livestock systems. It discusses two key areas: 1) how cultural and social practices influence zoonotic risk, and 2) the relationship between humans and animals. For area 1, it describes how factors like intensification of production, supply chains, processing practices, markets and consumer demand can drive zoonotic risk. For area 2, it discusses how human-animal relations blur traditional categories, and how the health of humans and animals is interdependent.
