Abstract
This paper asks what influences farmers' adherence to national and international zoonotic disease intervention efforts and argues that development and promotion of biosecurity interventions must take into account the economic and social context informing how livestock sectors operate and how those who work in them are making a living. Specifically, we explore how poultry farms in Viet Nam are managed amidst global efforts to combat disease and national ambitions to sustain growth. The growth of Viet Nam's livestock sector has been accompanied by a range of disease outbreaks that have caused the deaths of animals and humans, threatened businesses, and led to the introduction and ongoing revisions to biosecurity efforts. Despite a strict national (and international) agenda focusing on disease control through biosecurity strategies, on farms disease management is implemented in various ways and to varying degrees. Based on fieldwork in three provinces of Northern Viet Nam and in-depth interviews with actors working on farms and across the commercial poultry sector, we reflect on social, financial and political factors shaping the country's biosecurity narratives and discuss key practices farming households engage in that influence their disease management efforts. Our findings reveal that strict adherence to biosecurity guidelines is often practically unfeasible for commercial poultry farming households to implement where zoonotic diseases are not a concern related to bird and human health so much as a potential risk to a household's living, that exists among a range of diverse opportunities and uncertainties shaping farming operations in Viet Nam's changing livestock sector.
