Abstract: Large-scale movement of animals through trade can spread diseases to places where they arenot endemic. In this paper, we identify the causal effect of global livestock trade on the spread ofinfectious animal diseases through an exogenous increase in the demand for imported livestock. Theinstrumental variable approach exploits an increase in halal livestock imports in Muslim countriesduring Eid-al-Adha to determine the effect of livestock imports on related infections. Using a datasetthat covers 123 countries and five livestock categories in the months between 2004 and 2019, wefind an imports-to-infections elasticity of about 0.75. The relationship is stronger for countries that arelikely to import infected livestock from their partners. There is also evidence that infections spreadthrough interaction between imported livestock, some of which might be infected, and domesticlivestock. These results highlight transmission-through-trade from the origin to the destination.
