Minimizing Potential Human Health Risks in Hog Farming
The majority of swine confinement buildings are fully enclosed but without control (other than ventilation) technology to reduce or regulate airborne dusts, gases and microorganisms. In winter the barn’s comfortable temperature is maintained by reducing ventilation and the intake of exterior cold air. This increases the levels of respirable indoor environmental contamination (dust, swine dander, fungi, bacteria, and gases).
