Swine mortality, particularly those caused by infectious pathogens, poses biosecurity risks and causes significant economic impact. Dead handling structures may act as sources of viral environmental contamination, but limited attention has been given to their role in biocontainment and bioexclusion of pathogens in and around farms. In this study, we tried to diminish this problem by assessing the environmental contamination around dead animal disposal structures in wean-to-finish farms and determining if the contamination levels differ according to how dead animals are managed.
