Fate of Manure-Borne Pathogens during Anaerobic Digestion and Solids Separation.

ABSTRACT: Anaerobic digestion can inactivate zoonotic pathogens present in cattle manure, which reduces transmission of these pathogens from farms to humans through the environment. However, the variability of inactivation across farms and over time is unknown because most studies have examined pathogen inactivation under ideal laboratory conditions or have focused on only one or two full-scale digesters at a time. In contrast, we sampled seven full-scale digesters treating cattle manure in Wisconsin for 9 mo on a biweekly basis ( = 118 pairs of influent and effluent samples) and used real-time quantitative polymerase chain reaction to analyze these samples for 19 different microbial genetic markers. Overall, inactivation of pathogens and fecal indicators was highly variable. When aggregated across
