“…Typically, CAFOs use full containment systems, such as holding ponds or runoff retention basins, to contain feedlot runoff. Although the focus of the National Pollutant Discharge Elimination System regulatory guidelines is predominantly on the nutrient components of animal manures, it is increasingly being recognized that sustainable manure management involves more than just a focus on nutrients and now includes assessment of zoonotic pathogens and veterinary pharmaceuticals in animal manures (Leytem et al, 2013). Additional regulations apply to recreational surface waters, which are monitored for fecal indicator bacteria, as a proxy for the presence of fecal pathogens, and there are health concerns when contaminated water is used to irrigate or process crops used for food production (Blaustein et al, 2015).…”

Runoff from open-lot animal feeding areas contains microorganisms that may adversely affect human and animal health if not properly managed. One alternative to full manure containment systems is a vegetative treatment system (VTS) that collects runoff in a sediment basin and then applies it to a perennial vegetation (grass) treatment area that is harvested for hay. Little is known regarding the efficacy of large-scale commercial VTSs for the removal of microbial contaminants. In this study, an active, pump-based VTS designed and built for a 1200-head beef cattle feedlot operation was examined to determine the effects of repeated feedlot runoff application on fecal indicator microorganisms and pathogens over shortterm (2 wk) and long-term (3 yr) operations and whether fecal bacteria were infiltrating into deeper soils within the treatment area. In a short-term study, fecal bacteria and pathogen numbers declined over time in soil. Measurements of total coliforms and Enterococcus counts taken on control soils were not effective as fecal indicators. The repeated application of manure-impacted runoff as irrigation water did not enrich the pathogens or fecal indicators in the soil, and no evidence was seen to indicate that pathogens were moving into the deeper soil at this site. These results indicate that large-scale, active VTSs reduce the potential for environmental contamination by manure-associated bacteria. Also, this study has implications to full-containment systems that apply runoff water to land application areas (cropland) and the fate of pathogens in the soils of land application sites.

“…Manures with a low MC, such as chicken litter or dehydrated feces, are normally applied to fields by using a spreader or manure slinger (11,21). Such application methods could allow pathogenic bacteria associated with the manure particles to become aerosolized and transported to downwind locations.…”

“…Previous research has examined the role of dust generated during livestock operations and manure management systems to assess the risks to workers, individuals in nearby communities, animals, and croplands in the vicinity (11,21,24,35). Manures with a low MC, such as chicken litter or dehydrated feces, are normally applied to fields by using a spreader or manure slinger (11,21).…”

“…A substantial body of research has focused on the persistence, spread, and survival of Salmonella enterica and other pathogenic bacteria in manure (18,28) and its subsequent transmission onto fresh produce, especially leafy vegetables due to their large surface area (4,23). Animal manure, when dehydrated, generates dust-like particles that can be small enough to become readily airborne (21,26,31). The handling of manure in agricultural environments (e.g., stacking, storing, application to fields, and transport from animal rearing operations to compost facilities) can lead to the unintentional airborne transfer of foodborne pathogens from the source of the manure to leafy green farms in proximal locations (4).…”

Concerns about the microbiological safety of fresh produce have attracted attention in the past three decades due to multiple foodborne outbreaks. Animal manure contaminated with enteric pathogens has been identified as an important preharvest pathogen source. This study investigated the survival of Salmonella enterica in dust particles of dehydrated turkey manure and how association with manure dust may enhance the survival of salmonellae on leafy greens in the field. The survival of a cocktail of multiple Salmonella serotypes in the dried fecal material of various particle sizes (125 to 500 μm) was examined at varying moisture contents (5, 10, and 15%). Survival times of the pathogen were inversely related to moisture content and particle size of manure dust, with viable Salmonella still detectable for up to 291 days in the smallest particle size (125 μm) with 5% moisture. Association with manure dust particles increased the survival of Salmonella when subjected to UV light both under laboratory conditions and on the surface of spinach leaves in a greenhouse setting. The results of this study suggest that aerosolized manure particles could be a potential vehicle for Salmonella dispersal to leafy greens if the microorganism is present in the dry manure.

The importance of consensus science to managing phosphorus in the environment: SERA‐17 and the legacy of Andrew Sharpley

Phosphorus (P) loss from agricultural systems to surface waters, and ultimately, eutrophication, presents a wicked problem requiring transdisciplinary solutions. The mission of SERA‐17 (Southern Extension and Research Advisory Information Exchange Group‐17) has been to address this problem by developing “Innovative Solutions to Minimize Phosphorus Losses from Agriculture.” Over the course of his career, Dr. Andrew Sharpley demonstrated a rare ability to collaboratively achieve consensus around issues related to the science and management of P. The SERA‐17 organization served as the central community of experts and stakeholders where that consensus was built and applied. The consensus‐based approach, demonstrated by Sharpley and at the core of the SERA‐17 organization, was routinely applied to key areas of P science to produce applied outcomes that have been readily adopted: advance foundational science to resolve knowledge gaps and to promote innovation; promote consistency in methods to facilitate comprehensive investigations and conclusions across a diversity of systems; engage diverse stakeholders to prioritize research, and ultimately, ensure that outcomes reflect a plurality of perspectives; and deliver pragmatic solutions that reflect the best information available at a particular time. We review the history of SERA‐17 in delivering new science and management recommendations for P, with an eye to elucidating Sharpley's role and legacy in this process.

Sustainable manure management.

Abstract: This chapter seeks to elucidate the concerns underlying manure management and the considerations of sustainable manure management. While the chapter provides a broad review of salient issues, particular emphasis is placed upon emerging areas of concern and innovation in manure management.
