The application of agricultural biosolids to land is likely to increase on farms as pressures intensify to manage nutrients and carbon, especially with regard to slurry. Although much work has been carried out in this area, it has tended to focus on specific aspects of the application‐use cycle, without a coherent framework and notably the role of soil biology has been little studied in this context, or considered appropriately in the development and application of slurry management systems. In this review article we present a hypothesis that the configuration of the soil microbial community is determined by the history of long‐term inputs to which the community has been subjected and that the resultant configuration determines the instantaneous responses of the associated soil to the presence of slurries, and posit a set of critical questions which would effectively test this.

“…However, anaerobic treatments of manure might be less efficient than aerobic treatments in inactivating pathogens, as illustrated, for instance, by E. coli and Salmonella that survived better in anaerobic than in aerobic manure (Semenov et al, 2011). In addition, the efficacy of anaerobic digestion to eliminate zoonotic pathogens depends on the technology used, on the treatment of the digestion end products and on the nature of the pathogen (Burton, 2009;Martens and Bohm, 2009). The choice of the technology interacts with other factors such as the density of animal farms and the scale of the treatment plant (Pantaleo et al, 2013), and the fertilizer value expected for the digestion end-products (Möller and Muller, 2012).…”

“…It can also increase soil carbon sequestration thereby reducing green-house gas emissions (Ryals et al, 2014). Treatments to inactivate microbial pathogens, such as thermophilic composting, can be a way to resolve the compromise between the benefits of using manure for production of fresh produce and the risks for consumer safety (Burton, 2009;Martens and Bohm, 2009). Simple ageing of manure or animal slurries without proper control of its temperature does not provide a reliable reduction of human pathogens (Berry et al, 2013).…”

(2016). Agrifood systems and the microbial safety of fresh produce: trade-offs in the wake of increased sustainability.Science of the Total Environment, 562, 751-759. H I G H L I G H T S• Measures taken to improve safety were assessed for their impact on sustainability.• Fresh produce safety improvements may come at the expense of sustainability.• Environment, food security and human health constituted the three domains of sustainability.• Measures to improve safety should be adapted to each agrifood system. Fresh produce has been a growing cause of food borne outbreaks world-wide prompting the need for safer production practices. Yet fresh produce agrifood systems are diverse and under constraints for more sustainability. We analyze how measures taken to guarantee safety interact with other objectives for sustainability, in light of the diversity of fresh produce agrifood systems. The review is based on the publications at the interface between fresh produce safety and sustainability, with sustainability defined by low environmental impacts, food and nutrition security and healthy life. The paths for more sustainable fresh produce are diverse. They include an increased use of ecosystem services to e.g. favor predators of pests, or to reduce impact of floods, to reduce soil erosion, or to purify run-off waters. In contrast, they also include production systems isolated from the environment. From a socio-economical view, sustainability may imply maintaining small tenures with a higher risk of pathogen contamination. We analyzed the consequences for produce safety by focusing on risks of contamination by water, soil, environment and live stocks. Climate change may increase the constraints and recent knowledge on interactions between produce and human pathogens may bring new solutions. Existing technologies may suffice to resolve some conflicts between ensuring safety of fresh produce and moving towards more sustainability. However, socio-economic constraints of some agri-food systems may prevent their implementation. In addition, current strategies to preserve produce safety are not adapted to systems relying on ecological principles and knowledge is lacking to develop the new risk management approaches that would be needed.

“…One of the controversies accompanying the production of food animals is the environmentally sound use of animal waste (Burton, 2009). The US Environmental Protection Agency (EPA) estimates that animals produce three times as much raw sewage as humans by weight (EPA, 2003;7080).…”

Regulating the land application of manure from animal production facilities in the USA

Water pollution from the land application of manure has been cited as an issue that needs to be addressed. Judicial challenges have forced the US Environmental Protection Agency (EPA) to adopt additional controls govemitig concentrated animal feeditig operations (CAFOs). State agencies have also been directed to do more to minimize the risk of pollution from animal production. In developing appropriate controls, regulatory agencies have distinguished animal production facilities based on size and on whether they discharge pollutants into waters of the United States. Four categories of animal producers have been identified based on different requirements addressing the land application of manure. The expenses of regulatory requirements for agriculture suggest that other avenues should be explored to enhance sustainable production and reduce water pollution. The identification of polluters, implementation efforts, enforcement issues and educational endeavors could be augmented to address contamination problems. Finding ways for agricultural groups to cooperate with the EPA and for states to implement total maximum daily load requirements might also be effective in improving water quality. To address the land application of manure, the goal should be to eliminate substandard land application practices that cause too many pollutants to enter surface waters rather than simply imposing additional regulations.
