Interpretive summary: Application of soil amendments of animal origin (for example, manure) to agricultural land used for crop production has been a long-standing practice to maintain or improve soil quality through addition of organic matter, nitrogen, and phosphorus. However, fresh, untreated manure and related amendments can contain pathogens that may survive for extended periods after application to agricultural land. The presence of these pathogens will increase the risk of contaminating the crops that are grown in the amended soil. Additional studies are needed to enhance our understanding of preharvest microbial food safety hazards and control measures that pertain to the application of untreated soil amendments of animal origin to land used to grow produce that may be consumed raw. This document is intended to provide a framework for such studies by defining the scope and type of data required and by providing an approach to study design. This document also serves as a tool for evaluating the strength of existing data, and thus can aid the produce industry and regulatory authorities in identifying research needs. Ultimately, use of this framework by researchers provides a means to increase consistency among and between research studies, and facilitates the direct comparison of hazards and the effectiveness of hazard controls applied to different regions, conditions, and practices.
