Soil amendments, particularly those of biological origin like manure and compost, are addressed in the Produce Safety Alliance training because they can introduce harmful pathogens if not properly managed. Treated soil amendments, such as composted manure, are safer and can be applied closer to harvest time than raw manure because it requires longer intervals before planting or harvest to reduce contamination risks. Proper composting involves monitoring and maintaining specific temperatures and turning frequencies to kill pathogens. Farmers should ensure untreated amendments are stored and handled in ways that prevent contamination of fields, equipment and produce. Recordkeeping of application dates, treatment methods, and storage practices is essential to support compliance and enhance food safety.
