Composted Animal Manures: Precautions and Processing

Abstract

Compost is made by recycling organic materials such as yard trimmings, wood chips, food scraps, and animal manures in a controlled process. The process employs microorganisms to transform the raw materials so that they are no longer recognizable. Quality compost is thoroughly decomposed and pathogen-free. The possible presence of pathogenic microorganisms in compost is a major challenge for compost producers. Composted animal manures can be used in many beneficial products, but they must be properly processed. The most important conditions with respect to sanitization are: the composting process must be thorough; the composting process must be complete; and, the finished compost must not be reinoculated with pathogens.
