Abstract:The presence of Escarichia coli in animal manures and strict requirements for use in crop production emphasizes the need for viable treatment methods. The purpose of this study is to determine the efficacy of vermicomposting to suppress E. coli and total coliforms, from hog and horse manure that is either pre-composted or directly fed to Eisenia fetida, and to determine if there are significant differences among these methods. Using a general linear model this study analyzed the occurrence of E. coli and total coliforms in hog and horse manure that was subjected to thermophilic composting prior to vermicomposting and direct vermicomposting for 90 days. The occurrence of E. coli and total coliforms in hog and horse manure were non-detectable after vermicomposting for 90 days. This study definitively states that vermicomposting is an effective way to treat hog and horse manure for the use in crop production. Further research on the mechanisms behind suppression of E. coli would be beneficial to manure management.
