Fate of Escherichia coli O157:H7 in manure and amended soil: effects of cattle feeding, manure type and dairy managementEelcoFranzauthorAnne D.van DiepeningenauthorAnna A.VisserauthorWim J.BlokauthorAriena H.C.van BruggenauthorIn the present study, we studied the effect of cattle diet on the survival of E. coli O157:H7 in manure from dairy cattle subjected to 6 different feeding regimes consisting of 3 different roughage types and 2 levels of crude protein concentrates. In addition, the rate of survival of E. coli O157:H7 in manure-amended soil as a function of manure type (manure vs. slurry) and dairy farm management (organic vs. conventional) was determined. The roughage type affected significantly the decline rate of E. coli O157:H7: decline was faster in manures with relative higher pH and fiber content. Decline was faster in slurry compared to manure and in organic slurry compared to conventional slurry. Food security, food quality and human health2005Conference paper, poster, etc.
