Abstract

Livestock are known contributors to stream pollution. Numbers of fecal streptococci and Escherichia coli in
manure naturally deposited by livestock in the field are needed for activities related to bacterial source tracking and determining
maximum daily bacterial loading of streams. We measured populations of fecal streptococci and E. coli in
fresh and dry manure from cattle (Bos taurus L.), horses (Equus caballus L.), and sheep (Ovis aires L.) on farms in
southern Idaho. Populations of indicator bacteria in dry manure were often as high as that in fresh manure from horse
and sheep. There was a 2 log 10 drop in the population of fecal coliform numbers in dry cattle manure from cattle in
pastures but not from cattle in pens. Bacterial isolates used in source tracking should include isolates from both fresh
and dry manure to better represent the bacterial source loading of streams.
