Abstract

Escherichia coli O157:H7 appears ubiquitous to pens of feedlot cattle; however, the percentage of cattle shedding the organism within different feedlot pens has been observed to vary widely over time and space.1 The objective of this study was to describe the variability of E. coli O157:H7 fecal shedding within contiguous pens of cattle over the course of the feeding period.
