Results of a longitudinal study of the prevalence of Escherichia coli O157:H7 on cow-calf farms

Abstract

Implementing control strategies for E coli O157:H7 at all levels of the cattle industry will decrease the risk of this organism entering the human food chain. Devising effective on-farm strategies to control E coli O157:H7 in cow-calf herds will require an understanding of the epidemiologic characteristics of this pathogen.
