Abstract

Cattle are the reservoir for E. coli O157:H7 which is a contaminant of beef products and has been associated with food-borne illnesses in humans. Recently an E. coli O157:H7 SRP® vaccine extract received conditional licensure in the United States for the control of E. coli 0157 in cattle. Cattle are believed to become colonized with E. coli 0157 around the time of birth. The majority of existing research and control strategies attempt to control E.coli 0157 at the feedyard and harvest stages of production. These approaches are addressing the problem post-colonization. The objective of this study was to determine the shedding characteristics and performance of E. coli O157:H7 SRP-vaccinated beef calves born to E. coli O157:H7 SRP-vaccinated dams.
