Summary and Implications

Fecal shedding of E. coli O157:H7 was investigated in 140 feeder steers in a corn condensed distiller’s soluble (CCDS) feeding trial at a university field station. Steers were fed diets for differing time periods in pasture and feedlot pen conditions. Individual-animal and composite fecal samples were cultured for E. coli O157:H7 using immunomagnetic bead concentration. None of the fecal samples from steers housed in pens were positive. One of the fecal samples collected from the pastured animals was positive. Inclusion of CCDS in steer diets did not result in higher fecal shedding of E. coli O157:H7 in animals being fed diets containing CCDS over those that were not.
