“…In a second study with 0 and 25% WDGS (14), a significant difference with individual animals samples was observed only on I of 2 sampling days. In contrast to the above studies (13,14), data reported by Peterson et al (21) indicated that WDGS in cattle diets at levels of 0 to 5017v had no effect on the probability of finding E. co/i 0157:H7 in feces, but dietary levels of 20 and 30% WDGS were associated with fewer E. coli 0157: H7 at the terminal rectum relative to 0% WDGS in the diet. These authors did not observe significantly higher probabilities for E. coli 0157:H7 at the terminal rectum with 40 and 50% WDGS diets as compared with a 0% WDGS diet, but the authors did report large variations with these diets.…”

The objective of this study was to determine if wet distillers grains with solubles (WDGS) from corn in diets affected Escherichia coli O157:H7 in growing and finishing cattle; steers (n = 603) were randomly assigned to diets with or without WDGS. Hide and fecal samples were collected monthly (October through June) from each animal for enumeration and enrichment of E. coli O157:H7. In the growing phase (0 or 13.9% WDGS diets), fecal prevalence for E. coli O157:H7 in steers fed a diet with WDGS was twice that of the prevalence in control steers (P < 0.001). In the finishing phase (0 or 40% WDGS diets), the average prevalence in feces (P < 0.001) and on hides (P < 0.001) was higher for cattle fed WDGS. The average percentage of fecal E. coli O157:H7 enumerable samples during the finishing phase for cattle fed WDGS was 2.7% compared with 0.1% for control steers (P < 0.001). The average percentage of E. coli O157:H7 enumerable hide samples was not different between diets, but the cattle fed WDGS had higher levels (P < 0.05) of the pathogen. Animals fed WDGS had higher levels of E. coli (P < 0.001), higher pH values (P < 0.001), and lower concentrations of L-lactate (P < 0.001) in feces than those values of the control steers. These results indicate that feeding 40% WDGS could increase the level and prevalence of E. coli O157:H7 in and on feedlot cattle when E. coli O157:H7 is seasonally low.
