E. coli prevalent in cattle fed distiller's grain

Researchers have found that there was a prevalence of E. coli bacteria found in the manure of cattle fed dried distillers grains.

The study released by the Kansas State University in the U.S. found that cattle fed dried distillers grain, a by-product of ethanol production, had a higher prevalence of E. coli. Some strains of E. coli can cause food poisoning in humans.

Researchers from the University of Nebraska-Lincoln (UNL), who have been researching ways to reduce E. coli, are surprised by the KSU results. Similar testing they have performed found no increase in E. coli from feeding dried distillers grains.

UNL animal science professor, Terry Klopfenstein, says while they respect KSU's research, it is puzzling.

KSU's findings shouldn't affect cattle feeders use of dried distiller's grains according to T.G. Nagaraja, a professor of diagnostic medicine and pathobiology at Kansas State's College of Veterinary Medicine

E. coli is present in all cattle, and he says research should focus on finding the reasons for the increase in E. coli with dried distiller's grain and work to find a way to change it.
