Bedding material link to E.coli confirmed

Veterinary researchers at Ohio State University have found a direct relationship between dairies using sawdust bedding and the survival of Escherichia coli 0157:H7 in the environment. The researchers tested cattle on 20 commercial dairies — 10 using sawdust bedding and 10 using sand bedding. They discovered that animals in sand-bedded herds had a significantly lower prevalence of E. coli 0157:H7 than those in sawdust-bedded herds.
