Research Project: Monitoring of Antibiotic Resistant Bacteria at Cattle Feedlots

Location: Meat Safety & Quality Research

Project Number: 5438-42000-015-10
Project Type: Specific Cooperative Agreement

Start Date: Sep 01, 2013
End Date: May 31, 2014

Objective:
Determine the variability in antibiotic-resistant Escherichia coli and Salmonella enterica within and among cattle feeding operations.

Approach:
Up to 10 Nebraska feedlots will be visited twice. During each visit fecal swabs and hide sponge samples will be obtained from 42 animals. Also during each visit 12 samples of pen surface soils will be obtained. These samples will be delivered to the U.S. Meat Animal Research Center (USMARC) for enumeration, isolation, and characterization of resistant Escherichia coli and Salmonella enterica.
