We report the recovery of Escherichia coli or Klebsiella pneumoniae containing the extended-spectrum β-lactamase gene blaCTX-M from 24 of 1,495 (1.6%) swine fecal samples in 8 of 50 (16%) finishing barns located in 5 U.S. states. We did not detect an association between antimicrobial use and recovery of blaCTX-M.
