Frequent occurrence of extended-spectrum beta-lactamase- and transferable AMPC beta-lactamase-producing Escherichia coli on domestic chicken meat in Sweden

Abstract

Forty-four percent of Swedish chicken meat fillets were contaminated with extended-spectrum or transferable AmpC beta-lactamase- producing Escherichia coli strains. Isolates from Swedish chicken meat and broilers were closely related to isolates from chicken meat imported into Sweden; these results indicate a common source of the contamination. © 2013, American Society for Microbiology.
