Summary
To the Editor: Rates of resistance to various antimicrobial drugs are rapidly increasing in Escherichia coli, in health care settings and in the community. We reported a high prevalence of cephalosporin-resistant E. coli, most of which produced CMY-2 β-lactamase, among retail poultry products in Pittsburgh, Pennsylvania, USA during 2006–2007 [2]. CMY-2 is the most commonly acquired ampicillin C (AmpC)–type β-lactamase found in E. coli that cause human infections [3]. A convenience sampling of 104 raw ground meat products from 3 local grocery stores in Pittsburgh was performed during February–April 2011.
