description Because <i>Enterococcus faecium</i> is an important nosocomial pathogen and sentinel organism for tracking antimicrobial resistance, information on the contamination and antimicrobial resistance patterns of <i>E. faecium</i> in food are essential to public health and food safety. We analyzed the occurrence of <i>E. faecium</i> in retail pork meat products (<i>n</i> = 124), and antimicrobial resistance of 30 <i>E. faecium</i> isolates were examined against 14 antimicrobials using the broth dilution test and disc diffusion test. Rep-PCR-based molecular diversity was also analyzed using Deviersilab. The highest contamination of enterococci was observed for minced pork meat but most of the <i>E. faecium</i> was isolated from meatball-type frozen pork meat products (FP). Incidences of antimicrobial-resistant <i>E. faecium</i> against erythromycin, clindamycin and nitrofurantoin were 80%, 50% and 20%, respectively. No vancomycin-resistant enterococci were analyzed. Rep-PCR showed distinctive clusters with a similarity ≥ 98%, consisting of 18 <i>E. faecium</i> isolates from FP manufactured in seven companies. The analyzed data on the contamination and antimicrobial resistance patterns combined with molecular typing can be useful to derive risk management of antimicrobial-resistant enterococci in food.
