One hundred ninety-three frozen food samples collected in Korea various public bazaars from October 2006 to September 2007. Staphylococci were detected in 21.8% of frozen food samples. Staphylococcus aureus was isolated from 17 (8.8%) samples. Other staphylococci isolates were identified as S. warneri (7.8%), S. epidermidis (2.1%), S. xylosus (1.6%), S. eguorum (1%), and S. vitulinus (0.5%). Additionally, the antimicrobial susceptibility of 42 staphylococcal isolates to ten different antimicrobial agents was determined. The staphylococcal isolates demonstrated antimicrobial resistance to mupirocin (31%) oxacillin (14.3%), gentamicin (9.5%), teicoplanin (7.1%) and ciprofloxacin (7.1%). Most of the staphylococcal isolates showed high-level resistance to mupirocin (MIC(90), >128 microg/mL). Fortunately, most of the isolates were susceptible to vancomycin. The total bacteria and Escherichia coli count were tested to investigate the microbiological quality of frozen foods. From 193 frozen food samples, 43 (22.3%), 34 (17.6%) and 19 (9.8%) samples were shown to be of unacceptable quality due to total bacteria, coliform and E. coli counts, respectively.
从 2006 年 10 月到 2007 年 9 月，在韩国的各种公共市场采集了 193 个冷冻食品样本。在 21.8%的冷冻食品样本中检测到了葡萄球菌。从 17 个（8.8%）样本中分离出了金黄色葡萄球菌。其他葡萄球菌分离株被鉴定为沃氏葡萄球菌（7.8%）、表皮葡萄球菌（2.1%）、木糖葡萄球菌（1.6%）、马胃葡萄球菌（1%）和藤黄微球菌（0.5%）。此外，还测定了 42 株葡萄球菌对十种不同抗菌药物的药敏性。葡萄球菌分离株对莫匹罗星（31%）、苯唑西林（14.3%）、庆大霉素（9.5%）、替考拉宁（7.1%）和环丙沙星（7.1%）表现出抗菌耐药性。大多数葡萄球菌分离株对莫匹罗星表现出高水平耐药性（MIC(90)，>128μg/mL）。幸运的是，大多数分离株对万古霉素敏感。测试了总细菌和大肠杆菌的数量，以调查冷冻食品的微生物质量。在 193 个冷冻食品样本中，有 43 个（22.3%）、34 个（17.6%）和 19 个（9.8%）样本因总细菌、大肠菌群和大肠杆菌计数分别而被认为质量不可接受。
