The objective of this study was to evaluate the microbiological quality and safety of 37 fresh quail meats. Mesophiles, spp., , and staphylococci counts were 5.25 ± 1.14, 3.92 ± 1.17, 3.09 ± 1.02, and 2.80 ± 0.64 log CFU/g, respectively. was detected in seven samples (18.92%). was detected in one sample (2.70%). was not detected in any sample. The dominant bacteria were spp. (30.46%), (19.87%), lactic acid bacteria (14.57%), and (11.92%). and enterococci were isolated to a lesser extent, 7.28% and 1.99%, respectively. The dominant found were (42.53%). ESBL-producing was detected in one sample (2.70%), showing resistance to 16 antibiotics. Sixteen different spp. and three spp. were identified, the most common being (19.86%) and (17.02%). and were also found in one and four samples, respectively. Methicillin-resistant and were found in 13.51% and 10.81% of quail samples, respectively. These bacteria showed an average of 6.20 and 18.50 resistances per strain, respectively. The high resistance observed in ESBL-producing and methicillin-resistant is of special concern. Measures should be adopted to reduce the contamination of quail meat.
本研究的目的是评估37份新鲜鹌鹑肉的微生物质量和安全性。嗜温菌、 spp.、 、和葡萄球菌计数分别为5.25±1.14、3.92±1.17、3.09±1.02和2.80±0.64 log CFU/g。在7个样品（18.92%）中检测到 。在1个样品（2.70%）中检测到 。在任何样品中均未检测到 。优势菌为 spp.（30.46%）、 （19.87%）、乳酸菌（14.57%）和 （11.92%）。 和肠球菌的分离程度较低，分别为7.28%和1.99%。发现的优势 为 （42.53%）。在1个样品（2.70%）中检测到产超广谱β-内酰胺酶（ESBL）的 ，对16种抗生素耐药。鉴定出16种不同的 spp.和3种 spp.，最常见的是 （19.86%）和 （17.02%）。 和 也分别在1个和4个样品中被发现。耐甲氧西林的 和 分别在13.51%和10.81%的鹌鹑样品中被发现。这些细菌每株平均分别有6.20和18.50种耐药性。产ESBL的 和耐甲氧西林的 中观察到的高耐药性尤其令人担忧。应采取措施减少鹌鹑肉的污染。
