The aim of this work was to assess the microbiological safety and quality of horsemeat. A total of 19 fresh horsemeat samples were analysed. Mesophile counts were 4.89 ± 1.08 log CFU/g, and , spp., and enterococci were only isolated from 36.84%, 21.05%, and 15.79% of the samples, respectively. Neither nor were found in any sample. spp. and were detected in 31.58% and 21.05% of the samples, respectively. was not detected in any sample. The dominant bacteria were lactic acid bacteria. Seven different spp. were identified, the most common being , , and . showed resistance against mupirocin and cefoxitin. All the strains showed resistance against ampicillin, cefotaxime, and oxacillin. Multi-resistant , , and strains were found, with resistance to 11, 7, and 8 antibiotics, respectively, causing significant concern. Therefore, specific actions should be taken to decrease the contamination of horsemeat.
这项工作的目的是评估马肉的微生物安全性和质量。共分析了19份新鲜马肉样本。嗜温菌计数为4.89±1.08 log CFU/g，并且，分别仅从36.84%、21.05%和15.79%的样本中分离出、和肠球菌。任何样本中均未发现和。分别在31.58%和21.05%的样本中检测到和。任何样本中均未检测到。优势菌为乳酸菌。鉴定出7种不同的，最常见的是、和。对莫匹罗星和头孢西丁表现出耐药性。所有菌株对氨苄西林、头孢噻肟和苯唑西林均表现出耐药性。发现了多重耐药的、和菌株，分别对11种、7种和8种抗生素耐药，令人严重担忧。因此，应采取具体行动减少马肉的污染。
