A total of 11 fresh goat legs were collected at the retail level. Mesophiles, spp., , , , spp., and counts were determined. Nine samples were free of antibiotic residues, while in the other two samples the presence of sulfadiazine and doxycycline was detected. The antimicrobial resistance of , , spp., and isolates was also evaluated. was found in two samples. Methicillin-resistant was detected in one sample. isolated from one sample containing doxycycline residues showed resistance to mupirocin. Moreover, multi-resistant and were found. Most of the isolated were multi-resistant. Neither extended-spectrum β-lactamase -producing nor vancomycin-resistant enterococci were detected in any sample. The presence of doxycycline or sulfadiazine could affect the goat meat microbiota since less microbial diversity was found in these samples compared to those free of antibiotics. The presence of antibiotic residues could increase the antimicrobial resistance of in fresh goat meat. The presence of multidrug-resistant bacteria in goat meat could be considered a potential threat and should be monitored. Special measures should be taken at the farm level and during slaughter to reduce antimicrobial resistance.
共收集了11条零售层面的新鲜山羊腿。测定了嗜温菌、 属、 、 、 、 属以及 的数量。9个样本未检出抗生素残留，而在另外两个样本中检测到了磺胺嘧啶和强力霉素。还评估了 、 、 属以及 分离株的抗菌耐药性。在两个样本中发现了 。在一个样本中检测到耐甲氧西林 。从一个含有强力霉素残留的样本中分离出的 对莫匹罗星耐药。此外，还发现了多重耐药的 和 。大多数分离出的 具有多重耐药性。在任何样本中均未检测到产超广谱β-内酰胺酶的 或耐万古霉素肠球菌。与无抗生素的样本相比，这些含有强力霉素或磺胺嘧啶的样本中微生物多样性较低，因此强力霉素或磺胺嘧啶的存在可能会影响山羊肉的微生物群。抗生素残留的存在可能会增加新鲜山羊肉中 的抗菌耐药性。山羊肉中多重耐药菌的存在可被视为一种潜在威胁，应予以监测。应在农场层面和屠宰过程中采取特别措施以降低抗菌耐药性。
