The present study was undertaken to determine the occurrence, distribution and antimicrobial resistance profiles of Salmonella serovars in slaughter beef cattle, slaughterhouse environment and personnel engaged in flaying and evisceration during slaughtering process. A total of 800 samples (each sample type, n = 100) consisting of swabs from hides, slaughterhouse personnel hands at flaying and evisceration, rumen and caecal contents, mesenteric lymph nodes, carcasses and holding pens were collected. Of the total 100 beef cattle examined, 14% were Salmonella positive in caecal content and/or mesenteric lymph nodes. Of the various samples analysed, Salmonella was detected in 31% of hides, 19% of rumen contents, 8% of mesenteric lymph nodes, 6% of caecal contents, 2% of carcass swabs, 9% of palm swabs taken from the hands of personnel in the slaughterhouse during flaying (7%) and evisceration (2%), and in 12% of holding pen swabs. The Salmonella isolates (n = 87) belonged to eight different serovars of which S. Anatum (n = 54) and S. Newport (19) were the major serovars and both serovars were detected in all sample sources except in carcass swabs. Eighteen of the 87 (20.7%) Salmonella serovars consisting of Newport (n = 14), Anatum (n = 3) and Eastbourne (n = 1) were resistant to one or more antimicrobials. Among the antimicrobial resistant Salmonella serovars, S. Newport was multidrug resistant (15.6%) and exhibited resistance to streptomycin, sulphisoxazole and tetracycline.
本研究旨在确定屠宰肉牛、屠宰场环境和屠宰过程中剥皮和去内脏人员中沙门氏菌血清型的发生、分布和抗菌药物耐药谱。共采集了 800 份样本（每种样本类型，n = 100），包括来自皮、剥皮和去内脏人员手部、瘤胃和盲肠内容物、肠系膜淋巴结、胴体和畜栏的拭子。在检查的 100 头肉牛中，14%的盲肠内容物和/或肠系膜淋巴结呈沙门氏菌阳性。在所分析的各种样本中，沙门氏菌在 31%的皮、19%的瘤胃内容物、8%的肠系膜淋巴结、6%的盲肠内容物、2%的胴体拭子、9%的屠宰场人员手部在剥皮（7%）和去内脏（2%）时采集的掌拭子以及 12%的畜栏拭子中检出。分离出的 87 株沙门氏菌属于 8 个不同的血清型，其中肠炎沙门氏菌（n = 54）和纽波特沙门氏菌（n = 19）为主要血清型，除胴体拭子外，所有样本来源均检测到这两种血清型。87 株沙门氏菌中的 18 株（20.7%），包括纽波特（n = 14）、肠炎（n = 3）和东伯恩（n = 1），对一种或多种抗菌药物耐药。在耐药的沙门氏菌血清型中，纽波特沙门氏菌为多药耐药（15.6%），对链霉素、磺胺甲恶唑和四环素耐药。
