We investigated the prevalence of Campylobacter jejuni, Campylobacter coli, Salmonella, enterohemorrhagic Escherichia coli, enterotoxigenic Escherichia coli, Yersinia enterocolitica, and Escherichia albertii in domestic chicken and pork sold at retail stores in Saitama Prefecture, Japan. Campylobacter was detected in 35.7% (60/168) of chicken samples and 7.3% (14/190) of pork samples. C. jejuni and C. coli were predominant in chicken and pork, respectively. Salmonella was found in 58.1% (100/172) of chicken samples and 19.9% (41/206) of pork samples. Moreover, Salmonella Schwarzengrund was the major serovar observed in chicken isolates, whereas S. Typhimurium monophasic variant was in pork isolates. Furthermore, ETEC was found in 0.6% (1/160) of chicken samples and 2.4% (5/206) of pork samples. Y. enterocolitica was absent from all (83/83) chicken samples but was present in 9.3% (18/193) of pork samples, with a prevalence in pork tongues as high as 21.0% (13/62 samples). However, EHEC and E. albertii were not detected in our study. Therefore, the results of this study indicate that chicken was highly contaminated with Campylobacter sp. and Salmonella, and pork was with Y. enterocolitica serotype O3, Campylobacter sp., Salmonella, and ETEC.
我们调查了日本埼玉县零售商店销售的家鸡和猪肉中，空肠弯曲菌、结肠弯曲菌、沙门氏菌、肠出血性大肠杆菌、产肠毒素大肠杆菌、小肠结肠炎耶尔森菌和阿尔伯蒂大肠杆菌的流行情况。在168份鸡肉样本中，35.7%（60/168）检测到弯曲菌，在190份猪肉样本中，7.3%（14/190）检测到弯曲菌。空肠弯曲菌和结肠弯曲菌分别在家鸡和猪肉中占主导地位。在172份鸡肉样本中，58.1%（100/172）检测到沙门氏菌，在206份猪肉样本中，19.9%（41/206）检测到沙门氏菌。此外，施瓦岑格伦德沙门氏菌是鸡肉分离株中观察到的主要血清型，而单相变异鼠伤寒沙门氏菌则存在于猪肉分离株中。此外，在160份鸡肉样本中，0.6%（1/160）检测到产肠毒素大肠杆菌，在206份猪肉样本中，2.4%（5/206）检测到产肠毒素大肠杆菌。所有83份鸡肉样本中均未检测到小肠结肠炎耶尔森菌，但在193份猪肉样本中，9.3%（18/193）检测到该菌，在猪舌中的流行率高达21.0%（13/62份样本）。然而，在我们的研究中未检测到肠出血性大肠杆菌和阿尔伯蒂大肠杆菌。因此，本研究结果表明，鸡肉受到弯曲菌属和沙门氏菌的高度污染，猪肉受到O3型小肠结肠炎耶尔森菌、弯曲菌属、沙门氏菌和产肠毒素大肠杆菌的污染。
