摘要： 为了解珠三角地区生猪屠宰场中沙门氏菌、空肠弯曲菌和大肠埃希氏菌O157:H7 3 种食源性致病菌污染情况。该研究采集广州、佛山、东莞、肇庆10家不同规模生猪屠宰场共 1 509份屠宰环境与猪肉样品进行检测分析。检测出大肠埃希氏菌O157:H7阳性样本33份，检出率2.19%；检出空肠弯曲菌阳性样本210份，检出率13.92%；检出沙门氏菌阳性样本322份，检出率21.34%。结果表明珠三角部分地区屠宰场沙门氏菌的污染较为严重，生猪屠宰场空肠弯曲菌普遍存在，大肠埃希氏菌O157:H7污染水平较低；部分屠宰场屠宰环节污染较为严重，存在3种菌共存现象。提示屠宰场需进一步完善屠宰工艺和消毒措施，减少屠宰环境中的致病菌对猪肉胴体的污染，保障肉品安全。

Abstract: In order to investigate the contamination of Salmonella，Campylobacter jejuni and Escherichia coli O157：H7 in pig slaughterhouses across the Pearl River Delta region. A total of 1 509 slaughter environment and pork samples were collected from 10 different scale pig slaughterhouses in Guangzhou，Foshan，Dongguan and Zhaoqing for detection and analysis. 33 positive samples of Escherichia coli O157：H7 were detected，and the detection rate was 2.19%. 210 positive samples of Campylobacter jejuni were detected，with a detection rate of 13.92%. A total of 322 Salmonella positive samples were detected，with a detection rate of 21.34%. The results showed that the pollution of Salmonella in slaughterhouses in some areas of the Pearl River Delta was more serious，Campylobacter jejuni was widely distributed in pig slaughterhouses，and the pollution level of Escherichia coli O157：H7 was low. Some slaughterhouses have serious pollution in the slaughtering process，and there are three kinds of bacteria coexisting. It is suggested that the slaughterhouse should further optimize the slaughter process and disinfection protocols to minimize pathogenic contamination of pork carcasses by pathogenic bacteria in the slaughter environment and ensure the safety of meat.
