2015~2018年玉溪市售肉及肉制品细菌性污染状况调查
目的 调查2015~2018年玉溪市售肉及肉制品的细菌性污染状况。方法 采用国家标准方法对161份2015~2018年玉溪市售肉及肉制品进行细菌总数、大肠埃希氏菌、致泻大肠埃希氏菌、金黄色葡萄球菌、沙门氏菌、单核细胞增生李斯特氏菌、空肠弯曲菌、小肠结肠炎耶尔森氏菌及产气荚膜梭菌检测分析。结果 本次调查的161件肉及肉制品中, 单核细胞增生李斯特氏菌、沙门氏菌、金黄色葡萄球菌和空肠弯曲菌的总检出率依次为2.91%、9.68%、7.14%和5.22%; 冷却肉类生肉制品的致病菌检出率最高(37.04%), 与其他肉类制品的检出率间有显著性差异(P0.05); 食源性致病菌中金黄色葡萄球菌超标率最高(28.57%); 城市肉类样品检出率略高于农村; 致病菌在流通环节的总检出率高于餐饮服务环节, 其差异均无统计学意义(P>0.05); 研究中的6种动物性肉类样品的细菌性污染状况不一, 其检出率间存在显著性差异(P＜0.05)。结论 2015~2018年玉溪市售肉类制品中细菌性污染较为严重, 应进一步加强相关产品的全过程监管。
Objective To investigate the bacterial contamination conditions of meat and meat products sold in Yuxi city from 2015 to 2018. Methods The total bacteria, Escherichia coli, diarrhea Escherichia coli, Staphylococcus aureus, Salmonella, and Listeria monocytogenes, Campylobacter jejuni, Yersinia enterocolitica and Clostridium perfringens of 161 samples of meat and meat products sold in Yuxi city from 2015 to 2018 were detected and analyzed by national standard method. Results The detection rates of Listeria monocytogenes, Salmonella, Staphylococcus aureus and Campylobacter jejuni in 161 pieces of meat products surveyed in Yuxi were 2.91%, 9.68%, 7.14% and 5.22%, respectively. The highest detection rate of pathogenic bacteria was found in chilled raw meat products (37.04%), which was significant difference between the detection rate and that of other meat species (P0.05). Staphylococcus aureus had the highest over-standard rate among food-borne pathogens (28.57%). City meat samples detection rate was slightly higher than the countryside, pathogenic bacteria in the circulation of the total detection rate was higher than that of catering and service industry, and their differences had no statistical significance (P>0.05). Bacterial contamination status of 6 animal meat samples in the study was different, with significant difference in detection rate (P<0.05). Conclusion The bacterial contamination of meat products sold in Yuxi city in 2015~2018 is more serious, and the whole process supervision of related products should be further strengthened.
