摘要
目的 分析沧州市市售肉与肉制品中6种常见食源性致病菌的污染情况,了解污染水平,及时发现食源性疾病暴发隐患,为监管部门采取控制措施提供指导依据.方法 2021-2022年,在沧州市随机采集296份市售肉与肉制品,针对6种常见食源性致病菌,依据《国家食品污染和有害因素风险监测工作手册》和现行国家标准进行增菌、分离和鉴定.结果 296份样品中,46份检出致病菌,检出率15.54％,其中生禽肉的检出率最高,为24.67％(19/77);其次为生畜肉21.78％(22/101)、熟肉制品4.24％(5/118).检出食源性致病菌49株,检出率为16.55％(49/296),沙门菌的检出率最高,为6.42％(19/296);其次为单核细胞增生李斯特菌(6.08％,18/296)、致泻大肠埃希菌(3.72％,11/296)、金黄色葡萄球菌(0.34％,1/296);未检出空肠弯曲菌、小肠结肠炎耶尔森菌.结论 2021-2022年沧州市市售肉与肉制品存在一定程度的污染,但相对可控.生畜禽肉比熟肉制品污染严重,应有针对性地加强卫生监督及管理.
Abstract
Objective To analyze the contamination situation of six common foodborne pathogens in meat and meat products sold in Cangzhou City,to understand the pollution level,promptly identify potential outbreaks of foodborne diseases,and provide scientific guidance for regulatory authorities to take control measures.Methods From 2021 to 2022,296 samples of commercially available meat and meat products were randomly collected in Cangzhou City.According to the national standards,6 common foodborne pathogens were enriched,isolated and identified.Results Among the 296 samples,46 were detected positive to pathogenic bacteria,with a total positive rate of 15.54％.The highest positive rate was 24.67％(19/77)for raw poultry meat,followed by 21.78％(22/101)for raw animal meat,and 4.24％(5/118)for cooked meat products.49 strains of foodborne pathogenic bacteria had been isolated,with positive rate of 16.55％(49/296).Salmonella had the highest positive rate of 6.42％(19/296),followed by Listeria monocytogenes[6.08％(18/296)],Escherichia coli causing diarrhea[3.72％(11/296)],Staphylococcus aureus[0.34％(1/296)],while Campylobacter jejuni and Yersinia enterocolitica were not detected positive.Conclusion There was a certain degree of contamination in the meat and meat products sold in Cangzhou City from 2021 to 2022,but it was relatively controllable.The positive rate of pathogenic bacteria in raw livestock and poultry meat was significantly higher,targeted hygiene supervision and management should be strengthened.
