摘要
目的了解肉鸡孵化、养殖、屠宰加工和配送分销各环节的沙门菌污染状况,确定易受污染的环节和样品类别,为预防和控制由沙门菌引起的食源性疾病提供科学依据。方法按照随机抽样的原则,在济南市肉鸡孵化场、养殖场、屠宰场(点)和配送分销点设置16个监测点,按不同的季节和环节定期随机采集监测样本。检验方法按照《2012年全国食源性致病菌监测工作手册》执行。结果监测17种样品共1 204份,13种样品检出沙门菌202株,总检出率为16.78%。除1种不可分型外,其他分属4群28种血清型,以印第安纳血清型沙门菌最多(37.13%);4个环节中,以屠宰加工环节沙门菌检出率最高(23.14%);四个季度中,以第二季度沙门菌检出率最高(21.74%);17种样品中,以屠宰环节的褪毛后整禽样本沙门菌检出率最高(42.19%)。结论济南市肉鸡相关行业的沙门菌交叉污染严重,应加强肉鸡生产链全过程的监管和监测,并针对各污染环节和工序,确定不同的关键控制点,制定相应的操作程序,以减少沙门菌的交叉污染。
Objective To understand the condition of Salmonella contamination in broilers through the production chain of hatching,breeding,slaughtering,processing and distribution,determine the vulnerable point and sample category,and to provide a scientific basis for the prevention and control of food-borne diseases caused by Salmonella.Methods Sixteen monitoring points including broiler hatcheries,farms,slaughterhouses and markets were set up to collect samples with random sampling method.The Salmonella were detected based on the handbook of National Surveillance on Food-borne Pathogenic Bacteria of 2012.Results In 2012,1204 samples of 17 kinds were detected.202 strains of Salmonella were isolated from 13 kinds of samples with an overall detection rate of 16.78%.The salmonella were classified into 4 groups and 28 serum types with 1 exception.Indiana serotype were most prevalent and accounted for 37.13%.The detection rate was the highest in slaughtering process,the second quarter of the year,and broilers after deplumation,with detection rate 23.14%,21.74% and 42.19%,respectively.Conclusion The cross-contamination of Salmonella was serious in broilers industry in Jinan.The supervision and monitoring should be strengthened through the whole process.In order to reduce the level of Salmonella cross-contamination,the critical control points should be determined and corresponding operating procedures should be formulated.
