摘要
目的了解汕头市主要食品食源性致病菌污染状况及食源性疾病的发生情况,食品污染来源及其与食源性疾疾病发生的关系,以便能采取相应的预防与控制措施。方法于2004～2006年每年夏秋季在集贸市场、超市采集样品进行致病菌监测,按国标方法对食品中的沙门菌、单核细胞增生李斯特菌、大肠杆菌O157:H7以及海产品中的副溶血性弧菌进行分离和鉴定。结果采集5类样品共251份检出致病菌56份,总检出率为22.31%(56/251),其中,沙门菌检出率为1.99%(5/251),单核细胞增生李斯特菌检出率19.92%(50/251)、大肠杆菌O157:H7检出率为0.40%(1/251),海产品的副溶血性弧菌检出率高达41.93%(13/31)。结论汕头市5类主要食品均受到食源性致病菌不同程度的污染。因此,应加强对各类食品食源性致病菌监测,并采取相应的预防和控制措施,以便防止食源性疾病的暴发。
Objective To characterize understand status of food- borne patheogen contamination and food- borne diseases in Shantou and provide evidence for making control measures. Methods Food samples were collected from marketplace in summer and autumn from 2004 to 2006 and pathogens were detected and identified for the presence of Salmonella spp., Listeria monocytogenes, Escherichia coli O157：H7 and Vibro parahaemolyticus based on the national standard guidelines. Results Totally 56 （22.31% ） patheogens were identified in the 251 foods samples, including 5 （ 1.99 % ） salmonella isolates, 50（ 19.92 % ） Listeria monocytogenes, 1 （0.40%） Escherichia coli O157 ： HT. Out of the 31 seafood samples, 13 （41.93%） V. parahaemolyticus strains were isolated. Conclusion The rate of food contamination with pathogens in Shantou City is high and effective control measures be taken including adopting preventive activity and strengthening monitoring work.
