2004-2007年肇庆市食品中食源性致病菌监测与分析

目的了解肇庆市食品中食源性致病菌的污染状况和污染水平,初步确定高危食品的种类,为食源性疾病的监测提供科学的依据。方法按全国食品污染物监测网的工作手册,2004-2007年采集4个监测点的5大类食品(生肉、熟肉、水产品、生吃水产品和生吃蔬菜)共计325份,对沙门菌、单核细胞增生李斯特菌、大肠杆菌O157∶H7和副溶血性弧菌4种食源性致病菌进行监测分析。结果325份食品样品中,检出致病菌27株(8.31%)。其中沙门菌16株(4.92%),单核细胞增生李斯特菌10株(3.08%),大肠杆菌O157∶H7未检出,80份水产品中检出副溶血性弧菌1株(1.25%)。生肉的污染情况最为严重,检出率为11.35%,其次是熟肉,检出率为9.68%;水产品的检出率为5.45%,生食水产品的检出率为4.00%,生食蔬菜的检出率为2.56%。结论沙门菌和单核细胞增生李斯特菌对肇庆市食品的污染普遍存在。生肉、熟肉的污染尤为严重,是重要的高危食品。
