【摘要】：目的了解辽宁省各地区市售食品中单核细胞增生李斯特致病菌的污染现状及分布特征,为单核细胞增生李斯特菌的防控工作提供依据。方法辽宁省14个城市全部纳入检测范围,2010—2014年对六类食品进行采样,并对单核细胞增生李斯特菌进行分离和鉴定。结果六类5 822份食品样品中,检出单核细胞增生李斯特菌109株,阳性率为1.87%;其中生畜禽肉阳性检出率为8.88%,水产品为2.02%,熟肉制品为1.22%,速冻米面食品为0.65%,餐饮食品为0.93%,豆制品均为阴性;2010—2014年单增李斯特菌的阳性检出率依次为1.38%、0.67%、1.44%、1.29%、4.82%,年均检出率基本保持平稳;受单核细胞增生李斯特菌污染较为严重的食品为生畜禽肉(8.88%)、水产品(2.02%)、熟肉制品(1.22%)。结论辽宁省各类食品均不同程度受到单核细胞增生李斯特菌污染,尤以生畜禽肉、熟肉制品、水产品污染严重。
[Abstract]:Objective to investigate the contamination status and distribution of Listeria monocytogenes in foods sold in Liaoning Province, and to provide evidence for the prevention and control of Listeria monocytogenes. Methods six kinds of food samples were collected from 14 cities in Liaoning province from 2010 to 2014, and Listeria monocytogenes were isolated and identified. Results 109 strains of Listeria monocytogenes were detected in 5 822 food samples. The positive rate was 8.88 in raw animal meat, 2.02in aquatic products, 1.22in cooked meat products, 0.65 in frozen rice noodle food, 0.93in food for food and beverage, and 1.380.671.441.441.294.82in soybean products, respectively, in 2010-2014, the positive rate of Listeria monocytogenes was 1.380.671.441.294.82.The positive rate was 1.380.671.441.294.82. The average annual detection rate remained stable; The food polluted seriously by Listeria monocytogenes (8.88%), aquatic products (2.02%), cooked meat products (1.22%).
