摘要
目的了解酒泉市食品中主要食源性致病菌的污染状况,确定高危食品,为预防和控制食源性疾病提供科学依据[5-6]。方法按照《全国食源性致病菌监测工作手册》的检测技术要求,通过对2010—2012年度酒泉市采集食品样品共1157份的检验分析,对沙门氏菌、单核细胞增生李斯特菌、副溶血性弧菌、金黄色葡萄球菌、阪崎肠杆菌、志贺氏菌、大肠埃希菌O157∶H7对本市食品的污染情况进行监测。结果 1157份样品中,共检出致病菌100株,总检出率为8.64%。致病菌检出率分别为生畜肉16.67%(5/30)、生禽肉33.33%(10/30)、鲜冻水产品17.50%(7/40)、速冻熟制米面制品20.00%(8/40)、熟肉制品6.92%(9/130)、即食非发酵性豆制品14.5%(9/62)、婴幼儿配方食品3.81%(4/105)、冰激凌5.0%(1/20)、凉拌菜10.00%(18/180)、即食地方特色食品6.92%(9/130)、糕点及饼干1.25%(1/80)、熟制米面制品1.00%(1/100)、生奶22.50%(18/80)。即食蛋制品、生食果蔬菜、鲜榨果蔬汁中未检出致病菌。结论生肉、生奶和水产品是酒泉市食品的主要污染品种,作为直接入口食品的即食非发酵豆制品、凉拌菜、地方小吃、熟肉制品,可能导致较高的食源性疾病风险。
Objective To investigate and identify the contamination of main foodborne pathogenic bacteria and the kind of high-risk foods and to provide scientific basis for prevention and control of foodborne diseases in jiuquan. Methods Based on the standard operation procedures in the handbook of National Surveillance on Foodborne PathogenicBacteria, 1157 food samples in jiuquan from 2010 to 2012 were collected and analyzed for the occurrence of Salmonella, Listeria monocytogenes, Vibrio parahaemolyticus, Vibrio vulnificus, Staphylococcus aureus, Bacillus cereus, Enterobacter sakazakii, Shigella sonnei and Escherichia coli O157:H7 in foods. Results The 1157 food samples tested, 100 pathogenic strains were isolated, detective rate was 14.19%, including raw meat16.67% (5/30), Raw poultry 33.33% (10/30), Fresh and frozen aquatic productsl7.50% (7/40), Frozen cooked rice products17.5% (7/40), The cooked meat products 6.92% (9/130), Instant non-fermented bean products14.5% (9/62), Infant formula food44.76% (47/105), ice cream5.0% (1/20), vegetable saladl0.00% (18/180), The instant the local characteristic food10.77% (14/130), Cakes and biscuitsl.25% (1/80), Cooked rice products 29.00% (29/100), rice dumpling5% ( 1/20), raw milk22.50% (18/80). Foodborne Bacterias were n' t detected in Instant egg products, Fresh fruit and vegetables, The fresh fruit and vegetable juice. Conclusion Raw meat, raw milk and aquatic food products are the main kinds of food contaminated by foodbornepathogens in jiuquan. As the ready-to-eat food, such as Instant non-fermented bean products, Local snacks, vegetable salad, cooked meat are at higher risks for causing foodborne diseases.
