福建省2000年～2002年食品中沙门氏菌的监测与分析

Situation of food Contamination Salmonella in Fujian from 2000 to 2002

为了解福建省食品中沙门氏菌的污染状况、分布特征以及耐药情况和噬菌体类别 ,为评价和预警我省食品污染状况 ,为制定相关食品卫生政策提供可靠的基础数据 ,根据福建省的不同地理位置和经济状况 ,选择福州、泉州、龙岩和尤溪 4个市县为监测点 ,在夏季和冬季随机采集农贸市场的样品。增菌后 ,采用沙门氏菌显色平板分离 ,经VITEK生化试验和血清学鉴定后进行噬菌体分型和药敏试验。 2 0 0 0年冬～ 2 0 0 2年夏共检测 978份食品 ,沙门氏菌的总检出率为 6 4 4% ,分属 5个群 ,13个血清型 ,噬菌体型别分散 ,耐药株占 2 9 6 9%。实验显示福建省生 (冻 )畜禽肉、生食水产品、蛋中存在着不同程度的沙门氏菌污染 ,应加强畜、禽类屠宰、运输、加工过程的卫生管理和监测 ,并规范抗生素的管理和使用 ,减少食源性疾病的发生。

To understand the situation of salmonella contamination in food products in Fujian,its distribution features and antibiotics susceptibility of the isolates and to provide needed information to policy makers to work out relevant regulations and construct food product safety alarming system,4 sentinel surveillance spots (Fuzhou, Quanzhou, Longyan, and Youxi) have been chosen according to their geographic locations and their economic background. They are responsible for randomly collecting food products from markets in winter and summer seasons from 2000 through 2002.Then the collected samples would be processed and inoculated in salmonella agar plates.After that,the isolates would go through biochemistry testing,serotyping and antibiotics susceptibility tests. Altogether, there were 978 samples collected and tested.The positive rate for salmonella was 6.44%.The salmonella isolates were distributed in 5 groups with 13 serotypes. Among them, 29.69% is antibiotic resistant. The study showed that there were salmonella contamination existing in raw or frozen poultry meat, sea food and eggs in surveillance spots. And it is necessary to further strengthen public hygiene supervision and monitoring in the process of slaughtering, transportation and processing,and implement the standard of proper use of antibiotics in husbandry setting to minimize the occurrence of food born diseases.
