目的了解广西动物性水产品副溶血性弧菌(vibrio parahaemolyticus,VP)的污染现状,为VP食物中毒预防及溯源提供科学依据。方法 2010～2011年从广西8个地级市的餐饮企业、集贸市场和卖场超市等采集不同类别动物性水产品共389份,按照GB/T4789.7-2003《食品卫生微生物学检验方法副溶血性弧菌检验》进行检验。结果 (1)水产品VP总检出率21.59%,海产品VP检出率(31.43%)明显高于淡水产品(13.55%)(χ2=18.173,P﹤0.001);(2)在选定的8个城市中,北海市的VP检出率(26.67%)明显高于柳州(6.25%)、桂林(10.42%)和百色市(6.67%)(χ2值分别为7.157、4.106和6.48,P值分别为0.007、0.043和0.011);(3)在不同采样场所中,餐饮企业(26.47%)和卖场超市(38.78%)的VP检出率均明显高于集贸市场(14.22%)(χ2分别为7.925和15.503,P值分别为0.005和﹤0.05);(4)夏季VP检出率最高为27.88%(χ2=20.187,P﹤0.001)。结论广西动物性水产品VP污染持续存在,且存在水产品类别、地域、场所和季节的差别,应采取相应措施对高发地区、高发场所和高发季节水产品进行重点监测和管理。
Objective To understand the pollution status of vibrio parahaemolyticus (VP) in animal aquatic products in Guangxi and provide a scientific basis for the prevention and traceability of VP food poisoning. Methods A total of 389 samples of different types of animal aquatic products were collected from catering enterprises, bazaars and supermarkets in 8 prefecture-level cities of Guangxi from 2010 to 2011. According to GB / T4789.7-2003, “Method of Microbiological Examination of Food Hygiene Vibrio hemolyticus test ”for testing. Results (1) The total detection rate of VP in aquatic products was 21.59% and the detection rate of marine products VP was 31.43% (13.55%) (χ2 = 18.173, P <0.001). (2) Among eight cities, the detection rate of VP in Beihai was significantly higher than that in Liuzhou (6.25%), Guilin (10.42%) and Baise (6.67%) (χ2 = 7.157, 4.106 and 6.48, P = 0.007, 0.043 and 0.011 respectively); (3) The detection rate of VP in catering establishments (26.47%) and supermarkets (38.78%) were significantly higher than that in bazaars (χ2 P values were 0.005 and <0.05, respectively). (4) The highest detection rate of summer VP was 27.88% (χ2 = 20.187, P <0.001). Conclusion The VP pollution of animal aquatic products in Guangxi persists. There are differences in aquatic product categories, regions, places and seasons. Measures should be taken to monitor and manage the high incidence areas, high incidence areas and high season aquatic products.
