目的对广州市白云区2005-2008年发生的细菌性食物中毒的病原学检验结果进行分析,了解其发生的特点,为制定预防及控制食物中毒措施提供科学依据。方法按照国家标准方法对白云区2005-2008年发生的39起细菌性食物中毒的病原菌进行微生物学检验,并对检测数据进行统计分析。结果2005-2008年白云区共发生细菌性食物中毒39起,其中6-10月共发生37起,占总起数的94.87%;39起细菌性食物中毒共采集样本915份,检出病原菌328份,总检出率为35.85%,其中副溶血性弧菌检出率为17.60%,奇异变形杆菌检出率为9.62%,沙门菌检出率为6.34%,金黄色葡萄球菌检出率为2.30%。检出病原菌的样本主要为病人肛拭子(呕吐物),检出率为60.87%(252/414);食物中毒发生的场所主要是集体食堂,共22起,占总起数的56.4%。结论应加强对集体食堂的食品卫生监督和对从业人员的健康教育,有效预防细菌性食物中毒的发生。
Objective To analyze the etiological test results of bacterial food poisoning occurred in Baiyun District of Guangzhou from 2005 to 2008, understand its characteristics and provide a scientific basis for the prevention and control of food poisoning. Methods According to the national standard method, 39 bacterial pathogenic bacteria of bacterial food poisoning occurred in Baiyun District from 2005 to 2008 were tested by microbiology, and the detection data were analyzed statistically. Results A total of 39 bacterial food poisoning occurred in Baiyun District from 2005 to 2008, of which 37 occurred from June to October, accounting for 94.87% of the total. Nineteen bacterial food poisoning samples were collected from 915 samples. Pathogenic bacteria 328 , The total detection rate was 35.85%. The detection rate of Vibrio parahaemolyticus was 17.60%, the detection rate of Proteus mirabilis was 9.62%, the detection rate of Salmonella was 6.34%, the detection rate of Staphylococcus aureus 2.30%. The samples of pathogenic bacteria were mainly anal swabs (vomitus), with a detection rate of 60.87% (252/414). Food poisoning occurred mainly in collective canteens, with a total of 22, accounting for 56.4% of the total number of cases. Conclusion The food hygiene supervision of collective canteens and the health education of practitioners should be strengthened to effectively prevent the occurrence of bacterial food poisoning.
