中文摘要:

      目的 调查分析云南省一例唐菖蒲伯克霍尔德氏菌(椰毒假单胞菌酵米面亚种)食物中毒事件。 方法 参照GB/T 4789.29-2003《食品卫生微生物学检验 椰毒假单胞菌酵米面亚种检验》对样品进行唐菖蒲伯克霍尔德氏菌检测。按照GB 5009.189-2016《食品安全国家标准 食品中米酵菌酸的测定》检测样品中的米酵菌酸, 采用液相色谱法对样品进行检测。用VITEK 2COMPACT 全自动微生物生化鉴定仪和飞行时间质谱进行微生物鉴定。结果 2份样品鉴定结果为唐菖蒲伯克霍尔德菌。2份样品均检测出米酵菌酸, 含量分别为18.0和24.2 mg/kg。 结论 本次食物中毒源于食源性唐菖蒲伯克霍尔德氏菌(椰毒假单胞菌酵米面亚种)污染。

英文摘要:

      Objective To investigate and analyze an event of Burkholderia gladioli (Pseudomonas cocovenenans subtype Farino fermentans) in Yunnan province. Methods Burkholderiagladioli in samples were detected according to GB/T 4789.29-2003 Food hygiene-Microbiological test-Pseudomonas cocovenenans. Farino fermentan. The bongkrekic acid in samples was detected according to GB 5009.189-2016 National food safety standard-Determination of bongkrekic axid in Food. The microbiological identification was conducted by VITEK 2COMPACT automatic microbial biochemical analyzer and time-of-flight mass spectrometry. Results The results of 2 samples were identified as Burkholderiagladioli. The bongkrekic acid was detected in 2 samples, and the content were 18.0 and 24.2 mg/kg, respectively. Conclusion This food poisoning accident is originated from the contamination of by Burkholderia gladioli (Pseudomonas cocovenenans. Subtype. Farino fermentans).
