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)食物中毒事件调查分析

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。

Investigation and analysis for an event of Burkholderiagladioli (Pseudomonas cocovenenans subtype Farino fermentans) food poison in Yunnan province

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).
