    摘要:

    目的 了解上海市各餐饮企业生食肉制品微生物污染状况,为该类样品食品安全监督提供科学依据。方法 采用国家标准规定的检测方法,2019年从上海市餐饮企业抽取共计198份生食肉制品及其相关产品进行了卫生指示菌和常见食源性致病菌检测,并用SPSS 16.0软件对测定结果进行分析。结果 从卫生指示菌看,不同样品中,生食肉制品成品及其原辅料菌落总数≥100 000 CFU/g占比2.06%(2/97),大肠菌群超过100 CFU/g占比5.15%(5/97),大肠埃希菌检出率为2.06%(2/97),其中牛肉原料样品检出率为11.11%(2/18),定量均为10 CFU/g;加工过程环节检测中,大肠菌群检出率为12.87%(13/101),其中加工器具大肠菌群检出率为20.83%(10/48)高于餐饮具样品的5.66%(3/53),差异有统计学意义(χ2=12.678,P<0.05)。从食源性致病菌检测情况看,牛肉原料及成品沙门菌检出率均为5.56%(1/18),其余样品均未检出食源性致病菌。结论 2019年上海市餐饮生食肉制品成品、原料卫生指示菌和沙门菌的检出值得关注,应重视与食品直接接触的加工器具的卫生监督。

    Abstract:

    Objective To detect microbial contamination status of edible raw meat products in catering enterprises of Shanghai and to provide reference for food safety and supervision. Methods According to the national standards a total of 198 batches of edible raw meat products and related products from catering enterprises in Shanghai in 2019 were tested for hygienic indicator organisms and common foodborne pathogenic bacteria. SPSS 16.0 software was used to analyze the test result. Results Judging from the hygienic indicator organisms, 2.06% (2/97) of edible raw meat products, raw and supplementary materials had aerobic plate count ≥ 100 000 CFU/g, 5.15% (5/97) of them had coliforms more than 100 CFU/g, and the detection rate of Escherichia coli was 2.06%(2/97), among which the detection rate of raw beef samples was 11.11% (2/18) and the quantitative value was all 10 CFU/g. In terms of the contact surface samples of ready-to-eat foods, the detection rate of coliform was 12.87%(13/101), among which the positive rate of processing tools and utensils was 20.83% (10/48), higher than the tableware samples 5.66%(3/53) (χ2=12.678,P<0.05). According to the detection of foodborne pathogenic bacteria, the detection rates of Salmonella in raw beef and finished products were 5.56% (1/18) respectively and no foodborne pathogens were detected in the remaining samples. Conclusion According to the result of this survey, the detection of the hygienic indicator organisms and Salmonella of edible raw meat products and the raw materials from catering in Shanghai in 2019 was worthy of attention, and the supervison agency should attach importance to the hygienic supervision of the processing tools and utensils in direct contact with ready-to-eat foods.
