中文摘要:

      目的 检测成都市散装糕点微生物的污染情况, 分析主要污染来源以及风险点并提出改进措施。方法 参考GB 7099-2015《食品安全国家标准 糕点、面包》中的微生物要求对市场上销售散装糕点进行菌落总数、大肠菌群、霉菌以及致病菌(沙门氏菌、金黄色葡萄球菌)检测, 并对含肉制品散装糕点进行单核细胞增生李斯特氏菌检测。对直接接触食品的包装材料进行大肠菌群检测。结果 散装糕点菌落总数不合格率为63%, 大肠菌群不合格率40%, 霉菌不合格率为16%。均未检出致病菌。结论 成都市散装糕点微生物不合格率较高, 散装糕点生产销售企业也存在一定食品安全问题, 监管部门对该行业应加强管理力度。

英文摘要:

      Objective To detect the microbial contamination of bulk pastries in Chengdu, analyze the main sources of pollution and risk points and propose improvement measures. Methods According to the microbial requirements of GB 7099-2015 National food safety standards-Pastries and Bread, total bacterial colonies, coliforms, mold and pathogenic bacteria (Salmonella, Staphylococcus aureus) in bulk pastries on the market were detected. Listeria monocytogenes were detected in bulk cakes containing meat products. The packaging materials in direct contact with food were tested for coliforms. Results The unqualified rate of the total bacteria colonies number of bulk pastry was 63%, the unqualified rate of coliform bacteria was 40%, and the unqualified rate of mold was 16%. No pathogenic bacteria were detected. Conclusion Chengdu's bulk pastry microorganisms have a high rate of unqualified microorganisms, and there are certain food safety issues in the production and sales enterprises of bulk pastries. Regulatory authorities should strengthen management of the industry.
