中文摘要:

      目的 对广东地区2018年市售的包装饮用水及天然矿泉水铜绿假单胞菌污染情况进行分析及检测。方法 采用国标《GB 8538-2016食品安全国家标准饮用天然矿泉水检验方法》对实验室2018年抽检的包装饮用水及天然矿泉水进行铜绿假单胞菌项目检测及分析。结果 275份包装饮用水及天然矿泉水中23份样品检出铜绿假单胞菌, 总阳性率为8.36%; 包装饮用水、天然矿泉水的阳性率分别为9.87%、1.92%; 包装饮用水中桶装水的阳性率为100%, 共检出76株阳性菌株, 菌株形态主要为蓝绿色。结论 包装饮用水中铜绿假单胞菌污染状况比天然矿泉水严重, 且集中在桶装包装饮用水中。建议桶装饮用水生产企业采取控制措施, 相关监督部门应加强监督管理。

英文摘要:

      Objective To analyze and detect the Pseudomonas aeruginosa contamination in packaged drinking water and natural mineral water in Guangdong in 2018. Methods The national standard GB 8538-2016 National standard for food safety testing methods for drinking natural mineral water was used to test and analyze the Pseudomonas aeruginosa in the drinking water and natural mineral water sampled by the laboratory in 2018. Results Pseudomonas aeruginosa was detected in 23 samples of natural mineral water among 275 samples of packaged drinking water, with a total positive rate of 8.36%. The positive rates of packaged drinking water and natural mineral water were 9.87% and 1.92%, respectively. The positive rate of bottled water in packaged drinking water was 100%, and 76 positive strains were detected in total. The shape of the strains was mainly blue-green. Conclusion Pseudomonas aeruginosa contamination in packaged drinking water is more serious than natural mineral water and concentrated in bottled packaged drinking water. The barreled drinking water production enterprises should take control measures and relevant supervision departments should strengthen supervision and management.
