| [目的]本研究旨在解决包装饮用水中铜绿假单胞菌污染特性。[方法]对2022-2024年度湖南省监督抽检中,省内市售、本省企业生产的包装饮用水检出铜绿假单胞菌的情况进行分析。[结果]三年铜绿假单胞菌检出率为8.15%,2024年因监管强化显著下降至5.74%；其他饮用水(9.44%)与压盖包装(8.65%)风险最高；夏秋季(三季度11.34%)及常德、湘西等地区(>15%)为污染高发区。[结论]重点加强水源细菌保护膜防控、季节性工艺优化及高风险区域监管,可以有效减少铜绿假单胞菌的污染,从而提高包装饮用水产品的抽检合格率。研究结果为湖南省包装饮用水质量提升提供了关键数据支持,揭示的“气候-工艺-管理”多重风险叠加机制,对南方湿热地区食品微生物防控具有参考价值。 |

| [Objective] this study aimed to solve the pollution characteristics of Pseudomonas aeruginosa in packaged drinking water. [method] the detection of Pseudomonas aeruginosa in packaged drinking water sold in the province and produced by enterprises in Hunan Province during the supervision and sampling inspection in 2022-2024 was analyzed. [results] the detection rate of Pseudomonas aeruginosa was 8.15% in three years, and significantly decreased to 5.74% in 2024 due to the strengthening of supervision; Other drinking water (9.44%) and gland packing (8.65%) had the highest risk; Summer and autumn (11.34% in the third quarter) and Changde, Xiangxi and other regions (>15%) are the high-risk areas of pollution. [Conclusion] strengthening the prevention and control of water source bacterial protective film, seasonal process optimization and high-risk regional supervision can effectively reduce the pollution of Pseudomonas aeruginosa, thereby improving the sampling inspection qualification rate of packaged drinking water products. The research results provide key data support for the improvement of the quality of packaged drinking water in Hunan Province, and reveal the "climate process management" multiple risk superposition mechanism, which has reference value for the prevention and control of food microorganisms in hot and humid areas in South China. |
