摘要
目的 了解2022年广西区内包装饮用桶装水中溴酸盐、大肠菌群、铜绿假单胞菌、亚硝酸盐(以NO2-计)的污染情况.方法 根据桶装水类型及检测项目按标准GB 8538-2016《食品安全国家标准饮用天然矿泉水检验方法》、GB 4789.3-2016《食品安全国家标准食品微生物学检验大肠菌群计数》、GB 5009.33-2016《食品安全国家标准食品中亚硝酸盐与硝酸盐的测定》、GB 19298-2014《食品安全国家标准包装饮用水》、GB 2762-2017《食品安全国家标准食品中污染物限量》进行检测判定.结果 收集的204批次桶装包装饮用水中,有55批次铜绿假单胞菌检出,检出率约为26.96％.溴酸盐、大肠菌群、亚硝酸盐均无超标.结论 大多数产品不存在安全问题,但铜绿假单胞菌的污染情况仍然突出,企业应加强对管道、桶的清洗消毒及运输存贮的规范,以确保产品安全.
Abstract
Objective To understand the pollution levels of bromate,coliforms,pseudomonas aeruginosa,nitrite(calculated as NO2-)]of packaged drinking barreled water in Guangxi in 2022.Methods According to the type of water and test items,all pollutions were tested and judged by GB 8538-2016"National standard for food safety Test method for drinking natural mineral water",GB 4789.3-2016"Food safety national standard food Microbiology test Coliform count",GB 5009.33-2016"National standard for food safety Determination of nitrite and nitrate,"GB 19298-2014"Food safety national standard Packaging drinking water",GB 2762-2017"Food safety national standard food Pollutant limits".Results 204 batches of packaged drinking barreled water were collected.Pseudomonas aeruginosa was deteted in 55 batches with a detection rate of 26.96％.Not a single batch exceeded permitted level of bromate,coliform or nitrite.Conclusion Most products are safe,but the pollution of Pseudomonas aeruginosa is still an outstanding problem.Enterprises should strengthen the cleaning and disinfection of pipes and barrels and standardize transportation storage to ensure product safety.
