摘要
为了解北京地区规模化鸡场鸡饮用水的细菌污染情况,对北京地区28个鸡场的基本情况进行了现场调研,并采集水样于实验室进行细菌污染情况检测。检验方法和判定标准均按GB/T 5749-2006《生活饮用水卫生标准》进行。调查结果显示,60.71%(17/28)的采样鸡场鸡饮用水消毒不规律,85.71%(24/28)的鸡场近期没有做过鸡饮用水的检测。水样细菌总数的合格率较低,仅为10.71%(3/28),且水线中从前往后(前段、中段、后段)细菌总数逐渐增多。水样总大肠菌群合格率为50%(14/28),耐热大肠菌群和大肠埃希氏菌的合格率为82.14%(23/28)。
To analyze the quality of chicken＇s drinking water in intensive chicken farms of Beijing, 28 farms in Beijing were investigated, and water samples collected from those farms were taken back to the la-boratory for bacteriological contamination detection. TesIs were conducted under the directions of ＂Stand-ard Test Method for Drinking Water＂ GB/T 5750-2006, and the results were evaluated according to ＂Drinking Water Health Standards＂ GB5749-2006. The results showed that in the 28 farms investigated, 17 （60. 71%） of which did not have regular sterilization and 24 farms （85.710%） did not have bacterial tests recently. There were only 3 chicken farms （10. 71%） which met the standard. As water flows through the waterline, the amount of bacteria becomes larger and larger. The qualification rate of E. coil bacteria in water samples was 500%, while the qualification rates of thermotolerant coliforms and Escherichia coli were both 82.14%.
