      Objective To master pollution situation of Pseudomonas aeruginosa in packaged drinking water produced and sold in Chengdu since implementation of the GB 19298-2014 National standard for food safety Packaging drinking water. Methods The detection of Pseudomonas aeruginosa in packaged drinking water in Chengdu from 2015 to 2018 was statistically analyzed, according to the type of drinking water in bottles and barrels, the type of drinking water (pure water, mineral water, other drinking water), the production season and the location of the site. Results A total of 994 batches were detected, and the detection rate was 8.8%. The detection rate of bottled drinking water was 0.6%, and the detection rate of barreled drinking water reached 12.9%; Pseudomonas aeruginosa was isolated from various types of barreled water, the detection rate of pure water, mineral water, and other drinking water were 2.0%, 5.4 %, and 15.5%, respectively. According to seasonal statistics, the detection rate in the third quarter was the highest, as high as 22.1%. The location of Pseudomonas aeruginosa packaging drinking water factory was mainly distributed in the northwest of Chengdu (Lushan Mountains). Conclusion It is found that the contamination of Pseudomonas aeruginosa in barreled drinking water is very serious (especially other drinking water in barrel); the pollution situation is the most serious in the third quarter, and the area is mainly concentrated in the area of the Lushan Mountains.
