      Objective To investigate the contamination situations of Pseudomonas aeruginosa in packaged drinking water in Xuzhou. Methods According to GB 8538-2016 National standard for food safety-Methods for examination of drinking natural mineral water, Pseudomonas aeruginosa in packaged drinking water sampled in Xuzhou city in 2018 was determined. Results A total of 310 batches of packaged drinking water sampled were determined in 2018 and 48 water samples were detected for P. aeruginosa, with the detection rate of 15.5%. The detection rate of P. aeruginosa in production was higher than that in circulation, and the detection rate of P. aeruginosa in barreled drinking water was significantly higher than that in bottled drinking water. Conclusion There are potential risks of P. aeruginosa contamination in packaged drinking water in Xuzhou city, and relevant departments should strengthen supervision and management.
