Objective To analyze and detect the Pseudomonas aeruginosa contamination in packaged drinking water and natural mineral water in Guangdong in 2018. Methods The national standard GB 8538-2016 National standard for food safety testing methods for drinking natural mineral water was used to test and analyze the Pseudomonas aeruginosa in the drinking water and natural mineral water sampled by the laboratory in 2018. Results Pseudomonas aeruginosa was detected in 23 samples of natural mineral water among 275 samples of packaged drinking water, with a total positive rate of 8.36%. The positive rates of packaged drinking water and natural mineral water were 9.87% and 1.92%, respectively. The positive rate of bottled water in packaged drinking water was 100%, and 76 positive strains were detected in total. The shape of the strains was mainly blue-green. Conclusion Pseudomonas aeruginosa contamination in packaged drinking water is more serious than natural mineral water and concentrated in bottled packaged drinking water. The barreled drinking water production enterprises should take control measures and relevant supervision departments should strengthen supervision and management.
