Proficiency Testing of Pseudomonas aeruginosa Qualitative in Mineral Water and Results Analysisi
Through participating the proficiency testing of Pseudomonas aeruginosa qualitative in mineral water,expanded the test method and extended the test idea to improve the accuracy of Pseudomonas aeruginosa testing.Samples were diluted according to the proficiency testing guidance and National Food Safety Standard-Test method for dringking natural mineral water(GB 8538-2022),two samples(23-E4799 and 23-D8535)were tested for Pseudomonas aeruginosa by routine biochemical identification,VITEK2 automatic microbial identification system and specific gene sequencing.Pseudomonas aeruginosa was detected in sample 23-D8535,while no 23-D8535 was detected in sample 23-E4799.The results of the three methods were consistent,and the results were satisfactory,which proved that the laboratory had the ability to detect Pseudomonas aeruginosa in mineral water.
