Uncertainty Evaluation and Analysis of Enterobacteriaceae Count in Proficiency Testing
: Objective: To analyze and evaluate the uncertainty the results of the proficiency testing (ACAS-PT 1083 (2021)) of enterobacteriaceae count. Methods: According to the operational instructions of capability verification and GB 4789.41-2016 National food safety standard-Food microbiology test-Enterobacteriaceae count, the enterobacteriaceae of the capability verification sample were tested quantitatively. The suspected colonies were identified by VITEK2. The uncertainty of test results was assessed in accordance with JJF 1059.1-2012 and GB/T 27418-2017 Evaluation and expression of measurement uncertainty. Results: The test result of sample 21-Q997 was 4.2 ×10 3 CFU/mL. The test results were satisfactory as the Z values of the proficiency test was -0.8 (|Z|
