Objective To evaluate the uncertainty of mould and yeast count test results in proficiency test samples. Methods According to the operational instructions of capability verification and GB 4789.15-2016 National food safety standard-Food microbiology test-Mold and yeast count, the first method mold and yeast plate count method, the mold and yeast of the capability verification sample were tested quantitatively. The uncertainty of test results was assessed in accordance with JJF 1059.1-2012 Evaluation and expression of measurement uncertainty. Results The extended uncertainty of mould and yeast test results was 0.0238 at 95% confidence interval. Conclusion The evaluation method established in this study can evaluate the uncertainty of the quantitative detection of mould and yeast samples with ability verification, and is suitable for the evaluation of the relevant uncertainty in laboratories with similar testing conditions.
