Abstract:To understand the microbial indicators of frozen rice products in the region and probe the uncertainty assessment methods for testing the results of Staphylococcus aureus.the products were sampled and test accord ing to GB 4789.1-2010，GB 4789.4-2010，GB 4789.10-2010 and GB 19295-2011 and evaluated uncertainty of the samples based on JJF1059.1-2012，poisson scatter and related statistical methods to evaluate uncertainty of the samples.142 quick-frozen product of wheat flour and rice，including 88 samples of Frozen without cook ing and 54 samples of Cooked before frozen，both qualified rate of them was 100%.According to the methods used，it was concluded that the average results of two samples was 290 CFU/g and 20 CFU/g.Also the relative standard uncertainty of test results of was 30 CFU/g and 4 CFU/g respectively.Evaluation method used in this paper could estimate the uncertainty of test results of Staphylococcus aureus coming form quick-frozen products of wheat flour and rice，which was suitable to evaluate the safety of them.
