a MPN = Most Probable Number is based on the POD of reference method test portions across labs using the AOAC MPN calculator, with 95% confidence interval b N = Number of test potions c x = Number of positive test portions d POD CP = Candidate method presumptive positive outcomes divided by the total number of trials e POD CC = Candidate method confirmed positive outcomes divided by the total number of trials f dPOD CP = Difference between the candidate method presumptive result and candidate method confirmed result POD values g 95% CI = If the confidence interval of a dPOD does not contain zero, then the difference is statistically significant at the 5% level
