n = number of units comprising the sample; c = number of sample units giving values over m or between m and M.
Would this mean that we need 5x25g tests for Listeria, or make a composite of 5 subsamples and test for 25g. My interpretation is the latter? The note below the chart says "number of units comprising the sample".
Thanks!
