Why Perform A Product D-Value Study?

The most direct method for evaluating the resistance of the test organism (a bioburden isolate or G. stearothermophilus spores) is by performing a D-value study. When evaluating the bioburden, it is not necessary to test every organism isolated, only the most resistant (which can be isolated though the use of a heat shock screening procedure).
