Test material spiked at very low concentrations with agent organisms (such as the aerobic bacterium Staphylococcus aureus, spore forming bacterium Bacillus subtilis, anaerobic bacterium Clostridium sporogenes or the fungus Candida albicans) are utilized to be sure there is no inhibitory result within the sample which can mask contaminants, to be able to validate the test.
With regard to Corrective and Preventive Action, it is important to avoid the quick correct (i.e, correcting the rapid situation and never going over and above the particular problem to evaluate the processes and techniques) which may be the ultimate explanation for failure.
