WHY USE NEUTRALISERS IN YOUR ENVIRONMENTAL MONITORING PLATES?

WHY USE NEUTRALISERS IN YOUR ENVIRONMENTAL MONITORING PLATES?
02/09/2020

For those of you working to the orange guide and/or the guidance in the European Pharmacopoeia, you will notice the absence of specific guidance on how to monitor your cleanrooms. The USP however, does give specific advice on what media to use and specifies that surface sampling must be supplemented with additives to neutralise the effects of disinfectants. To be more precise, the residue left by disinfectants post cleaning affects the efficacy of the growth medium, possibly masking the presence of viable micro-organisms, especially those on surfaces.
