For a supplied product or service, When the antimicrobial action with respect to your microorganism for which testing is prescribed can not be neutralized, then it is to get assumed that the inhibited microorganism will not be current in the product or service.
Additionally, this method is perhaps flawed in that the inoculum doesn't have a COA and also a gradual drop in viability may not be easily detected. Testing with a reference substance gives an independent and specific exterior calibration issue.
