At the same time, the poisonous metabolites of microorganisms and a few pathogenic microorganisms might also result in adverse reactions or secondary bacterial infections to clients. As a result, microbial limit testing for non-sterile drug products is amongst the crucial steps to make certain the standard, protection and effectiveness of medication.

The swab is then rinsed in sterile check here saline or other appropriate menstruum plus the contents plated on nutrient agar plates to acquire an estimate of the practical microbial load on that surface.
