ICH guideline Q4B Annex 4A on evaluation and suggestion of pharmacopoeial texts for use from the ICH areas on micro enumeration - Phase five
You should I want to know, if it is eligible for microbial limit of a sample to exceed its conditions e.g if TAMC is 1000cfu/gm is often 3000cfu/gm?
A test exhibiting “absence of advancement” all through security storage wouldn't automatically rule out growth possible. Expansion opportunity could be superior decided using the AET where organisms are actually included to the item, or by h2o activity (Aw) measurements in non-aqueous formulation, or a mix of equally tests.
