The requirements range dependant upon the criticality from the production area to merchandise sterility. Depending upon the cleanroom classification, there can be quite stringent necessities on the result of environmental monitoring.
The not too long ago harmonized Microbial Limits Tests get more info (USP 2003b, USP 2003c) grow the necessities to an evaluation on the differential and selective Attributes in the media, Along with confirming the nutritive Homes.
