The not too long ago harmonized Microbial Restrictions Tests (USP 2003b, USP 2003c) broaden the requirements to an evaluation on the differential and selective Houses of the media, As well as confirming the nutritive Homes. At last, the proposed USP chapter on microbiological laboratory practices stresses the necessity to sufficiently control the growth media (USP 2004).
