6. Chapter 2: Microbial Examination of Non-Sterile Products
This section contains supplemental information for the quantitative
enumeration of viable microorganisms and the determination of the absence of
specified microorganisms in finished pharmaceutical products and raw
materials, previously referred to as Microbial Limits Testing (MLT). The
detailed procedures for these tests are not addressed in this PMM chapter
because they are found in USP <60> MICROBIOLOGICAL EXAMINATION OF
NONSTERILE PRODUCTS: TESTS FOR BURKHOLDERIA CEPACIA
COMPLEX, USP <61> MICROBIOLOGICAL EXAMINATION OF
NONSTERILE PRODUCTS: MICROBIAL ENUMERATION TESTS and <62>
MICROBIOLOGICAL EXAMINATION OF NONSTERILE PRODUCTS: TESTS
FOR SPECIFIED MICROORGANISMS.
USP Chapter <60> is a test to detect the presence of Burkholderia cepacia
species in a substance or preparation. Products for inhalation use or aqueous
preparations for oral, oromucosal, cutaneous, or nasal USP <61> describes the
methods for enumeration of microorganisms from pharmaceuticals and
includes membrane filtration, conventional plate count (including pour-plate
method, surface- spread method), and the Most-Probable-Number (MPN).
USP Chapter <62> describes specific enrichment procedures depending on
Category 1 Products
Bacteria:
Not less than 1.0 log reduction from the initial calculated
count at 7 days, not less than 3.0 log reduction from the
initial count at 14 days, and no increase from the 14-day
count at 28 days.
Yeast and Molds:
No increase from the initial calculated count at 7, 14, and
28 days.
