What is the Purpose of Microbiological Testing?
Microbiological testing is carried out in order:
Identify the absence or existence of certain microorganisms
Enumerate microorganisms both aerobically and anaerobically
Check if the product exceeds regulated microbiological limits
Determine the degree of microbial contamination
Help ensure product safety, stability, and efficacy
Specific microbiological testing helps clients identify contamination issues first, thereby lessening the risk of contamination in products that are not safe and of good quality for the market.
Testing Methods of Microbiology
Microbiology department for microbiological testing has defined and approved methods which are recognized and accepted in the industry, such as:
Important USP Chapters Observed:
<51> Antimicrobial Effectiveness Testing
<61> Microbial Enumeration Tests
<62> Tests for Specified Microorganisms
<85> Bacterial Endotoxins
<60> Burkholderia Cepacia Complex
<2021> <2022> Nutritional Supplements Testing
Common Microbiological Testing Strategies
- Sterility assays
- Tests for microbial content and isolation
- Total viable count (TVC)
- Yeast and mold testing
- Pathogen testing (e.g., E. coli, Salmonella, Staphylococcus aureus)
- Bacterial endotoxins test using LAL
- Vitamin and antibiotic assays
- Preservative efficacy testing (Challenge test)
These Testing methods of microbiology are customized according to product type to assess its safety for use or distribution.
Microbiological Testing for Pharmaceutical Products
At Chromak Research, we specialize in conducting microbiological tests on pharmaceuticals. From raw materials to finished products, our lab ensures that all pharmaceutical products undergo necessary microbiological tests as per regulations.
The limiting steps in a validation study include, but are not limited to, the following:
- Total microbial count;
- Specific pathogens;
- Antimicrobial preservative effectiveness;
- Bacterial endotoxins;
- Sterility (when required).
Each of the microbiological tests is carried out according to the standards of United States Pharmacopeia Chapters <51>, <61>, and <62>, compliance with regulations set.
Benefits from Microbiological Testing
Each microbiological test performed delivers value on its own:
Regulatory compliance with pharmacopeia standards;
Early detection of potential product contamination;
Operational assurance on product safety and shelf life;
Validation of cleanliness and hygiene in the facility;
Confirmation of efficacy of antimicrobial preservatives.
Our services of microbiological testing cover many sectors, namely: nutraceutical, cosmetics, chemistry, food, and pharma, ensuring the regulations of the market, enhancing safety for the consumers.
Method Qualification and Release Testing
Before routinely performing microbiological tests, method qualification serves as the base, allowing the setting of proper neutralizers, dilution factors, and enrichment media to mask anti-microbial effects already used in drug formulations. This process ensures we validate that the methods used for testing can be trusted for the matrix targeted.
We carry out methodology compliance testing as per the guidelines mentioned in:
- Testing of Antimicrobial Effectiveness USP <51>
- Microbial Enumeration Test USP <61>
- Listed Microorganisms USP <62>
Our microbiologists make sure all procedures are correct and complete, along with the method steps, product distribution, and regulatory directives.
