Microbiology
The following standardized methods are employed for microbiology testing:
USP <2021> – Microbial Enumeration Tests for Nutritional and Dietary Supplements
- Total aerobic microbial count
- Total combined molds and yeasts count
- Enterobacterial (bile-tolerant gram-negative bacteria) count
USP <2022> – Microbiological Procedures for Absence of Specific Microorganisms for Nutritional and Dietary Supplements
- Staphylococcus aureus
- Salmonella species
- Escherichia coli (E. coli)
- Clostridium species
USP <2023> – Microbiological Attributes of Nonsterile Nutritional and Dietary Supplements
- Microbial contamination
With the addition of a real-time PCR instrument and expanded microbiological lab space, our list of microbiological testing capabilities been expanded to include:
