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:
