NSF to Provide Enhanced Validation Testing for Dietary Supplements

NSF/ANSI Standard 173: 2006 Now Includes Soleris Test Method to Verify Dietary Supplements Meet Label Claims

Ann Arbor, MI –NSF International and Neogen are teaming up to put supplements under closer scrutiny to help protect consumers.

Neogen, a company committed to developing products dedicated to food safety, recently acquired a new microbial test system (SolerisTM) to detect contamination. NSF International is a not-for-profit organization committed to providing public health solutions worldwide. Together, NSF and Neogen will offer comprehensive validation tests and testing services that are essential to ensure that products meet label content claims and do not contain contaminants such as unintended microbes, lead and heavy metals.

NSF/ANSI Standard 173 –– the American National Standard for dietary supplements and the standard that provides the foundation for the NSF Dietary Supplement Certification Program –– helps manufacturers ensure that their supplements and their ingredients are not adulterated with contaminants and are labeled accurately. NSF recently published a new edition of NSF/ANSI Standard 173 after completing a study, which verified equivalency between Neogen’s rapid Soleris microbial test protocols and traditional USP plate-counting methods when testing dietary supplements for contamination. The 2006 edition of the standard now allows rapid testing procedures by using the Soleris system in the testing of microbiological contaminants.

"We're very pleased any time independent studies demonstrate the intended performance of our testing products, but even more so with an organization as prestigious as NSF International. They literally set the standard for many types of safety and quality testing," said Ed Bradley, Neogen's vice president of food safety. "Including our rapid testing protocols in the NSF standard will allow more microbial testers to discover the obvious speed and significant labor-reducing benefits of the Soleris system over traditional methods."

NSF/ANSI Standard 173 also includes:

  • limits for contaminants, including substances such as pesticides, microbial count, and heavy metals;
  • criteria for verifying the quantity of active ingredients; and
  • sets criteria for compliance with Good Manufacturing Practices (GMP) and label requirements.

NSF’s microbiology lab will use the Soleris equipment to develop additional validation assays to detect microbial contamination. The system measures microbial growth by monitoring pH and other biochemical reactions that generate a color change as microorganisms grow and metabolize. This process enables operators to easily identify, monitor and detect any problem area.

According to Lori Bestervelt, Ph.D., NSF chief technical officer and senior vice president: “This is key for companies who do not have the resources in-house to conduct comprehensive validation testing of dietary supplements for yeast and mold, total aerobic count and Enterobacteriaceae. The Soleris test system will also play an important role in quickly detecting foodborne bacteria.”
