Qalitex Laboratories, an ISO 17025-accredited third-party testing laboratory, has released a comprehensive guide on mycotoxin contamination in botanical dietary supplements. The analysis covers the toxicology of aflatoxins, ochratoxin A, and fumonisins, identifies high-risk botanical ingredients, and outlines ISO 17025-accredited testing protocols to help brands avoid contamination-related recalls and regulatory enforcement actions.

Why it matters

Mycotoxin contamination in botanical ingredients is a serious and often underappreciated risk for dietary supplement brands. Implementing rigorous testing protocols can help brands assure product safety and avoid potential compliance issues, while those relying solely on supplier assurances face significant risks.

The details

The guide explains that mycotoxins are toxic compounds produced by mold species that cannot be eliminated by heat or standard processing. Contaminated ingredients retain mycotoxins through drying, grinding, and extraction. The analysis covers the toxicology of aflatoxin B1, ochratoxin A, and fumonisins, and identifies botanical ingredients like turmeric, black pepper, dried ginger, ashwagandha, milk thistle, and corn-based products as being particularly susceptible to mycotoxin contamination, especially when sourced from tropical or subtropical regions. The guide recommends LC-MS/MS as the preferred method for sensitive, specific, and multi-analyte mycotoxin testing, and advises brands to test every incoming lot of high-risk botanical ingredients.

  • The guide was released on March 30, 2026.

What they’re saying

“Mycotoxin contamination in botanical ingredients is a serious and often underappreciated risk. Aflatoxin B1, for example, is a potent carcinogen that can exceed FDA action levels even when no visual mold is present. Brands that implement rigorous mycotoxin testing can confidently assure their customers of product safety, while those relying solely on supplier assurances face potential compliance risks.”

— Nour Abochama, Vice President of Operations

The takeaway

This guide highlights the critical importance for dietary supplement brands to implement comprehensive mycotoxin testing protocols, especially for high-risk botanical ingredients, in order to ensure product safety, avoid costly recalls, and maintain regulatory compliance.
