Methods and method evaluation for mycotoxins

Area of Science:

• Food safety and toxicology
• Analytical chemistry

Background:

• Mycotoxins are toxic mold metabolites commonly contaminating agricultural products, food, and animal feed.
• Exposure to mycotoxins poses risks of acute, sub-acute, and chronic toxicity to humans and animals.
• Controlling exposure necessitates reliable methods for detecting and quantifying these harmful substances.

Purpose of the Study:

• To outline available methodologies for mycotoxin detection and quantitation.
• To describe the procedures for validating these analytical methods.
• To emphasize the importance of validated methods in managing mycotoxin exposure risks.

Main Methods:

• Review of existing analytical methodologies for mycotoxin analysis.
• Description of validation procedures, including interlaboratory collaborative studies.
• Application of the HORRAT (Horwitz Ratio) for method evaluation.

Main Results:

• The paper details various analytical techniques applicable to mycotoxin detection.
• Validation processes are explained, highlighting the role of collaborative testing.
• The HORRAT is presented as a key metric for assessing method performance.

Conclusions:

• Validated analytical methods are essential for effective control of human and animal exposure to mycotoxins.
• Interlaboratory studies and metrics like HORRAT are vital for ensuring method reliability.
• Continued development and validation of analytical methods are necessary for global food safety.
