AOAC 2007.11 Multi-Residue Analysis in Dairy
The AOAC International method 2007.11 is a widely recognized and robust technique for the multi-residue analysis of pesticides in dairy products, including milk and its by-products like cheese and butter. This method has been validated to detect over 350 different pesticide residues and their metabolites, making it an essential tool for ensuring food safety compliance.
Dairy products are a prime target for pesticide residue testing because they can be ingested directly or used as ingredients in the production of other foods. Pesticides, particularly organophosphates, carbamates, pyrethroids, and fungicides, can contaminate milk if livestock graze on treated pastures or consume feed containing residues.
The AOAC 2007.11 method is versatile and adaptable to various dairy matrices, including raw milk, pasteurized milk, fermented products like yogurt, and processed dairy items such as butter and cheese. The technique employs gas chromatography with mass spectrometry (GC-MS) for the identification and quantification of pesticide residues.
Sample preparation is critical in this analysis. Raw milk samples are typically filtered to remove particulate matter before extraction using a liquid-liquid partitioning method or solid-phase extraction (SPE). The extracted compounds are then concentrated, cleaned up, and injected into the GC-MS for analysis. For processed dairy products, sample homogenization and appropriate dilution steps ensure accurate residue quantification.
The AOAC 2007.11 method adheres to strict international standards, including ISO/IEC 17025, which governs the competence of testing laboratories. The method’s robustness lies in its ability to achieve high sensitivity and specificity, ensuring that even trace levels of pesticides are detected.
The results from this analysis provide critical insights into the food safety profile of dairy products. Regulatory bodies like the Food and Drug Administration (FDA) and European Food Safety Authority (EFSA) recommend or mandate such testing as part of their compliance programs. Compliance with these standards is essential for maintaining market access in domestic and international markets.
For quality managers, AOAC 2007.11 ensures that dairy products meet the stringent safety standards required by consumers. Compliance officers rely on this method to validate that imported or domestically produced dairy meets legal thresholds set by regulatory authorities. R&D engineers use it to identify potential contamination sources and develop strategies for mitigating risks. Procurement teams benefit from this testing as they can source ingredients with guaranteed compliance.
By leveraging the AOAC 2007.11 method, laboratories and industries demonstrate their commitment to food safety and regulatory compliance. This approach not only protects consumers but also enhances brand reputation and market competitiveness.
