ISO 33375 Aflatoxin M1 Detection in Baby Foods
The detection of aflatoxin M1 (AFM1) in infant formula and baby food is a critical aspect of ensuring the safety and quality of these products. AFM1, which results from the metabolism of aflatoxin B1 by gut bacteria, poses significant health risks to infants and young children due to their developing immune systems and lower detoxification capabilities. Compliance with international standards like ISO 33375 is essential for manufacturers aiming to meet regulatory requirements and protect public health.
The process involves several key steps: sample collection, preparation, extraction, purification, and analysis. The sample must be representative of the batch or lot being tested. Proper handling and storage are crucial to maintain sample integrity before and during testing. Extraction techniques such as liquid-liquid partitioning or solid-phase extraction (SPE) can be used depending on the matrix complexity.
The use of advanced analytical instrumentation is vital for accurate detection. High-performance liquid chromatography (HPLC), coupled with fluorescence detection, is a common method. This approach allows for precise quantification and qualitative identification of AFM1 in various baby food products. The system must be capable of handling low concentrations due to the stringent regulatory limits.
Standard operating procedures (SOPs) are essential for consistent results. They outline all steps from sample preparation through final analysis, including calibration of instruments, maintenance schedules, and quality control checks. Regular validation ensures that analytical methods remain robust over time.

The standard specifies detailed procedures for sample preparation, extraction, cleanup, and analysis. It also provides criteria for method validation covering linearity, precision, accuracy, limit of quantitation (LOQ), and robustness. Compliance with these standards is crucial not only for regulatory compliance but also to build consumer trust.
Understanding the potential sources of contamination helps in implementing effective mitigation strategies. Mold growth during processing or storage can lead to AFM1 formation, emphasizing the need for strict hygiene practices throughout the supply chain. Monitoring environmental conditions like temperature and humidity plays a role too.
Why It Matters
The importance of detecting aflatoxin M1 in baby foods cannot be overstated. Exposure to even trace amounts can have severe adverse effects on infants, including liver damage, stunted growth, and increased susceptibility to infections. Long-term exposure may lead to more serious conditions like cancer.
- Regulatory compliance: Adherence ensures products meet strict safety thresholds set by regulatory bodies worldwide.
- Consumer trust: Demonstrating a commitment to product safety fosters confidence among parents who are already dealing with the challenges of raising infants.
- Risk management: Early detection allows for prompt corrective actions, minimizing potential health hazards and financial losses.
The significance extends beyond legal requirements; it reflects a broader responsibility towards public health. By preventing even small amounts of contamination, laboratories contribute to safeguarding vulnerable populations.

The standard provides comprehensive guidelines for the entire analytical process, from sample preparation to final reporting. It ensures that laboratories maintain consistent results across different batches and facilities. This consistency is critical given the stringent regulatory limits for AFM1 in baby foods.
Method validation based on ISO 33375 includes multiple parameters such as linearity over a wide range, inter-laboratory reproducibility, robustness against matrix effects, and recovery rates. These validations are essential to ensure that the analytical method is reliable and capable of detecting AFM1 accurately.
Quality and Reliability Assurance
- Use of certified reference materials (CRMs) for calibration and quality control checks.
- Regular method validation and performance verification to maintain accuracy and precision.
The implementation of robust quality assurance protocols ensures that every test result is reliable and can be trusted. Certified CRMs provide a benchmark against which analytical results are compared, ensuring consistency within batches as well as between different laboratories.
Performance verification involves periodic re-assessment using known samples or those generated under controlled conditions to confirm the ongoing reliability of the testing process. This continuous monitoring helps identify any potential drifts in performance early enough for corrective action.
