ISO 38564 Herbicide Testing in Plant-Based Foods
The ISO 38564 standard provides a comprehensive protocol for detecting and quantifying herbicides in plant-based foods. This service is essential for ensuring that food products meet strict regulatory requirements, protect consumer health, and maintain the integrity of agricultural practices.
Herbicide residues can accumulate in various plant-based foods due to improper application or overuse by farmers. Prolonged exposure to these residues can lead to adverse health effects, particularly when consumed by infants, children, and individuals with compromised immune systems. Therefore, rigorous testing is crucial for maintaining public safety.
ISO 38564 outlines a series of steps aimed at identifying herbicide residues in plant-based foods through both qualitative and quantitative methods. The process involves several key stages: sample collection, preliminary screening, confirmation analysis, quantification, and reporting. Each step ensures accurate and reliable results that are compliant with international standards.
Sample preparation is critical to the success of any analytical procedure. For ISO 38564-compliant testing, samples must be processed carefully according to specified guidelines. This includes washing, cutting, and homogenizing the sample. Proper handling prevents contamination and ensures accurate results. Once prepared, the sample undergoes extraction using solvent-based techniques or solid-phase extraction methods.
The extracted herbicide residues are then analyzed via instrumental methods such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS). These advanced analytical tools offer high sensitivity and selectivity, making them ideal for detecting even trace levels of herbicides.
After analysis, the results are compared against established limits set forth by relevant regulatory bodies. Compliance with these limits ensures that food products do not pose risks to human health or safety. Any detected residues exceeding allowable thresholds require further investigation into their source and potential impact on consumers.
The final report provides detailed information about the tested sample, including specific herbicides identified, concentrations measured, and whether they fall within acceptable ranges according to applicable regulations.
| Herbicide | Detection Limit (µg/kg) | Acceptable Concentration Range (µg/kg) |
|---|---|---|
| Atrazine | 0.1 | ≤ 0.5 |
| Diazinon | 0.02 | ≤ 0.3 |
| Ethylene dibromide (EDB) | 0.01 | ≤ 0.1 |
| Metribuzin | 0.5 | ≤ 2 |
The above table illustrates some common herbicides and their respective detection limits and acceptable concentration ranges according to ISO 38564.
By adhering strictly to this standard, laboratories ensure they are providing accurate, reliable data that can be used by various stakeholders including quality managers, compliance officers, R&D engineers, and procurement teams. This information helps these professionals make informed decisions regarding product safety and regulatory adherence.
