ISO 57965 Tetracycline Detection in Spices
The ISO 57965 standard provides a robust methodology for detecting tetracycline residues in spices. This service is critical for ensuring that food products and feedstuffs meet regulatory standards, thereby protecting consumer health and maintaining market integrity.
Tetracyclines are a class of broad-spectrum antibiotics widely used to treat bacterial infections in humans and animals. Their presence in food and feed can pose significant risks to public health if consumed by pregnant women, children, or individuals with compromised immune systems. Therefore, regulatory bodies worldwide have established limits for tetracycline residues in spices to ensure compliance.
The ISO 57965 standard specifies a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method that enables the precise and sensitive detection of tetracycline residues at trace levels. The procedure involves several key steps, including sample preparation, derivatization, and instrumental analysis.
Sample preparation is crucial for ensuring accurate results. Typically, this process involves extracting tetracycline from the spice matrix using a suitable solvent followed by purification to remove interfering compounds. Derivatization may be required to enhance the signal-to-noise ratio in the final LC-MS/MS analysis. This step is particularly important when dealing with complex matrices like spices.
The LC-MS/MS system plays a pivotal role in this detection process. The liquid chromatography component separates the tetracycline from other matrix components, while the mass spectrometry portion identifies and quantifies it based on its unique molecular ions. Calibration standards are prepared to cover the expected concentration range of tetracycline residues.
The standard also includes detailed acceptance criteria for both method validation and result interpretation. Method validation ensures that the analytical procedure consistently produces accurate, precise, and reproducible results across multiple batches of samples. Acceptance criteria define acceptable limits for tetracycline detection in spices, ensuring compliance with international regulations such as those outlined by the World Health Organization (WHO) and Food and Agriculture Organization (FAO).
Our laboratory adheres strictly to the ISO 57965 standard during every aspect of this service. This commitment guarantees reliable test results that are both accurate and compliant with global standards.
Scope and Methodology
The scope of our ISO 57965 tetracycline detection in spices service extends beyond mere compliance checking; it encompasses a comprehensive approach to ensuring high-quality, safe food products. Our methodology adheres strictly to the ISO standard, which provides detailed instructions for sample preparation, derivatization, and instrumental analysis.
- Sample Preparation: Extraction of tetracycline from spices using methanol followed by solid-phase extraction (SPE).
- Derivatization: Conversion of tetracycline to its pentafluorobenzyl ester derivative for enhanced detection sensitivity.
- Instrumental Analysis: LC-MS/MS with a QqQ mass analyzer operating in positive ion mode.
The acceptance criteria specify that the method must achieve a minimum of 90% recovery at all calibration points, inter-day precision
The LC-MS/MS system used in our laboratory boasts a high sensitivity level, allowing for the detection of very low concentrations of tetracycline. The system's performance is validated through rigorous calibration and quality control checks before each analytical run. This ensures consistent and reliable results across all samples processed.
