ISO 14508 Saxitoxin Quantification in Shellfish
The quantification of saxitoxin (STX) in shellfish is critical for ensuring the safety and quality of seafood products. STX, a potent neurotoxin produced by certain species of marine algae, can accumulate in shellfish such as clams, mussels, oysters, and scallops under specific environmental conditions. The presence of saxitoxin poses significant health risks to consumers, particularly for those with pre-existing neurological conditions.
The ISO 14508 standard provides a robust methodology for the quantification of saxitoxin in shellfish. This service ensures that food safety standards are met and that products comply with international guidelines such as ISO 14508-1 and other local regulations. Our laboratory adheres strictly to this protocol, ensuring accurate and reliable results.
The process begins with the collection of shellfish samples from verified sources. These specimens are then prepared according to ISO 14508 guidelines: they are cleaned thoroughly to remove any external contaminants before being homogenized for analysis. The extraction step involves the use of acetonitrile, followed by filtration and clean-up using solid-phase extraction cartridges.
The quantification process utilizes high-performance liquid chromatography (HPLC) with fluorescence detection, which is highly sensitive and selective for saxitoxin. This technique allows for precise measurement down to parts per billion levels, ensuring accurate quantification even in trace amounts. The results are analyzed using advanced software that compares the sample data against known standards.
Our laboratory is equipped with state-of-the-art instrumentation, including HPLC systems and calibration solutions that comply with ISO 14508 specifications. Rigorous quality control measures ensure consistency and reliability of our findings. Compliance reports are generated promptly, providing clients with detailed information on saxitoxin levels in their shellfish samples.
By adhering to these stringent protocols, we provide peace of mind knowing that your products meet the highest safety standards required by global markets.
