ISO 18743 Detection of Norovirus in Oysters and Shellfish by Molecular Methods
The detection of noroviruses in oysters and shellfish is critical for ensuring food safety, particularly as these pathogens pose a significant risk to public health. Noroviruses are the leading cause of viral gastroenteritis globally and can be easily spread through contaminated foods such as shellfish harvested from polluted waters.
ISO 18743 provides a standardized method for detecting norovirus in oysters and other shellfish using molecular techniques, primarily quantitative polymerase chain reaction (qPCR). This service ensures that food safety standards are met by providing accurate and reliable detection of noroviruses. The procedure involves several key steps: sample collection from the source, transport to the laboratory under controlled conditions, preparation for testing, and finally, analysis using qPCR.
Sample preparation is crucial in ensuring the accuracy of the test results. Shellfish samples are homogenized and filtered to isolate potential pathogens effectively. The integrity of the specimen is maintained during transportation through controlled temperature conditions to prevent any contamination or degradation that could affect the testing outcome.
The qPCR method used adheres strictly to ISO 18743 guidelines, which specify precise reagent concentrations, reaction volumes, and cycling parameters for optimal sensitivity and specificity. This approach minimizes false positives while ensuring high detection rates even at low viral loads.
Upon completion of the test, results are reported promptly with a detailed analysis including cycle threshold (Ct) values indicating the relative amount of norovirus present in each sample. Reporting also includes information on the standard operating procedures followed and any deviations from expected outcomes, allowing for transparency and reproducibility.
The implementation of ISO 18743 ensures that laboratories adhere to stringent quality control measures, maintaining high standards of accuracy and precision. This service is particularly beneficial for food safety programs aimed at preventing outbreaks associated with contaminated shellfish products.
In summary, the application of ISO 18743 in detecting norovirus in oysters and other shellfish by molecular methods provides a robust framework for ensuring public health protection through accurate detection techniques. The meticulous processes involved in sample preparation, testing, and reporting contribute significantly to meeting regulatory requirements and enhancing consumer confidence.
