ISO 14189 Vibrio Detection in Shellfish Validation Method Development Test
The ISO 14189 standard provides a framework for quality management systems in laboratories. This service focuses on the validation of methods used to detect Vibrio spp., particularly relevant to shellfish safety and compliance with regulatory standards such as FDA, EU, and WHO guidelines.
The detection of Vibrio spp. is crucial in the food sector due to their potential to cause gastrointestinal illness, especially when present in seafood products. This validation method development test ensures that the laboratory's testing methods are accurate, reliable, and capable of detecting even low levels of these pathogens.
The process involves several critical steps: sample collection from shellfish beds, transportation under controlled conditions, preliminary screening using rapid diagnostic tests, followed by confirmatory culture-based techniques. The validation test aims to ensure that the final method is robust enough for routine use in food safety testing.
- Sample Collection: Fresh samples are collected directly from the shellfish beds where they were harvested. This ensures that the sample represents the actual environment and potential contamination levels.
- Preliminary Screening: Rapid tests such as lateral flow assays or PCR-based methods provide a quick first line of defense, indicating whether further testing is necessary.
Once preliminary screening indicates the presence of Vibrio spp., the culture-based method is used for confirmation. This involves inoculating media suitable for growth of Vibrio spp. and incubating under conditions that favor their proliferation.
| Methodology Step | Description |
|---|---|
| Sample Collection | Fresh samples are collected from the shellfish beds and transported to the laboratory under controlled conditions. |
| Preliminary Screening | Rapid diagnostic tests such as lateral flow assays or PCR-based methods are used for initial identification of Vibrio spp. |
| Culture-Based Confirmation | Inoculated media suitable for growth of Vibrio spp. are incubated under appropriate conditions. |
Scope and Methodology
This section details the scope of the ISO 14189 Vibrio detection method validation service, emphasizing its relevance to shellfish safety. The primary focus is on ensuring that the testing methods meet international standards for accuracy and reliability.
