ISO 21871 Detection of Vibrio cholerae Non-O1 and Non-O139 in Seafood
The International Organization for Standardization (ISO) has developed the ISO 21871 standard, which provides a method for detecting the presence of Vibrio cholerae non-O1 and non-O139 serotypes in seafood samples. This is crucial for ensuring public health and food safety as these serotypes can cause severe illness including diarrhea, dehydration, and even death if left untreated.
The standard specifies a comprehensive approach to sampling, sample preparation, culture conditions, and enumeration of viable cells using selective media. The test requires strict adherence to laboratory protocols to ensure accurate detection and reporting. Compliance with this ISO standard is mandatory for seafood processors, distributors, retailers, and food safety agencies worldwide.
The primary goal of the ISO 21871 test is to identify potential hazards early in the supply chain so that preventive measures can be taken before products reach consumers. This service ensures that seafood products meet international quality standards set by regulatory bodies like the Food and Agriculture Organization (FAO) and World Health Organization (WHO).
Our laboratory employs highly skilled microbiologists who use advanced microbiological techniques to carry out this test. We also utilize state-of-the-art equipment such as automated colony counters, high-performance liquid chromatography (HPLC), and other relevant instruments to ensure precise results.
| Parameter | Description |
|---|---|
| Sampling Procedure | Involves collection of representative samples from various stages of processing, transportation, and storage to ensure no bias in results. |
| Sample Preparation | This includes homogenizing the sample followed by appropriate dilutions depending on expected concentration levels. Proper aseptic techniques are used throughout this process. |
| Selective Media Usage | The use of specific media like TCBS agar which supports growth only of V. cholerae non-O1 and non-O139 strains while inhibiting other microorganisms present in the sample. |
| Incubation Conditions | Standardized incubation temperatures (typically 37°C) under controlled atmospheric conditions for optimal growth of target organisms. |
| Enumeration Method | Viable cell counts are determined using colony-forming unit (CFU)/g or CFU/mL units after incubation period. This allows quantification of the pathogen load within the sample. |
