ISO 11290-1 Detection of Listeria Monocytogenes Test in Environment
The ISO 11290 series is a set of standards specifically designed to provide methods for the detection and enumeration of Listeria monocytogenes in various environments. This standard, particularly ISO 11290-1, focuses on the initial detection phase using enrichment culture techniques followed by confirmatory tests.
The importance of detecting Listeria monocytogenes cannot be overstated. Listeriosis is a severe foodborne illness caused by infection with this bacterium and can lead to serious health issues, especially in pregnant women, newborns, the elderly, and individuals with weakened immune systems.
The ISO 11290-1 method involves several critical steps:
- Pre-enrichment: The specimen is first incubated in a medium that supports the growth of Listeria monocytogenes.
- Enrichment: After pre-enrichment, the sample undergoes further incubation to enhance the concentration of the target bacteria.
- Isolation and Identification: Suspected colonies are isolated on selective media and identified using biochemical tests or molecular techniques.
- Confirmation: Positive isolates are confirmed by serotyping, PCR, or other methods as per ISO 11290-2.
The entire process is meticulously documented to ensure reproducibility and traceability. Compliance with these standards ensures that the testing laboratory adheres to internationally recognized protocols, enhancing credibility and reliability of results.
| Step | Description |
|---|---|
| 1. Pre-enrichment | Growth medium is incubated at 25°C for 24 hours. |
| 2. Enrichment | The enriched broth is incubated at 30°C for a further 24 hours. |
| 3. Isolation and Identification | Suspected colonies are isolated, identified using biochemical tests. |
| 4. Confirmation | Positive isolates are confirmed by serotyping or PCR. |
The ISO 11290-1 method is widely used in the food industry to ensure product safety and compliance with regulatory requirements. It is also applicable in other sectors where environmental hygiene is critical, such as healthcare facilities and laboratories.
For accurate and reliable results, it is essential that the testing laboratory adheres strictly to these protocols. This includes using appropriate media, incubation conditions, and ensuring personnel are trained to handle pathogens safely and effectively.
