EN ISO 19020 Rapid Real-Time PCR Detection of Yersinia enterocolitica in Meat Products
The European Standard EN ISO 19020 outlines a rapid real-time polymerase chain reaction (PCR) method for detecting Yersinia enterocolitica, a pathogen that can cause gastrointestinal and systemic symptoms in humans. This service is crucial for ensuring the safety of meat products by identifying potential contamination early, thus protecting public health.
The process begins with the collection of samples from various parts of the meat product, including the surface and internal portions. The specimens are then prepared according to strict protocols outlined in EN ISO 19020 to ensure accurate and reliable results. Next, the DNA is extracted using optimized techniques designed to minimize cross-contamination.
The real-time PCR method employed for this service involves specific primers and probes that target unique sequences within the bacterial genome of Yersinia enterocolitica. This technology allows for rapid amplification and detection of the pathogen, providing results in a matter of hours rather than days. The assay is highly sensitive, detecting as few as 10 CFUs/mL in complex matrices like meat.
The equipment used includes state-of-the-art real-time PCR machines capable of performing precise measurements at molecular levels. These instruments are calibrated regularly and maintained according to international standards to ensure accuracy and reliability. The data obtained from the PCR reaction is analyzed using dedicated software, which calculates the cycle threshold (Ct) value for each sample.
Based on predefined cut-off points derived from the standard, the results are classified into positive or negative categories. Positive samples indicate the presence of Yersinia enterocolitica, prompting immediate action to prevent contamination in production lines or batches. Negative results ensure that products can be released for consumption with confidence.
| Sample Type | Detection Limit (CFU/mL) | Reporting Threshold (Ct Value) |
|---|---|---|
| Meat Juice Extracts | 10 CFU/mL | Ct ≤ 34.5 |
| Solid Meat Samples | 10^2 to 10^3 CFU/g | Ct ≤ 36.8 |
The service adheres strictly to EN ISO 19020, ensuring that all aspects of the testing process meet or exceed international quality standards. This commitment guarantees accurate and reliable results, which are essential for maintaining consumer trust and compliance with regulatory requirements.
