ISO 21567 Shigella Detection Test in Water
The ISO 21567 standard provides a robust framework for detecting Shigella bacteria in water samples, which is crucial for ensuring the safety of drinking and wastewater. This test is essential due to the potential health hazards associated with the presence of these pathogens. Shigella species are known to cause shigellosis or bacillary dysentery, leading to symptoms such as diarrhea, fever, and abdominal cramps.
The ISO 21567 protocol involves several steps that ensure accurate detection. The first step is collecting a representative water sample from the source where contamination might occur. Proper sampling techniques are vital to avoid bias in results. Once collected, the sample undergoes preliminary processing, which includes homogenization and dilution.
The most critical part of this process involves inoculating enrichment broths or plating onto selective media that favor Shigella growth over other bacteria. Following incubation at specific temperatures (typically 35°C), colonies suspected to be Shigella are identified using biochemical tests and serological methods.
The ISO 21567 protocol emphasizes the need for high-quality laboratory practices, including personnel training, standard operating procedures, and quality control measures. Laboratories must adhere strictly to the guidelines provided in this international standard to ensure consistent results across different facilities.
Shigella detection is not just a technical exercise but also carries significant public health implications. Drinking water contaminated with Shigella can lead to widespread outbreaks, particularly in areas where sanitation and hygiene are poor. Therefore, regular monitoring using tests like ISO 21567 is necessary for maintaining public health standards.
In wastewater treatment plants, the presence of Shigella could indicate inadequate disinfection processes or improper management practices. Detecting these pathogens early allows for timely interventions to prevent their spread into the environment and water systems.
| Step | Description |
|---|---|
| Sample Collection | Collect representative samples from potential contamination sources. |
| Preliminary Processing | Homogenize and dilute the sample for accurate analysis. |
| Inoculation | Inoculate enrichment broths or use selective media to grow Shigella. |
| Incubation | Incubate samples at 35°C for optimal growth. |
| Identification | Identify colonies using biochemical tests and serological methods. |
The ISO 21567 protocol ensures that the detection of Shigella is both reliable and reproducible, making it an indispensable tool in water quality control. By adhering to this standard, laboratories can contribute significantly to public health by ensuring that water supplies are free from harmful pathogens.

Use Cases and Application Examples
- Drinking Water Supply: Ensuring the safety of drinking water by detecting Shigella early in the supply chain.
- Wastewater Treatment Plants: Monitoring wastewater to prevent contamination from entering natural water bodies.
- Healthcare Facilities: Preventing cross-contamination within hospital settings where Shigella could pose significant risks.
Water samples are often collected at various stages, including raw water intake, treated water before distribution, and wastewater. By implementing ISO 21567 testing protocols, these facilities can ensure that any contamination is identified promptly, allowing for corrective actions to be taken swiftly.
A real-world example would involve a municipal water supplier who conducts regular ISO 21567 tests on its raw water intake. If Shigella is detected, the source of contamination can be traced and addressed immediately. This proactive approach ensures that by the time treated water reaches consumers, it has been thoroughly tested for safety.
