ISO 21871 Shiga Toxin-Producing E. coli Detection in Feed
The detection of Shiga toxin-producing E. coli (STEC) in agricultural and animal feed is critical for ensuring food safety, particularly because certain strains can cause severe health issues including bloody diarrhea, kidney failure, and even death. This service focuses on the ISO 21871 standard which provides a robust methodology for detecting STEC in feed products. The presence of these pathogens in animal feed not only poses risks to livestock but also affects human health through the food chain.
The detection process involves multiple steps, starting with sample collection and preparation, followed by enrichment culture, isolation, and finally confirmation using a combination of biochemical tests and PCR-based methods. This multi-step approach ensures accurate identification and differentiation between various E. coli strains. The ISO 21871 standard emphasizes the importance of preventing contamination in feed production to protect both animal health and consumer safety.
The significance of this service extends beyond just compliance with regulatory standards; it plays a pivotal role in safeguarding public health by minimizing the risk of foodborne illnesses. By adhering to this stringent testing protocol, laboratories can help ensure that agricultural products meet the highest quality standards and are safe for consumption.

Why It Matters
The significance of detecting Shiga toxin-producing E. coli (STEC) in feed cannot be overstated, especially given its potential to cause serious health problems such as hemolytic uremic syndrome (HUS), which can lead to kidney failure and other severe complications. The presence of these pathogens in animal feed can have far-reaching consequences not only for livestock but also for human health through the food chain.
STEC contamination poses significant risks both for animals consuming the infected feed and consumers who ultimately eat meat or dairy products derived from those animals. For instance, STEC O157:H7 has been linked to numerous outbreaks worldwide that resulted in hospitalizations and fatalities. Ensuring that feed is free from these dangerous bacteria is crucial not only for protecting animal welfare but also for safeguarding public health.
Compliance with international standards like ISO 21871 goes beyond merely meeting regulatory requirements; it demonstrates a commitment to maintaining the highest levels of quality assurance and safety. Adhering to this standard ensures that all testing methods used are consistent, reproducible, and reliable across different laboratories worldwide. This consistency is essential for building confidence among consumers, regulators, and other stakeholders.
Furthermore, implementing ISO 21871 helps mitigate the financial impacts associated with potential recalls or lawsuits due to foodborne illness outbreaks. By proactively identifying and addressing contamination issues early on, companies can avoid costly disruptions to their operations while also preventing reputational damage that could undermine consumer trust.
In summary, detecting Shiga toxin-producing E. coli in feed is essential for protecting both animal health and human safety. By following the rigorous protocols outlined in ISO 21871, laboratories like ours contribute significantly to maintaining food security and promoting sustainable practices within the agricultural industry.
Scope and Methodology
| Step | Description | Justification |
|---|---|---|
| Sample Collection and Preparation | Collect samples from feed batches using aseptic techniques. Transfer to appropriate containers for transport to the laboratory. | To ensure that the sample represents the entire batch accurately, minimizing any potential biases. |
| Enrichment Culture | Cultivate samples in suitable media conducive to growing STEC. This step enhances bacterial concentration for easier detection. | An increase in bacterial numbers improves the likelihood of isolating target organisms from complex matrices like feed ingredients. |
| Isolation and Identification | Use selective media to isolate suspected STEC. Confirm identity through biochemical tests and serotyping if necessary. | Specific identification ensures accurate classification, distinguishing harmless E. coli from those capable of producing shiga toxins. |
| PCR-Based Detection | Perform polymerase chain reaction assays targeting specific genes associated with shiga toxin production. | This rapid method provides definitive proof of STEC presence without culture dependency, reducing false negatives. |
