ISO 11290-2 Listeria monocytogenes Enumeration Testing
The ISO 11290-2 standard provides a robust framework for enumerating Listeria monocytogenes, an important pathogen in the food industry. This service is critical for ensuring compliance with international safety standards and reducing the risk of contamination in processed foods, ready-to-eat products, and dairy goods. The enumeration process plays a pivotal role in preventing outbreaks that can lead to severe health implications.
The Listeria monocytogenes bacterium poses significant risks as it is capable of growing at refrigeration temperatures, making it particularly dangerous for food safety. This service supports the identification and quantification of this pathogen in various food matrices, providing a crucial tool for quality management teams to maintain product integrity.
The testing process begins with sampling, where representative samples are collected from production lines or storage facilities using aseptic techniques. Samples may include raw materials, intermediate products, final packaged goods, and environmental swabs. Once collected, the samples undergo rigorous pretreatment steps that involve homogenization, dilution, and plating to ensure accurate enumeration.
The ISO 11290-2 method involves a series of selective enrichment broths designed specifically for Listeria species, which enhance recovery rates. After incubation, the samples are plated onto selective media such as tryptose soy broth (TSB) or McConkey agar to further differentiate and enumerate Listeria monocytogenes. This selective process ensures that only the target pathogen is identified, minimizing false positives.
The enumeration process culminates in the isolation of colonies on selective media, which are then counted under standardized conditions. The final step involves confirmation using biochemical tests or molecular techniques to ensure accurate identification and quantification of Listeria monocytogenes.
This service is not only essential for compliance with ISO standards but also supports continuous improvement in food safety practices. By identifying the presence and levels of Listeria monocytogenes, businesses can implement targeted interventions to reduce contamination risks, thereby protecting public health.
Our laboratory adheres strictly to the ISO 11290-2 protocol, ensuring accurate and reliable results that are crucial for maintaining product quality and safety. Our team of experts ensures that every step of the process is meticulously executed, from sample collection to final enumeration, providing you with confidence in your food safety protocols.
