Listeria species and Listeria monocytogenes testing solutions

The detection of Listeria in foods before they are consumed is vital for safeguarding public health and essential for preserving the financial health and reputation of food businesses. When performing testing, the presence of Listeria species is often considered indicative that pathogenic Listeria monocytogenes may also be present. Therefore, when ensuring that Listeria monocytogenes is absent or present below a certain level in tested samples, the strategy often involves the detection of Listeria  species in general. We offer a wide range of products and solutions for the detection, enumeration, and identification of Listeria in foods and associated sample types.

Reference methods

Featured solutions

Reduce the risk of human error in your PCR-based Listeria testing

Mistakes in your PCR workflow can lead to false-positive or false-negative results, compromising the accuracy and reliability of the test. With the Thermo Scientific SureTect Automation Workflow you can take your PCR-based Listeria testing to the next level with automated lysis and PCR setup. Utilizing the CyBio FeliX Instrument, the automated workflow allows you to reduce hands-on time while increasing the accuracy and reproducibility of results.

Streamlined Listeria enumeration                                 

A recent addition to the Listeria Precis Enumeration Workflow, our bottle format is designed specifically for pour plating, exhibiting equivalence to the ISO 11290-2:2017 reference method and providing up to 10x increased sensitivity, allowing you to accurately detect even the lowest levels of contamination. Unlike surface-plating methods that need three plates to achieve necessary sensitivity, pour plating uses a single plate per sample, saving on costs.
