Grow, Read, Detect.

The CERTUS System provides real-time monitoring
through simultaneous enrichment and detection.

The CERTUS System

The CERTUS System is uniquely positioned for the end user working in a small to mid-size food production facility.

Utilizing the exceptionally accurate, rapid, and easy to use bio-contained Listeria spp. detection system, you are partnering with a dedicated staff of scientists who are ready to answer questions and help you on your continuous improvement path.

Our goal is to empower you so you can control your environmental sampling program, turnaround time, and costs. With the ability to detect Listeria spp. from most surfaces, the CERTUS system allows you to perform: analysis, hygiene remediation of presumptive positive test sites, documentation and reporting - all conveniently managed and easy to use.

Simple, Safe, Smart Pathogen Detection

Simplified Workflow

Our goal is to empower you so you can to control your environmental sampling program, turnaround time, and costs. With 3 simple steps to test results, anyone can quickly perform environmental monitoring with the CERTUS System.

Bio-Contained System

Confidently perform pathogen detection in-house with CERTUS’s fully bio-contained system.

The Bio-Lock Sampling Swab secures the environment from accidental contamination and enables you to move testing onsite for significantly faster results and reduced costs with no need for a laboratory or complicated technical training.

Real Time Monitoring

Grow, Read, Detect provides real-time monitoring which means as soon as the pathogen is enriched to a detectable level, continuous surface enhanced raman spectroscopic (SERS) reading of the samples provides immediate detection. The CERTUS System then sends instant alert messages to key stakeholders via text and email allowing for prompt remediation.

All in-one. All in-house.

With the ability to detect Listeria spp. from most surfaces, the CERTUS system allows you to perform: analysis,  hygiene remediation of presumptive positive test sites, documentation and reporting – all conveniently managed and easy to use.


Collect Sample

With the CERTUS System, preparation is easy and requires no specialized expertise or equipment.

Using your Bio-Lock™ Sampling Swab, swipe the surface of the day’s predetermined testing location. Then pour the pre-measured selective growth media from your kit into the Detection Tube.


Perform Test

To ensure simplicity in the workflow, the CERTUS System includes a Control Pad and software to guide the user through the testing process.

Once your sample is collected, insert the Detection Tube into the Detection Unit. Then simply click “Start Test,” and let the CERTUS technology work for you.


Get Results

The CERTUS Grow, Read, Detect™ process utilizes patented CERTUS technology for simultaneous enrichment and detection – which means fast, accurate results for you!

Real-time monitoring with fast time to a positive result empowers you with early notification of contamination and allows for prompt remediation. In the event of a positive result, notification instantly alerts stakeholders in a variety of ways including email and text.

Detection Kit

CERTUS's consumable test kits contain everything you need for safe, in-house environmental monitoring. Test kits are pathogen-specific and negate the need for purchasing separate swabs, stomacher bags, media, controls, pipettes, centrifuge, incubators, etc.

Detection Kits include Bio-Lock™ Sampling Swabs, Detection Tubes with pathogen-specific reagent dry-down particles, and pre-measured selective growth media.

Control Pad

CERTUS provides state-of-the-art technology to help you achieve your compliance goals. We understand your need to monitor your production environment for pathogenic organisms. All together, the CERTUS System offers fast, responsive and an intuitive experience for any member of your team.

We understand that while complex microbiology and sophisticated engineering form the basis of our products, any person in your organization will be able to pick up the Control Pad and start testing samples without the need for long trainings, special equipment or complicated user manuals. We've designed the CERTUS system with this in mind; that all users will be able to pick up the seamlessly integrated Control Pad and go.

Includes 9.7 inch iPad Pro and CERTUS software.

Detection Unit

The CERTUS Detection Unit features a Grow, Read, Detect™ process that allows for simultaneous enrichment and detection. This revolutionary machine provides quick, accurate, in-house pathogen detection capabilities for food processing plants.

All sample site, date, result and remediation records are permanently stored on the CERTUS System to provide instant reporting and FSMA compliant data sets.

CERTUS’s proprietary technology makes food pathogen testing quick and simple - allowing you to maximize efficiency in your plant and increase safety for consumers.

The CERTUS System Technology

CERTUS Detection Tubes are agitated horizontally in a temperature-controlled chamber that is optimal for the incubation of the selected pathogen species.
A magnetic field is engaged to the Detection Tubes to form a pellet composed of bacteria “sandwiched” between antibodies conjugated to both magnetic and SERS particles.
Each tube is interrogated by a laser hitting the pellet to elicit a Raman spectra. The strength of the Raman spectra is proportional to the bacterial load and a proprietary algorithm monitors pathogen presence and growth versus time. 
The CERTUS System can accurately detect target pathogen as enrichment is taking place thus enabling faster time to result.

Research & Development

The CERTUS pathogen detection system was designed and developed through strategic collaborations. The core SERS technology and instrument design is based on innovative technology exclusively licensed from BD (Becton, Dickinson and Company) for applications in the food safety market.

Assay reagent and media development is conducted in collaboration between CERTUS and UK-based Solus Scientific. Solus has proven scientific expertise in the development of immunoassay-based tests specific for the food pathogen testing market with their own line of AFNOR and AOAC validated ELISA tests and applies that industry expertise and scientific integrity to the CERTUS system.


CERTUS’s homogenous no-wash assay format allows for real time detection of Listeria as shown to the left where signal is plotted versus time in culture. Pre-measured selective growth media is provided with the Detection Kit.

The capability of the CERTUS System to simultaneously grow and detect Listeria spp. allows for early identification of problem environmental sites.


The road map of CERTUS product development in the short term is to expand the menu of environmental targets to include Salmonella and shiga-toxin producing E. coli (STEC).

Longer term, CERTUS will expand its product line to include food matrices.


CERTUS technology is covered under an exclusive license from BD (Becton, Dickinson and Company) for the commercialization of food safety products based on SERS nanoparticle technology, which has utility across many monitoring and diagnostic applications.

BD’s exclusive license to CERTUS also includes technology to enable pathogen detection in a bio-contained tube during enrichment so that the facility where the testing is conducted is not exposed to enriched pathogens.

BD continues to work with partners to further develop the SERS technology and is currently the supplier of SERS nanoparticles used in CERTUS products.

The CERTUS System provides plants with the tools and information needed to take appropriate action leading to sustainable growth and profitability.
