B.EL.D |


EMBIO Diagnostics Ltd created the B.EL.D. (Bio Electric Diagnostics), a multi-use handheld chemical analyzer that instantly tests for Listeria and other harmful chemicals in food.

Rapid Listeria Detection

Results in Minutes

Reliable detection of unwanted bacteria in fresh produce, meat and milk products within 3 minutes

Use with your phone

B.EL.D results display on your
mobile phone 

Following Standards

B.EL.D. platform automatically maintains international standards & guidelines for food management

Everything in cloud

Automatic cloud-based private data storage, categorization, historic data access and reporting


Sample Preparation Depending on Food Matrix

Inoculate 25 g or mL food sample with 225 mL of primary enrichment (Half-Fraser broth) Incubate the suspension at 30oC for 24 h.

Liquid Form Sample

Follow BELD Protocol

  1.  Sample on electrodes
  2.  Biosensors on sample
  3.  Device for measuring response

Add 20 μL of the incubated food suspension on the top of each electrode. After 60 seconds add 20 μL of the biosensors

3 MinuteS

Connection with BELD Algorithm and data analysis system

Monitor results via Mobile application or the online platform

B.EL.D Web Platform

Results from current and past tests can be retrieved and reported from the B.EL.D Web-platform

Test data can also be enhanced with sample images, geolocation, and other key data points that contribute to the enhancement of the application’s machine learning infrastructure


With the use of apps your phone is the gateway to our web platform in order to test results, access historic data and statistics and get updated with the latest features of food safety.

Patented biotechnology

Detection is powered by BERA Biosensors to acheive selective and accurate detection.

AI algorithms 

Data improves the accuracy of detection and adapts to user experience.

Cloud Platform

Our cloud platform allows storing sample images, key information for a clear view of the supply chain.

Machine Learning

With the use of ML our diagnostic platform allows for a unique view on the food supply chain. Find now what others wait days.

Our Listeria detection test

Our test has been designed to detect the presence of the pathogenic bacterium Listeria monocytogenes in milk and milk products. More than 200 tests on milk and cheese samples have been evaluated by the ISO 11290 1:2017 method, revealing 100% success rate with a Limit Of Detection of 100 CFU g-1 or mL-1 in all food substrates.*

* Biosensor’s accuracy was 90 and 91% in milk and halloumi cheese samples, respectively, when LOD was set at 4 CFU g 1 or mL-1
