qPCR kits for the detection and quantification of Listeria, Salmonella and E. coli strains producing shiga toxin


Listeria, Salmonella and shiga toxin-producing E. coli strains (STEC) are the most important foodborne diseases in the world. Responsible for thousands of hospitalizations, deaths, lost work days and even plant closings and recall of products from the market.

The food industry around the world requires methods and analysis tools to ensure the safety of foods offered to the market with greater certainty and speed.

Until now, traditional microbiological analysis methods (plate culture) and incipient molecular methods have been used. The former are slow (results in 3 to 7 days) and inaccurate and the latter deliver results in less than a day and with greater confidence.


  • Quality assurance of final product and intermediate products.
  • Certification and risk assurance programs in food processing plants.


  • It allows to ensure with greater certainty and speed the quality of the offered products.
  • It has internal control that ensures the integrity of the entire process.
  • Significantly faster response times.
  • It does not require investment in specific equipment.
