Industry Problems

Food Industry main problems in Quality Control are caused byFood Industry main problems in Quality Control are caused bySlowness in obtaining the results which causes a delay in the release of analyzed products

Lack of personnel trained to perform PCR‐based analyses

Quality Control costs are highQuality Control costs are highDue to the high number of hours of personnel required per analysis

Due to long time to market product readiness

Pathogens in food samples are usually hard to detect since ththey arePresent at low levels, with accompanying bacterial flora

Quiescent due to thermal, radiation, freezing treatments…

Microbial efforts are exclusively directed to research,development, and production of new tools for the detectionof pathogenic bacteria by PCR

Years of experience help in identifying the best genetic targets, andin the design of the appropriate molecular tools to detect them

Quality is our main goal

Our analysis systems are based on years of rigorous investigations, and on the application of the characteristics and conditions that a good molecular target must accomplish. 

This has lead us to present a product which goes a step forward in the detection of food‐borne pathogens.
