BAX® System SalQuant

A Method to Quantify Salmonella

In addition to knowing if Salmonella is present, Hygiena is pioneering diagnostics with the ability to quantify Salmonella at critical control points using BAX® Q7 and our BAX® System Real-Time Salmonella Assay.

This data is used to monitor levels of Salmonella and identify changes over time, enabling plant managers to utilize data to track Salmonella problem areas for rapid corrective action.

In this Webinar:

  • Why SalQuant, a more cost-effective, real-time PCR quantification method is quickly replacing old-school MPN’s and culture methods
  • New ways leading poultry processors are using statistics to increase confidence in food safety decisions
  • How to conduct quantitative bio mapping assessments cost-effectively
  • Tips to shorten response times to Salmonella and CCP failures, from the identification of problems to corrective actions
  • How to get actionable production and food safety data, quicker, to improve throughput, and yield




SalQuant vs MPN

BAX® System SalQuant is used to monitor levels of Salmonella and identify changes over time and provides same day actionable results.

This method provides a more accurate and precise estimation of Salmonella when compared to Most Probable Number (MPN) methods, which don't quantify levels of bacteria and can't determine where contamination may be located.
