Challenge Studies

A challenge study consists in the artificial contamination of the food with the target microorganism under controlled experimental conditions.

These studies are intended to determine whether an RTE food is able to support the growth of L. monocytogenes or not during the designated shelf-life.

Challenge Studies in Mérieux NutriSciences

Our scientific experts use predictive microbiology to gather all theoretical approaches aiming to predict the growth profile of a microorganism in the conditions chosen by the operator.

This approach associates a growth profile with each combination of intrinsic (i.e., pH, water activity, preservatives) or extrinsic (i.e., humidity, light, temperature) parameters.

Our predictive services can help you to:

  • Create a new product or change the formulation of an existing one
  • Evaluate product spoilage or pathogenic risks
  • Limit costs and time of experimental studies with better-targeted analyses
  • Determine optimum microbiological safety intervals and critical points to integrate in the HACCP process
