MCRA: Monte Carlo Risk Assessment

This website hosts MCRA version 7.1, which can be used for single-compound dietary assessments.
Soon this website will be upgraded to version 8.0. MCRA 8.0 for cumulative and aggregate assessments can currently be accessed at
MCRA 8 .

Probabilistic modelling of chemical intake from food


MCRA quantifies dietary exposure to chemicals as a distribution
by combining data on food consumption with data on concentrations of chemicals in foods.

Analyze your own or shared data on consumption and chemical concentrations.

Main features of MCRA are:
  • Data selection from e-platform of MS Access databases, or from a simple MS Excel table
  • Conversion of food-as-eaten to food-as-measured, model for brand loyalty
  • Quantification of short-term exposure (personday intake) for acute risk assessment
  • Quantification of long-term exposure (usual intake) for chronic risk assessment
  • Relative contributions of foods to the total exposure/intake
  • Modelling of exposure/intake as a function of covariates, e.g. age and gender
  • Modelling of concentrations, including models for nondetects and unit variability
  • Modelling of food processing effects
  • Uncertainty analysis
  • For acute risks comparison with external point estimates

MCRA is a program for Monte Carlo Risk Assessment, developed for RIVM by WUR/Biometris to facilitate RIVM's tasks for the national food safety authority ( VWA ) and for cooperation in international projects ( EFSA , EC Research ). MCRA started in the context of the Dutch Programme for the Quality of Agricultural Products ( KAP ).
