The USDA Integrated Pathogen Modeling Program - Dynamic Prediction (IPMP - Dynamic Prediction)

What is IPMP-Dynamic Prediction?

IPMP-Dynamic Prediction is an extension of the USDA Integrated Pathogen Modeling Program (IPMP). It is designed to simulate and predict microbial growth and inactivation under dynamic conditions. It differs from IPMP, which is design to analyze individual growth or inactivation curves. IPMP-Dynamic Prediction is used to predict the growth and inactivation of microorganisms exposed dynamically-changing temperature and other environmental conditions. A typical application of IPMP-Dynamic Prediction is predicting the growth of Clostridium perfringens in cooked meats during cooling.


What is required to use IPMP-Dynamic Prediction?

IPMP-Dynamic Prediction can be run under Microsoft Operating Systems (32 or 64 bit).

What models are included in IPMP-Dynamic Prediction?

IPMP-Dynamic Prediction has one model now for dynamic prediction of growth of C. perfringens in cooked beef during cooling.  It will be expanded gradually to include more models.
