Purpose: To present new predictive models and new features included in the FSSP software to be released in 2014.
Methods: FSSP has been developed for MS Windows by using the object-oriented programming language C# and this allowed convenient addition of new models and facilities to the software. FSSP can be used in 18 different languages.
Results: New models in FSSP include:
(i) Extensive growth and growth boundary model for lactic acid bacteria (LAB) in seafood and meat products.
(ii) Expanded model to predict the simultaneous growth of LAB and L. monocytogenes in various seafood and meat products. This new microbial interaction model includes the effect of 12 environmental parameters and predictions can be obtained for constant or for dynamic temperature storage conditions.
(iii) Generic growth and growth boundary model. This is a simplified cardinal parameter type model that allows users to predict growth and growth boundary for any microorganism where the cardinal parameter values are known. The generic model can take into account the effect of up to 12 environmental parameters and predictions can be obtained for constant or for dynamic temperature and pH storage conditions.
Significance: The FSSP software facilitates assessment and management of microbiological risks in food and becomes available for free from http://fssp.food.dtu.dk.
