Salmonella predictions

An Excel add-in to predict Salmonella spp. in food environments

The Salmonella_Predictions.xls Excel add-in has been developed at the Institute of Food Research, Norwich, UK under European funding (BIOTRACER project). The software is a complementing tool for bio-tracing in the pork chain by predicting the dependence of Salmonella concentration on the environment.

Probabilistic and kinetics models are combined to give predictions on the concentration of Salmonella spp. at any stage of the pork chain under fluctuating pH, Aw and/or temperature. Predictions can be obtained between 0-30°C, 2.5 - 7 pH  and 0.78-1 for Aw. Data to fit the models were obtained from the ComBase database.
