The present risk assessment was created as part of a study to assess the public health risk due to Listeria monocytogenes in Australian made processed meat products, more specifically lunch meats, pâtés/liverwursts and cooked sausages. The model predicts the concentrations of L. monocytogenes on products at the time of consumption using industry and other survey data augmented by predictive microbiology models. The model performs calculations in seven stages: 1. Storage at the processing plant; 2. Transport: Processor to Retail Distribution Centre; 3. Storage at Retail Distribution Centre; 4. Retail Display; 5. Transport: Retail – Consumer. 6. Storage by Consumer (Package unopened) and; 7. Consumer by Consumer after Package opened.

The stochastic model was developed using @Risk. To view the complete model you must have the @Risk software installed in your computer. For a free trial or to purchase this program go to http://www.palisade.com/risk/.

If you do not have @Risk installed in your computer you can still view the model; however you will not be able to see the @Risk functions used by the model.
