Ms Titus addressed the need to determine the safety of pork chops produced in New Zealand. To this end, she developed a novel suite of quantitative, mathematical models. These models described and evaluated the likelihood that three potentially destructive bacteria were present on pork chops sold at retail outlets in New Zealand. Using these models, Ms Titus also investigated possible efficacious methods to reduce these pathogen numbers on pork chops. The models predicted distributions of bacteria concentrations and prevalence, while the model development process facilitated an increased understanding of pathogen dynamics occurring in the pork food chain. This suite of models can be adapted for use by government agencies in New Zealand.
