A Systems Analysis Methodology to Elucidate and Evaluate the Critical Control Points for E.coli 0157:H7 in Cattle etc - OZ0708

Food poisoning is a major cause of public concern over food safety, further heightened by well publicised incidents such as the outbreak caused by Eschericia coli O157: H7 in Scotland. IN order to implement a rationale and well-targeted policy to reduce the risk of food poisoning, it is necessary to conduct an assessment of the risks and the critical control points in the production chain.
This project proposes the development of a systems analysis methodology for E. coli O157: H7 I cattle and sheep from farm to abattoir to ensure that any such risk assessment is complete and comprehensive. Using this methodology, a quantitative framework, based on causal probability networks will provide an effective method for understanding and communicating the qualitative structure of the system, and facilitate the calculation of risks across the whole network.
The resulting model will be used to identify key control points within the farm system, and estimate the risk of E. coli O157: h7 reaching the abattoir in current production systems, as far as the available data allow.
No. Description
01 Develop a systems analysis methodology for sheep and cattle production systems. Document the methodology
02 Develop a model framework of the lifecycle of E. coli O157: H7 in cattle and sheep and identify and extract the data required to quantify infection and contamination risks (qualitative and quantitative hazard identification). . Document the methodology.
03 Develop a general probability network model by quantifying the probabilities associated with those hazards and quantifying them for the general case. Apply the model to cattle critical control points and make recommendations
