Eliciting expert opinion on the effectiveness and practicality of interventions in the farm & rural environment to reduce human exposure to Escherichia coli O157
The need to mitigate and manage diseases has prompted the use of various expert consultation and opinion elicitation methods. We adapted Best-Worst Scaling (BWS) to elicit experts’ assessment of the relative practicality and effectiveness of measures to reduce human exposure to E. coli O157. The use of two criteria (practicality and effectiveness) was carried out within the BWS process. Cattle vaccination was considered the most effective and hand-washing was considered the most practical.
