The increasing rate of food recalls issued by federal regulatory agencies, and what that might imply about the current systems for outbreak investigation and disease surveillance
How federal and state public health agencies conduct foodborne illness outbreak investigations and the current success rates of these investigations
Elements of the foodborne illness outbreak investigation process that are working well
Potential areas for improvement for foodborne illness outbreak investigations and the metrics for "success"
