This paper presents a unified analysis of dynamic producer incentive systems for
Salmonella control in primary production and slaughter plant investments in Salmonella
control measures. We identify optimal incentive system parameters and cost-effective
control strategies for achieving various levels of Salmonella prevalence. We compare
the performance measures of the combined plant-level control and producer incentive
system with results obtained under a producer incentive system only. The combined
system allocates control effort among producers and the slaughter plant, resulting in
25–83 per cent lower expected total control cost for a wide range of threshold values.
