The objective of this paper is to explore the cost effectiveness of different control scenarios against Salmonella
in the Dutch pork chain to determine the most promising scenarios. Multiple scenarios were analysed, whereas each scenario included the epidemiological and economic consequences of interventions in the pork chain on the separate stages and on the pork chain as a whole. The first conclusion is that with respect to the prevalence reduction in the stages, the lairage stage seems to be most cost-effective. The second conclusion is that the most cost-effective strategy for the pork supply chain is to implement interventions in the first place in the slaughterhouses and also in the finishing farms. The third conclusion is that the cost-effectiveness is reduced in case not all farms or firms within a particular stage participate in reducing the prevalence of Salmonella. The most effective strategy with respect to the reduction of Salmonella will be to include the transportation and lairage in the Salmonella control
program, since these stages may become more important when the largest problems are solved in the finishing and
slaughter stage. The results of this paper give the first insight in the promising scenarios. In further research,
these scenarios have to be examined in more detail and can subsequently put into practice.
