Purpose: The research described in this paper is aimed at developing a model for estimation of performance objectives (PO) in the supply chain, based on field data. As a case study, such a model has developed for Salmonella prevalence in the broiler supply chain in the Netherlands.

Methodology/approach: Food safety in the supply chain can be controlled by the application of performance objectives (PO) in the chain. A PO in the final product is pre-set, and translated into PO at previous points of the chain. Applying this concept, an analytical model has been developed for estimation of PO for Salmonella in the broiler supply chain, based on a preset PO in the finished product (end processing). Model development was based on monitoring data on Salmonella prevalence at five sampling points in the chain, covering all slaughterhouses in the Netherlands in the period 2002-2005.

Findings: Reducing the end PO from the reference situation of 2.5% to 1.5% may be practical achievable, but interventions are needed at each stage. An end PO of 0.5% or lower needs substantial effort in all stages, but particularly at the slaughterhouse.

Practical implications: Modeling PO in the supply chain based on monitoring data helps to establish realistic food safety targets and to estimate the effects of potential intervention measures to reduce the end-PO. The developed model is easy to understand by policy makers, and helps to focus on those points in the supply chain that need further attention.
