Model Helps Identify Best Salmonella Interventions

NETHERLANDS - Researchers at Wageningen University have developed a model to improve control of Salmonella in the poultry meat supply chain.

S.O. Tromp of the Wageningen University and Research Centre and colleagues have published a paper in a forthcoming issue of Risk Analysis on their work to develop a model for setting performance objectives for Salmonella in the broiler supply chain.

They explain that they have developed a stochastic model for setting performance objectives for Salmonella in the broiler supply chain. The goal of this study was to develop a model by which performance objectives for Salmonella prevalence at various points in the production chain can be determined, based on a preset final performance objective at the end of the processing line.

The transmission of Salmonella through the broiler production chain was modeled.

The prevalence at flock level was calculated from the measured prevalence at sample level. The transmission model is based on data on the occurrence of Salmonella collected in the Dutch broiler production chain during several years.

The Wageningen researchers' model can be used by policy-makers and industry to determine economically and politically acceptable performance objectives for various points of the production chain and to draw conclusions about which interventions are most appropriate.
