摘要：The relation between the moment at which a recall of Dutch custard is initiated and the direct costs of this recall was investigated. A simulation model of the custard supply chain was developed to compare scenarios with and without a quarantine of 48 h at the storage of the production plant. The model consists of three parts; first the distribution of a 24,000 L batch of custard over the supply chain over time is simulated, second the time to detect spoilage bacteria with a recontamination test procedure is simulated, third the direct recall costs of custard over the different parts of the supply chain are calculated. Direct recall costs increase from about €25,000 per batch to €36,171 from 57 to 135 h in the situation without quarantine and from €25,000 to €36,648 from 123 h to 163 h for the situation with quarantine. Then costs decrease, because more and more custard is at the consumer level and only 0.13% of the consumers will ask for a refund. With low true contamination probabilities quarantine is not profitable, but at later detection moments with high probabilities it is. We conclude that a simulation model is a helpful tool to evaluate the efficiency of risk management strategies, like end-product testing and a quarantine situation.
