Food supply chains are constantly challenged by food safety hazards entering the chain. The ability of the supply chain to provide safe food within a reasonable time after such a food safety threat or shock can be investigated with the concept of resilience using food safety as an indicator. Resilience is then defined as the food safety performance deviation due to the shock and takes both the severity of the shock as well as the time to fully recover or reach a new equilibrium into account. This study developed a stochastic simulation model to evaluate the resilience of the Dutch pork supply chain to dioxin contamination in the feed. The resilience of the supply chain as well as the potential costs associated with the contamination are compared between several monitoring strategies with the aim to determine the optimal control points for dioxin monitoring. Model results show that collecting and analyzing samples at more than one control point along the pork supply chain, in particular at feed mills and fat melting facilities, resulted in the highest resilience and the lowest costs after a shock. This model and these results can be used by public and private decision makers to make proactive and informed decisions on the monitoring strategies to control dioxins in the pork supply chain that result in optimal resilience to a dioxin crises.
食品供应链经常受到食品安全危害进入供应链的挑战。可以使用弹性概念来研究供应链在发生食品安全威胁或冲击后在合理时间内提供安全食品的能力，将食品安全作为指标。弹性随后被定义为由于冲击而导致的食品安全绩效偏差，并同时考虑冲击的严重程度以及完全恢复或达到新平衡所需的时间。本研究开发了一个随机模拟模型，以评估荷兰猪肉供应链对饲料中二恶英污染的弹性。比较了几种监测策略之间的供应链弹性以及与污染相关的潜在成本，目的是确定二恶英监测的最佳控制点。模型结果表明，在猪肉供应链的多个控制点（特别是饲料厂和脂肪融化设施）收集和分析样本，可以在冲击后实现最高的弹性和最低的成本。该模型和这些结果可以为公共和私营决策者提供决策依据，以便在控制猪肉供应链中二恶英的监测策略方面做出积极主动和明智的决策，从而对二恶英危机实现最佳弹性。
