Cost implications of improving food safety in the Dutch dairy chain
研究用整数线性规划模型分析荷兰乳制品链中改善食品安全的控制措施，发现65%的最大食品安全改善可通过每吨牛奶4.27欧元的较低额外成本实现，而更高安全水平需农场环节更多投入，成本升至44.37欧元。
This paper examines control measures for improving food safety in the dairy chain, using an integer linear programming model. The chain includes feed (compound feed production and delivery), farm (dairy farm) and dairy processing (transport and processing of raw milk, delivery of pasteurised milk) blocks. Results show that 65 per cent of the maximum possible food safety improvement can be achieved at relatively low extra cost per ton of milk (€4.27), fairly evenly distributed across the blocks. Higher safety levels can be attained by increasing the farm block's contribution, but at much higher extra cost (€44.37 for the maximum attainable).
