英文文献摘要：
Reducing the incidence of listeriosis from contaminated food has significant social health benefits, but reduction requires the use of additional or higher quality inputs at higher costs. We estimate the impact of three inputs in a food processing plant on the prevalence of L. monocytogenes contaminated finished cold smoked salmon. These three inputs were non-contamination of the raw fish fillets, non-contamination of the plant environment, and rate of glove changes on workers. We then estimate the levels of these inputs to use such that the marginal cost of these inputs become equal to the increased social health benefit of reduction in human listeriosis. Since the costs of these inputs are borne by the food processing plant, which may not be able to secure a higher product price because of asymmetric information, we show how social sub-optimal use of these inputs may result.
减少由受污染食品引起的李斯特菌病的发病率具有显著的社会健康效益，但减少需要以更高的成本使用更多或更高质量的投入。我们估计了食品加工厂的三种输入对受L.单核增生基因污染的成品冷熏鲑鱼流行率的影响。这三种投入品分别是生鱼片的无污染、工厂环境的无污染以及工人的手套更换率。然后我们估计这些投入的使用水平，使这些投入的边际成本等于减少人类李斯特菌病所增加的社会健康效益。由于这些投入的成本是由食品加工厂承担的，而由于信息不对称，食品加工厂可能无法保证较高的产品价格，因此我们展示了这些投入的社会次优使用可能导致的结果。
