In September 2018, a former strawberry‐picking supervisor for a strawberry farm in New South Wales was arrested for inserting sewing needles in hundreds of punnets of fresh strawberries sold in retail stores across several Australian states. This paper analyses the 2018 Australian strawberry needle scare as a case study on the market impacts of agro‐terrorism events. We develop a novel four‐step procedure to estimate the effects of the strawberry needle contamination on wholesale fresh strawberry prices. Our results indicate a drop in wholesale fresh strawberries prices of about 20% while the needle crisis was ongoing. However, public and private supply restrictions caused wholesale prices to rise by up to 94% relative to expected dynamics over several weeks in the immediate wake of the incident.

缝制恐怖：草莓危机的价格动态

2018年9月，一名前新南威尔士州草莓农场采摘草莓的主管因在澳大利亚多个州的零售商店出售的数百个新鲜草莓strawberries中插入缝衣针而被捕。本文以农业恐怖主义事件对市场的影响为案例，分析了2018年澳大利亚草莓针刺恐慌事件。我们开发了一种新颖的四步程序来估算草莓针头污染对新鲜草莓批发价的影响。我们的结果表明，在针刺危机持续期间，新鲜草莓的批发价下降了约20％。然而，在事件发生后的几周内，公共和私人供应限制导致批发价格相对于预期的动态上涨了94％。
