The impact of food safety events on the value of food-related firms: An event study approach.

Food safety events threaten not only consumers' health, but also the value of associated firms. While previous studies examined the impact of food safety events on consumer demand for products, little attention has been paid to the impact on the market value of firms. Using the event study method (ESM), this study investigated abnormal returns (ARs) and cumulative abnormal returns (CARs) of firms associated with 40 food safety events over the past 25 years in the U.S. The results of this study demonstrated the magnitude and duration of the impact of food safety events on firm value. Moreover, firm-specific factors (past history and firm size) and situational factor (media attention) were found to influence the magnitude of the impact. This study contributes to the hospitality literature by extending the knowledge of the impact of food safety events and its practical implications for effective crisis management strategies for food-related firms.
