Abstract：
UNASSIGNED: Recall announcements by the U.S. Food and Drug Administration (FDA) and Food Safety and Inspection Service (FSIS) are important communication tools. Nonetheless, previous studies revealed that the effects of recalls on consumer demand are small. Social media analytics can provide insights into public awareness of food safety-related incidents. This study included social listening data to analyze how the public, in social and online media spaces, responds to, interacts with, and references food safety recalls and/or initial announcements of foodborne illness outbreaks as reported by the Centers for Disease Control and Prevention (CDC). Analysis results suggest that mentions quantified in the social and online media searches moved closer in step with the CDC\'s initial reports of foodborne illness outbreaks than did FDA and FSIS recall announcements. Issuance of recalls may not be a popular source of food risk information in the social media space compared with reactions to the CDC\'s initial illness reports. This relative popularity reflects people more often sharing or posting about illness risk regardless of whether a recall occurs, suggesting that recall announcements by the FDA and FSIS may not induce changes in consumers\' behavior, whereas initial illness reports by the CDC may. Although recalls by the FDA and FSIS may not generate social media posts, their primary role is to take potentially unsafe food items off grocery shelves. Online media analytics provide policy makers with information to guide effective food risk communication; initial CDC reports drive immediate attention more than do FDA and FSIS recalls.

摘要：
UASSIGNED：美国食品药品监督管理局（FDA）和食品安全与检验局（FSIS）的召回公告是重要的沟通工具。尽管如此，先前的研究表明，召回对消费者需求的影响很小。社交媒体分析可以深入了解公众对食品安全相关事件的认识。这项研究包括社交倾听数据，以分析公众如何，在社交和在线媒体空间，回应,互动，以及疾病控制和预防中心（CDC）报告的食品安全召回和/或食源性疾病暴发的初步公告。分析结果表明，与FDA和FSIS召回公告相比，在社交和在线媒体搜索中量化的提及与CDC的食源性疾病暴发的初始报告更加接近。与对CDC最初疾病报告的反应相比，召回的发布可能不是社交媒体领域食品风险信息的流行来源。这种相对受欢迎程度反映了人们更经常分享或发布有关疾病风险的信息，无论是否发生召回事件，表明FDA和FSIS的召回公告可能不会引起消费者行为的变化，而CDC的最初疾病报告可能。尽管FDA和FSIS的召回可能不会产生社交媒体帖子，它们的主要作用是将潜在不安全的食品从杂货店货架上拿走。在线媒体分析为政策制定者提供信息，以指导有效的食品风险沟通;最初的CDC报告比FDA和FSIS召回更能立即引起关注。
