本研究結合健康與傳播理論觀點，利用傳播調查資料庫 2016 年所蒐集的面訪資料探索食品安全資訊接收管道、食品安 全風險認知與感知、食品安全資訊分享管道，與食品安全預防 措施間的結構關係。研究發現，由電視接收食安資訊增加食安 風險的易感性認知與嚴重性感知，但由網路接收食安資訊與風 險感知、認知無顯著直接關係；食安風險嚴重性感知會透過線 下食安資訊分享，提高採取預防措施的數量。此外，由電視、 網路接收食安資訊，分別增加線下、線上食安資訊分享，進而 提高個人採取食安預防措施數量。這些結果顯示，由不同管道 獲得食安資訊可能造成食安風險應對差異，而食安資訊分享是 轉化食安資訊接收、食安風險認知與感知為食安風險預防行為 的重要機制。

Drawing on both health and communication theoretical models, this study explores the relationships among food-safety information reception, perceived susceptibility and severity, information sharing, and preventive actions. Results show that receiving food-safety information from television increases perceived susceptibility and severity, whereas receiving relevant information from the Internet does not significantly relate to these outcomes. The increased perception of susceptibility and severity in turn raises preventive actions via information sharing online and offline, respectively. The results further illustrate that receiving food-safety information from television and the Internet increases the sharing of relevant information offline and online, respectively, which in turn enhances the number of preventive actions people take. Overall, these findings indicate that diverse sources of food-safety information shape reactions toward food-safety risks differently, and that information sharing is an important mechanism through which information reception, perceived susceptibility, and severity transform into preventive actions.
