28 pages, This study investigates how the emotional tone of food safety risk communication messages predicts message virality on social media. Through a professional Internet content tracking service, we gathered news articles written about the 2018 romaine lettuce recall published online between October 30th and November 29th, 2018. We retrieved the number of times each article was shared on Twitter and Pinterest, and the number of engagements (shares, likes, and comments) for each article on Facebook and Reddit. We randomly selected 10% of the articles (n = 377) and characterized the emotional tone of each article using machine learning, including emotional characteristics such as discrete emotions, emotional valence, arousal, and dominance. Conveying negative valence, low arousal, and high dominance, as well as anger and sadness emotions were associated with greater virality of articles on social media. Implications of these findings for risk communication in the age of social media are discussed.

James F. Evans Collection, This article describes the development and preliminary evaluation of model materials designed as one step in helping consumers understand how scientists assess food risks, how that information is used in food safety policy decisions, and what individuals can do to protect themselves from residual risks. Focus groups provided feedback on draft materials, and experts reviewed the simplified descriptions of specific food risks to assure consistency with current scientific knowledge. We used pilot tests to examine (1) whether initial factual questions would prompt more learning, and (2) the relative effectiveness of two formats: a paper version similar to typical government pamphlets and an interactive computer version. People learned about food safety from either version. There was little evidence that the "prompting" questions led to more learning, nor did subjects learn more from the computer version. Results suggest that the materials made respondents more comfortable about their own ability to choose and prepare safe food and increased their confidence in actions taken by government and industry.
