Consumer Perceptions Of Food Safety And Preferences For Food Safety Interventions, Kofi Britwum

A hypothetical survey which includes six information treatments was developed, and targeted a representative, random sample of U.S consumers. Participants were exposed to general information about E. coli and the two food safety technologies, a gain-framed message, a loss-framed message, a media …
