A web-based survey was conducted with Japanese consumers (N=4,363) from Oct.-Nov. 2011 to investigate perceptions about health risks from beef that was potentially affected by contamination from radioactivity due to the nuclear power plant accident or the E.coli O111 outbreak in 2011. Enteroheamorrhaghic E. coli was regarded as the highest risk whereas radioactivity ranked 6th rank out of seven beef-related hazards. While the perceived risk of radioactivity in beef was comparatively low, respondents revealed lower willingness to pay for the food produced in the affected area. For example, even for beef without radioactivity detected, 40.3% of consumers had a lower willingness to pay. When radioactivity was detected in beef, but below acceptable limits, 70.1% of consumers had a lower willingness to pay. Knowledge level on radioactivity in beef had limited impact on price evaluation by consumers, but attitudes regarding risk management significantly affected the price evaluation of food from the affected area.
