The Impact of Risk Communication on the Acceptance of Irradiated Food

Lulu Rodriguez

Iowa State University, Ames, lulurod@iastate.edu

This study uses a quasi-experimental design to assess the impact of pro- and anti-food irradiation messages on consumer opinions. The data came from a panel study of 223 adults in Minneapolis, Minnesota, who completed three successive questionnaires. One group received a packet of information materials; another did not. Packet recipients perceived irradiation to be less safe and held less favorable opinions about the protagonists in the irradiation debate. Opinions changed over three months, although the changes were not statistically significant. Those who did not receive the packet showed significantly more favorable opinions of food irradiation opponents.

Key Words: risk communication • food irradiation • food safety
