Sales of irradiated foods clearly indicate that North Americans consum
ers appreciate the value of irradiated foods. All irradiated foods off
ered for sale have sold well. The results of North American consumer a
ttitude surveys can be used to predict acceptance of quality irradiate
d foods, especially when improved food safety is the perceived benefit
. Consumers perceive the most benefit when irradiation is used to impr
ove food safety or to reduce the chemicals used on foods. Information
about irradiation seems to increase consumer willingness to buy. Consu
mer activists continue to attempt to prevent the sale of labelled irra
diated foods, but they have not been successful.
