The main criteria that consumers use during the decision‐making process when purchasing food have traditionally been a combination of prices, incomes, taste and social attitudes, with price being seen as the main determinant. However, in the past 10 years risk has become a ‘new’ criterion that can affect the consumer's decision whether or not to purchase a particular food item. The effect of the perception of risk has been observed during the numerous food scares in the last decade and in trends for the demand for foods that connote a health image. This research, carried out in Northern Ireland, looked at how consumers quantified and managed risk. The research involved 202 primary food consumers and identified the factors that were perceived to be important from both a societal and a personal perspective. Using principal component analysis techniques, societal food risks were seen as either processing or dietary, and personal food risks were seen as either extrinsic or intrinsic. Further investigation into the attributes of the personal risk using the same techniques revealed a three‐factor solution described as fear, involvement and newness. Although these factors cannot be used as predictors of the risk associated with a particular food, they help to describe and explain how the risk may be managed. The relationship between two of the factors, involvement and fear, provide a framework for understanding the way consumers manage their perception of the risk, particularly of high‐risk items. Consumer and scientific knowledge of the risk in question, and the degree of control over the risk were seen as important in the management of the risk in question. The conceptualization of the mechanism by which risks are processed and acted upon provides information regarding risk management and communication strategies that should be employed by educators, food retailers and government policy makers.
