Food production processes have a number of critical control points that influence the quality assurance in production processes. In Ghana, foodborne illnesses reported in hospitals is about 420,000 per year, with an annual death rate estimated at 65,000 costing $ 69 million to the Ghanaian economy. This research therefore assessed the knowledge level of food safety and consumer perception for irradiated food in the greater Accra region. The combination of data obtained from workshops and interviews gave overview of food safety and consumer perception to irradiated food products. Data were analysed with SPSS and to map the mental models of those involved in the workshop, a Vensim software program was used. The survey report showed that even though respondents were told of the sterility assurance level of food irradiation, about 80 percent of them rejected irradiation processing until educated. All respondents have experiences food borne illness before. Majority of the interviewed respondents (85%) express some degree of concern over the safety of the food supply and some are willing to pay 10% premium for irradiated foods. The mental model revealed that demand for safer convenient food emphasised the need for refining food policy and increasing critical control point’s inspection by the standard authorities. This will lead to Good Manufacturing Practices (GMPs) and safer foods than it would otherwise be and hence promote public health. It is suggested that there is a need to refine food safety policy to include irradiation processing, which can respond to both domestic and global challenges.
