Abstract
This study evaluates the influences on food handlers’ intention to conduct safe handling behaviours in food service settings in Brazil and the United Kingdom, focusing on Optimistic bias (OB). Although OB has been identified in food handlers in other studies, this is the first study evaluating the role of OB in determining behavioural intention. Three hundred participants, from the United Kingdom (n=150) and Brazil (n=150), completed a Theory of Planned Behaviour – based questionnaire, including additional questions about OB. For Brazilian food handlers, Attitude had a significant influence on Behavioural Intention followed by Subjective Norm, while Perceived Behavioural Control and OB did not significantly influence Behavioural Intention. For the United Kingdom, Perceived Behavioural Control had the largest influence, followed by Attitude, and then OB. Results suggest that cultural differences may influence predictors of behavioural intention, and that OB can contribute to predicting engagement in safe handling behaviours. Results contribute to a better understanding of the influences on food safety related behaviours.
