ABSTRACT
This study aimed to determine the underlying factors influencing street food vendors' implementation of food safety behaviours related to food handling. A questionnaire based on the Theory of Planned Behaviour was applied to 303 street food vendors in Southern Brazil. Open-ended questions identified that consequences related to consumers were important factors influencing street food vendors' food safety behaviour. Also, water supply and lack of water were identified, respectively, as possible facilitators and barriers to carry out food safety behaviours such as handwashing and cleaning the shelf used to prepare food. Optimistic bias was identified and the majority of street food vendors gave positive results related to perceived behavioural control, subjective norm, attitude and behavioural intention. Improvements are needed in government regulation, infrastructure and food safety training for this sector, with measures that reflect and are adapted to the street food environment.
Este estudio tuvo como objetivo determinar los factores subyacentes que influyen en la implementación del comportamiento de seguridad de los alimentos en la manipulación de alimentos por vendedores ambulantes de alimentos. Se aplicó un cuestionario basado en la Teoría del Comportamiento Planificado a 303 vendedores ambulantes de alimentos en el sur de Brasil. Las preguntas abiertas identificaron que las consecuencias relacionadas con los consumidores eran factores importantes que influían en el comportamiento de seguridad de los alimentos por parte de los vendedores ambulantes de alimentos. También se identificaron el suministro de agua y la falta de agua, respectivamente, como posibles facilitadores y barreras para realizar comportamientos de seguridad de los alimentos como lavarse las manos y limpiar la mesa de trabajo que utilizan para preparar los alimentos. Se identificó sesgo optimista y la mayoría de los vendedores ambulantes de alimentos dieron resultados positivos relacionados con el control conductual percibido, la norma subjetiva, la actitud y la intención de comportamiento. Se necesitan mejoras en la regulación gubernamental, la infraestructura y la capacitación en seguridad de los alimentos para el sector, con medidas que reflejen y se adapten al entorno de la comida callejera.
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.
