Abstract

Purpose Food handlers working in food service establishments need to perform appropriate and consistent food safety practices to ensure that the prepared food is safe for consumers to eat, as a failure to do so may lead to foodborne illness. It is important to have an in-depth understanding of food handler food safety behaviour in the food service sector to design targeted educational interventions and approaches to safeguard consumers. The purpose of this review is to provide insight to the existing body of research regarding food handler food safety in the food service sector, and to identify future research needs in terms of methods and measures. Methods This study is a review of published food safety research studies (n = 118) focusing on food handlers in the food service sector conducted between 2001 and 2021. Data were collated regarding the methods used and the measures assessed in published studies to identify the gaps in current knowledge related to food safety in food service. Findings The majority of studies were conducted in the United States (29%), Brazil (17%) and United Kingdom (7%). A large proportion were carried out in restaurants (70%). Less than a third of studies (28%) relied on a mixed method approach for data collection; and only 12% of studies assessed a combination of cognitive and behavioural measures. Observation was used in only 29% of studies. A lack of observational data detailing food safety practices such as handwashing, temperature control, separation and cleaning was determined. Significance Such findings indicate a greater need for mixed method approach in future food safety research. It is recommended that the understanding of food handler food safety performance is best obtained through a combined assessment of cognitive and behavioural measures with subsequent triangulation of findings to reduce bias and to obtain reliable results.
