Attitudes towards using artificial intelligence to determine real-time hand hygiene compliance in the food sector

Foodhandler hand hygiene is critical to ensure food safety for consumers. Observational studies of foodhandler hand hygiene practices have been conducted in the food sector, although industry values such data the method is time-consuming/expensive. Artificial Intelligence (AI) may provide a solution, it has the potential to distinguish compliant and non-compliant hand hygiene attempts. To inform the development of such technology, this study conducted in-depth interviews (n = 12) with representatives from food manufacturing and food service businesses, to explore their perceptions of using AI technology to obtain real-time hand hygiene compliance data. A thematic analysis approach determined that both sectors discussed the importance of hand hygiene and were supportive of the proposed concept. Discussions indicated perceived benefits to include constant and longitudinal monitoring, utilizing the technology to inform training, and for assessing training effectiveness. It was discussed that real-time compliance data could be utilised to reward, recognise, and promote compliant behaviour, which in turn may enhance the food safety culture of businesses. Development of the proposed technology, informed by these findings, could single-handedly revolutionise hand hygiene compliance – safeguarding food businesses and consumers.
