Training of food handlers using a virtual reality environment on handwashing is more effective than traditional training approaches in a randomized trial

Handwashing is an essential prevention step in foodservice, This randomized comparative study assessed the effectiveness of three training methods -virtual reality (VR), Glo-Germ (GT), and traditional face-to-face training (CT)- in improving handwashing practices among foodservice workers (n = 129). Training focused on the World Health Organization's 11-step handwashing process. Handwashing in the workplace was observed, in a pre- and post-test design, with microbiological swabs also taken. There was an increase in time spent on handwashing that was noticeable across all three groups (p < 0.05) with the highest in the VR group (50.16 +/- 26.04 sec.). The mean number of handwashing steps increased across all groups, and the highest increase (8.91 +/- 1.49 steps) was observed in the VR group. A statistically significant difference was observed among all groups regarding correctly performed steps, and the VR group showed the highest number of steps (p < 0.01). These findings suggest that VR-based training has value for enhancing hand hygiene practices in foodservice settings.
