| Sumario: | Observation of behaviour is superior to cognitive data, which does not equate to behaviour. Covert-observation is seldom used in food manufacturing to assess behaviour. In this case study, closed-circuit-television footage (15 h) in a business were reviewed to assess hand hygiene compliance using an electronic-checklist. Hand hygiene attempts were observed prior to entering high-risk (cake/pie)(n= 47) and high-care (sandwich/salad)(n= 153) production areas. Business hand hygiene protocol required handwashing durations ≥ 20 s. Observed durations ranged 1–71 s, <96% of attempts were <20 s. Significantly longer durations were observed when food handlers were in the presence of others (12 s) than when alone (9 s). Although <99% utilised soap, only 56–69% wetted hands first. Failure to rub all parts of hands was commonplace (<87%) and 24–35% failed to apply sanitiser after drying. Consequently, >98% of observed attempts before entering production areas did not comply with the protocol. Observed non-compliant practices may have implications for food safety in manufacturing.
