ABSTRACT

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.

摘要

对行为的观察优于认知数据，认知数据并不等同于行为。食品制造中很少使用隐蔽观察来评估行为。在本案例研究中，审查了一家企业的闭路电视录像（15 小时），以使用电子检查表评估手部卫生依从性。在进入高风险（蛋糕/馅饼）（n = 47）和高护理（三明治/沙拉）（n= 153) 生产区域。商业手卫生协议要求洗手时间≥ 20 秒。观察到的持续时间为 1-71 秒，<96% 的尝试<20 秒。当食品处理人员在其他人在场时（12 秒），观察到的持续时间明显长于单独时（9 秒）。虽然 <99% 使用肥皂，但只有 56-69% 先弄湿手。没有擦手的所有部位是司空见惯的（<87%），24-35% 的人在干燥后没有使用消毒剂。因此，在进入生产区域之前观察到的超过 98% 的尝试不符合协议。观察到的不合规做法可能会对制造过程中的食品安全产生影响。
