ATP ... when clean to sight and touch is not enough.
Every high-touch surface in a healthcare facility is different but important to understand in its potential role in HAI outbreaks. Each carries an unknown risk factor for contaminating the hands, bare or gloved. These hands in turn can contaminate other surfaces, hands and even enter the food served to these immune-compromized residents and patients. Grouping these touches, with the HACCP principle in mind, is a good first step - prioritizing those touches that must trigger a hand cleaning event and a specific regimen.
