Chemical test for the evaluation of the cleanliness of surfaces
The utilisation possibilities of the surface cleanliness test range from hospitals to food manufacturing, for example, which has high requirements for hygiene. Picture: Juha Rahkonen
Orion Clean Card PRO, a chemical test for the assessment and monitoring of surface hygiene, is the result of collaboration between Orion Diagnostica and VTT Technical Research Centre of Finland. The test card is manufactured by printing. The surface to be monitored is simply moistened and wiped with the test card. The result is available immediately, as a colour change indicates if protein impurities remain on the surface.
EU food safety regulations and the Finnish Food Act require food processing organisations to carry out self-monitoring and surface hygiene verification. Hospitals are another area where hygiene standards undergo constant development. In Finland alone, some 50,000 infections are thought to be spread in hospitals every year.
