Art. No.: R1091 / R1092
RIDA®CHECK is a rapid swab test for monitoring the efficiency of surface cleaning procedures in the production environment. The test is intended to be used as a support for hygiene monitoring as well as general protein screening in allergen management.
During production processes protein residues from raw materials or food stuffs may remain on surfaces. These should be removed during the normal cleaning process. However cleaning actions are not always successful and consequently contamination may still remain and possibly lead to the cause of future health issues.
RIDA®CHECK’s methodology is based on the detection of protein residues and is independent of ATP. During the assay the swabbed protein residues react with the indicator molecule. This interaction induces a colour change of the colorimetric substance from yellow to green. According to the intensity of the colour change (yellow → light green → green → dark green) the guideline determination of the contamination level is possible. The size of the sampling area should equal to approximately 20 cm2 (4.5 cm x 4.5 cm).
- Easy: Open package –> apply –> read.
- Fast: Results in seconds.
- Ready-to-use: No preparation of reagents, no laboratory equipment.
- Unambiguous: Green colouration of the swab = protein detected.
- Efficient: Low cost alternative to ATP measurement.
- Sensitive: Sensitive detection of protein residues (LOD = 20 µg).

RIDA®CHECK indicators are able to cross-react with bio-degradable disinfectants (mainly Chlorhexidine) which are almost entirely used for clinical or pharmaceutical purposes. In the presence of alkaline solution (pH 11 or higher) an intense colour change to dark green or blue can be observed.
|Evaluation||Colour change of colour indicator|
