History
• Visual inspection is inadequate• Plate counts
– Detects only microbes– Requires skilled analysts in labs– Expensive– Slow – Tells nothing about the removal of
dirt and organic matter

Rapid Alternative Method ATP Bioluminescence
• ATP = Adenosine Triphosphate– Universal energy carrier – Present in all living things and organic matter (dirt and microbes)
• Bioluminescence– Natural reaction producing light – Specific enzyme reacts only with ATP– Results in seconds– Light is measured by an instrument and gives a numerical output
• Simple Test Method – ATP collected by a swab sample reacts with a test reagent – Light detected by the instrument– High ATP = High contamination– Low ATP = Low contamination

Standards & Targets• No universal Pass / Fail limits
– Surfaces vary in form, function, contamination risk and cleaning duty
– Compare before and after cleaning• General guidance for SystemSURE Plus
– Pass < 20 RLU – Caution 21 - 49– Fail > 50
• Higher standards e.g. Pass < 10 and Fail > 30• Trend analysis and continuous review to improve
standards that are achievable.

Benefits of Rapid ATP test• Verify cleaning has been achieved
– Direct objective test for removal of organic matter– Better than visual inspection – Better than traditional microbiological methods
• Identify high risk vulnerable areas• Provide rapid result (15 sec) for
– on-the-spot information– Immediate corrective action e.g. re-clean
• Evidence of due diligence • Provides objective data
– trend analysis and continuous improvement
