Comparison of results of ATP bioluminescence and traditional hygiene swabbing methods for the determination of surface cleanliness at a hospital kitchen.
Adenosine triphosphate (ATP) bioluminescence and traditional microbiological swabbing culture methods were used for detection of surface hygiene on worktops, cutting boards and equipment at a hospital kitchen. A total of 280 surface samples were collected from the kitchen. The agreement between the two methods (coefficient of Kappa) was statistically significant (corrected χ2=30.886; κ=0.249; p<0.001). Consequently, the ATP monitoring method provides results rapidly with improved benefits in the control of surface contamination and application of corrective action against poor hygiene. However, it is not a substitute for culturing methods; the combination of both methods was emphasized for surface hygiene monitoring. The results indicate that, for food safety and public health, the hygienic status of the surfaces in the kitchen should be improved and food handlers should be trained well on hygiene.
