Purpose: This study was conducted to compare the sanitary inspection results and the ATP measurements on foodservice equipment.
Methods: Dietitians of the Center for Children"s Foodservice Management (CCFSM) visited 192 foodservices to conduct a sanitary inspection and ATP assay at the same time.
Results: The ATP were gained for knives (79.53±296.20 RLU/cm2), cutting boards (19.70±65.17 RLU/cm2), food distribution trays (51.47±390.95 RLU/cm2). When comparing the sanitary inspection results for knives with the ATP sanitation standard (below 3 RLU/cm2 for food contact surface is a pass), knives from 104 foodservices that performed ‘Control/sterilize knives and cutting board sanitarily’ showed ATP results of a 40.4% pass which was less than the 59.6% fail. In addition, 145 foodservices that performed ‘Use separate knives/cutting boards for fish/meat/ vegetables’ showed a 32.4% pass and 67.6% fail ATP results on knives. This suggests that there is a gap in between the naked eye sanitary inspection results and the ATP measurements. The results of cutting boards and distribution trays were also similar.
Conclusion: An ATP hygiene monitoring system needs to be conducted simultaneously with a naked eye sanitary inspection to insure that the microbial hazards are eliminated or reduced.
