Reviews the Sanitizing Efficiency of Dishwashing Machines

Cross-contamination in dishwashers

“…11 We used international standard test soils (A, 4 B, 4 C 5,6 ) and test soils with increased adherence (I, II, III). The choice of soil with increased adherence was also based on suggestions from other international standards.…”

Granule‐assisted dishwashing improves cleanliness

“…In the ANSI/NSF 3 – standard, heat load measurements are required. To fulfil this standard, more than 3600 HUE must be achieved (Poledore 1980). In early tests by Poledore (1980), Mycobacterium phlei was used both in milk and in a bacteriological medium.…”

“…To fulfil this standard, more than 3600 HUE must be achieved (Poledore 1980). In early tests by Poledore (1980), Mycobacterium phlei was used both in milk and in a bacteriological medium. From these results it was concluded that 1800 HUE was enough to fulfil a pasteurization (71.7°C, 15 s) and 3600 HUE was chosen for the dishwasher standard because M. phlei was killed by > 2900 HUE.…”
