Dishwashers are used in central hospital kitchens and ward kitchens to provide clean crockery. Soil recipes based on international standards were tested in order to evaluate the performance of a general dishwasher. In normal use of dishwashers, adherent soils are left on the crockery before cleaning. Different adherent soils, both with and without bacterial contamination, were used to show the effectiveness of the dishwasher to remove this type of soil. It was shown that contamination will occur from the dishwater to crockery with adherent soil. These results demonstrate the importance of cleaning soiled surfaces of crockery mechanically in the dishwashing process. Otherwise cross-contamination, and thereby the spread of infections, may occur.
中央医院厨房和病房厨房使用洗碗机来提供清洁的餐具。基于国际标准的污垢配方经过测试，以评估普通洗碗机的性能。在洗碗机的正常使用中，清洁前餐具上会残留附着性污垢。使用了不同的附着性污垢，包括有细菌污染和无细菌污染的，以展示洗碗机去除此类污垢的效果。结果表明，有附着性污垢的餐具会受到洗碗水的污染。这些结果证明了在洗碗过程中对餐具污染表面进行机械清洁的重要性。否则可能会发生交叉污染，进而导致感染传播。
