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.
BACKGROUND: Even with optimal treatment, injuries from pumpkin carving accidents may leave people with compromised hand function. Pumpkin carving tools may reduce the incidence and/or magnitude of these injuries. However, evidence that they are safer is required before these knives can be recommended. METHODS: Two pumpkin carving knives were compared to a serrated and a plain kitchen knife. The forces required to cut and pierce a pumpkin were determined and then applied by a servo-hydraulic machine to each knife placed against cadaver hands in a manner designed to either lacerate Zone 2 of the finger (six tests for each knife) or to puncture the hand. Inspection and dissection determined the extent of injury. RESULTS: The pumpkin knives produced some injuries, however, they were fewer and less severe than those caused by the kitchen knives. CONCLUSIONS: Tools designed specifically for pumpkin carving may indeed be safer. Use of these products, and increased overall awareness of the risks of pumpkin carving in general, which clinicians could help promote, might reduce the frequency and severity of pumpkin carving injuries.
