| Abstract |
We investigated the relationship between the temperature of reused towels after microwave heating and change of Bacillus cereus concentration after heating by heat block. The average temperature at the center of reused towels showed 98.8°C after microwave heating at 700 W for 2 min. B. cereus of clinical isolated was detected after 92.0°C for 65 min and 85.0°C for 240 min by heating of heat block. These findings suggest that heating at a temperature of 98.8°C for 10 min is sufficient and that B. cereus concentrations might be reduced by 90% by microwave heating at 700 W for 12 min. Therefore, because it is difficult to heat each one towel for 12 min by microwave at medical institutions, it is unlikely the merely extending microwave heating time would have a substantial effect on B. cereus concentrations in reused towels. |
