Laundering of hospital staff uniforms at home.
Few hospitals now launder staff uniforms. Staff are expected to use their own domestic machines, most of which run with 40 degrees C cycles. However, there is little information on the effectiveness of home laundering. This study demonstrates that domestic washing machines reduce viable counts of Staphylococcus aureus to below detectable levels from an inoculum of 10(8)-10(12) colony-forming units (>or=10(6)-fold reduction), even using low temperature (40 degrees C) programmes. Environmental organisms, predominantly Gram-negative flora, were introduced from the machine itself but were destroyed by tumble drying or ironing. Domestic laundering of uniforms is an acceptable alternative to hospital laundering if combined with tumble drying or ironing.
