Energy Efficient and Microbially Nasty

            A German children’s hospital tracked down the source of a outbreak of Klebsiella in their neonatal unit recently leading to trashing an energy efficient washing machine.  Thankfully the infants were only colonized and none were infected by the potentially harmful bacteria.  Normally any hospital laundry would be sanitized by special machines, but this wash was being used to wash the little boots and mittens which kept the infants warm. 

            It appears that energy efficient washers use lower temperatures to save on your electric bill but this may allow more bacteria to survive the cleaning process. 

            I am not saying you should trash your energy efficient front loader, but you do want to keep it clean so you don’t end up with your own contaminated laundry.  Living a healthier more abundant life means watching out for all sources of bad microbes.
