> However, I have always been told not to keep rice in the rice cooker for days at a time, for health reasons. If it's warm, I'd imagine it's an even better environment for bacterial/spore growth. IIRC, the reason Zojirushi gives for not keeping rice warm for too long is that it will get yellow and hard. I don't think they mentioned food safety concerns. Mine does have a small vent hole, so I guess the moisture must escape eventually.
