Yes --- if they mix it right or change it when they should --- but how carefully are things like that always checked? I've seen some filthy hospital floors --- blood from a previous patient on the floor. I was shocked at a bathroom near an Emergency Room with used dirty toilet paper thrown on the floor piled up in each stall. It was obviously used by some pretty disgusting people --- more than one --- and hadn't been cleaned for hours.
Agreed. I've never seen that, though, at our small hospitals.
