You should be paranoid. Bleach is some nasty stuff. Check out reptilebasics.com they have several good, safe disinfectants. I currently use chlorhexadine but I want to give the F 10 Sc a shot when I need to re up.
Keep in mind that cleaning and disinfecting are two different processes. I clean my tubs and cages with dawn soap and water fairly often, but the full disinfectant treatment is maybe only every 4-6 months
