Is there any danger to humans from co-habitating with a housecat that poops in a litterbox, and occasionally cleaning out that litterbox? Assuming you use litter you can find at the pet store, and have a cat without extraordinary circumstances, like rabies.
See for example http://www.naturalnews.com/041255_kitty_litter_bentonite_clay_harmful_ingredients.html:
The most common cat litters contain ingredients proven to be harmful when exposed to humans and animals. The use of sodium bentonite clay and silica gel in litters coupled with the threat of alfatoxins in grain based cat litters calls for discretion when purchasing this common household item.
If there are health dangers, what steps can be taken to avoid health risks?
