in an arid climate i'd not want to use a lot of it all the time, but right before the rainy season is likely ok.
recently the knowledge on this has changed. originally when such studies were made baterial levels were below that easily detectable, now they find that "urine is sterile" is a myth. so it does usually have some bacteria in it but that doesn't mean it is a problem when properly composted.
poo & pee together with some carbon source (sawdust, shredded leaves, etc.) is about the perfect combination and will compost nicely.
there are plenty of nutrients in feces from humans, bacteria will use it as an energy source quite easily. trace elements that did not get absorbed, etc. all often well appreciated by plant life.
though i do not believe in "design" i do think that we are here in this system and not outside of it so that what goes in and comes back out are a good part of the whole. just treat it with the respect it deserves.
if you are in an arid climate with little access to organic materials use it instead of wasting it.
