The risk in urine is probably best shown IMHO by the federal regulation of wild and scenic rivers. Where while rafting one must capture feces in a sealed can (the gruver) to be disposed after the trip. Urine however is to be discharged into moving water.

There are few nearly sterile conditions associated with living tissue. Living and sterile are incompatible terms, but urine comes close. Spinal and cerebral fluids are usually free of microbes, but "steer" away from cattle brains. What bacteria enters the lumen of the stomach is usually short-lived due to the low pH.

It's interesting to note that dicot fruits such as tomatoes can be safe to eat after washing the exterior when that are grown from the sludge of sewage treatment plants because of the protective barrier of the casparian strip in their vascular system, but I would not recommend the potatoes or carrots.

Sterility is rare in nature, but there are some safe practices.
