Why does "recycled urine" freak everyone out?

We are wired to keep safe distance from our bodies' digestive/blood
cleaning output.


There is no "unrecycled
water" on the earth.

The proportion of urine to the total amount of water (oceans, lakes)
which generates clouds and rain (natural distillation) is very low. The
porportion of urine used to make drinking water on the station is quite
high. (it is mixed with water extracted from cabin humidity so it isn't
100% urine).

There is a natural repulsion to drinking urine. One has to use logic to
overcome that repulsion and be convinced the liquid was treated and is
really water.

What worries me a bit is that the process doesn't appear to be
foolproof. The fact that the first batch of treated urine, when analysed
back on earth showed to be "good, but not good enough for drinking" is
worrysome. If the process isn't 100% foolproof, will they have to test
each batch of water produced ?
