It can not be rust.
IMO.By looking at the crystals it seems to be that they were cross contaminated with something.
It looks as though one or some of them my have ruptured and spilled out onto the screen.
Thus discoloring it.

I agree, I deal with this alot where I work, the product/cleaning acids/glycol/ will turn 316 stainless a rust color, which is actually called rouge. The stainless then needs to be derouged using other chemicals.
There's no doubt that a bead or 2 broke and caused the bad smell and taste, and the rust/rouge of the stainless screen.
