Well now this all makes perfect sense and seems like from a chemical process point of view needs to be done. I mainly use (new) rubbermaid "BRUT" 44 gallon garabage can with wheels for mixing smaller salt batches and have used them to store ocean water (when I lived in Fla). I thought very seriously about the toxin leaching possibility but did little about CURING the Can except for rinsing out the can with copious amounts of fresh tap water. So far I have NOT had any problems from tocinf leaching (that I know about). As with any thing like this procede with caution and at your own risk. I mention my experience with this because there was question long ago asking about (possibly at another site) about using 55 gallon detergent drums from a car wash for mixing /storeing sea water. the person insisted on the fact he wanted to use them since he had access to them for free. I was pretty adiment about discouraging this idea because of leaching. Well no matter what I said I wasnt going to convince this guy that he was flirtng with disaster. After a few kill offs I thing he finally got the message. I guess the bottom line here is to make sure the container is new clean free of any smells or contaminates and rinsing cannot be done enough even between batches. Dedicating a vat just for salt batches is a very good practice, this helps to eliminate cross contamination but DOES NOT GUARANTEE THEM.
