The main issue here is that you asked about removing items from the brine to use for another time. This is a problem, as they have been cross contaminated, and it would give the bacteria a chance to multiply.
Even if you were to kill those bacteria, you don’t know what byproducts they created, so you don’t know what’s required to denature them.
If you really wanted to try to make use of them a second time, I would recommend immediately boiling them to make a stock, and then straining and refrigerating the stock (discarding the solid matter, which should have given up its flavor).
