Same, used brine water is not something I would warm up. Its got funk in it you dont want anywhere else - IMO.I would toss it and start new myself . Not saying it isn't / wouldn't be safe , but that stuff gets everywhere . I try to keep it contained to one area , plus I would think it needs to get to a boil to take any risk out of the equation .
Agreed, I would toss it, I almost always keep a water pan under my proteins in my egg and use as a heat shield as well as collect the juices. I typically though some carrots, celery onions, garlic, ect and some stock and whatever might enhance the flavors, plus it gives me something to add back if needed in the end, but I always boil it after, and would never use the brine liquid... just in caseI would toss it and start new myself .
