HIGH LIPASE MILK--need advice

So I go back to work in two weeks so I have been pumping my stash for about a month--I have roughly 100oz frozen. I decided today that I was going to give my LO a milk bath tonight so I took out the very first bag I froze. Unfortunately, somehow while it was thawing it came open and leaked all over the counter. I could smell metallic so I tried to taste the drops left in the bag...metallic!!! So that brings me to my list of questions...
Does that mean all of my milk will be like that? Should I start scalding from now on? 
Is the rest of my precious gold a wash? 
Please advise..I have been very anxious about returning to work, particularly over making sure she will eat while I'm gone.
