Mastitis and storing milk?

vszapp

I think I have mastitis. I have sore area on one breast and I felt awful yesterday afternoon (spiked a small fever too). I started treating it aggressively, and it is at least not getting worse. I pump during the day while I'm working, so it just dawned on me that all of the milk from yesterday probably has loads of bacteria in it. Is it safe to store and feed to her, or should I dump it? I know it's OK to BF her while I have this, but I've never heard what to do with the expressed milk.
