Is this milk still OK or should I just dump it?

I pumped during a break today using the isis. I just left the horn attached to the bottle with the lid and stuck the whole pump in a big ziplock and then in my bag. Well, I just took the ziploc out of the bag and most of the milk had spilled out of the bottle and into the ziploc. Do you suppose this spilt milk is ok, or not? PS. the ziploc was fresh (that is, not a recycled one) if that matters.

I would use it.
