ok to feed LO milk from a new pump that has not been sterilized?

kiwasun

I just bought a brand new Medela breastpump and was so excited to use it that I skipped the sterilizing step. I just rinsed all the parts with warm water. Now I'm concerned--Is it ok to feed my 3 month old the milk that I expressed? The actual bottle it went into WAS sterilized, just not the nipple shield and pump parts.

What do you think?? Use the pumped milk or dump it out?
