Starter left uncovered

[tmanlua]

I had the lid blow off my starter leaving it completely uncovered for as much as 5 hours. I had planned on stepping up my starter on Tuesday and then not brewing until Saturday. I'm wondering what the chances are that my starter became infected and if it did would it be obvious by Saturday so I would know not to pitch it?

Think of an army of billions and a few invaders drop in, they usually get overwhelmed and have no chance of doing any damage.

Unless your cat peed in it while it was uncovered it will be fine to use.

If your cat DID pee in it, then you have to make an IPA and tell everyone you used Simcoe hops.
