I think a half hour is absolutely fine for it to sit out. According to kellymom.com, it can remain at room temperature for 6-8 hours (!) although I'd personally not drink a cup of milk if it had been sitting out for that long.

Here is a link to a page on kellymom which talks about reusing/saving expressed breastmilk (and includes that 6-8 hour mention) which may be of help to you:

Once baby has drunk from the bottle, I think the longest 'they' say to keep it is 2 hours. Bacteria get transfered from baby's mouth to the milk. Breastmilk that has not been drunk is a totally different matter and is good for hours like the PP mentioned.
