Hot water - boiling water - a run through the dishwasher - all these will clean the mould away. If you're really concerned there's a product called Mliton used for sterilising baby feeding bottles - kills everything and has no aftertaste - home brew sterilising tablets will also do the same thing.
If it was me I'd just make a pot of coffee and see how I was the next day - you'll very probably live.
