Unless it was still actively fermenting when you bottled, you should be alright. Depending on how long they've been bottled, you might want to stick the bottles in a cool, covered area out of reach of small hands or household fauna. If they've been bottled for more than 2-3 weeks, I'd say cold crash in your fridge if you're worried about bombs.
What kind of contamination are we talking about here? Sour/spoiled or musty, un-intended flavors/smells?
