If you have any question that it might be an infection, carb and get the bottles to fridge temps as quickly as possible. The kinds of probiotic bacteria that commonly infect beer are similar to yeast in that they go dormant at fridge temps. As long as the beer tastes good, the infection will pretty much stop growing if the beer's cold, and they are perfectly safe to drink.
