Yes, raisins can indeed go bad. Whilst it is rare to come across a moldy package of raisins, since the shelf life is generally pretty long, it can happen, especially when the raisins have been open for some time, and kept in a hot area. Just keep an eye out for signs that they are bad and use your best judgment.

How do you know when raisins have gone bad?
