No, it just means the oil got cold! Most liquid oils begin to solidify‚ which makes them look cloudy‚ at about 50 degrees F and below. Just bring it back to room temperature and it will be fine.

The best way to store olive oilis in a dark pantry at room temperature. Light and heat accelerate spoilage; when stored properly a bottle of olive oil (even if opened) should last a couple of years. Refrigerating the oil increases its shelf life even more—but I hope you'll use up your bottle of healthful oil before that!
