Should olive oil salad dressing be refrigerated?

Olive oil salad dressing does not necessarily need to be refrigerated, especially if it contains vinegar or other acidic ingredients, which help preserve it. However, if the dressing includes fresh ingredients like garlic or herbs, refrigeration is advisable to prevent spoilage. Always check for any signs of rancidity or off smells before use, as olive oil can go bad over time. For the best flavor and quality, it's often recommended to store it in a cool, dark place.
