How long can you keep herring in the refrigerator?

Herring can typically be kept in the refrigerator for about 1 to 2 days if it's fresh. If it's pickled or smoked, it can last longer, usually up to a week or more, depending on the specific preparation and storage conditions. Always check for signs of spoilage, such as off odors or changes in texture, before consuming. For longer storage, consider freezing it.
