How can I tell if fresh cranberries have gone bad?
Fresh cranberries can spoil quickly if they are not stored properly. To check if fresh cranberries have gone bad, look for signs of mold, softness, or an off smell. Mold can appear as a white, green, or black fuzzy growth on the surface of the berries. Soft or mushy berries are also a sign of spoilage, as fresh cranberries should be firm and tart. An off smell, such as a sour or ammonia-like odor, can also indicate that the berries have gone bad.
If you notice any of these signs, it is best to discard the berries immediately to avoid foodborne illness. Even if only a few berries are affected, it is recommended to discard the entire batch, as the spoilage can spread quickly to the rest of the berries. When checking for spoilage, it is essential to inspect the berries carefully, as mold or softness can be hidden among the berries.
