This article outlines the signs to look for in determining if kale is bad. The first sign is the color, as kale should be a dark green hue. It should also be slightly crispy and not wilted, while still being flexible. Ancient kale varieties should always have visible fibers, while modern varieties should not. Any wilting, yellowing, slimy texture, or small holes indicate decay and should be discarded. The leaves should also have no distinct odor other than fresh. If it does have a sour or vinegary smell, it should not be eaten. Finally, it is important to inspect the stems, as they should be firm, smooth, and slightly moist. Discoloration or mold on the stems indicates bad kale, and is not safe to eat. <\/p>\n
