Are collard greens with brownish spots on back of leaves safe to eat?

Collard greens with brownish spots on the back of the leaves may not be safe to eat, as these spots could indicate the presence of pests, disease, or decay. It's important to inspect the greens carefully; if the spots are extensive or the leaves feel slimy or have an off smell, it's best to discard them. However, if the spots are minimal and the leaves are otherwise fresh, you can wash them thoroughly and remove the affected areas before cooking. Always prioritize food safety when assessing produce.
