How to Tell If Spinach Is Bad
Quick answer
Bad spinach turns slimy, dark green to black, and wet, with a sour, sulfur-like smell. A few wilted or slightly yellow leaves can be picked out; if the bag is wet and slick, toss it.
Signs Spinach has gone bad
- Slimy, slick texture. Rub a leaf between your fingers. If it feels slippery or leaves a film, the spinach is breaking down. Toss it.
- Dark, wet, mushy leaves. Leaves that go deep green-black and collapse into a wet mess are rotten. Pick out a few, but if much of the bag looks like this, discard all of it.
- Sour or sulfur-like smell. Spinach smells mild and slightly earthy. A sharp, sour, or eggy odor means it has spoiled.
- Pooled water in the bag. Liquid sitting at the bottom speeds decay. If the leaves are also slimy, throw the bag out.
- Mold or fuzzy spots. White or gray fuzz on leaves or stems means mold, and with such delicate greens, discard the whole batch.
- Yellowing that spreads across most leaves. A few yellow leaves are fine to remove. When most turn yellow and limp, the batch is past its prime and may be starting to rot.
Looks weird, but it's fine
- Slightly wilted leaves. Spinach wilts quickly. If it’s not slimy or smelly, wilted leaves are great for cooking.
- A few yellowed or dry leaves. Pick them out and use the rest.
- Dirt or small tears. Loose-leaf and bunch spinach often has grit. Wash thoroughly, even if a bag says pre-washed, for extra peace of mind.
How long does Spinach last?
| Where | How long | Note |
|---|---|---|
| Fridge | 3–7 days | fresh, in original bag or container |
| Fridge | 3–5 days | cooked |
| Freezer | 10–12 months | blanched, squeezed dry |
How to store it
- Keep spinach cold in the main part of the fridge, not the door, and tuck a dry paper towel into the container to absorb moisture.
- Don’t wash it until you’re ready to use it. Extra moisture is the main cause of slimy leaves.
- Freeze extra spinach, blanched and squeezed dry, for soups, smoothies, and sauces.
Use it up before it turns
Frequently asked questions
Can you eat slightly wilted spinach?
Yes, if it’s not slimy and smells fine. Cook it in soups, pasta, or eggs where texture doesn’t matter.
Is spinach with dark spots safe?
A few dark spots on a leaf can be cut away. If the leaves are wet, dark, and slimy, or smell off, throw the batch out.
How long does bagged spinach last after opening?
Plan on 3–5 days after opening if it’s kept cold and dry. Check for slime and sour smell before using, and trust those over the date on the bag.
