Spinachis one of thehealthiest greens you can eat. High in vitamins and minerals, especiallyiron, it is great bothrawandcooked, and it’s fast and easy to prepare. But like all delicate leafy greens, it can break down and spoil quickly, and there is nothing more annoying than finding clumps of wet, slimy leaves in your container or bag of spinach. Read on to find out why that happens, how to prevent it in the future and what to do with a container of spinach that has some spoilage.
How to Store Spinach So It Stays Fresh
The main enemy of any leafy vegetable is moisture. Wetness creates an environment that causes the leaves to begin to break down, and they can start to rot. That slimy feel is literally decomposing plant matter. Sometimes the moisture is from water or condensation getting into the leaves; sometimes it’s from the leaves themselves, which can release liquid when bruised or crushed.
Properly packaged, undamaged spinach stored in your crisper drawer can last about a week. But it is always recommended with anyfresh produceto buy what you need as close to the day you need it as possible. This ensures the freshest quality and best taste, though we know it’s not always realistic to shop and cook this way!
Spinach that’s purchased in fresh bundles, especially at a farmers' market, is likely to be fresher than commercially packaged spinach. However, those commercial products are often already triple washed and ready to eat, which makes you that much more likely to actually consume them. Sometimes what you gain in freshness, you lose in the extra time and effort it takes to clean and prep properly.
Whether spinach in a bag or a container lasts longer comes down to how carefully you store your spinach in the refrigerator. If you tend to toss produce in the crisper without paying attention to what’s in there or rearranging the contents, then your bag of spinach may be exposed to damage. If the spinach gets smooshed or crushed, breaking the leaves and releasing their moisture, the leaves will deteriorate more quickly. Hard-shell plastic packaging protects the leaves from such damage and so they’ll last longer. If there isn’t a safe space in your fridge for bagged spinach, you may want to stick with the containers. When you’re buying the spinach, just check carefully for any signs of moisture or bruised leaves in the container or bag before tossing it in your cart.

It is very easy to tell if spinach has gone bad: it will be dark green or greenish brown, wet or slimy, and will smell a bit like algae or garbage—and taste like it, too.
It is not OK to eat slimy spinach. Any slimy spinach should be thrown away, along with any spinach it has come in contact with. You don’t want to eat decomposing plant matter (unless you’re an insect or a worm!). It’s important to remember, too, that spinach (like other leafy greens) can be be contaminated with bacteria such asE. coli. The Centers for Disease Control and Prevention cautions toprepare fresh leafy greens safelyand not to eat damaged greens.
It might be tempting to try and just rinse off or salvage slimy spinach, but the chance of giving yourself or your family gastric distress will not make any of you spinach fans. Always better safe than sorry: if your spinach has gotten slimy, discard it (offer up those slimy leaves to the worms in your compost pile). If your spinach is slimy when you open it on the same day you purchased it, you should be able to return it to the store for a refund or replacement.
Wilted spinach, however—leaves that are green and undamaged but just a little limp—can often be revived with a five-minute soak in ice water. (Here’s a guide on how to do it.) Essentially, wilted leaves are dehydrated, so soaking them replenishes their collapsing cells with the water they have lost en route to your crisper drawer.

Bottom line
The best way to prevent spinach from going off and getting slimy is to pay close attention at the point of purchase. Make sure to thoroughly examine the bag or container of spinach, looking for any signs of moisture, broken leaves, dark spots or sliminess. Discard any spinach that is slimy or has touched slimy spinach. Wilted or withered spinach can be revived in a cold-water bath. And remember to plan ahead so you can use that bag of spinach as soon as possible after bringing it home.
