Can Mushrooms Get Moldy? How To Tell If They Are Safe To Eat

Have you ever looked at mushrooms in the grocery store and wondered, ‘Can mushrooms get moldy?’

Since mushrooms are a type of fungi, and so is mold, it might seem a bit confusing. But the truth is, mushrooms can indeed grow mold, just like any other food.

So let’s explore this mushroom mystery together!

Why Do Mushrooms Get Moldy?

Moldy Mushrooms

Mold is a bit like an invisible, tiny explorer traveling through the air. These microscopic adventurers, known as mold spores, are on a quest to find the perfect spot to settle down and grow. They’re not picky and will make themselves at home anywhere that’s moist enough to support them. This includes our own homes and the great outdoors.

To prevent these spores from turning our food into their new residence, we often use airtight containers. These containers act like a shield, making it tough for mold spores to invade and spoil our delicious edibles, such as mushrooms.

When mushrooms age, they can sometimes give off water, turning them into an ideal environment for mold. This moisture, combined with nutrients in the mushrooms, provides everything mold needs to thrive.

That’s why when we stumble upon mushrooms that have been forgotten in the fridge or left on the counter for too long, we often notice they have become moldy. To keep mushrooms fresh and free from mold, it’s best to store them in a cool, dry place and use them while they’re still fresh.

How to Spot Mushrooms That Have Gone Bad

It is important to learn how to tell if your mushrooms have gone bad. Mushrooms tend to get mold if left outside in damp environments for long periods.

Check the Mushrooms Smell and Texture 

Fresh mushrooms have a natural, slightly earthy smell. If your mushrooms give off an odd or unpleasant odor, it’s likely they’re past their prime. A fresh mushroom should also be relatively dry and firm. When they start to go bad, they can become slimy or tacky to the touch. This sliminess is a clear indicator that mold might be present, and it’s time to toss them out.

Look for Visible Signs of White Fuzz on Mushrooms

Mold on mushrooms can appear in various colors, like white, gray, blue, or green. It often looks like a fuzzy or furry coating. According to the United States Department of Agriculture (U.S.D.A), any visible mold is a sign that the mushrooms are no longer safe to eat. Even if only one mushroom in the pack looks affected, the others could be contaminated too, so it’s best to get rid of the entire batch.

When in Doubt, Throw Them Out 

If you’re unsure whether your mushrooms have grown mold, it’s always safer to err on the side of caution. Eating bad mushrooms can lead to allergic reactions or food poisoning in some people. It’s important to discard any mushrooms in the bunch you suspect have gone bad. Check the rest of the batch for any discoloration or other signs.

Keeping Mushrooms Fresh and Mold-Free

Wondering how to prevent those pesky fungi from ruining your shrooms? Proper storage is your best friend here. Typically, mushrooms can stay good for up to ten days when stored correctly. However, once you slice them, their shelf life decreases. Sliced mushrooms usually stay good for about seven days.

Here’s a handy tip: skip the rinse before you store mushrooms. Why? Because mold thrives in damp environments! If you feel your mushrooms need cleaning, hold off until you’re just about to use them. Another trick is to store them in a brown paper bag inside your refrigerator. This bag acts like a sponge, absorbing excess moisture that mushrooms release as they age.

When placing mushrooms in the fridge, treat them with care. Avoid piling heavy items on top of them, and be careful not to bruise their delicate surfaces. Bruises can accelerate mold growth. If you don’t plan on using your mushrooms in the near future, consider cooking them first, then freezing them for later use. Alternatively, you have the option to dry them out. Drying your mushrooms preserves them for an extended period.

Usage of proper storage techniques is the best way to ensure 

What We’ve Learned About Mushrooms and Mold

Both mushrooms and mold are types of fungi, but they’re not the same.

White fuzz on mushrooms is a sign of mold. If they are slimy to the touch or smell unpleasant, they may have gone bad. It is important to show caution and discard moldy mushrooms.

To keep our mushrooms tasty and fresh, we need to keep them dry. Mushrooms last longer if you store them properly. We can’t stop these fungi from releasing water as they get older, but we can use smart storage methods to help them last longer without getting moldy.
