How To Know If Summer Squash Is Bad

Summer squash is bad when it develops soft spots, mold, or a slimy texture.
 
If you’ve been wondering how to know if summer squash is bad, the answer usually shows up in its appearance, feel, and smell.
 
Summer squash doesn’t last forever, even when stored properly in the fridge.
 
In this post, we’ll walk through the signs that summer squash has gone bad, how to store it so it lasts longer, and what to do if you’re not quite sure whether it’s still good.
 
Let’s get into it.
 

How to Know If Summer Squash Is Bad

Knowing if summer squash is bad comes down to a few clear signals.
 
Summer squash is bad when it shows any of the following signs.
 

1. Soft or Mushy Spots

Fresh summer squash should feel firm when you press it.
 
If you notice soft spots or the skin gives way easily under your thumb, that summer squash is likely going bad.
 
Mushy patches mean the cells inside have started to break down, which happens as squash ages or sits too long in warm conditions.
 
Once summer squash turns mushy, there’s no bringing it back.
 

2. Wrinkled or Shriveled Skin

Another way to know if summer squash is bad is by looking at the skin.
 
Fresh summer squash has smooth, glossy skin that feels taut.
 
When summer squash starts to go bad, the skin wrinkles and shrivels as it loses moisture.
 
A little shrinkage doesn’t always mean it’s unsafe, but heavily wrinkled summer squash will taste dry and bland.
 

3. Mold Growth

Mold is one of the clearest signs that summer squash is bad.
 
You might see white, gray, or green fuzzy patches on the surface, especially near the ends.
 
If summer squash has mold, toss the whole thing out.
 
Cutting off the moldy part isn’t safe because mold roots can spread deeper than what you see.
 

4. Slimy Texture

If summer squash feels slimy or sticky, that’s a red flag.
 
Sliminess usually means bacteria have taken over, and that summer squash is bad news for your stomach.
 
Even a small slimy patch is enough reason to throw it away.
 

5. Off or Sour Smell

A fresh summer squash smells mild, almost like nothing at all.
 
If your summer squash smells sour, musty, or just off, it’s past its prime.
 
Trust your nose here because a bad smell is one of the most reliable ways to know if summer squash is bad.
 

6. Dark or Discolored Spots

Dark spots, brown patches, or a dull appearance on summer squash mean it’s declining.
 
Small nicks are fine, but large discolored areas usually mean the summer squash is going bad.
 
If those spots feel soft too, that summer squash is definitely bad.
 

How Long Does Summer Squash Last?

How long summer squash lasts depends on how you store it.
 
At room temperature, summer squash lasts only a couple of days before it starts to soften.
 
In the fridge crisper drawer, fresh summer squash can last about 4 to 7 days.
 
If you’ve cut your summer squash, wrap it tight and use it within 2 to 3 days.
 
Frozen summer squash lasts much longer, often up to 10 to 12 months, but the texture changes after thawing.
 

How to Store Summer Squash So It Lasts Longer

Proper storage keeps summer squash fresh and delays spoilage.
 

1. Keep It Dry

Moisture is the enemy of summer squash.
 
Wipe summer squash dry before storing it, and avoid washing it until you’re ready to use it.
 

2. Use the Crisper Drawer

Store summer squash in a perforated plastic bag inside your fridge’s crisper drawer.
 
The bag keeps humidity balanced while letting some air circulate, which helps summer squash stay firm longer.
 

3. Don’t Stack Them Too High

Piling summer squash on top of each other causes bruising and traps moisture.
 
Lay summer squash in a single layer whenever possible so air can move around them.
 

4. Freeze Excess Squash

If you have more summer squash than you can eat, blanch and freeze it.
 
Blanching stops enzymes that cause summer squash to go bad, and freezing locks in flavor for months.
 

Can You Eat Summer Squash That’s a Little Soft?

Slightly soft summer squash is sometimes still okay to eat.
 
If the soft spot is small and the rest of the summer squash feels firm, cut away the soft part and cook the rest right away.
 
But if the softness is widespread, or if the summer squash is also slimy or smelly, toss it.
 
When in doubt about whether summer squash is bad, err on the side of caution.
 

So, How Do You Know If Summer Squash Is Bad?

Summer squash is bad when it feels soft, looks wrinkled, grows mold, turns slimy, or smells sour.
 
Any one of those signs is enough to know that summer squash has gone bad and should be thrown out.
 
Store summer squash dry in the crisper drawer, use it within a week, and freeze the extras so nothing goes to waste.
 
With these tips, you’ll always know if summer squash is bad before it ever hits your plate.
