What Happens When You Eat Expired Cans!

We’ve all been there—digging through the pantry, finding cans lurking in the back that have long passed their expiration date. Sometimes, in a rush or curiosity, you might wonder: “Is it really bad to eat expired canned food?” Or worse, you accidentally eat some and ask yourself, “What happens now?”

Let’s unpack the truth about expired canned goods, what risks they pose, and how to stay safe.

Understanding Expiration Dates on Cans

First, it’s important to know that canned foods often have two dates: “Best by” and “Use by.” These are more about quality than safety. Most canned foods stay safe to eat for years if the can is intact and stored properly, but the taste, texture, and nutrition might deteriorate over time.

What Can Go Wrong?

Eating expired canned food isn’t always dangerous, but it can be risky if:

The can is damaged: Bulging, leaking, rusted, or severely dented cans can allow bacteria to enter.

There’s a bad smell: If the food smells off or sour, that’s a red flag.

The food looks strange: Discoloration, mold, or unusual textures mean it’s time to toss it.

The Big Risk: Botulism

One of the most serious risks from eating spoiled canned food is botulism, a rare but potentially fatal illness caused by toxins produced by Clostridium botulinum bacteria. This bacteria thrives in low-oxygen environments like canned foods when the can is compromised.

Symptoms of botulism include nausea, vomiting, weakness, difficulty speaking or swallowing, and even paralysis. If you suspect botulism poisoning, seek emergency medical help immediately.

What Happens If You Eat Expired Canned Food?

If the can and food are fine: You’ll probably be okay, just maybe notice a change in taste or texture.

If the can is damaged or food is spoiled: You might get food poisoning symptoms such as stomach cramps, vomiting, diarrhea, or worse if botulism is involved.
