What Will Happen If You Eat Smelly Cheese?

It depends.

Aside from your typical kitchen conundrums such as what to do with undercooked cheesecake or what to do with undercooked brownies, what will happen if you eat smelly cheese just might top your list of kitchen questions because it could have a direct affect on your health.

We hear you! But just because your cheese stinks, doesn’t mean it’s old.

There are many kinds of cheese, including parmesan cheese, that have a naturally stinky odor.

If, however, your cheese smells particularly strong or has a rancid odor, you may want to check the expiration date.

If you find that your cheese is indeed old, you may experience the following symptoms as a result of eating old cheese:

  • Abdominal Pain
  • Cramping
  • Loose Stools
  • Vomiting

What Should I Do If I Ate Bad Cheese?

If you eat bad cheese, you may not need to do anything. Unless you have severe stomach or gastrointestinal issues, it isn’t necessary to seek medical help.

If, however, you find that you are vomiting, experiencing loose stools, or are noticing other unsavory symptoms from having consumed bad cheese, you may consider avoiding foods for a few hours then following up with something dry and bland–such as toast, rice or crackers–until you can get your stomach settled.

What Happens If You Eat Bad Cheese?

Depending on how old the cheese was, you could end up with food poisoning.

Though eating moldy or otherwise expired cheese doesn’t always hurt you, you could end up experiencing digestive issues as a result of your consumption of the bad cheese.

Never continue to eat cheese that is making you sick, even if it seems okay in terms of taste and texture.

How Long After Eating Bad Cheese Do You Get Sick?

Eating bad cheese can manifest gnarly symptoms within 24 hours of consumption.

If you suspect that your cheese is the culprit, quickly discard it, especially if there is a risk that others living with you might consume the cheese as well.

If your cheese seems fresh and tastes okay, make sure it is actually the cheese that has caused you to become ill and not something else.

Can Bad Cheese Make You Sick?

Yes, it can.

Bad cheese can make you sick the same way any expired, old, or rotten food can. The symptoms that present themselves are typically referred to as “food poisoning”.

If you have a high fever, bloody stool, or if you cannot seem to keep down liquids, you may want to give your local doctor a call to see what can be provided for treatment.

Is It Bad to Eat Cheese That Smells Bad?

Not necessarily.

Remember, cheese that smells bad is a common and natural occurrence, and thus, isn’t always a cause for concern in most cases.

Still, there are times when the odor of cheese may seem particularly strong or “off” in some way. In this case, we would recommend that you avoid eating the cheese.

Cheese Smells Sour

If you smell your cheese and it smells sour, it could be that your cheese has gone bad.

Because cheese is a dairy product, the sour smell it produces when it goes bad can help you determine when it’s time to throw your cheese away.

Be sure, however, that it isn’t just you; sometimes illness and pregnancy can distort your sense of smell making the cheese smell like something it actually doesn’t.
