How to tell if Greek yogurt is bad – 6 Signs Greek yogurt is bad

If you’re a big fan of Greek yogurt, you may want to know how to tell if greek yogurt is bad? If you’ve got some Greek yogurt that’s been sitting in your fridge for a few days, and you’re not sure if it’s still good to eat, there are a few signs that will tell you if it is or not.

If the yogurt has started to separate into layers, if it smells sour, feels slimy or sticky and if it gives a different color than what you normally see, then it may not be good anymore. You need to always know the state of your Greek yogurt before taking it.

It is not safe to eat bad Greek yogurt. The danger of eating bad greek yogurt is that it could make you sick. If you buy yogurt from a store, you need to make sure that the yogurt has been pasteurized. If it hasn’t been pasteurized, then bacteria like salmonella or listeria can grow in it.

This can cause food poisoning, which can lead to serious illness or even death in some cases.

how to tell if greek yogurt is bad

Your body has built-in defenses against the bad bacteria that can grow in yogurt that has been improperly stored. But if the bacteria get through your body’s defenses, they can cause mild to severe illness.

The symptoms of food poisoning from eating bad yogurt include:

  • Diarrhea
  • Nausea
  • Vomiting

6 Signs Greek yogurt is bad

There are several signs that your Greek yogurt has gone bad, so read on to find out how to tell.

1. The yogurt has mold on it or looks slimy

If the yogurt has mold on it or looks slimy, you should toss it. However, if the mold is just on the surface and you can easily scrape it off, you can still eat the yogurt as long as there isn’t any mold inside the container.

2. Uneven consistency

If your Greek yogurt has an uneven consistency, it may be a sign of spoilage. If it does not have a smooth, consistent texture and is instead clumpy, it could be due to the fact that the dairy product was over- or under-culture during production.

3. Grainy texture

Grainy texture is a common sign of yogurt that has spoiled. An old, sour taste can also be a giveaway. If your Greek yogurt separates and you see large chunks in the bottom of your container, it’s likely gone bad.

4. Sour smell

If your Greek yogurt is sour smelling and tastes terrible, then it has gone bad. That’s because a lot of fruit containing probiotics is required to create the natural “good” bacteria that will keep your yogurt fresh. If you find your yogurt has lost this freshness, toss or donate it immediately.

5. The yogurt is runny

The yogurt is runny because it has been compromised by bad bacteria. Runny yogurt is thinner, looser and often has a foul smell. It may also have a rubbery texture and taste sour or like vinegar.

6. Cloudy or off-color

Cloudy or off-color yogurt might mean that it has gone bad. Check the expiration date on your yogurt container to find its shelf life. If the expiration date isn’t printed on your container, it may be listed on a sticker inside the yogurt cup’s lid.
