Cooking with Blue Cheese: Can You Eat Expired Cheese?

If you’ve ever chuckled at the idea of eating expired or spoiled food, especially something as pungent as blue cheese, it’s probably time to revisit the concept. While you may have heard that some items like dairy products cannot be eaten past their expiration date, is blue cheese one of them?

Believe it or not, blue cheese can still be safe to eat after its expiration date has passed. Providing the cheese is stored correctly and isn’t showing signs of a funky smell or texture, you can eat expired blue cheese without putting your health at risk. However, it’s always best to practice caution when consuming any type of food past its expiration date.

If you’re unsure whether a packaging of blue cheese has gone bad and can no longer be consumed safely, here are some key signs and characteristics to look out for:

  • A sharp odor
  • Slimy texture with bruising
  • Growth or discoloration on the surface
  • A change in taste from its original flavor profile

Generally speaking, if there are any signs of unusual color changes or an overpowering smell present, it would be best to throw the cheese away, despite being past its expiration date. However, as Healthline points out, eating spoiled blue cheese can lead to a case of food poisoning or the accidental consumption of toxic types of mold — meaning it’s important to be able to spot the difference between a good blue cheese and one that’s gone bad.

If stored and handled properly, a wheel of blue cheese should remain fresh in your fridge for up to 3 months after purchase. But once you’re beyond this point, ask yourself: is it really worth taking the risk over something as seemingly insignificant as a block of expired cheese? The answer may vary from person to person — just remember to always err on the side of caution when dealing with consuming outdated items!

Going Bad or Going Home: How to Tell if Blue Cheese is Still Good

It’s important to know how to tell when blue cheese has gone bad, as consuming spoiled cheese can cause serious health issues. Fortunately, there are a few key signs to look out for that will help you determine if your blue cheese has gone bad:

  • Fuzzy White, Green, Pink, or Grey Spots Growing on the Surface: These spots may indicate the presence of mold and mean that it’s time to throw away the cheese.
  • A Strong Ammonia-Like Smell: If you detect an ammonia-like odour on your blue cheese, it’s started spoiling and should be thrown away.

If you notice any of these signs of spoilage on your blue cheese, it is best to discard it immediately. Spoilage can happen quickly with blue cheese so it pays to be diligent in monitoring the freshness of your cheese.

If you notice any discolouration or an unpleasant odour before opening your cheese, don’t take the risk and throw it away immediately. It is always better to be safe than sorry when dealing with food safety!

Blue cheese often spoils very quickly so you should use it within a couple of days of bringing it home from the store. For best results, make sure you store blue cheese in its original packaging in the refrigerator until you’re ready to use it.

Crumbling Around: Testing Crumbled Blue Cheese For Freshness

Cheese can often be difficult to judge when it comes to whether it is spoiled or not. While certain cheeses are obviously off and can’t be eaten, other more subtle changes may take place that are more difficult to recognize. The best way to tell if your blue cheese crumbles have spoiled is with a combination of smell and sight.

Smell, in particular, can be a great indicator when deciding if your crumbles are off. If the blue cheese develops an odd odor it should definitely be discarded. Taste may further confirm what you’ve noticed in the smell, however, this isn’t recommended as consuming spoilt foods carries many risks.

Sight can also provide useful information when determining the status of your crumbles. If anything seems out of the ordinary (such as clumps or color changes) or mold appears, it should be discarded immediately.

It’s important to remember that safety should always come first in deciding whether cheese is safe to consume. To avoiding any dangers associated with spoilt food, always check these four characteristics of blue cheese before eating them:

  • Smell
  • Texture
  • Color
  • Mold

If all of these pieces indicate that the crumbles have spoiled, discard them immediately and try again with a fresh batch next time!
