Does String Cheese Need to be Refrigerated?

String cheese is a lifesaver for those busy weeknights. Who wants to spend time cutting up a cheese block to pack into your kids lunch if you don’t have to? Instead, reach for string cheese. Pre-packaged in individual sticks, this product makes an excellent time saver! Not to mention, you don’t have to wash any dishes. 

String cheese is packaged in single, plastic-wrapped portions to help maintain freshness. The plastic wrapping is easy to tear open, making it an excellent choice for kids lunches!

But, does the packaging of string cheese make it shelf stable? We’ve wondered the same thing. The simple answer is no. 

Keep your string cheese refrigerated! String cheese is traditionally made of mozzarella cheese. Today, you can find many cheese varieties in these tasty little snacks. But don’t be fooled – only the mozzarella varieties develop that stringy texture. (*)

Whether you’re buying mozzarella, cheddar, or anything in between, keep these cheese snacks in the refrigerator. This is important for food safety!

Why, you might ask? Well, the answer may shock you, but… string cheese is real cheese. Many people think that it’s highly processed, due to the fun qualities of the product.  

String cheese will react to heat like any other cheese. Its texture changes, becoming soft and wet, making it rather unappetizing.

Since string cheese is real cheese, you can feel good about what your family is consuming! Just make sure to put an ice pack in the lunch kit to keep your string cheese cool. This will not only save the taste and texture, but also prevent food borne illness. (*)

What is the Shelf-life of String Cheese?

The stringy, peelable texture of string cheese is what deceives people when it comes to storage requirements. It nearly seems like string cheese is not real cheese. 

String cheese is, however, very real. It is simply low moisture mozzarella cheese, stretched out multiple times. This is what gives it the unique, stringy texture that we all know and love. Plus, it makes this fun cheese snack surprisingly healthy! 

If you have kids, you surely go through tons of string cheese! So, how long does string cheese last? Is it something you should stock up on during a sale?

As a general guideline, you should always refer to the best before date on the package. Don’t buy too many if they are going off in a short time frame. This is often the reason for sales, so be sure to check this before purchasing!

Once opened, you should eat your string cheese rather quickly. Within a few days is best. It can last 5-7 days once opened, if properly stored. 

If storing open string cheese, follow these recommendations:

  • Saran wrap the leftover string cheese
  • Store in a tightly sealed container
  • Transfer to the fridge immediately

If your kids bring home a half eaten cheese string that has sat in a lunch kit all day, it’s best to toss it. Better safe than sorry. It’s not worth the risk of getting sick.
