A sliced deli cheese is one of the most convenient and tasty additions to any meal, snack, or recipe among many kinds of cheese. But how long is sliced deli cheese good for?
Let’s look at its shelf life and provide some tips on storing it. Read on.
How Long Will Sliced Deli Cheese Last?
Generally, sliced deli cheese will remain safe for up to 2 to 3 weeks if stored properly and immediately after purchase.
Once you have opened the package, use the cheese slices within 5 days to 1 week to get the best quality.
However, some factors can affect its shelf life, such as storage temperature, packaging type, and firmness.
To maximize the shelf life of your sliced deli cheese, do not open its packaging until ready for use or consumption, and store it in the fridge right after purchasing from the store.
Sliced deli cheese can still be safe for consumption even if passed the “sell-by” in the packaging, provided that it is stored properly and there are no signs of spoilage.
It’s generally known that harder types of cheese last longer than softer ones. Because softer cheese has more moisture content and higher moisture, it will likely spoil sooner.

Sliced Deli Cheese Shelf Life
Sliced deli cheese typically shortens its shelf life once opened. It should be consumed within 7-10 days to maintain quality and avoid contamination or spoilage.
To ensure the best quality of your product, store it in an airtight container or resealable bag in the refrigerator after opening it and consume it as soon as possible for optimal taste and texture.
Unopened sliced deli cheese has a longer shelf life when stored appropriately. When kept in the refrigerator, unopened packages of sliced deli cheese can last up to three weeks before they spoil.
Also, proper storage techniques, such as keeping the cheese sealed tightly in its original packaging and at the right temperature, will help extend its shelf life even further.
Like most dairy products, sliced deli cheese doesn’t last well at room temperature or in warm places such as pantries.
Depending on the type of cheese, it can last for a few days or a week if unopened from tight packaging.
But once opened, sliced deli cheese should not be at room temperature for more than four hours to keep it safe from bacterial growth and spoilage.
The most common lifespan of a refrigerated sliced deli cheese is about 2-3 weeks, and it should be stored between 35 and 45 degrees Fahrenheit.

The best way to store it is to left unopened from the packaging. However, if you happen to open it, rewrap it with wax paper or plastic wrap and store it in a crisper drawer where the temperature is cold and stable. 
Freezing sliced deli cheese is a great way to store it for a longer period.
Frozen sliced deli cheese lasts around 6 to 8 months or even longer. However, freezing it may cause to affect its flavor and overall quality.
To freeze sliced deli cheese, wrap it with plastic freezer wrap or aluminum foil, and place it in a heavy-duty freezer bag or freezer-safe container.
Once thawed, it can remain in the fridge for 3-4 days.
How Long Does It Last After the Sell-by Date?
Sliced deli cheese can still be safe for consumption even a month past the “sell-by” date.
But before using or consuming, make sure to check first for any signs of spoilage.
The “sell-by” date does not mean your sliced deli cheese is unsafe past that time frame, but it’s just a mere suggestion that your cheese is at peak quality during that time.
How To Tell If It Has Gone Bad
The appearance is one of the most obvious indicators that something isn’t right with your cheese.
If the color of your cheese has changed from its original off-white or yellowish hue and become darker or more green or orange in certain spots, then it’s time to throw it away.
Another sure sign that your deli cheese has gone bad is if molds have started growing on its surface.
You may notice white dots or fuzzy patches on top of the slices – these are all indications that the product should be discarded immediately.
Lastly, if your deli cheese has a strong smell that you wouldn’t typically associate with it, this is another sign that the product has gone bad.
If the aroma is sour or off-putting in any way, then it’s best to discard the slices straight away.
How do you store sliced deli cheese?
Sliced deli cheese is best stored in the refrigerator with its original packaging unopened. With a constant temperature between 35 to 45 degrees Fahrenheit, it should last for about 2-3 weeks.
However, if you wish to store it longer, then freezing it is best.
Make sure to wrap it with wax paper or plastic freezer wrap and place it in freezer bags or freezer-safe containers before freezing for optimal storage.
How do you keep sliced deli cheese from molding?
The best way to keep sliced deli cheese from molding is with a proper storage method. Keep it in cold places such as a fridge or freezer.
Do not let it sit at room temperature or in warm places for too long to avoid the growth of molds and bacteria.
Sliced deli cheese is a convenient and tasty addition to any meal. However, its shelf life is much shorter than that of block cheese.
It’s generally safe for consumption for up to 2-3 weeks and can still be safe even past the sell-by date if stored in the fridge properly and immediately after the purchase.
On the other hand, freezing it will last up to 8 months but may become crumbly and lose some of its flavor.
Knowing the proper storage method and shelf life of sliced deli cheese can help you ensure that you are eating it safely and healthily without having to worry about spoilage.
