What You'll Learn
Check the colour—if it's changed, it's gone bad
Colour is a key indicator of whether your nacho cheese has gone bad. Nacho cheese, or queso, is typically white, so any discolouration or change in hue is a warning sign. If you notice any patches of green, for example, this is a sure sign of mould and the entire batch should be discarded.
The rate at which the colour of nacho cheese changes depends on several factors. Firstly, the type of cheese dip matters. For example, store-bought cheese dips tend to last longer than homemade queso due to the added preservatives in the former. Secondly, the storage method is crucial. If unopened and stored in an airtight container, queso can last for months past its best-by date at room temperature. However, once opened, it should be refrigerated and will only stay fresh for about one to two weeks.
Homemade queso or cheese dips from restaurants are more perishable, lasting only up to four days in the refrigerator if stored properly in airtight containers. If left at room temperature, these varieties of nacho cheese should be discarded after two hours to prevent spoilage.
In addition to colour changes, keep an eye out for alterations in texture. If your nacho cheese develops slime, oil, or a bloated package, discard it immediately. Bad queso can cause food poisoning and ailments due to harmful bacteria such as listeria and salmonella, so it's always better to be cautious and err on the side of safety.

Texture—if it's slimy, oily, or the packaging looks bloated, discard it
One of the ways to tell if nacho cheese has gone bad is by checking its texture. If you notice any sliminess, oiliness, or if the packaging looks bloated, discard it immediately. Bad nacho cheese has been associated with food poisoning and ailments due to listeria, salmonella, and other harmful germs. Therefore, it is always better to err on the side of caution and throw it out if you have any doubts about its freshness.
Nacho cheese, or queso, can be store-bought or homemade. Store-bought queso is typically made with processed cheeses and preservatives, giving it a longer shelf life than its homemade counterpart. However, once the package is opened, the clock starts ticking on its freshness. Store-bought queso can be safely stored in the refrigerator for about one to two weeks before it starts to spoil.
To maximize the shelf life of nacho cheese, proper storage is crucial. It should be stored in an airtight container in the refrigerator. If you don't have access to a refrigerator, place it in an airtight container and keep it in the coolest area possible. An airtight seal is essential to prevent air from entering the container, which can accelerate the deterioration process.
In addition to texture changes, there are other signs to look out for when determining if your nacho cheese has gone bad. Colour changes can be an indicator of spoilage. Additionally, always refer to the expiration date and storage directions provided by the brand. Some brands, like Frito Lay, offer specific recommendations for storing their products after opening.
Remember, eating even a small amount of spoiled nacho cheese can be unsafe. By paying attention to the texture, colour, expiration dates, and proper storage practices, you can ensure that you avoid consuming any cheese that has gone bad.

Smell it—if in doubt, a bad smell means it's off
Smell is one of the most important senses when it comes to food safety. If you're unsure whether your nacho cheese is still good to eat, give it a good sniff before digging in. If it smells off, trust your nose and discard it.
The sense of smell is highly sensitive and can detect even subtle changes in food that may indicate spoilage. Nacho cheese, in particular, is prone to rapid deterioration due to its dairy content and exposure to air. Even when stored properly in the refrigerator and in an airtight container, nacho cheese can only be kept for a limited time—typically up to two weeks for store-bought cheese dip and just four days for homemade queso or restaurant leftovers.
The "sniff test" is a simple yet effective way to assess the freshness of your nacho cheese. A bad smell is a clear indicator that the cheese has gone beyond its shelf life and is no longer safe to consume. Spoiled nacho cheese can be dangerous, as it may contain harmful bacteria such as listeria and salmonella, which can cause food poisoning and other ailments.
It's important to remember that smell is not the only factor in determining whether nacho cheese has gone bad. Visual and textural changes can also provide clues. For example, if the cheese has changed colour, developed a slimy texture, or has visible oil separation, it should be discarded immediately. However, when in doubt, the smell test can be a quick and reliable way to make a decision.
In conclusion, when it comes to nacho cheese, always trust your nose. If it smells questionable, it's best to err on the side of caution and dispose of it. While it can be disappointing to part with your favourite snack, avoiding potential foodborne illnesses is well worth the sacrifice. So, the next time you're unsure about the freshness of your nacho cheese, take a cautious whiff and make an informed decision for the sake of your taste buds and tummy.

Storage—keep opened jars in the fridge
To keep opened jars of nacho cheese fresh, it is important to store them in the fridge. This will help to prolong the freshness of the cheese dip and prevent spoilage.
Firstly, it is crucial to use a quality airtight container to store the opened jars of nacho cheese in the refrigerator. Air is the enemy of freshness when it comes to cheese dips, so ensuring that the container is airtight is essential to maximise its shelf life and keep out contaminants. This will prevent air from getting inside and causing the cheese to spoil.
The refrigerator temperature also plays a vital role in maintaining freshness. To optimise the shelf life of nacho cheese, the refrigerator should be set at 39 degrees Fahrenheit (approximately 4 degrees Celsius). At this temperature, the cheese will remain fresh and safe to consume.
In addition to using airtight containers and maintaining the correct refrigerator temperature, it is recommended to follow the storage directions provided by some brands. For example, companies like Frito Lay (the parent company of Tostidos) and Pace offer recommendations on how long to keep the jars once they have been opened. Following these guidelines can help ensure that the nacho cheese remains edible and safe to enjoy.
By storing opened jars of nacho cheese in the fridge, you can typically expect it to remain fresh for about one to two weeks. However, it is always advisable to give the cheese a quick smell test before indulging, as it can turn bad quickly. If it passes the sniff test, you can confidently dip your nachos and enjoy the rich, gooey goodness without worrying about spoilage.

Expiry—store-bought queso lasts 2 months unopened, 2 weeks opened
Store-bought queso typically has a shelf life of about two months if it is unopened and stored in a pantry. However, once the jar is opened, the queso should be stored in the refrigerator and consumed within one to two weeks.
To ensure the safety of your nacho cheese, it is important to follow proper storage practices. Always keep the lid of the jar securely closed when storing it in the fridge to avoid contamination from other foods. If the original lid is not available, cover the top with plastic wrap and secure it with a rubber band or transfer the queso to an airtight container.
Additionally, it is recommended to keep track of when the jar was first opened. This will help you determine how much time has passed and whether the queso is still within its safe consumption period.
One of the simplest and safest methods to determine if your queso has expired is to use your sense of smell. Open the jar and take a cautious whiff. Fresh queso should have a rich and cheesy aroma. If, instead, you detect a rancid, sour, or ammonia-like odour, it is best to discard the contents as they have likely spoiled.
Visual and textural cues can also indicate whether your queso has gone bad. When fresh, it should appear thick, creamy, and glossy. If it has spoiled, you may notice separation, clumpiness, darkening of colour, or the presence of mould. Any of these signs indicate that the queso is no longer safe to consume and should be discarded.
