Blue cheese dressing is a delicious condiment that can elevate any salad, but it's important to know when it's gone bad. While commercially packaged blue cheese salad dressing will have a Best By or Best Before date, this is not a safety date but rather an estimate of how long the product will remain at peak quality. To maximize the shelf life of opened blue cheese salad dressing, it's important to keep it refrigerated and tightly covered. A freshly opened blue cheese dressing will be tastier than one that has been open for several months, but proper storage can extend its shelf life. If you're unsure whether your blue cheese dressing has gone bad, look out for signs of spoilage such as a slimy texture or an unusual smell. Trust your senses, and if it looks or smells weird, it's best to discard it.

What You'll Learn
Blue cheese dressing will last 6-9 months in the fridge
Blue cheese dressing will last for quite a long time in the fridge, typically between 6 to 9 months. This is because the blue mould in the cheese produces ammonia, which reduces the acidity of the cheese over time, inhibiting the growth of other bacteria. This means that blue cheese dressing can be safely consumed for many months after opening, as long as it is stored in the refrigerator.
However, it's important to note that the quality of the dressing may deteriorate over time, and a freshly opened bottle will taste better than one that has been open for several months. Additionally, it's always a good idea to inspect any food product before consuming it, especially if it is past its best-before date.
When it comes to blue cheese dressing, the most important indicators of spoilage are smell, taste, and appearance. If the dressing smells foul or "funny," it is likely spoiled and should be discarded. Similarly, if the taste has become too strong or unpleasant, it is best to err on the side of caution and throw it out.
In terms of appearance, blue cheese dressing should not have any fuzzy or coloured mould other than the typical blue or blue-green mould that is characteristic of the cheese. If you notice any grey, green, pink, or white mould, spots, or fuzz, it is best to discard the dressing. Additionally, a slimy or gritty texture can indicate spoilage.
To maximise the shelf life of blue cheese dressing, it is important to practise proper storage. Make sure to seal the bottle tightly and store it in the refrigerator. It is also recommended to wrap the cheese in parchment or wax paper before placing it in the fridge.

An unopened package will last 12-18 months
An unopened package of blue cheese dressing will generally last for about 12 to 18 months, provided it is stored properly and the package is undamaged. The dressing is typically safe to consume even after the expiration date on the package, as this date is only the manufacturer's estimate of how long the product will remain at peak quality. That being said, it's important to inspect the dressing before consuming it if it has exceeded its best-before date.
Firstly, check the appearance of the dressing. Look for any signs of mold or discoloration, particularly yellow or brown tints. If the dressing has changed colour or developed a yellowish or brownish hue, it should be discarded.
Secondly, take a whiff of the dressing. A sour, rancid, or otherwise unpleasant odour indicates that the dressing has gone bad. If the dressing smells "funny" or foul, it's best to get rid of it.
Thirdly, examine the texture of the dressing. If it has become excessively watery, lumpy, or chunky, or if there is separation in the dressing, it has likely spoiled.
Finally, if the dressing passes the above tests, you can consider tasting a small amount. If everything seems okay, it should be safe to consume. However, if you notice any unpleasant tastes or textures, it's best to discard the dressing.
It's important to note that these tests are not exhaustive, and other factors such as proper storage and refrigeration play a crucial role in ensuring the safety of blue cheese dressing. Always store the dressing in an airtight container and refrigerate it immediately after opening to slow down the growth of harmful microorganisms.

Check for moulds other than the blue variety
Blue cheese is known for its pungent taste and smell, which is due to the edible blue mould that it contains. This mould is perfectly safe to eat. However, other types of mould can indicate that your blue cheese dressing has gone bad.
When checking your blue cheese dressing for mould, look out for grey, green, pink, or white spots, or fuzz. These colours indicate that the cheese has gone bad and should be discarded. Good blue cheese should have blue or green mould, and a moist, tangy texture. If the cheese appears slimy, gritty, or fuzzy, it has likely gone bad.
The smell of blue cheese can also indicate whether it has gone bad. Fresh blue cheese has a strong scent, but this changes as it starts to spoil. If your blue cheese dressing smells like ammonia, or stale, it has likely gone bad. It is a good idea to smell the cheese when you first open it, so you know what it smells like when it is fresh.
Tasting the blue cheese dressing is another way to check if it has gone bad. Fresh blue cheese has a strong, sharp taste, whereas old cheese becomes biting when it starts to spoil. If the blue cheese is too strong to enjoy, it has likely gone bad. However, it is important to note that tasting potentially spoiled food can be dangerous, and should be avoided if the cheese looks or smells off.

If it smells weird, throw it out
Blue cheese is known for its pungent taste and scent, which is due to the edible mold it contains. However, just like any other cheese, blue cheese can spoil and develop harmful mold. The best way to tell if your blue cheese dressing is bad is to use your sense of smell.
If your blue cheese dressing smells weird or off, it's best to throw it out. The blue mold in cheese produces ammonia, which reduces the acidity over time. Once the acidity is low enough, other bacteria can start to grow, causing the cheese to spoil. While the mold in blue cheese is edible and safe to consume, harmful mold can develop if the cheese is not properly stored or has passed its peak quality.
It's important to note that commercially packaged blue cheese dressing typically carries a "Best By," "Best if Used By," "Best Before," or "Best When Used By" date. These dates are not safety dates but rather the manufacturer's estimate of how long the dressing will remain at peak quality. Properly stored, unopened blue cheese dressing will generally stay at best quality for about 12 to 18 months. Once opened, it will typically last for 9 to 12 months, and can even keep for an extra month or so if stored properly.
To maximize the shelf life of opened blue cheese dressing, it should be refrigerated and tightly covered. Even when stored properly, blue cheese dressing will eventually spoil. If your blue cheese dressing has been continuously refrigerated and is within the expected shelf life, but still smells strange, it's best to discard it.
In addition to smell, there are other signs that your blue cheese dressing may be bad. If the dressing has developed mold (other than the blue mold), changed color, or has a slimy or fuzzy texture, it should be discarded. Trust your senses and if something seems off, it's better to be safe than sorry.

If the texture is slimy, gritty or fuzzy, it's bad
Blue cheese dressing is a tasty treat, but it can go bad. It's important to know how to spot the signs of spoilage to avoid any unpleasant experiences. One key indicator of spoilage in blue cheese dressing is a change in texture. If the texture becomes slimy, gritty, or fuzzy, it's a sure sign that your dressing has gone bad and should be discarded.
Slime is a breeding ground for bacteria, which can lead to foodborne illnesses. It's always best to err on the side of caution and dispose of any food with a slimy texture, especially if it's accompanied by an unusual smell. Gritty textures can indicate that the dressing has gone bad or that it has started to crystallize due to temperature changes. While crystallization is not harmful, it affects the taste and texture of the dressing, making it less appealing.
A fuzzy texture on blue cheese dressing is a definite sign of mould growth. Mould can produce toxic substances called mycotoxins, which can be harmful to humans. Even if the mould is not toxic, it can still spoil the taste and make the dressing unpleasant to consume. It's always recommended to discard mouldy food products to stay on the safe side.
To prevent your blue cheese dressing from spoiling, proper storage is essential. Store-bought blue cheese dressing should be refrigerated and tightly covered to maximize its shelf life. An unopened package can last for about 12 to 18 months, while an opened package typically has a shelf life of 6 to 9 months. However, it's important to note that these are estimates, and the actual shelf life may vary depending on various factors, including storage conditions and the ingredients used.
Always inspect your blue cheese dressing before consumption. If you notice any textural changes, such as sliminess, grittiness, or fuzziness, discard it immediately. Trust your senses and remember that it's better to be safe than sorry when it comes to consuming potentially spoiled food products.
