Ricotta cheese is a versatile ingredient that can be used in both sweet and savoury dishes. However, it is a fresh cheese with high moisture and low salt content, so it can go bad quickly. To avoid food waste, it's important to know how to identify if ricotta cheese has gone bad. The key indicators of spoilage are changes in appearance, smell, and taste. If you notice any signs of mould, discolouration, excess liquid, or texture changes, it's best to discard the cheese. Additionally, trust your senses; if the ricotta smells or tastes sour or off in any way, it's no longer safe to consume. To prolong the shelf life of ricotta cheese, proper storage is crucial. It should be stored in airtight containers in the fridge at a temperature between 35-40°F. For longer storage, ricotta can be frozen for up to three months, although texture changes may occur upon thawing.

Shelf life: how long does ricotta cheese last?
Ricotta cheese is a soft, spreadable cheese with a smooth, creamy texture and a delicate, milky, sweet flavour. It is a whey cheese made by reheating the leftover whey from producing other cheeses like mozzarella or provolone. Its high moisture content creates a breeding ground for bacteria, so it doesn't last as long as harder cheeses.
An unopened container of ricotta will generally last around two weeks in the fridge. However, once opened, ricotta will only last about a week due to air exposure. To extend its life, you can freeze ricotta, which will then last for around two to three months. However, freezing may negatively affect the texture of the cheese, making it clumpy and less smooth.
To check if ricotta cheese has gone bad, look out for any signs of mould, as well as any changes in appearance, odour, or taste. Ricotta doesn't have a strong smell, so any foul odour is an indication that it has gone bad. If there is any liquid on top of the cheese, this could also be a sign that it has spoiled.

Storage: how to store ricotta cheese
Ricotta cheese is a fresh, soft, and perishable food with a high moisture content and low salt content. This means it needs to be stored correctly to keep its nutritional and organoleptic properties intact and to be consumed safely.
When storing fresh ricotta in the refrigerator, it should be kept at a temperature of around 4°C. The packaging must be intact, and once opened, it should be properly closed or stored in a container with a tight seal. Fresh ricotta can be stored in the refrigerator for 2-3 days, but if it is well-packed, it can last up to 4-5 days. However, it is important to always respect the expiry date indicated on the food label.
To extend the shelf life of ricotta, it can be frozen. To do this, portion the ricotta into the amount needed for a single meal, as constant thawing and refreezing should be avoided. Remove any excess moisture by pressing the cheese with paper towels, then wrap the portions tightly in plastic wrap, ensuring no air is trapped. Place the wrapped cheese in a freezer bag, remove any air, label it, and freeze for up to two months. To thaw, place the amount needed in the refrigerator for about 24 hours, and use within two days. Do not refreeze thawed ricotta.
It is important to note that freezing may affect the texture and taste of ricotta, making it less suitable for recipes where it is the star ingredient. Additionally, seasoned ricotta may not freeze well, and some seasonings may not preserve the cheese effectively.

Appearance: what to look for
Ricotta is a soft cheese with a smooth, creamy texture and a delicate, milky, sweet flavour. Unlike harder cheeses, soft cheeses like ricotta are more perishable and susceptible to spoilage, so it's important to inspect their appearance before consumption.
Firstly, check for any signs of mould. According to the USDA, while it is acceptable to cut off mouldy parts from hard cheeses, the same does not apply to soft cheeses like ricotta. Mould can penetrate beneath the surface of soft cheeses, so even if you remove the visibly mouldy parts, you may still get sick from consuming the rest. Mould on ricotta can be green, blue, or soft pink in colour.
Discolouration is another key indicator of spoilage. Fresh ricotta is typically creamy white in colour, so if your ricotta has turned yellowish or brown, it's best to discard it.
Excess liquid on top of the cheese is also a sign of spoilage. While a little liquid on top is normal, a significant layer of water indicates that your ricotta has gone bad.
Other signs of spoilage include texture issues such as graininess or lumpiness. Fresh ricotta has a smooth, creamy texture, so any deviations from this standard may indicate that your ricotta has gone bad.

Smell: how to sniff test
Ricotta cheese is a mild, soft cheese that has a very subtle smell, usually smelling slightly sweet and mostly of milk. Fresh ricotta should not smell sour, fermented, rancid, or like ammonia. If your ricotta has any of these odours, it has likely gone bad and should be discarded.
Ricotta is highly perishable, so it should always be stored in the refrigerator at 35°F to 40°F (1.6°C to 4.4°C). It should be kept in its original packaging or an airtight container to limit exposure to air and moisture, which can cause it to spoil faster. Even with careful handling, an opened package of ricotta will only last about one to two weeks, according to the U.S. Department of Agriculture. To be safe, discard ricotta cheese that has been in your fridge for longer than two weeks. If you can't remember when you bought it, throw it out.
The "use-by" date on the package is also a helpful guideline for keeping ricotta. An unopened container may stay fresh for up to two weeks past this date. However, if the date has long passed, the cheese is likely no longer good.
In addition to smell, there are other signs that can indicate ricotta cheese has spoiled. Discolouration, such as a yellowish or brownish hue, or the presence of mould, black spots, or water on the cheese, are all signs that it has gone bad. A change in texture, such as a grainy or crumbly consistency, can also signify that the ricotta is no longer fresh.

Taste: when to throw it out
Taste is a key indicator of whether ricotta cheese has gone bad. Ricotta has a delicate, milky, sweet flavor. If it doesn't taste as it should, it's best to stay on the safe side and throw it out.
Ricotta doesn't have a particularly distinct smell, but once it begins to smell sour, that's a sign it's gone bad. If it smells foul or off in any way, then it's time to throw it out. Trust your nose: if something smells off, it's because it is off.
If you're unsure whether your ricotta is still edible, inspect it with your eyes and nose. If there's any sign of mold, that's bad news, and you'll have to throw the whole thing out. While you can cut the moldy parts off hard cheeses, soft cheeses like ricotta don't have the same benefit, according to the USDA. Mold on ricotta can be green, blue, or soft pink. If the ricotta has turned yellowish or brown, that's another sign of spoilage.
Other signs of spoilage include discoloration, excess liquid, and texture issues (graininess, lumpiness). If ricotta cheese has been stored properly, it should last about one week in the fridge.
