Generally, butter can be stored in the refrigerator for up to 3 to 4 weeks. However, it can still be safe to use beyond this time if handled correctly. Once opened, store the butter in a covered container or resealable bag, and use within one to two weeks.
Salted butter can usually last a little longer, as the salt helps to prevent bacteria, but you should still check for signs of spoilage before eating. Additionally, clarified butter or ghee has a longer shelf life than regular butter and can be stored for up to six months.
It is best to wrap it tightly in a plastic wrap before storing it in the refrigerator.

Does butter go bad in the fridge?
Yes, butter can go bad in the fridge. Generally, it has a shelf life of about a month, so it’s best consumed shortly after purchasing. To keep butter fresh for as long as possible, it should be tightly sealed or covered with a lid to prevent air exposure, as this will cause it to go bad more quickly.
Additionally, the butter should not be stored near foods with strong odours, as the flavour can be absorbed and affect the taste of the butter. If you notice an off odour or taste when consuming the butter, it is best to discard it and get a new supply.
How do you know if butter has gone bad?
First, you can look for signs of spoilage, such as discoloration, a sour smell, or an oily texture. If the butter has any of these characteristics, it has likely gone bad and should be discarded. Another way to determine if butter has gone bad is to taste it.
If the butter has an off flavor or a strong smell, it has most likely spoiled. Additionally, if butter has been left out of the refrigerator for a prolonged period of time, it can become rancid. If it smells musty or acrid, it has probably gone bad and should be discarded.
Finally, if butter has been stored for a long period of time, it can develop mold or fungus. If signs of mold are present, the butter should not be eaten.
Does butter really expire?
Yes, butter does expire. Unsalted butter generally lasts for 2 to 3 months in the refrigerator, while salted butter can last up to 6 months. On the other hand, clarified butter can last up to one year stored in the refrigerator and up to two years when stored in the freezer.
It’s important to remember that butter may start to spoil before its expiration date, so keep an eye out for signs of spoilage like a sour smell, change in colors, slime, or mold. Once you notice any of these signs, throw out the butter immediately.
What does rancid butter smell like?
Rancid butter has a strong, sour, or unpleasant odor. It may smell like vinegar, sour milk, or cheese. Generally, it smells “off”, and may have a strong odor of oxidation or spoilage. It also often smells sour, like fermenting, and may have a slightly metallic or fishy odor.
From a taste perspective, it may have a sour, metallic flavor, or have an acidic aftertaste.
Can rancid butter make you sick?
Yes, rancid butter can make you sick. It can contain microorganisms or toxins that can make you ill. For example, the fat and protein content of butter makes it vulnerable to spoilage. When butter goes rancid, bacteria and molds produce toxins that can have a negative effect on your digestive system.
Eating rancid butter can cause nausea, vomiting, and diarrhea, as well as other foodborne illnesses. These illnesses can range from mild to severe, depending on how much rancid butter you ate. Even if you don’t get sick, consuming rancid butter on a regular basis can lead to an impaired digestive system due to the bacteria and mold present.
Therefore, it’s important to be aware of how long butter has been sitting in your fridge and pay attention to any changes in its color, taste, and smell. If you think the butter may have gone bad, it’s best to play it safe and throw it out.
Is it OK to eat expired butter?
No, it is not OK to eat expired butter. Eating expired butter can make you sick because being exposed to bacteria and other microorganisms can result in foodborne illnesses. This can cause nausea, vomiting, diarrhea and other related symptoms.
The texture and flavor of the butter may change as well, which makes it even less appetizing. It is best to check the expiration date of the butter before consuming it and if the butter is past its expiration date, it’s always best to discard it.
Can you get sick from unrefrigerated butter?
Yes, it is possible to get sick from unrefrigerated butter. Raw dairy products like butter can contain bacteria that can cause food poisoning if the dairy products are not stored correctly. If raw butter is left out at room temperature for too long, bacteria like Salmonella and E.
coli can begin to grow. These bacteria can make people very ill, with symptoms such as abdominal distress, nausea and vomiting, fever, and diarrhea. It is therefore important that butter and other perishable dairy products are stored in the refrigerated to ensure their safety.
Can you cook with rancid butter?
No, using rancid butter to cook is not recommended. Rancid butter can contain bacteria that can cause food-borne illnesses. It can also give your food a bitter, sour, or off-taste that can ruin your dish.
When butter is used in cooking, it’s best to be consumed within several months of the purchase date. If your butter has been stored in a warm area, has become soft or mushy, or smells sour, it has most likely gone rancid and should be discarded and replaced.
What type of reaction has taken place when butter has become rancid?
When butter has become rancid it has undergone a process known as “lipid oxidation”. This is a chemical reaction caused by fat molecules which are exposed to oxygen and heat, breaking down into other compounds and producing off-flavors.
The process is exothermic (heat-producing), and it can cause changes in the fat’s color, odor and taste. As the amount of oxidation increases, the butter may have a sour or rancid aroma and taste. The meat of the reaction is that the rancid butter is actually not harmful to eat and it cannot cause disease.
However, it does not offer beneficial nutrients, can change the flavor and taste of food, and can make it less enjoyable. Therefore, it’s best to store butter properly, avoid overheating it, and discard it if it has spoiled.
Why do I get sick after eating butter?
It’s possible that you get sick after eating butter because you are suffering from an allergy or intolerance to dairy products, which includes butter. Symptoms of an allergy or intolerance to dairy products can include nausea, vomiting, abdominal pain, bloating, and diarrhea.
If you are experiencing these symptoms after eating butter, it is possible that you are allergic or intolerant to dairy.
In some cases, it may not be an allergy or intolerance, but simply an issue with how much fat and cholesterol are in butter. Consuming large amounts of butter can lead to gastrointestinal distress, particularly if it is eaten on an empty stomach.
The high levels of fat can cause digestive issues, such as nausea and stomach pain.
Another possible cause of getting sick after eating butter is that it isn’t being stored properly. Dairy products can spoil if stored at room temperature or in conditions where they are exposed to heat and light.
Bacteria in the butter can cause food poisoning, which can lead to vomiting, stomach pain, and other symptoms.
It is important to talk to your doctor if you are consistently getting sick after eating butter. They can examine your symptoms and determine if you have an intolerance or allergy to dairy. They can also recommend dietary changes to reduce your risk of getting sick.
Can refrigerated butter go bad?
Yes, refrigerated butter can go bad. Unopened butter typically has a shelf life of up to a month if kept refrigerated. However, once you open the butter, the shelf life will be much shorter as it can be exposed to bacteria that have been circulating in the air.
To ensure the butter remains safe to eat, it is important to store it in an airtight container and replace it after three to four weeks if it hasn’t been used. In addition, it is important to check the expiration date when purchasing butter from the grocery store.
If the butter has a “best by” date that is passed, do not purchase it as it is likely already spoiled. It is also helpful to store butter in the back of the refrigerator where it will remain the coldest and slow the spoiling process.
How long before butter goes rancid?
The shelf life of butter depends on the type and condition of the butter. Generally, butter stored at room temperature can last for about one to three weeks before going rancid. However, when stored in the refrigerator, unsalted butter can last up to four months, while salted butter can last up to three months.
For longer-term storage, butter can be frozen for up to six months; however, freezing can affect the texture and taste of the butter, so it is best to use it soon after thawing. Additionally, it is important to store butter in a sealed container or wrapped tightly in plastic wrap to help keep it fresh.
Eventually, however, butter will go bad regardless of how it is stored. It is important to check the scent and color of the butter regularly to ensure it hasn’t gone rancid.
Should I throw away expired butter?
Yes, you should throw away expired butter, as it no longer has the same level of nutrition and can cause adverse reactions if consumed. That being said, butter can last past their expiration date if stored properly.
The USDA advises storing butter in the refrigerator as it stays fresher longer in cold temperatures. You may want to store unused butter from the grocery store in the freezer to increase its shelf-life.
Additionally, you should always inspect the butter for any changes in texture, color, or smell. If you notice any odd smells, discoloration, or a consistency that is not smooth, it is recommended to toss the butter.
How can you tell if butter is spoiled at room temperature?
If the butter has been left out at room temperature for too long, it can spoil and develop a rancid smell. Other signs that butter may be spoiled include a change in color or texture, such as a yellowing or a greasy texture.
Spoiled butter may also have a sour taste. When in doubt, it’s best to toss out old butter that has been left at room temperature.
