An open jar of peanut butter stays fresh up to three months in the pantry. After that, it's recommended to store the peanut butter in the fridge (where it can maintain its quality for another 3-4 months). If you don't refrigerate, oil separation can occur.
"Also, when you don't refrigerate natural peanut butter, oil separation can occur, requiring you to mix it well upon using." The flavor does not change when refrigerating, though. "When the oil gets rancid, it will give off an unpleasant smell," Dr. Young notes of when peanut butter begins to spoil.
According to The National Peanut Board, an unopened jar of peanut butter can last six to nine months at room temperature. Once opened, they say that it can last two to three months in the pantry before you should move it to the fridge, where it can maintain quality for another three to four months.
In general, commercial peanut butter does not need to be refrigerated. Opened jars of your everyday, processed peanut butter can sit in a normal pantry for up to three months after opening. Keeping the peanut butter at room temperature also has the added bonus of making it more creamy and spreadable when you use it.
You'll be able to tell fairly quickly tell if your peanut butter has turned rancid: It will have a metallic, bitter and almost stale smell. It may also be darker and dried out in appearance. If it's natural peanut butter, it may be moldy. Any of these features signal it's time to throw away your jar of peanut butter.
It's hard for peanut butter to spoil because it's mostly fat—that's what makes it taste so good. Natural peanut butter only contains peanuts and sometimes salt, and while some nut butters also contain oil, sugar or stabilizers, there's nothing there to add any water.
It is OK to eat peanut butter every day, but in moderation. Do not eat more than 2 tablespoons, approximately 32 grams, a day. This protein-packed spread is made by blending roasted peanuts into a thick paste and contains various nutrients that promote good health.
Do Fresh Eggs Need to Be Refrigerated? Freshly laid eggs need to be refrigerated immediately. Fresh eggs purchased from a farmers market need to be refrigerated as soon as you get home. Per USDA guidelines, eggs should be stored at 40 degrees F or below to help minimize the risk of Salmonella.
Keep container in an area that will stay at average room temperature. Because honey is best stored at room temperature (somewhere between 64 to 75 F), keeping your container of honey on a shelf or in your pantry is recommended.
If peanuts come in contact with a pathogen after roasting, the Salmonella can survive, often for many months. Once alive in a jar of peanut butter, some Salmonella bacteria have been found to survive up to 24 weeks (Burtett, et al., 2001).
Unopened conventional peanut butter: 6-9 months, no refrigeration needed. Opened conventional peanut butter: 2-3 months in the pantry, 6-9 months in the fridge.
WHAT ARE THE WHITE SPOTS/COATING ON THE SURFACE OF MY NUT BUTTER?

Store your peanut butter container upside-down. Yes, it really is that simple. See, the liquids that separate from the solid body of peanut butter rise to the top. Storing it upside-down will force the oils at the top to travel back through the butter, mixing right in themselves.
*Never keep your bread in the fridge. The starch molecules in bread recrystallize very quickly at cool temperatures, and cause the bread to stale much faster when refrigerated. *Shop-bought loaves should be kept in an air-tight plastic bag at room temperature rather than in the fridge.
Small bits of peanut skins attached to the peanut when it is ground can cause these dark spots. The dark spots in our PB Bites look like chocolate chips. They are not peanut skins (which are reddish in color).
In Europe it's a health risk to store eggs in the fridge. In Australia, it's a health risk to store them out of the fridge. Who is right? The answer is all about Salmonella, the general name for about 2,000 types of bacteria that lead to food poisoning.
British authorities actually discourage refrigerating eggs on the theory that chilling and then warming could create condensation, which would allow salmonella to penetrate the shell.
Mayonnaise. You may buy mayonnaise off a non-refrigerated shelf, but the second you pop the top, you must put it in the refrigerator. In fact, the USDA recommends opened mayo be tossed in the trash if its temperature reaches 50 degrees or higher for more than eight hours.
Peanut butter is high in protein and healthy fats, which can also help reduce blood pressure levels.

A peanut sensitivity is a digestive issue in which your body will produce an inflammatory response to the particular proteins in a peanut which can lead to discomfort, even severe, without the need for immediate medical attention.
