The expiration date found on packages typically indicates the time at which the product will no longer be optimally fresh and have the fullest flavor, making expired pistachios less enjoyable to eat.
In addition, once pistachios are expired, they can become contaminated with bacteria or fungi. These microorganisms can cause illness if consumed, and eating expired pistachios can lead to symptoms such as abdominal pain, nausea, vomiting, and diarrhea.
Thus, it is important to always check the expiration date before consuming any food product, including pistachios.
How long does pistachios last unopened?
Pistachios last a long time if they are stored in an unopened, sealed package in a cool, dry location. Their shelf life can range from several months to over a year, depending on the quality of the product and how they were stored before being sealed.
For the most optimal storage and longest shelf life, the pistachios should be stored at room temperature and kept away from any sources of heat or moisture. Additionally, if the package has been opened, the pistachios should be transferred to an airtight container or resealable plastic bag and placed in the refrigerator to slow down their rate of degradation.
How do you know if pistachios have gone bad?

Nuts can also be stored in the freezer for up to six months. This can help them maintain their freshness longer.
Which nuts have the longest shelf life?
Generally speaking, the nuts with the longest shelf life are those that are stored in airtight containers in a cool, dry place. These include peanuts, almonds, walnuts, and pecans. Shelled nuts tend to have a longer shelf life than nuts with shells due to their decreased vulnerability to moisture and oxygen.
Nuts with a high oil content, such as walnuts, can spoil sooner than those with a lower oil content, and should be stored in a refrigerator or freezer if possible. Nuts stored in their shells tend to stay fresher longer due to the protection of their shell.
Additionally, blanched or roasted nuts have a shorter shelf life than raw nuts. If stored properly, nuts typically will last for 6-12 months.
Are rancid nuts carcinogenic?
No, rancid nuts are not carcinogenic. The practice of storing and preserving nuts in a way that allows them to become rancid is not considered to be a health risk and does not pose a carcinogenic risk.
Rancid nuts, however, may not have the same nutritional value as freshly-harvested nuts, and may contain harmful bacteria or toxins that can cause adverse health effects. Therefore, it is best to avoid consuming rancid nuts as they can be harmful to your health.
Additionally, it is important to store nuts in an airtight container at room temperature and away from light, heat and moisture to help prevent them from becoming rancid.
