Even when you expose cashews to extreme conditions like sunlight, heat and air, they can accelerate rancidity. Not storing them correctly can also make the cashews expire.

Most pre-packaged cashews will have a best-by date, which will tell you how long you can leave the package unopened in your pantry. This is typically 6 months to a year. Once the package has been opened, roasted cashews will last about 2 weeks in the pantry or a month in the fridge.

Raw cashews are unsafe
