Using cashews that have gone bad is not a good idea because it could cause food poisoning. Rancid cashews can produce harmful bacteria and fungi that are risky to consume. It may result in diarrhea and vomiting.

How To Tell If Cashews Have Gone Bad? 

1. Appearance

You can tell if the cashews are worse by looking at them. If they have changed in color or become very dark, don’t eat them because they are rancid.

2. Smell

If you don’t understand the appearance and cannot be in a decision, is it bad or not? Just check the smell.

If your cashews smell unpleasant, acrid, or sour, they have been trashed and are no longer edible. If it is in the freezer, let them in a cool and dry place and then see if its smell is pleasant. If not, discard them.

3. Taste 

Sometimes, smell and appearance cannot indicate whether cashews are good enough. You could taste cashews slightly if you have doubts.

Cashews have a mild flavor and are creamy with a rich texture. They are no longer fresh, though, if you eat some cashews and they taste bland or unpleasant. It means it is time to discard them and get a new pack of cashews.

4. Touch

You can tell by touching cashews whether it is worse or not. If cashews are hard to the touch and crunchy, they are still good; however, if they are soft and flaking, they have gone rancid.

You can check cashews by gliding the knife through cashews. If it is soft or feels sweaty or oily, it is rancid and not recommended to eat.
