Is it safe to eat expired peanut butter

Date says November 2009.

Is that a sale by date?

It actually increases in protein with age. I would say let it stay out for another month or two.

Depends what is in it...

Probably not. Supposedly some mold grows on peanuts that releases a carcinogenic toxin. 100% serious. Read the article like yesterday.

* "Sell by" date. This tells the store how long to hold the food for sale. Don't buy the product after this date. Food sold on the "sell by " date can still be eaten later. For example, milk generally is safe and wholesome 7 to 10 days after the date on the label. This is a "sell by" date for the grocery store, not a "use by" date for the consumer.
* "Freshness" date or "quality assurance" date. This date suggests how long the manufacturer thinks the food will remain at peak quality. The label might read "Best if used by November, 2005." The product still may be used after this date, although it may no longer meet the company's standard for freshness.
* "Pack" date or "package" date. This is the date the food was packaged or processed. With this information, consumers can decide which package is fresher. Fresh meat is labeled with a pack date. Do not buy ground beef packaged three days ago when a package is available that was packed today.
* "Expiration" date. This is the last date the product should be eaten. It might read, "Do not use after March, 2005." Always discard food that has passed the expiration date.

dont, youll die

if you already ate some...

RIP

Last kid that did that got the aids.

Cheap insurance... Buy a new one for three bucks? Is it really that hard

go for it and tell us what happens ;)

when the fats in p-nut butter get old, they combine with oxygen. This process of oxygenation is called "going rancid". Rancid is like being moldy or spoiled or otherwise nasty.

$2 for a tasty new jar. I recommend Trader Joe's if they got one near you.

Pretty sure that means expired peanut butter is fine unless it smells/tastes rancid. However I wouldn't risk it simply due to how it would taste since it's almost surely rancid. A few days sure but 5 months?

This.

If you opened it before: no
If it is still closed: sure
