Is my unsealed, with closed lid, jar of Peanut butter o.k. to eat?

I don’t know what the scientific answer is, but I know I’d have no problem eating it.

I think Peanut Butter has a fairly long shelf life. You should be good. Maybe check for mold first? To be safe.

I’d check both the jar and the cracker packaging for an expiration date.

Oh, I forgot to comment on the crackers. I’m gonna bet those will be “safe” to eat. But, they probably won’t taste very good.

Totally fine, PB lasts forever.

The crackers should be fine.

The PB will be safe to eat but since it contains oil, there’s a chance that the oil might have gone rancid.

If so, it’s not necessarily dangerous or anything but might have a slight “off” taste.

Smell it first and you would likely be able to tell if the oil has turned.

It would be ok still, but just not as tasty. If it tastes good to you, then everything’s good.

I have had PB turn on me but it was probably around a year or more. I just didn’t enjoy dealing with that slight off taste so I tossed it.

Ever since then, I always keep my PB in the refrigerator.

Another item which can turn is Potato Chips (again because of the oil). They can still be eaten (in terms of safety) but they just don’t taste as good.

If there’s a particularly good sale on them, I’ll stock up but then sometimes forget about one or two bags in the back of the pantry.

PB probably perfectly okay. Your nose would know if it were spoiled. If the crackers still crunch, they’re fine. If they’re soft, yuck.

I’m not eating old unrefigerated peanut butter because it can have Aspergillus which can be very toxic and undetectable. It can’t be removed by cooking either. I would toss it.

Update I find that squeezable peanut butter and individual packages of single use peanut butter lasts longer than a big jar.
