    I just checked the Jif label and it states that "no refrigeration is required after opening". It also does not have an experation date. I would not recommed eating it after about 2 years though (unopened and stored) As for the food poisoning, if bacteria finds it's way into the jar then you could get food poisoning from it (or any other food for that matter).

    Natural peanut butters, however, do have experation dates and usually must be refrigerated.

    You get a hankering for a peanut butter and jelly sandwich, and after rooting around in the pantry you discover a neglected plastic jar of PB — score! But you’re a little worried about how long it has sat back there consorting with the pretzels. You unscrew the brightly colored lid and peek inside — no green or white fuzz — and a timid sampling confirms it still tastes good. It’s time to slap together a big, sloppy PB&J.

    Peanut butter is gooey and delicious, yet it can remain at room temperature for months without spoiling. Low moisture levels and high oil content keep this butter from going bad for quite some time, but don’t go ignoring that expiration date just yet. Peanut butter can go rancid in about a year and lose its flavor. While fungi and bacteria won’t ruin your peanut butter, oxygenation eventually will.

    Well, I did go on a canoe trip before and one of the groups brought peanut butter along. They complained that their peanut butter tasted like plastic . . .

    I'm pretty sure it was a canoe trip anyway. I am also pretty sure that peanut butter was old.
