Does peanutbutter spoil

Answer 1

Yes, just like any other food.

Answer:

Even better than that. Peanuts can be inflected with black mold (Aspergillus flavus and Aspergillus parasiticus) which produces afflotoxin, a potent carcinogen.

Answer 2

It can, but it would have to have some contaminate added. Peanut butter has a natural bacteria fighter in it that keeps it from spoiling. The only thing that happens is it may separate, the jar will look like an oily paint. That's all you need to do is stir it. Peanut butter has a very long shelf life.

Answer 3

Eventually the oil goes rancid and it will taste horrible.

However I have kept and used peanut butter for a very long time past the expiration date without any sign of rancidity. On the other hand I have bought some "no name" brands of peanut butter that already tasted rancid when I first opened them the day that I bought them...

However rancid peanut butter will not make you sick.

There are some molds and other microorganisms, some of which are toxic and will make you sick, that grow on peanuts and will also grow in peanut butter.

So yes peanut butter can go bad, but I eat lots of it and never encountered a problem (other than rancidity in "fresh" peanut butter, as I said above).
