For any of you with natural peanut butter in your cupboard, you might want to go put it in your fridge instead.
Okay, so maybe the precaution is a little extreme since nothing has been officially proven, but some are starting to speculate that peanut butter may sometimes carry the carcinogen aflatoxin, which can cause cancer.
Since peanut shells are pretty soft, it can allow fungus to penetrate through the shell and into the nut. Sometimes this fungus may be carrying aflatoxin. Although it has not been completely proven to cause cancer, it has been shown in developing countries, where nuts and grains are grown out of soil without strict quality regulations, to cause liver cancer.
It is more likely for natural peanut butter to have this because of the fact that it is less processed and has a shorter shelf life. Because it's natural, it is more likely to grow the mold that contains the harmful carcinogen. Hence putting it in your fridge to help prevent mold growth.
I'm not too worried, considering it hasn't been made into a big stink (yet). For more information, check out the original article from Slashfood here.
