I visited a peanut butter plant in dothan, alabama-had a friend at fort rucker-and watched as they opened cases of outdated pb and scraped it into the new stuff on the line. It gets heated and renewwed , or diluted, or something. Even the freaking vegetables (legumes) are not terribly wholesome in the processing. FDA limits for rodent feces and insect parts in flour are substantially greater than zero. Beer is safe, and the insects that you gather in your yard-all else is in qusetion if processed.
