There are no apparent ill effects from my mealworm oatmeal bar experience. I am still feeling a little queasy from the thought but I'm not actually sick in any way. I'm trying to figure out a food that feels safe to eat today. I've always been a picky eater and easily grossed out. If I've gotten sick from a food I can't even look at it again for a long, long time.
It didn't help matters that I'd recently read about some really creepy parasites. They're like something out of a sci fi movie!
I'm considering just mailing the thing to Quaker so they can see that their "best by" date isn't anywhere near the "best by" label and is difficult to even read. Even so, you expect staleness--not worms!
