If you read the ingredient labels on the food you eat, you often see vague items like "natural flavoring". At least in one case, you probably don't want to know what that really means.

It's not some Frankenfood concocted by a Clark Griswold food additive dreamed up in a lab, it IS natural, but the source is rather distasteful. According to WFTV.com, Castoreum is found in many foods, mainly as a vanilla substitute; but where does Castoreum come from? The source of the flavoring is the anal secretions of the beaver.

I was a bit suspicious, so I checked the accuracy of this disgusting report on Snopes. Not only is the use of beaver glands true, it generally recognized as safe by the FDA. I'll bet you're going to read those ingredient labels a little more closely now.
