FDA says some bugs, mold OK for foods

As the list of foods recalled salmonella outbreak continues to grow, you might be surprised to learn the FDA actually allows a certain amount of contaminants in the food supply.

Bugs, mold, rodent hairs, and maggots are all okay if not found in big numbers.

The FDA says canned mushrooms, for example, may have "20 or more maggots of any size per 100 grams."

The next time you down a beer, keep in mind 10 grams of hops could have up to 2,500 plant lice.

CNN reports that peanut butter, the food that initiated the scrutiny, can actually contain about 145 bug parts for an 18 ounce jar.
