5. The Bugs Are on Purpose

In a restaurant, finding a bug in your food is cause for a refund. In the mass-produced-food industry, it's sometimes cause for a purchase.

You know all those pink foods that draw you in with their pretty, appetizing, fruitlike color? Lots of them, including Dannon strawberry yogurt and Ocean Spray pink-grapefruit juice drink, are made with bugs [source: Schlosser].

You won't find "bugs" in the ingredient list, of course. The critters are in the form of a common food coloring called cochineal extract (or sometimes carmine or carminic acid). Cochineal gets its red color from an insect called Dactylopius coccus Costa, which feeds on red cactus berries.

To make cochineal, the insects are dried and then ground up into a powder. You'll find it in lots of processed pink, red or purple foods.
