Eating Bugs: The Secret Behind the Red Food Coloring Carmine

Angela Tague
Do you enjoy relaxing with a glass of red wine?

You may want to stop daydreaming about the indulgence for this bit of news: Some FDA approved red dyes originate from insects.

Yes. Bugs.

Now it's time to scour the pantry. Take a peek at that box of red candy, strawberry cake mix or bottle of red wine vinegar. If you notice the ingredients cochineal extract, carminic acid or carmine -- all common red dyes -- on the label, they contain dried bugs.

Red bugs in My Food

Red dye made from carminic acid is derived from the female Dactylopius coccus costa, or cochineal insect. Although the Food and Drug Administration requires the bud-derivative to be pasteurized or treated with a similar process to eliminate Salmonella microorganisms, the thought of eating foods tinted red with insect innards may make your stomach turn -- or worse, cause an allergic reaction.

Red Dye Can be Dangerous

After accepting the bug-component of cochineal extract, carminic acid or carmine, take heed if you experience allergic reactions to food additives. In a 1997 study by the Department of Internal Medicine, Division of Allergy at the University of Michigan at Ann Arbor researchers confirmed an allergic reaction to a carmine-dyed frozen treat. Within three hours of eating a frozen Good Humor SnoFruit treat dyed with carmine, a 27-year-old subject reported anaphylaxis, nausea and hypotension with tachycardia.

Not a New Concept

Native Americans and Mexicans have been using the natural red bug dye for centuries. When carminic acid is mixed with natural dyes from other sources, fade resistant red, purple and blue dyes are created and used to color fibers for cloth making, according to the University of California at Los Angeles' The Midred E. Mathias Botanical Garden. Today, Peru and the Canary Islands are top producers of carminic acid .

Cochineal extract, carminic acid or carmine also add color to non-food items. Before picking up a tube of lipstick, compact of eye shadow or bottle of shampoo peek at the ingredient list. You might be surprised to find bugs in your favorite products.

    "Native Americans and Mexicans have been using the natural red bug dye for centuries."

    They use it for their blankets etc as a dye but not for food coloring I take it.

    Interesting article. It doesn't bother me because we already eat things produced by bugs. Honey is the biggest example. Comes from the insides of bees but nobody seems to be bothered by that. To my way of thinking there is a difference between that and having your food infested by bugs that are eating the same thing you are.
