(CNN) -- If you've never stopped to think about how the food you eat gets its color, maybe it's time you did!

A nonprofit health and consumer watchdog group is raising concerns about how some yogurt companies color their products -- particiularly, using bugs!

Cochineal insects are valued for their vibrant red color when crushed.

Last year, Starbucks said it would stop using the bug dye in products like its strawberries and cream frappucino.

Now, the Center for Science in the Public Interest says Dannon should get it out of its yogurts.

"A company like Dannon should be coloring its strawberry yogurt with strawberries and not some insect extract," CSPI Executive Director Michael Jacobson said.

They say Dannon is being deceptive.

"The average yogurt eater sees the redness and thinks strawberries. There's a picture of a strawberry on the label. Not an insect," Jacobson said.

The group says dozens of consumers have complained that the bug coloring, called carmine has caused vomiting, hives and swelling.

In a statement, Dannon said: "Carmine is a safe, FDA approved, vivid red color that many food makers use, including Dannon in some of our products because it delivers the best color throughout the shelf-life of the product."

Dannon says if consumers want to avoid it, they can just look for it on the label.
