A non-profit watchdog group is raising concerns about how some yogurt companies color their products.
Cochineal insects are valued for their vibrant red color when crushed. Now the Center for Science in the Public Interest says Dannon should get it out of its yogurts.
The group says dozens of consumers have complained that the bug coloring, called carmine, has caused vomiting, hives, and swelling.
"The average yogurt eater sees the redness and thinks strawberries. There's a picture of a strawberry on the label, not an insect," said the Center's Michael Jacobson.
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 shelf life of the product."
Last year, Starbucks said it would stop using the bug dye in products like its Strawberries & Cream Frappuccino.
