The Center for Science in the Public Interest has asked Dannon to take out bugs from its yogurt, that are being used as food coloring, officials said.
The bug coloring, known as Carmine, is valued for the vibrant red color it gives off once the bugs are crushed.
Officials from CSPI said that the bug coloring can be found in Dannon's strawberry, cherry, boysenberry, and raspberry varieties of its "Fruit on the Bottom" line. It can also be found in of the yogurt company's strawberry flavored Greek yogurt.
According to CSPI officials, dozens of customers have complained that the bug-based coloring has caused vomiting, hives and swelling.
"...When I buy strawberry yogurt I'm expecting yogurt and strawberries, and not red dye made from bugs," said CSPI executive director, Michael F. Jacobson.
In a statement, Dannon said, "Carmine is safe and FDA approved."
CSPI is sponsoring an online petition on Takepart.com to urge Dannon to replace the the bug dye with more fruit advertised on the label.
