One of the main symptoms that people with a food dye allergy suffer from is gastrointestinal symptoms. These may include diarrhea, gas, or bloating right after ingesting foods with dye in them. Sometimes vomiting can occur. The vomiting usually stops once the food dye has made its way through the system. These symptoms usually pass after a short amount of time and need no intervention. If food dye is continually being ingested and vomiting or diarrhea continues you may need to watch out for dehydration.

There is a blood test to check for carmine and annatto dyes. There are also food additive patch panel tests or a skin prick test that can be used for diagnosing as well.
