Anaphylaxis from Gummy Bears
Scurlock et al outline the case of a young girl who experienced anaphylaxis after eating gummy bears. She was tested for allergy to the various ingredients but all results were negative.
The authors concluded that she was reacting to the added "natural and artificial flavors" but because the manufacturers would not disclose the ingredients within these it was not possible for them to identify the exact culprit
The authors write: "Currently, vendors are reluctant to reveal the variable components of these flavorings. In light of the potentially life-threatening complications that can ensue from consumption of these products, cooperation with industry and improved labelling of all ingredients is essential."
